MicroRNAs (miRNAs) play critical roles in the processes of plant growth and development, but little is known of their functions during dehydration stress in wheat. Moreover, the mechanisms by which miRNAs confer different levels of dehydration stress tolerance in different wheat genotypes are unclear. | Identification and comparative analysis of differentially expressed miRNAs in leaves of two wheat Triticum aestivum L. genotypes during dehydration stress
