Gene Details:

• Gene ID:
• Gene Symbol: VaXTH1
• Gene Name: Xyloglucan endotransglucosylase/hydrolase 1
• Genome:
• Species: Phaseolus angularis

Functional Descriptions:

• Two Azuki Bean XTH Genes, VaXTH1 and VaXTH2, with Similar Tissue-Specific Expression Profiles, are Differently Regulated by Auxin.
• VaXTH1 and VaXTH2, which share a striking resemblance in their amino acid sequences. The two XTH genes exhibit essentially similar tissue-specific expression profiles, in that both mRNAs are found predominantly in the phloem fibers of growing internodes.
• VaXTH1 being expressed nearer to the top of the internode than VaXTH2. This indicates their temporally divergent expression profiles during development of the phloem fiber.
• This effect of IAA on the VaXTH1 gene is nullified in 0.25 M mannitol, which prevents cell expansion without affecting auxin action per se.
