During the different development stages and interaction with environment, plant structure and morphology will change dramatically. These changes are controlled by a set of genes expressed in specific spatial and temporal profile. The precise “switch on” is plant tissue specific promoter. Due to the tissue specificity of these promoters, there are currently a great deal of researches on model plants (Arabidopsis thaliana, Nicotiana tabacum), food crops (Zea mays, Oryza sativa, Triticum aestivum, etc.) and economic crops (Anemone vitifolia Buch, Brassica napus, Arachis hypogaea, etc.). This paper reviewed the advances of plant tissue specific promoters and prospected innovative approaches for isolation and application of tissue specific promoters.

In order to explore the relationship between sugar metabolism with related enzyme activities and gene expression during the development of tobacco leaves, the contents of glucose, fructose, sucrose, reducing sugar and total soluble sugar in the development of tobacco leaves were measured; and the key enzyme activities and gene expression levels related were analyzed with the tobacco variety Qinyan 96 as material. The results showed that the contents of glucose, fructose, reducing sugar and total soluble sugar increased first and then decreased during the development of tobacco from 65 d to 115 d after transplanting. When the tobacco leaves matured (95 d after transplanting), the contents of soluble sugar (except sucrose) reached to peak value. The content of sucrose showed a bimodal fluctuation and the tobacco had the lowest sucrose content at maturity. During the topping to proper maturity of tobacco leaves, SPS and AI enzyme activities contributed the most to the accumulation of soluble sugar in tobacco leaves. When tobacco leaves were from ripe to overripe, AI was mainly involved in the regulation of sugar metabolism in tobacco leaves, while SS and SPS played important roles in the accumulation of sucrose. NtINV had a greater regulation on tobacco sugar metabolism in the stage from topping to maturity, while NtSS and NtSPS played major roles in regulating sugar metabolism in tobacco leaves from proper maturity to overripe. Sugar metabolism related genes regulated the activity of related enzymes through the molecular level and then regulated the sugar metabolism of tobacco leaves.

In order to investigate the factors influencing pig live performance, this paper took Duroc, Landrace and Large Yorkshire as the objects and tested the back fat thickness, eye muscle depth and eye muscle area of each experimental pig by B-mode equipment. The data were analyzed by correlation analysis and variance analysis, and regression equation was built. The results showed that measurement of pig live performance by B-mode equipment was affected by breed type, final weight; related to operation skill of the tester, and also limited by the test equipment. There were no significant differences between back-fat thickness testing results by parallel viewing and cross viewing. So these 2 methods could replace each other. Above results provided scientific basis for standardizing the technical regulations for production performance measurement of breeding pigs.

With the wide use of antibiotics in veterinary clinic, the number of drug-resistant strains is increasing year by year, so the research on the mechanism of drug resistance has become a hot spot. Resistance gene cfr (chloramphenicol-florfenicol resistance) can encode to synthesize 23S rRNA methylation enzyme of bacteria. This enzyme can affect the combination of antimicrobial agents with transpeptidase and make bacteria resistant. The strains carrying cfr gene were resistant to chloramphenicol, linamide, truncated pleurodin, streptavidin A and oxazolidinone, which resulted in multidrug resistance to bacteria. Therefore, the study on the mechanism of action and transmission of drug resistance gene cfr is the key point for the backerial resistance research. In this paper, the discovery, harm, drug resistance mechanism, transmission mechanism and prevalence of multidrug resistance gene cfr in different types of bacteria were reviewed. The problems existing in present research, and suggestions for future development prospects were discussed. It provided reference and basis for the further establishment of cfr gene detection network, the development of new drugs and blocking the transmission of cfr gene.

The quantitative studies on morphological characteristics of rice root system are of great significance for improving farmland management, rice selective breeding and genetic improvement. In recent years, along with the rapid development of phenotype technology, image processing technology could be used to measure and analyze the growth of rice root system. At the same time, combined with fertilization, irrigation, light, temperature control and environmental monitoring technology, it has become a new technological means for rice breeding and functional genomics research. And the root system image segmentation technology is one of the key foundations for the subsequent phenotypic group analysis. The segmentation is very difficult, because the rice root system images have the characteristics of low contrast, low SNR and complex texture. Aiming at this problem, the paper firstly studied the main-branch connection algorithm, local threshold segmentation algorithm based on the morphological characteristics, and adaptive threshold segmentation based on morphological characteristics, and then performed segmentation and comparison on rice root system images. The results showed that although the main-branch connection algorithm retained a large number of root details, its structure was slightly chaotic and burr phenomenon was serious; the local threshold segmentation algorithm based on morphological features could retain more root details, but the contour fracture was more severe; adaptive threshold segmentation algorithm could improve image continuity, burr phenomenon was controlled, fine roots would not be preserved. These 2 algorithms were combined into a integrated algorithm suitable for image segmentation of rice surface root system. Thus, relatively ideal segmentation results could be obtained, which would provide important basis for follow-up studies on phenotypic traits of rice root system.

