Appears in the following schemes


Protein function

Encodes a subunit of a CCAAT-binding transcriptional factor.

Phenotype

Remarks:
LEC1 is highly expressed in the young embryo and is known to be involved in plant development. [Meinke et al., 1994][West et al., 1994][Lee et al., 2003][Lotan et al., 1998]

Single mutant:
lec1 single mutant shows several developmental defects during the embryo development. [Meinke et al., 1994][Meinke et al., 1992][Parcy et al., 1997]

Remarks:
LEC1, L1L, NFYC2, and bZIP67 interact to promote the expression of ABA-responsive genes. [Yamamoto et al., 2009]

Function:
Component 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. Acts as a central regulator of the embryogenesis. Required for the speciation of cotyledon identity and the completion of embryo maturation. Controls seed storage protein genes through the regulation of FUS3 and ABI3. Involved in the blue light (BL) and abscisic acid (ABA) signaling pathways. [Data from UniProt]
