Annotated Information

Gene Symbol

• Os03g0174900 <=> OsNF-YA1

Function

• Nuclear factor Y (NF-Y) is a ubiquitous transcription factor that regulates important physiological and developmental processes.
• In plants, the roles of NF-Y were identified in regulation of embryogenesis, flowering time, chloroplast biogenesis, seed germination and stress tolerance

Expression

• Expression profile analysis covering the whole life cycle revealed that transcripts of OsNF-Y differentially accumulated in a tissue-specific preferential or constitutive manner.
• Analysis of expression correlation and Gene Ontology annotation suggested that OsNF-Y genes were co-expressed with genes that participated in stress, accumulation of seed storage reserves, and plant development.
• Co-expression analysis also revealed that OsNF-Y genes might interact with each other, suggesting that NF-Y subunits formed complexes that take part in transcriptional regulation.

Evolution

• NF-Y is a heterotrimeric complex composed of three subunits: NF-YA (CBF-B/HAP2), NF-YB (CBF-A/HAP3), and NF-YC

(CBF-C/HAP5).

• NF-Y complexes are CCAAT-specific transcription factors that bind to CCAAT sites in DNA to control the

expression of target genes
