Comparisons of LIPOXYGENASE3- and JASMONATE-RESISTANT4/6-silenced plants reveal that jasmonic acid and jasmonic acid-amino acid conjugates play different roles in herbivore resistance of Nicotiana attenuata.
Whereas jasmonic acid (JA) and its amino acid conjugates, particularly JA-isoleucine (Ile), are known to play important roles in plant-herbivore interactions, whether other compounds also function as signals independently of JA-Ile and whether conjugates elicit systemic responses are unknown. To answer these questions, we simultaneously silenced JASMONATE-RESISTANT4 (JAR4) and JAR6, two functio...
متن کاملOxygen-evolving activity of thylakoids from barley plants cultivated on different concentrations of jasmonic Acid.
The kinetics characteristics of oxygen evolution in thylakoids prepared from barley (Horeum vulgare) seedlings grown in the presence of different jasmonic acid (JA) concentrations were studied. In comparison to control preparations, 100 micromolar JA-treated samples show an inhibition of the Hill activity (46%) and of O(2)-flash yields to above 70%. A damping in the oscillations of O(2) yields,...
متن کاملThe arabidopsis DELAYED DEHISCENCE1 gene encodes an enzyme in the jasmonic acid synthesis pathway.
delayed dehiscence1 is an Arabidopsis T-DNA mutant in which anthers release pollen grains too late for pollination to occur. The delayed dehiscence1 defect is caused by a delay in the stomium degeneration program. The gene disrupted in delayed dehiscence1 encodes 12-oxophytodienoate reductase, an enzyme in the jasmonic acid biosynthesis pathway. We rescued the mutant phenotype by exogenous appl...
متن کاملSignaling in the elicitation process is mediated through the octadecanoid pathway leading to jasmonic acid.
Fungal cell walls and fragments thereof (elicitors) induce the formation of low and high molecular weight defense compounds in plant cell suspension cultures. This induced synthesis requires a signal molecule transmitting the message between the elicitor plant cell wall receptor and gene activation. We demonstrate in this study that cis-jasmonic acid is rapidly synthesized in plant cell culture...
متن کاملJasmonic Acid: Genetic Pathway, Signal Transduction and Action in Plant Development and Defence
Jasmonic acid (JA) is one of the most signaling phytohormones which play an essential role in plant development and response to biotic and abiotic stresses. It plays a key regulatory role in root elongation, pollen production, germination, fruit ripening, plant senescence [1]. Additionally, it activates plant defenses against pests, pathogens and abiotic stress. Jasmonic acid and its derivative...
