A quick reference to the great diversity of mutant phenotypes expressed by the maize plant, with over 400 color photographs of well- established mutants arranged by chromosome position, detailed description of the mutants' gene loci, and a current summary of the physical structure of genes that have been characterized at the molecular level. Also covers the maize organism, tables and pathways, cloned genes, non-mutation effects, and mutagenesis. Deeply revised from the 1968 edition and enlarged to cover twice as many mutants. Of interest to maize biologists, other scientists studying the consequences of mutation elsewhere in the plant kingdom, and gardeners living on or near hazardous waste sites. Indexed by genes as well as by subjects. Annotation c. by Book News, Inc., Portland, Or.
