CYP71 — Lactuca sativa

Summary

LsCYP71, the garden lettuce gene on chromosome 4, encodes a protein with multiple molecular functions including GTP cyclohydrolase II activity, cis-trans proline isomerase activity, and binding to histones, chromatin, RNA, DNA, and proteins. This gene is associated with sesquiterpenoid metabolism, lactone anabolism, and diverse developmental processes such as leaf and sepal formation, trichome differentiation, shoot morphogenesis, carpel and stamen development, photoperiodism, and regulation of meristem organization and root meristem size. It is linked to traits including plant cell size, sulfur content, photoperiod sensitivity, aphid response, leaf and flower morphology, anthocyanin content, flowering time, disease tolerance, and seed maturation. The encoded protein localizes to the nucleus, cytoplasm, euchromatin, heterochromatin, and the CAF-1 and Cul4-RING E3 ubiquitin ligase complexes. Related genes in other species are linked to chromosome stability, shoot apical meristem differentiation, plant architecture, susceptibility to Pseudomonas syringae, secondary metabolite biosynthesis, floral transition, and plant development.
