Insect elicitors and exposure to green leafy volatiles differentially upregulate major octadecanoids and transcripts of 12-oxo phytodienoic acid reductases in Zea mays.

摘要: The induction of jasmonic acid (JA) is one the major signaling events in plants response to insect herbivore damage and leads activation direct indirect defensive measures. Green leafy volatiles, which constitute a portion volatile organic compounds, often are released attack have been shown significantly activate JA production exposed corn (Zea mays) seedlings, thereby priming these specifically against subsequent attack. To explore factors determining specificity octadecanoid pathway corn, we analyzed qualitative quantitative changes octadecanoids. time course amount induced 12-oxophytodienoic levels seedlings were strikingly different after wounding, application caterpillar regurgitant, or treatment with cis-3-hexenyl acetate (Z-3-6:AC). Exposure Z-3-6:AC accumulation transcripts encoded by three putative 12-oxophytodienoate...
