Two bHLH transcription factors regulate PbGME1 expression to modulate ascorbate biosynthesis and salt tolerance in pear.

Salt stress severely limits plant growth and productivity. GDP-mannose-3',5'-epimerase (GME), a key enzyme in ascorbic acid (AsA) biosynthesis, has been implicated in plant stress responses, but its role in pear salt tolerance remains unclear. Here, we identified PbGME1 as a positive regulator of salt tolerance in pear...
