AP1C — Lactuca sativa

Summary

LsAP1C, also known as AP1C, is a MADS-box transcription factor on chromosome 7 of garden lettuce. It encodes a protein with a MADS-box and K-box domain that binds DNA and regulates transcription. The gene is associated with the specification of floral organ and carpel identity, stamen formation, floral meristem maintenance, and seed growth. It is linked to the regulation of vernalization response, photomorphogenesis, and meristem development. Associations with agronomic traits include days to flowering, photoperiod-sensitive flowering time, inflorescence and flower morphology, petal number, root length, anthocyanin content, photosynthetic rate, and responses to high temperature, UV light, and cytokinin. The gene is also linked to drought tolerance, cold tolerance, leaf senescence, and stomatal behaviour.
