Cyclopentenone signals for plant defense: Remodeling the jasmonic acid response

The AP2/ERF domain transcription factor ORA59 integrates jasmonic acid and ethylene signals in plant defense.

Plant defense against pathogens depends on the action of several endogenously produced hormones, including jasmonic acid (JA) and ethylene. In certain defense responses, JA and ethylene signaling pathways synergize to activate a specific set of defense genes. Here, we describe the role of the Arabidopsis (Arabidopsis thaliana) APETALA2/ETHYLENE RESPONSE FACTOR (AP2/ERF) domain transcription fac...

Defense Induced by Jasmonic Acid: A Review

Plants are very delicate have no opportunity other than to adapt their growth and changing with environment and need to coordinate their growth and physiology responses. Plants present in an environment in ancient time characterized by the presence of various types of stresses both biotic and abiotic. Phytohormones play important role in plant growth, development and response to stresses. Plant...

Aloe Striata Plant Defense Compounds Produced in Response to Jasmonic Acid, Salicylic Acid, and Eriophyid Mite Salivary Extract Elicitor Compounds

Integrating nitric oxide into salicylic acid and jasmonic acid/ ethylene plant defense pathways

Plant defense against pests and pathogens is known to be conferred by either salicylic acid (SA) or jasmonic acid (JA)/ethylene (ET) pathways, depending on infection or herbivore-grazing strategy. It is well attested that SA and JA/ET pathways are mutually antagonistic allowing defense responses to be tailored to particular biotic stresses. Nitric oxide (NO) has emerged as a major signal influe...

Suppression of Jasmonic Acid-Dependent Defense in Cotton Plant by the Mealybug Phenacoccus solenopsis

The solenopsis mealybug, Phenacoccus solenopsis, has been recently recognized as an aggressively invasive pest in China, and is now becoming a serious threat to the cotton industry in the country. Thus, it is necessary to investigate the molecular mechanisms employed by cotton for defending against P. solenopsis before the pest populations reach epidemic levels. Here, we examined the effects of...
