Hn. Truong et al., SEQUENCE AND CHARACTERIZATION OF 2 ARABIDOPSIS-THALIANA CDNAS ISOLATED BY FUNCTIONAL COMPLEMENTATION OF A YEAST GLN3 GDH1 MUTANT, FEBS letters, 410(2-3), 1997, pp. 213-218
We have isolated two Arabidopsis thaliana cDNAs by complementation of
a yeast gln3 gdh1 strain that is affected in the regulation of nitroge
n metabolism, The two clones (RGA1 and RGA2) are homologous to each ot
her and to the SCARE-CROW(SCR) gene that is involved in regulating an
asymmetric cell division in plants, RGA1, RGA2 and SCR share several s
tructural features and may define a nem family of genes, RGA1 and RGA2
have been mapped, respectively, to chromosome II and I, and their exp
ression in plant is constitutive. (C) 1997 Federation of European Bioc
