Abstract:

Soil with deficient basic nutrient or toxic elements is widespread globally and thus seriously affects crop production. To reduce the damage caused by soil stress, plants have evolved their adaptive mechanisms. Recent studies have found that miRNAs possess important roles in plant response to soil stress. This paper summarizes the roles of miRNAs in responding to soil stress of nutrients deficiency and toxicity elements, lays emphasis on integration of miRNAs in soil stress regulatory networks, and puts forward thoughts for improving plant adaptability to problem soils.

Key words: miRNAs, soil stress, adaptability
