Abstract: Plant molecular biology is the theoretical foundation of plant genetic engineering, and has important significance for guiding crop genetic improvement and breeding of new varieties. Summarizing the paper production about plant molecular biology in China, objectively evaluating Chinas fundamental research level and impact in this area, understanding its development status and changing trends, are of significance for independent innovation of seed industry in China. Taking Web of Science database as literature resources, this study collected high-level research literature enunciable on plant molecular biology from 2006-2015, analyzed the status and development trends both on published paper quantities and their impacts by bibiliometrics method, and compared with the major countries in this research field. Besides, this paper also described the distribution character of outgoing journals, productive authors and high yielding affiliations, financial source and international cooperation situation. At the same time, it revealed the research hot spots of plant molecular biology in China. The results show that during the past decade, 3 841 high-level literatures (IF≥4.0) on plant molecular biology were published by Chinese scientists, accounting for 16.74% of the global total, ranking the second place in the world. The annual publishing quantity presented a tendency of yearly increase. Since 2012, China ranked the second in the world. The gap between China and the United States reduced day by day. The paper impact was also been improved, but there was still bigger gap between China and the leading counties like the Netherlands and United Kingdom. In conclusion, this study would clarify the global development configuration of plant molecular biology, excavate the leading affiliations and scientists in this area, and ravel out the cooperative relationship between China and the other countries, trace the financial source and explore research hot spots. It would also assist Chinese plant molecular biology scientists to discern their international standing in this field, find out their own advantages and potential, discover existing problems and gap, so as to provide references for the disciplinary development of plant molecular biology.
