Dominant amylose-extender mutant of maize

A transferrable maize gene is disclosed which is a dominant mutant allele at the amylose-extender (ae) locus. Maize seeds having this gene produce a high-amylose starch

Maize opaque5 Encodes Monogalactosyldiacylglycerol Synthase and Specifically Affects Galactolipids Necessary for Amyloplast and Chloroplast Function[C][W][OA]

The maize gene opaque5 encodes a monogalactosyldiacylglycerol synthase. Mutant analysis reveals that galactolipids with five double bonds are needed for thylakoid membrane function and cannot be substituted by the prevalent species with six double bonds. Galactolipid reduction results in altered starch granules, indicating a connection between amyloplast membranes and starch biosynthesis