In order to establish a collision model between seed cotton and working parts of harvester and processing machine, this paper measured and analyzed restitution coefficient of seed cotton by recovery coefficient measurement device based on kinematics equation. The restitution coefficient of seed cotton was determined for different drop numbers using a drop test apparatus with drop heights ranged from 200~400 mm, and the material thickness was ranged from 2~6 mm. The collision materials were Q235 steel, aluminum alloy, organic glass and rubber. A complex orthogonal design of L8(41×24) was conducted to systematically investigate the above factors effected on restitution coefficient of ‘Zhongmian 6913’ seed cotton, harvested by brush-roller type stripper cotton harvester. The single-factor experiments were carried out under the condition of different collision materials, material thicknesses and drop heights. The results showed that the significance of above factors to restitution coefficient of seed cotton were collision material > drop height > material thickness > seed cotton number. Among them, the seed cotton number had non-significant effect on restitution coefficient. The results of single-factor experiment indicated that the order of recovery coefficient between seed cotton and collided materials was Q235 steel> aluminum alloy> organic glass> rubber. In the test scope, the restitution coefficient of seed cotton decreases almost linearly with the increase of drop height, and firstly increase significantly then slowly with the increasing thickness of collided material. The above results might provide theoretical references for rational design and simulation of seed cotton harvester and related important working parts.

Tuber morphological structure model is an important content for studying ‘function-structure potato’ model. Taking potato variety ‘Favorita’ as material, this paper carried out a field fertilizer test in potato growing seasons of 2016 and 2017. On the basis of tuber morphological-structure parameters and organ biomass data collected in the experiment of different nitrogen and potassium levels and different additional nitrogen levels, the morphological-structure models of potato tuber were built through dissecting the quantitative relationship parameters among tuber morphological-structure, organ biomass and physiological development time, and based on the internal connections of morphological-structure parameters. These models were then validated with an independent data set collected in the experiment of different based nitrogen levels. Except for index of tuber shape, tuber length, tuber width, tuber thickness, and specific tuber weight of potato had higher accuracy. These models could be used to simulate tuber structure under different fertilizer application levels.

Amino acid variation and nutritional value of Xinjiang Jun jujube from 11 counties of Xinjiang were preliminarily verified, which provided theoretical basis for better utilization of jujube resources. Using Jiaocheng Jun jujube from Shanxi province as a control, the amino acid data of Xinjiang Jun jujube were analyzed by fuzzy recognition method, variability, and system clustering method. The results suggested the total content of amino acid in Xinjiang Jun jujube was superior to that of Jiaocheng Jun jujube. There is a big difference in amino acid composition content of Jun jujube from 12 different production areas, especially amino acids of Val, Leu, Thr, Lys and Phe. The closeness degrees of protein amino acid respect to model amino acid of different production areas were basically the same. The scores of ratio coefficient of amino acid (SRC) of Xinjiang Jun jujube were superior to that of Jiaocheng Jun jujube. The ratio coefficient of amino acid (RC) of Val from different production areas was the lowest, which mean Val was the first limited amino acid. The Jun jujubes from different production areas could be divided into three categories by cluster analysis. The better ones after protein quality evaluation were Awat, Qira and Akesu. The amino acid composition of Jun jujube protein in 11 counties of Xinjiang have their own characteristics, and the protein composition of Jun jujube in Awat, Qira and Akesu meet the nutrition requirement for protein of human, which should be further utilized.

With the rapid development of economy and society, heavy metal contamination of cultivated soil has seriously influenced food security and human health. Based on the data of heavy metal in cultivated soil in eastern China collected from documents, the degree of heavy metal pollution of cultivated land in eastern area was evaluated, by means of semi-variogram analysis, Kriging interpolation, single factor pollution index, Nemerow comprehensive pollution index, and geoaccumulation index. The conclusions showed as follows: the pollution of Pb was the most serious one; the mean value of Hg was 2.8 times higher than background value of element Hg in Chinese soil. Almost 30% of eastern area was under the middle pollution level. The pollution of Cd was the second serious one, and results of semi-variogram analysis indicated Cd was the most influenced by human activities. In addition, the mean value of Cd was 2 times higher than the background value of Cd in Chinese soil. Over 50% of eastern area was under the firing line of Cd pollution. Cultivated soil in Guangdong province may be the key region of heavy metal integrated pollution because Nemerow comprehensive pollution index in Guangdong was the highest (0.854) and Kriging interpolation revealed high value area of As, Cd, Hg, Pb distributed in Guangdong province.

