AFO — Lactuca sativa

Summary

LsAFO (AFO, YAB1, YAB2, YAB5, FIL) on chromosome 5 of garden lettuce (Lactuca sativa) encodes a YABBY family protein with DNA-binding, zinc-binding and protein-binding activities, localised to the nucleus. The gene is associated with the specification of organ position, floral organ identity, carpel and style development, adaxial/abaxial axis polarity, leaf and inflorescence meristem development, anther development, and cytokinin breakdown. It is linked to traits including leaf angle, leaf morphology, flowering time, anther morphology, pollen fertility restoration, sporogenesis, and microsporocyte development. Phenotypic associations include leaf patterning, phyllotaxis, adaxial-abaxial polarity, meristem formation, stamen architecture, and fruit ripening. Related genes in other species are linked to disease resistance, viral resistance, drought tolerance, cadmium tolerance, heat stress memory, and fruit and inflorescence development traits.
