[Starch synthesis in the maize endosperm as affected by starch-synthesizing mutants]. [Annual report, March 1994--June 30, 1995]

PDF Version Also Available for Download.

Description

Progress is reported in several areas relevant to maize endosperm development. These areas are (1) The tentative identification of the enzymatic deficiency in a previously unknown endosperm mutant, sugary3-1 (su3-1). The evidence leading to this conclusion will be presented below. (2) The recognition that the endosperm mutant that produces an interesting starch resembling some starches that have been chemically modified is actually an unusual, hypomorphic allele (8132) at the brittle2 (bt2) locus; (3) The orange endosperm color present in some progenies derived from a cross between the original bt2-8132 and W22N apparently results from an interaction between two genes, one ... continued below

In the orange endosperm derivative, our limited evidence suggests that the quantity of all the carotinoids present in the yellow endosperm stocks appear to be increased proportionally.
