Arabidopsis Jasmonate Signaling Pathway

摘要: Jasmonates control defense gene expression and male fertility in the model plant Arabidopsis thaliana. In both cases, involvement of jasmonate pathway is complex, involving large-scale transcriptional reprogramming. Additionally, signaling hard-wired into auxin, ethylene, salicylate signal networks, all which are under intense investigation Arabidopsis. fertility, jasmonic acid (JA) essential intervening at level anther elongation pollen dehiscense. A number genes potentially involved jasmonate-dependent have recently been discovered. case defense, least two jasmonates, JA its precursor 12-oxo-phytodienoic (OPDA), necessary for fine-tuning response to various microbial pathogens arthropod herbivores. However, only OPDA required full resistance some insects fungi. Other jasmonates probably affect yet more physiological responses. series breakthroughs identified SKP/CULLIN/F-BOX (SCF), CORONATINE INSENSITIVE (COI1) acting together with CONSTITUTIVE PHOTOMORPHOGENIC 9 (COP9) signalosome, as central regulatory components The studies, mostly mutational approaches, paved way suppressor screens that expected further extend our knowledge signaling. When these other new mutants affecting characterized, nodes will be added Jasmonate Signaling Pathway Connections Map, lists target regulated by expanded.
