β¦ Synopsis
The genetic control of NADH dehydrogenase-1 (NDH-1) and aromatic alcohol dehydrogenase-2 (AADH-2) was investigated in Triticum aestivum cv. Chinese Spring. Evidence was obtained that NDH-1 is active as a monomer and is encoded by genes located in the p arms of the homoeologous group 4 chromosomes. The NDH-1 gene loci located in 4Ap, 4Bp, and 4Dp were designated Ndh-A1, Ndh-B1, and Ndh-D1, respectively. Aadh-A2 was previously reported to be located in 6Aq; in this study, Aadh-B2 and Aadh-D2 were localized in 6Bq and 6Dq, respectively. Alcohol dehydrogenase-1 is expressed on AADH-2 zymograms; the presence of a contaminating aliphatic alcohol in one or more reagents is suggested as the probable cause of this phenomenon.

## Abstract ## BACKGROUND. It is believed that acetaldehyde plays an important role in alcoholβrelated carcinogenesis; although current epidemiologic studies have provided inconsistent findings on the association between alcohol consumption and the risk of lung cancer. ## METHODS. To clarify the
