Comment	Three subunits of the wheat tetrameric inhibitor of insect alpha-amylase, CM1, CM3 and CM16, with homology to the dimeric and monomeric alpha-amylase inhibitors and the trypsin inhibitors, were located by Southern analysis of cDNAs pCT1, pCT2 and pCT3 to 4A, 4B, 4D; 7A, 7B, 7D; and 4A, 4B, 4D, respectively (297). Genes encoding proteins which inhibit the action of mammalian and insect, but not cereal, alpha-amylases were located in chromosome- arms 3BS, 3DS and 6DS of Chinese Spring (890). Also, genes encoding inhibitors of insect alpha-amylases were located in H. chilense chromosomes 4H^ch^ and 7H^ch^ (892).
