| 1 | Arabidopsis RAV1 is down-regulated by brassinosteroid and may act as a negative regulator during plant development显示文摘RAV1 is a novel DNA-binding protein with two distinct DNA-binding domains unique in higher plants,but its role in plant growth and development remains unknown. Using cDNA array,we found that transcription of RAV1 is downregulated by epibrassinolide (epiBL) in Arabidopsis suspension cells. RNA gel blot analysis revealed that epiBL-regulated RAV1 transcription involves neither protein phosphorylation/dephosphorylation nor newly synthesized protein,and does not require the functional BRI1,suggesting that this regulation might be through a new BR signaling pathway.Overexpressing RAV1 in Arabidopsis results in a retardation of lateral root and rosette leaf development,and the underexpression causes an earlier flowering phenotype,implying that RAV1 may function as a negative regulatory component of growth and development. | YuXinHU YongHongWANG XinFangLIU JiaYangLI | 2004 | Cell Research2004，14，1： | 53 |

| 3 | Arabidopsis Indole Synthase, a Homolog of Tryptophan Synthase Alpha, is an Enzyme Involved in the Trp-independent Indole-containing Metabolite Biosynthesis显示文摘The plant tryptophan (Trp) biosynthetic pathway produces many secondary metabolites with diverse functions. Indole- 3-acetic acid (IAA), proposed as a derivative from Trp or its precursors, plays an essential role in plant growth and development. Although the Trp-dependant and Trp-independent IAA biosynthetic pathways have been proposed, the enzymes, reactions and regulatory mechanisms are largely unknown. In Arabidopsis, indole-3-glycerol phosphate (IGP) is suggested to serve as a branchpoint component in the Trp-independent IAA biosynthesis. To address whether other enzymes in addition to Trp synthase α (TSA1) catalyze IGP cleavage, we identified and characterized an indole synthase (INS) gene, a homolog of TSA1 in Arabidopsis. INS exhibits different subcellular localization from TSA1 owing to the lack of chloroplast transit peptide (cTP). In silico data show that the expression levels of INS and TSA1 in all examined organs are quite different. Histochemical staining of INS promoter-GUS transgenic lines indicates that INS is expressed in vascular tissue of cotyledons, hypocotyls, roots and rosette leaves as well as in flowers and siliques. INS is capable of complementing the Trp auxotrophy of Escherichia coli trpA strain, which is defective in Trp synthesis due to the deletion of TSA. This implies that INS catalyzes the conversion of IGP to indole and may be involved in the biosynthesis of Trp-independent IAA or other secondary metabolites in Arabidopsis. | RuiZhang Bing Wang Jian Ouyang Jiayang Li YonghongWang | 2008 | Journal of Integrative Plant Biology2008，50，9： | 4 |
