AP1C — Lactuca sativa

Summary

LsAP1C (AP1C) on chromosome 4 of garden lettuce encodes a protein with MADS-box and K-box domains. It is associated with DNA binding, RNA polymerase II transcription regulatory region sequence-specific DNA binding, transcription corepressor activity, and DNA-binding transcription factor activity. The gene is associated with the regulation of floral meristem identity, floral organ specification and morphogenesis, carpel and stamen development, seed growth, and the downregulation of vernalization response. It has been linked to numerous traits including flowering time, photoperiod sensitivity, flower and inflorescence morphology, petal and sepal number, chloroplast development, anthocyanin content, photosynthetic rate, root length, and responses to high temperature, UV light, cytokinin, and brassinosteroids. Studies of related genes in other species connect the family to floral induction, drought tolerance, cold tolerance, stomatal regulation, and autophagy.
