| 4.1.2.8 | indole-3-glycerol phosphate |
branch point from tryptophan biosynthesis, the enzyme is required for biosynthesis of 2,4-dihydroxy-7-methoxy-1,4-benzoxazin-3-one |
| 4.1.2.8 | indole-3-glycerol phosphate |
Igl transcript level is elevated by volicitin |
| 4.1.2.8 | indole-3-glycerol phosphate |
the indole-3-glycerol phosphate lyase Igl is the structural gene of volatile indole biosynthesis in the tritrophic interaction in maize. The gene is activated on transcriptional level with the same kinetics and to the same level by the fatty acid amino acid conjugates volicitin and N-linolenoyl-L-glutamine. Both conjugates are present in the regurgitates of herbivorous caterpillars. Modifications of the fatty acid moiety of the fatty acid amino acid conjugates greatly reduces the elicitation of Igl and only the L-stereoisomer of the fatty acid amino acid conjugates shows biological activity in the system. Volicitin treatment leads to a fast increase of allene oxide synthase and allene oxide cyclase transcription levels and methyl jasmonate application induces Igl transcription. Hence,the induction of jasmonate biosynthesis appears to be an integral part of the elicitor mediated increase of Igl gene transcription |
| 4.1.2.8 | indole-3-glycerol phosphate |
the indole is further converted to 2,4-dihydroxy-7-methoxy-2H-1,4-benzoxazin-3(4H)-one, a secondary plant metabolite. BX1 cleaves indole-3-glycerol phosphate significantly faster to indole and glyceraldehyde 3-phosphate than the homologous alpha-subunit of tryptophan synthase, EC 4.2.1.20 |
| 4.1.2.8 | more |
indole release activated by beet armyworm and methyl salicylate is preceded by igl gene (encoding indole-3-glycerol phosphate lyase) induction within 1.5 h of treatment and declines within 6 h, induction of the IGL gene expression is not observed with (Z)-3-hexenol treatment |