Taking peanut variety Yuanza 6 as material and adopting a split plot experiment, this paper investigated the changes in multiple indexes of summer-planting peanuts under different planting densities and planting modes, including group flowering phenology, group pod pegs formation and pod formation, yield traits etc., and discussed the effects of rational close planting on peanut group reproductive growth and yield. The results showed that comparing to planting density of 1.80×105 holes/hm2, the first flowering of peanuts grown at 2.25×105 holes/hm2 planting density would delay 1~2 d. The number of nodes on the first pair of lateral branches within 10 cm from base decreased by 10.29%; while, effective branching ratio increased by 8.50%; full fruit ratio and kernel percentage increased by 3.81% and 2.25%, respectively. The flowering time of peanuts grown in wide/narrow-row-spacing planting mode was 2~3 d ahead than that of equal-row-spacing planted peanuts, and the full fruit ratio and kernel percentage increased 3.03% and 1.58%, respectively. Comparing to single-seed planting, double-seed planting increased the effective branching ratio, full fruit ratio and kernel percentage by 10.60%, 3.70% and 1.43%, respectively. Under the condition of double-seed planting, wide/narrow-row-spacing planting mode with plant density of 2.25×105 holes/hm2, the peanuts had the highest amount of total group flowering (1 873.31×104 flowers/hm2). The numbers of group gynophores and groupfruit were also the most, reaching 1 365×104/hm2 and 488×104/hm2, respectively. Yuanza 6 was highly tolerant to compact planting. Therefore, in summer-planting appropriately increasing the planting density could effectively improve yield and perfect pod commodity.

In order to explore the causes of continuous cropping obstacles in garlic, this paper selected the soils in which garlic was grown for 0 year (control), 5 years, and 10 years as research objects, and researched the changes of soils nutrients, soil microorganism quantity and enzyme activities. The results showed that with the increasing of continuous cropping years, garlic yield dropped significantly compared with the control. The production decreased by 31.1% and 40.8% in 5 years and 10 years of continuous cropping soil, respectively. Soil pH increased significantly, while soil available potassium, ammonium nitrogen, nitrate nitrogen and soil organic matter decreased under long-term continuous cropping. The quantity of bacteria and actinomyces decreased, while that of fungi increased．The activities of urease, saccharase and catalase in soil tended to be decreased within 10 years of continuous cropping, indicating that long-term continuous cropping altered the soil nutrient. In conclusion, after long-term continuous cropping, the yield of garlic and enzyme activity decreased, soil pH increased, and the microorganism composition and structure were altered. It is suggested that organic fertilizer was applied to improve the enzyme activity and balance the soil microbial community structure soil property.

Zinnia elegans is widely used in landscaping. Confronting potassium (K) resource shortage in China, it is necessary to clarify the optimum amount of potassium application and improve potassium utilization efficiency. This paper studied the effects of different potassium application treatments (0 mg/kg, 100 mg/kg, 200 mg/kg, 300 mg/kg and 400 mg/kg) on growth and bloom of Zinnia elegans by pot experiments, so as to provide theoretical basis for the rational application of potassium fertilizer in the cultivation process of Zinnia elegans. The results indicated that potassium application was beneficial for increasing plant height, leaf number, shoot dry weight, root dry weight, number of flowers and flower diameter. All these indexes showed a tendency of increasing first and then decreasing with the potassium level rising. When the potassium level was 300 mg/kg, these indexes reached the highest level, then declined at 400 mg/kg, but still higher than those of the control. Under this experiment condition, 300 mg/kg was the most appropriate potassium level to Zinnia elegans for its growth and bloom.

The nutrient contents of Auricularia auricula produced at different areas are different. Therefore, it has practical value to identify the producing areas of A. auricula. This paper selected 8 kinds of A. auricula from different producing areas; analyzed them by Fourier transform infrared spectroscopy (FT-IR) two-dimensional correlation infrared (2D-IR) spectroscopy; and identified them with hierarchical cluster analysis (HCA). The results showed that fourier transformed infrared (FT-IR) spectra of 8 samples resembled extremely in holistic spectral profile, and their partial correlation coefficient was no less than 0.955, which could not be used to distinguish their origin. In their 2D-IR spectra, the numbers of auto-peaks were different in the range of 1 730~1 400 cm-1, 1 350~1 040 cm-1 and 1 030~900 cm-1. Meanwhile, there were more differences in the intensities of auto-peaks and cross-peaks. Hierarchical cluster analysis was conducted on A. auricula with FT-IR spectra in the range of 1 700~950 cm-1, and all samples from different areas were distinguished correctly. These results demonstrated that A. auricula produced at different areas could be simply and rapidly identified by 2D-IR combined with hierarchical cluster analysis without prejudice.
