PP2 — Cucumis sativus

Summary

CsPP2 (CSA_5G171690) on cucumber chromosome 5 encodes a MYB transcription factor with chromatin and sequence-specific DNA binding activity, localised to the nucleus. This gene is associated with the regulation of phenylpropanoid, lignin, flavonoid, and green leaf volatile biosynthesis, as well as the shikimate pathway, carboxylic acid and L-phenylalanine anabolism, and secondary cell wall biogenesis. It has been linked to anther wall tapetum development, circadian rhythm, chlorophyll fluorescence, salt response, and response to other organisms. Associations with root weight, root dry weight, and salt tolerance have been noted. Studies of related genes in other species connect the family to lignin deposition, secondary cell wall thickening in anther endothecium, phenylalanine biosynthesis, and hypocotyl elongation.
