DELLAs Control Plant Immune Responses by Modulating the Balance of Jasmonic Acid and Salicylic Acid Signaling
In Arabidopsis, the flagellin-derived peptide flg22 elevates antibacterial resistance [1] and inhibits growth [2] upon perception via the leucine-rich repeat receptor-like kinase Flagellin-Sensitive 2 (FLS2) [3]. DELLA proteins are plant growth repressors whose degradation is promoted by the phytohormone gibberellin [4]. Here, we show that DELLA stabilization contributes to flg22-induced growth...
متن کاملHow salicylic acid takes transcriptional control over jasmonic acid signaling
Transcriptional regulation is a central process in plant immunity. The induction or repression of defense genes is orchestrated by signaling networks that are directed by plant hormones of which salicylic acid (SA) and jasmonic acid (JA) are the major players. Extensive cross-communication between the hormone signaling pathways allows for fine tuning of transcriptional programs, determining res...
متن کاملH2O2 and in ensuring appropriate gene expression through both salicylic acid and jasmonic acid signaling pathways
GENOPLANTE programme " Redoxome ". Financial support of postgraduate students from the following sources is gratefully acknowledged: the Tunisian Ministry of Higher Education Abstract Glutathione is a major cellular thiol that is maintained in the reduced state by glutathione reductases (GR), which is encoded by two genes in Arabidopsis thaliana (GR1 and GR2). This study addressed the role of G...
متن کاملPlastidial fatty acid signaling modulates salicylic acid- and jasmonic acid-mediated defense pathways in the Arabidopsis ssi2 mutant.
A mutation in the Arabidopsis gene ssi2/fab2, which encodes stearoyl-acyl carrier protein desaturase (S-ACP-DES), results in the reduction of oleic acid (18:1) levels in the mutant plants and also leads to the constitutive activation of NPR1-dependent and -independent defense responses. By contrast, ssi2 plants are compromised in the induction of the jasmonic acid (JA)-responsive gene PDF1.2 an...
متن کاملWater Stress Responses of Tomato Mutants Impaired in Hormone Biosynthesis Reveal Abscisic Acid, Jasmonic Acid and Salicylic Acid Interactions
To investigate the putative crosstalk between JA and ABA in Solanum lycopersicum plants in response to drought, suppressor of prosystemin-mediated responses2 (spr2, JA-deficient) and flacca (flc, ABA-deficient) mutants together with the naphthalene/salicylate hydroxylase (NahG) transgenic (SA-deficient) line were used. Hormone profiling and gene expression of key enzymes in ABA, JA and SA biosy...
