NO-APICAL MERISTEM PROTEINS, POLYNUCLEOTIDES AND METHODS OF USE FOR SAME |
摘要 |
The present invention provides polynucleotides and related polypeptides of t he protein ZMNAM isolated from maize endosperm. The invention provides genomic sequence for the ZMNAM gene. ZMNAM is a novel gene and is regulated by gene- specific imprinting. ZMNAM expression is endosperm-specific and expressed throughout the endosperm development, peaking at 25DAP. Genomic imprinting h as been implicated to play a role in endosperm development. Genes regulated by allele-specific imprinting are suspected to be non-essential to seed development. Gene-specific imprinting however, regulates developmentally important genes. The ZMNAM gene, a putative transcriptional factor, may play an important role in endosperm development, which may further affect kernel size, plant vigor during germination and at the early seedling stage.</SDOAB >
