CYP71 — Lactuca sativa

Summary

LsCYP71, located on chromosome 2 of garden lettuce (Lactuca sativa), encodes a protein 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, and the regulation of meristem organization and root meristem size. It has been linked to traits including plant cell size, sulfur content, anthocyanin content, flowering time, disease tolerance, and leaf and root morphology. Associations with sepal formation, leaf shaping, trichome differentiation, carpel and stamen development, and multidimensional cell growth have also been observed. The encoded protein localizes to the nucleus, cytoplasm, euchromatin, heterochromatin, the CAF-1 complex, and the Cul4-RING E3 ubiquitin ligase complex. Related genes in other species are linked to genome stability, nucleosome assembly, and meristem development.
