PP2 — Cucumis sativus

Summary

CsPP2 (CSA_3G303630) on cucumber chromosome 3 encodes a MYB transcription factor with DNA-binding and chromatin-binding activity, localised to both the nucleus and cytoplasm. The gene is associated with regulation of phenylpropanoid, lignin, flavonoid and carboxylic acid metabolism, the shikimate pathway, secondary cell wall biogenesis, and plant-type cell wall organisation. It has been linked to green leaf volatile biosynthesis, anther wall tapetum development, chlorophyll fluorescence, circadian rhythm, and responses to salt and other organisms. Associations with root weight, cadmium and freezing tolerance, cell wall organisation, lignin and phenylalanine biosynthesis, immunity, small plant size, and altered ABA response have also been noted. Related genes in other species link the family to salt tolerance, while broader family associations include fruit shape and size, germination rate, drought tolerance, and chlorophyll content.
