Abstract excerpt
In Arabidopsis, three receptors exist for the phytohormone gibberellin. Of the three, only a double loss-of-function mutant (atgid1a atgid1c) shows a dwarf phenotype, while other double and all single mutants show no abnormality in height. In this study we show that the expression of AtGID1b-GUS mRNA, driven by the AtGID1b promoter, is low in inflorescence stems, but may be 10% of AtGID1a-GUS mRNA, driven by the...
