JAZ Repressors: Potential Involvement in Nutrients Deficiency Response in Rice and Chickpea
Jasmonates (JA) are well-known phytohormones which play important roles in plant development and defense against pathogens. Jasmonate ZIM domain (JAZ) proteins are plant-specific proteins and act as transcriptional repressors of JA-responsive genes. JA regulates both biotic and abiotic stress responses in plants; however, its role in nutrient deficiency responses is very elusive. Although, JA i...
متن کاملThe Responses of Physiological Stress during Table Tennis Competition in Elite Female Players
Stress is inevitable in competitive sports. Table tennis in the world known as a fastest ball game that requires attention and control stress. The main purpose of this study was investigation of physiological stress responses in elite table tennis players during competition. 16 female table tennis players (age average of 18.7 ± 3.8, height average of 161.6 ± 3.4 cm and weight aver...
متن کاملUnwinding JAZ7 – enigma to harmony
JASMONATE ZIM-DOMAIN (JAZ) proteins are primary transcriptional repressors in the jasmonate (JA) signal-ing pathway that regulate a broad range of JA-dependent responses. A mechanistic mode of action is well established , but what are the biological roles of individual JAZs, and how do they contribute to the specification of JA signaling outputs? Two recent articles in Journal of Experimental B...
متن کاملThe Arabidopsis bHLH transcription factors MYC3 and MYC4 are targets of JAZ repressors and act additively with MYC2 in the activation of jasmonate responses.
Jasmonates (JAs) trigger an important transcriptional reprogramming of plant cells to modulate both basal development and stress responses. In spite of the importance of transcriptional regulation, only one transcription factor (TF), the Arabidopsis thaliana basic helix-loop-helix MYC2, has been described so far as a direct target of JAZ repressors. By means of yeast two-hybrid screening and ta...
متن کاملComprehensive analysis of protein interactions between JAZ proteins and bHLH transcription factors that negatively regulate jasmonate signaling
Jasmonates have crucial roles in plant responses to biotic and abiotic stresses. Given the importance of transcriptional regulation in jasmonate-mediated stress responses, transcription factors are key regulators of jasmonate signaling. The transcription factors JASMONATE-ASSOCIATED MYC2-LIKE 1 (JAM1), JAM2, and JAM3 are negative regulators of jasmonate signaling, although the mechanisms that c...
