maize mutant phenotypes

This is an old revision of the document!

shrunken inflated endosperm collapses on drying, forming smoothly indented opaque kernels.

shrunken selfed ear segregating for shrunken kernels; sucrose synthase-1 of endosperm. Note that dent corn tends to obscure sh1 expression.

shrunken Selfed ear segregating for brownish, pale "bronze" kernels; also slowing linkage of bz1 with sh1 in repulsion. Note bronze non-shrunken and purple shrunken crossovers.

shrunken multi-gene interaction: Selfed ear segregating for multiple aleurone and endosperm genes: pr1 (red/purple), R1 (solid anthocyanin/mottled/colorless), su1 (sugary/normal), y1 (white/yellow endosperm), sh1 (shrunken/normal kernel), and wx1 (waxy/normal), in an intense, in1, purple popcorn background. A demonstration of gene dosage, gene interaction, independent assortment, and linkage; phenotypes of seven genes clearly displayed all on one ear!
