LSAT_V11C500264440 — Lactuca sativa

Summary

LsGAI, encoded by the gene LSAT_V11C500264440 on chromosome 5 of garden lettuce (Lactuca sativa), is a DELLA protein containing GRAS and DELLA_N domains. It is associated with E-box binding, gibberellin binding, phytochrome binding, and transcription corepressor binding activities, and is linked to the regulation of gibberellic acid-mediated signalling, response to karrikin, detection of light, and plant epidermis development. The gene has been connected to numerous agronomic traits, including leaf length-to-width ratio, grain yield, fruit quality, seed coat hardness, flower number, root width, and shoot elongation under submergence. It is also associated with dwarfism, stress tolerance, longevity, and thermomemory. Related genes in other species are linked to growth regulation, gibberellin homeostasis, and abiotic stress tolerance.
