CYP71 — Lactuca sativa

Summary

LsCYP71, a gene on chromosome 8 of garden lettuce (Lactuca sativa), encodes a protein containing a WD40/YVTN repeat-like domain superfamily and is annotated with GTP cyclohydrolase II activity, cis-trans proline isomerase activity, and multiple binding functions including histone, chromatin, RNA, and DNA binding. The gene is associated with sesquiterpenoid metabolism, lactone anabolism, photoperiodism, leaf and flower development, trichome differentiation, and regulation of meristem organization and root meristem size. It has been linked to traits including plant cell size, sulfur content, photoperiod sensitivity, aphid response, anthocyanin content, flowering time, disease tolerance, and seed maturation. Studies of related genes in other species connect the family to genome stability, nucleosome assembly, meristem development, and pathogen resistance, and to susceptibility to Pseudomonas syringae.
