Gene Details:

• Gene ID: Pbr028812.1
• Gene Symbol: PbrMYB21
• Gene Name: MYB transcription factor 21
• Genome:
• Species: Pyrus betulaefolia

Functional Descriptions:

• PbrMYB21, a novel MYB protein of Pyrus betulaefolia, functions in drought tolerance and modulates polyamine levels by regulating arginine decarboxylase gene.
• Overexpression of PbrMYB21 in tobacco conferred enhanced tolerance to dehydration and drought stresses, whereas down-regulation of PbrMYB21 in Pyrus betulaefolia by virus-induced gene silencing (VIGS) resulted in elevated drought sensitivity.
• VIGS of PbrMYB21 in Pyrus betulaefolia down-regulated ADC abundance and decreased polyamine level, accompanied by compromised drought tolerance.
• Take together, these results demonstrated that PbrMYB21 plays a positive role in drought tolerance, which may be, at least in part, due to the modulation of polyamine synthesis by regulating the ADC expression.
