MAIZE SUGARY ENHANCER SEQUENCES

摘要

The sugary enhancer phenotype in maize results from the absence of expression of a nucleotide sequence located on Chromosome 2. Methods for screening, selecting or identifying plants containing the sequence and for estimating the sucrose content in maize plants are disclosed. Genetically modified plants having altered expression of the nucleotide sequence are provided.

主权项

1. A method of estimating the sucrose content in a maize plant, the method comprising;
performing an assay to detect the presence or absence of a polynucleotide encoding a polypeptide having at least 90% identity to SEQ ID NO: 4 or at least about 90% identity to SEQ ID NO: 5 in a sample from the plant;wherein detection of the sequence indicates low sucrose content in the maize plant, and wherein absence of the sequence indicates high levels of sucrose in the maize plant.
