Fig. 3From: Identification of microRNAs in response to aluminum stress in the roots of Tibetan wild barley and cultivated barleyThe identified miRNAs from roots of Golden Promise (GP) and XZ29. a Number of miRNAs in control and Al-treated roots of two genotypes. b Length distribution of total identified miRNAs. A total of 342 miRNAs were found. They were divided into three classes: known miRNAs, new members of known miRNAs and potentially candidate miRNAsBack to article page
