Genome-wide analysis of miRNAs and their target genes in wheat cultivars with different ploidy levels under drought stress.

ABSTRACT:

Main conclusion

This study provides novel insight into the role of miRNAs in the drought resistance of different wheat cultivars, revealing a correlation between ploidy level and drought tolerance. MicroRNAs (miRNAs) are endogenous, mostly conserved, non-coding regulatory RNAs with 20-24 nt in length. Although many studies have been conducted on miRNAs that play a role in wheat drought stress response, there are no comparative studies in wheat cultivars with different ploidy levels. Here we compared miRNAs profiles of three wheat cultivars with different chromosome numbers and drought resistance levels using miRNAome and qRT-PCR analysis. Bioinformatics analysis showed that all cultivars shared 93 miRNAs in the control leaf, while 91 miRNAs were shared in stress-treated leaf groups
