Hormone crosstalk in plant disease and defense: more than just jasmonate-salicylate antagonism. (2011, background): “(75) demonstrated that DELLAs physically interact with JAZ proteins, preventing AtMYC2 repression and consequently activating JA signaling.”
Plant hormone jasmonate prioritizes defense over growth by interfering with gibberellin signaling cascade (2012, background): “(23), under our experimental conditions, the della quintuple mutant (gai-t6/rga-t2/rgl1-1/rgl2-1/rgl3-1) was almost completely insensitive to JA-induced hypocotyl inhibition (Fig.”
Hormonal modulation of plant immunity. (2012, background): “Interestingly, DELLA proteins sequester the JA signaling repressor JAZ1 by binding to it, thereby reducing JAZ/MYC2 interactions and allowing MYC2 to activate JA-responsive target genes (Hou et al. 2010).”
Arabidopsis MYC2 Interacts with DELLA Proteins in Regulating Sesquiterpene Synthase Gene Expression[W][OA] (2012, background): “Notably, the investigation reported by Hou et al. (2010) focused on JA-responsive genes, whereas the sesquiterpene synthase genes we investigated here responded positively to both GA and JA signals.”
Plant hormone-mediated regulation of stress responses (2016, background): “Studies have shown that the DELLAs can interact with JAZ1, the key repressors of JA signaling, thus preventing JAZ1-mediated repression of transcription [95].”
Jasmonates: biosynthesis, metabolism, and signaling by proteins activating and repressing transcription (2016, background): “ 3) (Hou et al., 2010).”
Aspergillus niger CSR3 regulates plant endogenous hormones and secondary metabolites by producing gibberellins and indoleacetic acid (2018, background): “…CSR3 application. important for growth-promoting potential of CSR3 because JA antagonizes the positive effect of GA in many of plant growth aspects (Hou et al. 2010; Yang et al. 2012; Hou et al. 2013) To evaluate the growth-promoting effect of CSR3 as a GA and IAA producer, its impact was studied…”
Role of phytohormones in insect-specific plant reactions (2012, background): “Remarkably, GAs affect JA signaling through competitive binding of DELLAs to the JAZ proteins, thereby preventing JAZ–MYC2 interaction and promoting MYC2-induced transcriptional responses [89].”
Jasmonate Biosynthesis, Perception and Function in Plant Development and Stress Responses (2013, background): “GA triggers degradation of DELLAs, which releases free JAZ1 to bind to MYC2 and, thus, attenuates JA signaling (Hou et al., 2010).”
The role of gibberellin signalling in plant responses to abiotic stress (2014, background): “As such, the DELLA–JAZ interaction modulates both JA- and DELLA-mediated responses (Hou et al., 2010; Yang et al., 2012).”
The JAZ Proteins: A Crucial Interface in the Jasmonate Signaling Cascade (2011, background): “A remarkable finding has been that the DELLA proteins GIBBERELLIC ACID INSENSITIVE (GAI; At1g14920), REPRESSOR OF GA (RGA; At2g01570), and RGA-LIKE1 (RGL1; At1g66350) could also interact with JAZ proteins and compete with MYC2 for JAZ binding (Hou et al., 2010).”
Gibberellin signaling in plants (2013, background): “Through these interactions, DELLAs block the DNAbinding capacity of transcription factors (such as with PIFs) (de Lucas et al., 2008; Feng et al., 2008) or inhibit the activity of transcriptional regulators (such as with JAZs) (Hou et al., 2010).”
