GT5 — Lactuca sativa

Summary

LsGT5, encoded by the gene GT5 on chromosome 2 of garden lettuce (Lactuca sativa), is a UDP-glycosyltransferase with coniferyl-alcohol, hydroquinone, anthocyanidin 3-O-, and isoflavone 7-O-glucosyltransferase activities, and also annotated as a dual-specificity protein kinase with MEKK activity. It is associated with lignin metabolism, anthocyanin anabolism, sugar-mediated signalling, stomatal closure, seed and leaf development, and the salinity response. The gene is linked to root morphology, salt tolerance, sinapoyl malate and monolignol glucoside accumulation, azoxystrobin degradation, wound response, lignification, and reduced ABA sensitivity in seed germination and root elongation. Related genes in other species are associated with lignin monomer glucosylation, phenylpropanoid metabolism, and increased lignin content.
