GT5 — Lactuca sativa

Summary

LsGT5, encoded by the gene LSAT_V11C200078950 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. It is associated with lignin metabolism, anthocyanin anabolism, sugar-mediated signalling, stomatal closure, seed and leaf development, and salinity response. The gene has been linked to root morphology, salt tolerance, and reduced ABA sensitivity in seed germination and root elongation. Associations with sinapoyl malate and monolignol glucoside accumulation, azoxystrobin degradation, wound response, lignification, and lignin monomer glucosylation have been reported. Studies of related genes in other species connect the family to syringin production, early flowering, increased lignin content, and azoxystrobin resistance.
