CYP707A4 — Solanum lycopersicum

Summary

SlCYP707A4 (SOLYC04G078900.3) on tomato chromosome 4 encodes a cytochrome P450 family protein with abscisic acid 8'-hydroxylase and ent-kaurenoic acid monooxygenase activities, localised to the ER membrane and mitochondria. The gene is associated with abscisic acid breakdown and anabolism, hormone and auxin metabolism, lycopene anabolism, starch breakdown, fruit abscission, seed morphogenesis, and cell wall disassembly. It is linked to seed length, shape, size, dormancy and longevity, fruit shape and size, root weight, length and hair traits, plant height, leaf relative water content, stomatal resistance and opening, chlorophyll content, proline and sugar content, drought tolerance, and self-incompatibility. Related genes in other species connect the family to ABA catabolism, nematode resistance, and susceptibility to Heterodera schachtii.
