GAI (LSAT_V11C400162690) — Lactuca sativa
Summary
LsGAI, also known as GAI, is a lettuce gene on chromosome 4 that encodes a DELLA protein, a member of the GRAS transcription factor family characterized by the DELLA_N domain. The product exhibits gibberellin binding, phytochrome binding, and transcription corepressor binding activities, and is associated with the regulation of gibberellic acid-mediated signalling, response to karrikin, and detection of light. LsGAI has been linked to numerous agronomic traits, including leaf length-to-width ratio, grain yield, fruit quality, seed coat hardness, total soluble sugar content, and root width. It is also connected to dwarfism, stress tolerance, longevity, and thermomemory. Related genes in other species link the family to growth regulation, gibberellin homeostasis, and abiotic stress tolerance.
