- Oh E, Yamaguchi S, Hu J, Yusuke J, Jung B, Paik I, et al. PIL5, a phytochrome-interacting bHLH protein, regulates gibberellin responsiveness by binding directly to the GAI and RGA promoters in Arabidopsis seeds. Plant Cell. 2007;19:1192-208 pubmed..basic helix-loop-helix protein, inhibits seed germination by repressing GIBBERELLIN 3beta-HYDROXYLASE1 (GA3ox1) and GA3ox2 and activating a gibberellic acid (GA) catabolic gene (GA2ox2)...
- Kim Y, Nakajima M, Nakayama A, Yamaguchi I. Contribution of gibberellins to the formation of Arabidopsis seed coat through starch degradation. Plant Cell Physiol. 2005;46:1317-25 pubmed..These results strongly suggest that gibberellins in the outer integument would be required for the normal formation of the Arabidopsis seed coat. ..
- Matsushita A, Furumoto T, Ishida S, Takahashi Y. AGF1, an AT-hook protein, is necessary for the negative feedback of AtGA3ox1 encoding GA 3-oxidase. Plant Physiol. 2007;143:1152-62 pubmed..Here, we found that only the AtGA3ox1 among the AtGA3ox family of Arabidopsis (Arabidopsis thaliana) is under the regulation of GA-negative feedback...
- Zentella R, Zhang Z, Park M, Thomas S, Endo A, Murase K, et al. Global analysis of della direct targets in early gibberellin signaling in Arabidopsis. Plant Cell. 2007;19:3037-57 pubmed..In addition, one of the putative DELLA targets, XERICO, promotes accumulation of abscisic acid (ABA) that antagonizes GA effects. Therefore, DELLA may restrict GA-promoted processes by modulating both GA and ABA pathways. ..
