Description | Small, somewhat defective kernel, fully viable; invertase reduced. Weight is 1/5 of normal. Earliest anatomical lesion is withdrawal of pedicel/placento-chalazal region from developing endosperm, loss of nutrients to developing seed and early cessation of growth. Abnormal development of maternal cells in the pedicel is determined by the genotype of the endosperm. Developing kernels of the mutant genotype show near complete loss (>99%) of invertase activity in both pedicel region and the endosperm (Miller and Chourey 1991 MNL65:62). (P.S. Chourey). This gene was originally curated in MaizeGDB Database and the map position was displayed on the maize bins map if feasible. |
