✦ Synopsis

Mutants Lacking

A quick iodine staining test was utilized to screen leaves for the capacity to accumulate starch from exogenously supplied glucose. Five maize mutants which had reduced capacities for starch accumulation were isolated from chlorophyll-deficient stocks. Quantitative starch determinations confirmed the visual test results. The mutants, 14, 17, 13, 1.4_92o, and wj 1, accumulated 3, 4, 18, 29, and 35 % of the starch of their respective normal sibs. These mutants are promising material for studies of enzymes responsible for starch biosynthesis and may prove useful for investigations of gene-plastid-enzyme relationships.

In corn seedlings (Zea mays L.) homozygous for the mutation gl5, the surface waxes are characteristically altered. In this mutant the main wax constituents (83.5%) are aldehydes while in the normal waxes alcohols predominate (62.7%). Moreover, in the normal waxes aldehydes and alcohols are made up m
