Mutants of Maize by G. Neuffer, E. H. Coe and S. R. Wessler contains more than 400 colour photographs of the diverse genetic variants of corn. First published in 1968 and long out of print, it now covers twice the number of mutants and provides detailed descriptions of mutant gene loci as well as summaries of the physical structure of cloned genes. Mutant maize genes have counterparts in most higher plant species, so the book should have a wider readership than just corn biologists. Cold Spring Harbor Laboratory Press, $250 (hbk), $100 (pbk).
