Jiang K, Pi Y, Hou R, Zeng H, Huang Z, Zhang Z, Sun X, Tang K: Molecular cloning and expression profiling of the first specific jasmonate biosynthetic pathway gene allene oxide synthase from Lonicera japonica. Mol Biol Rep. 2009 Mar;36(3):487-93. Epub 2008 Jan 1.
In jasmonate biosynthetic pathway, allene oxide synthase (AOS, EC 4.2.1.92), which is a cytochrome P450 (CYP74A), catalyzes the first committed step. We herein cloned a novel cDNA from Lonicera japonica Thunb., named LjAOS (GenBank accession: DQ303120), which was homologous to other AOSs. Southern blot analysis revealed that it was a multi-copy gene. Real-time quantitative PCR analysis showed that LjAOS mRNA accumulated most abundantly in alabastrums, in which the content of chlorogenic acid (CA, the major important active ingredient indicator) was previously proven to be the highest. |
