Three Adh-1 genes have been identified in Hordeum vulgare and H. spontaneum (562, 704, 705, 706). Two of these are tightly linked at the Adh-H1 locus (704). The third gene was tentatively located in 5H (706). The gene series formerly designated Adh-2 and Adh-3 now appear under Aromatic alcohol dehydrogenase.
In S. cereale, in addition to Est-R1, genes encoding leaf esterases have been located in three chromosomes (701). These include a gene designated Est8 in 6R in cvs. lmperial and King II, a gene designated Est2 and two genes, designated Est6 and Est7, which are part of a separate compound locus (722), in 5RL in Imperial, and a gene designated Est10 in 4R of King II and 4RL of Imperial. In Hordeum vulgare, genes encoding leaf esterases have been located in 3H (707, see also 708, 562), and 7H (562).
