AP1C — Lactuca sativa

Summary

LsAP1C, also known as AP1C, encodes a K-box domain-containing transcription factor with DNA-binding transcription factor activity, RNA polymerase II-specific, and transcription corepressor activity. In garden lettuce (Lactuca sativa) on chromosome 4, this gene is associated with the regulation of flowering time, the transition from vegetative to reproductive phase, and the maintenance of inflorescence and floral meristem identity. It is linked to flower, sepal, petal, and stamen morphology traits, as well as photoperiod-sensitive flowering, days to flowering, and responses to gibberellin and jasmonic acid. Associations also include root length, leaf composition, anthocyanin content, photosynthetic rate, and responses to high temperature and UV-B light. Studies of related genes in other species connect the family to flowering time, floral organ identity, and stress responses including drought and cold tolerance.
