Fig. 10From: Genome-wide identification and expression analysis of the R2R3-MYB gene family in tobacco (Nicotiana tabacum L.)Relative expression level of 15 NtR2R3-MYBs in response to cold, salt, and drought treatments. Error bars are standard deviations of three biological replicates. Asterisks were used to indicate the significant degree of the expression level compared to the value of the control (*P < 0.05, **P < 0.01)Back to article page
