Summary

LsGAI (GAI) on lettuce chromosome 8 encodes a DELLA protein, a member of the GRAS transcription factor family characterized by the DELLA_N domain. The protein is associated with E-box binding, gibberellin binding, phytochrome binding, and transcription corepressor binding activities. It has been linked to the regulation of gibberellic acid-mediated signalling, response to karrikin, detection of light, regulation of trichome morphogenesis, and singlet oxygen-mediated programmed cell death. Associations with agronomically relevant traits include leaf length to width ratio, grain yield, fruit quality, seed coat hardness, total soluble sugar content, and far red light sensitivity. The gene is also connected to phenotypes such as dwarfism, root development, stress tolerance, and longevity.
