CPD — Lactuca sativa

Summary

LsCPD (LSAT_V11C800394430) on chromosome 8 of garden lettuce encodes a cytochrome P450 protein with monooxygenase, steroid 22S-hydroxylase, abieta-7,13-dien-18-ol hydroxylase and fatty acid 2-hydroxylase activities. It is associated with brassinosteroid anabolism and homeostasis, sterol and cholesterol metabolism, steroidogenesis, and saponin and alkaloid anabolism. The gene is linked to anther wall tapetum cell differentiation, pollen exine formation, leaf development, polar cell growth, upregulation of flower development, and responses to UV-B and light stimulus. Associations with plant height, stem length, root length, pollen tube growth and root elongation have been observed. The protein localises to the endoplasmic reticulum, membrane, mitochondria and plasmalemma. Studies of related genes in other species connect the family to dwarfism, cell elongation, male sterility, flowering time, biomass production, salt tolerance and photomorphogenesis.
