Source Description
TAIREncodes LEC1-Like (L1L), closely related to LEC1 (Leafy Cotyledon1). Functions as a regulator of embryo development.
UniProtComponent of the NF-Y/HAP transcription factor complex. The NF-Y complex stimulates the transcription of various genes by recognizing and binding to a CCAAT motif in promoters. Plays a role in the regulation of the embryogenesis. Involved in the abscisic acid (ABA) signaling pathway. {ECO:0000269|PubMed:12509518, ECO:0000269|PubMed:17322342}.
Function -- GeneRIF ? help Back to Top
  1. LEC1 and LEC1-LIKE activate the CRUCIFERIN C and SUCROSE SYNTHASE 2 (SUS2) promoters in combination with an NF-YC subunit through the interaction with a seed-specific ABA-response element (ABRE) binding bZIP factor, bZIP67. [L1L] [LEC1-LIKE]
