Description Electrophoretic mobility; null alleles are known; dimeric; intra/interlocus hybrid bands occur); SSR umc1726. Encodes a dimeric enzyme (ADH1; E.C. 1.1.1.1) involved in the terminal step of ethanolic fermentation. Intra/interlocus hybrid dimers occur (Schwartz 1966 PNAS 56:1431)--see also adh2. Natural variations found in electrophoretic mobility (slow, fast, superfast allozymes encoded by Adh1-S, -F, and -C alleles, Schwartz and Endo 1966 Genetics 53:709). Variations found in enzyme-specific activity (-Cm allele has 5% normal activity, Schwartz and Endo 1966). Null allele found in IL14H (Stuber and Goodman 1983 Ag Res Results 16:1). Variations in organ specific expression with -1F, -33F, -1S, -54S (Woodman and Freeling 1981; Williams et al. 1991). Some allele pairs are incapable of intragenic recombination (-1S, -1F; Freeling 1976, 1978). A tightly linked duplication is known (-FCm; Schwartz and Endo 1966; Birchler and Schwartz 1979). Many mutants induced by EMS and transposable element insertion have been isolated (cf. Freeling and Birchler 1981 Genetic Engineering p. 223; Freeling and Bennett 1985 Ann. Rev. Genet. 19:297). Molecular clone (Gerlach et al. 1982). Nucleotide sequence of natural alleles (Dennis et al. 1984; Sachs et al. 1986; Osterman and Dennis 1989). Expressed at high levels in the prop root (Schwartz 1979), developing embryo and endosperm (Russell and Sachs 1991), and post-meiotic microspore (Schwartz 1971; Freeling 1976), and anaerobically inducible in root and pre-emergent seedling shoot (cf. Sachs 1991). Not expressed in post-emergent leaf (Okimoto et al. 1980). Regulated by dosage of a factor located elsewhere on chromosome 1L (Birchler 1981). ADH1 null seeds and seedlings are very sensitive to flooding anoxia (Schwartz 1969; Lemke-Keyes and Sachs 1989). Selection against activity in pollen by exposure to allyl alcohol (Schwartz and Osterman 1976). (M. Sachs). bnl(adh1)(pH2.3), npi21(adh1), umc(adh1). Expression (using gel electrophoresis of extract followed by ADH specific staining): kernel (scutellum or aleurone) excellent; seedling (root flooded 24h) excellent; plant (flooded root) very good; pericarp not detected; prop root excellent; pollen very good (to distinguish ADH+ from ADH- one can also use in situ staining of pollen). Viability of ADH1 null plant is good to very good (except under flooding or other low oxygen conditions; i.e. conditional lethal). Primary root tips are very sensitive to anoxia. Induction by anoxia, in the primary root tip, is small and transient relative to induction by hypoxia unless there is a hypoxic pretreatment. This pretreatment allows the root tip to survive anoxia about as long as the more proximal parts of the root can without the hypoxic pretreatment. PCO141653_ov hits 5 BACs, of which 4 are in the same contig as of 28 Sep 05. PCO141653_ov is from AY104325, matched by TIGR to adh1. This gene was originally curated in MaizeGDB Database and the map position was displayed on the maize bins map if feasible.
