Description | Senescence begins at least 2 weeks prior to anthesis, spreading from bottom to top of plant; occasionally sheds viable pollen. Senescence begins at least 2 weeks prior to anthesis. Chlorosis and necrosis begin at the tip and margins of the leaves and spread toward the leaf base. Senescence is first seen in the lowermost leaves and spreads to the top of the plant. Plants are fully chlorotic and necrotic within 2 weeks after anthesis. Wild-type sectors are occasionally observed in senescent tissue. Male-sterility is associated with the mutation but occasionally plants shed viable pollen. (S. Briggs). In B73 background, can be maintained in homozygous condition; phenotype almost disappears if br2 is also in the background. This gene was originally curated in MaizeGDB Database and the map position was displayed on the maize bins map if feasible. |
