Abstract Extreme weather conditions associated with climate change affect many aspects of plant and animal life, including the response to infectious diseases. Production salicylic acid (SA), a central defence hormone 1–3 , is particularly vulnerable suppression by short periods hot above normal growth temperature range via an unknown mechanism 4–7 . Here we show that SA production in Arabidopsis thaliana at 28 °C independent PHYTOCHROME B 8,9 (phyB) EARLY FLOWERING 3 10 (ELF3), which...
Abstract Really Interesting New Gene (RING) E3 ubiquitin ligases have been implicated in cellular responses to the stress hormone abscisic acid (ABA) as well environmental stresses higher plants. Here, an ABA-insensitive RING protein3 (atairp3) loss-of-function mutant line Arabidopsis (Arabidopsis thaliana) was isolated due its hyposensitivity ABA during germination stage compared with wild-type AtAIRP3 contains a single C3HC4-type motif, putative myristoylation site, and domain associated...
AtAIRP2 is a cytosolic RING-type E3 ubiquitin ligase that positively regulates an abscisic acid (ABA) response in Arabidopsis (Arabidopsis thaliana). Yeast two-hybrid screening using as bait identified ATP1 (AtAIRP2 Target Protein1) substrate of AtAIRP2. was found to be identical SDIRIP1, which reported recently negative factor ABA signaling and target protein the RING SDIR1. Accordingly, renamed ATP1/SDIRIP1. A specific interaction between ATP1/SDIRIP1 ubiquitination by were demonstrated...
Controlled turnover of proteins as mediated by the ubiquitin proteasome system (UPS) is an important element in plant defense against environmental and pathogen stresses. E3 ligases play a central role subjecting to hydrolysis UPS. Recently, it has been demonstrated that specific class termed U-box are directly associated with mechanisms abiotic biotic stresses several plants. However, no studies on have performed one staple crops, barley. In this study, we identified 67 putative from barley...
SUMMARY Ubiquitination is a critical post‐translational protein modification that has been implicated in diverse cellular processes, including abiotic stress responses, plants. In the present study, we identified and characterized T‐DNA insertion mutant At5g10650 locus. Compared to wild‐type Arabidopsis plants, at5g10650 progeny were hyposensitive ABA at germination stage. possessed single C‐terminal C3HC4‐type Really Interesting New Gene (RING) motif, which was essential for ABA‐mediated E3...
Summary Oryza sativa BRASSINAZOLE RESISTANT 1 (Os BZR 1) is the closest rice homolog of Arabidopsis and bri1 ‐ EMS SUPPRESSOR ( BES 1)/ 2 transcription factors. Os plays a central role in brassinosteroid signaling pathway. Despite its functional importance, control mechanism by which cellular stability regulated has not yet been fully elucidated. Here, we report that U‐box E3 ubiquitin (Ub) ligase PUB 24 acts as negative regulator BR pathway via 26S proteasome‐dependent degradation 1. The...
Significance The essential roles of cytoplasmic E3 ligases in the protein quality control (PQC) pathways have been increasingly highlighted yeast and animal studies. However, plants, only CHIP ligase has characterized, while knowledge PQC remains rudimentary. Misfolded Protein Sensing RING 1 (MPSR1), a self-regulatory sensor system that functions occurrence misfolded proteins, is an identified plants directly recognizes emergent proteins independently chaperones. In addition, MPSR1 sustains...
Abstract Climate warming influences disease development by targeting critical components of the plant immune system, including pattern-triggered immunity (PTI), effector-triggered (ETI) and production central defence hormone salicylic acid (SA) at primary pathogen infection site. However, it is not clear if and/or how temperature impacts systemic immunity. Here we show that pathogen-triggered acquired resistance (SAR) in Arabidopsis thaliana suppressed elevated temperature. This was...
MISFOLDED PROTEIN SENSING RING1 (MPSR1) is a chaperone-independent E3 ubiquitin ligase that participates in protein quality control by eliminating misfolded proteins Arabidopsis (Arabidopsis thaliana). Here, we report the early stages of proteotoxic stress, cellular levels MPSR1 increased immediately, whereas HEAT SHOCK PROTEIN90.1 (AtHSP90.1) were unaltered despite massively upregulated transcription. At this stage, gene-silencing pathway mediated microRNA 414 (miR414) suppressed AtHSP90.1...
Summary Drought stress has detrimental effects on plants. Although the abscisic acid (ABA)‐mediated drought response is well established, defensive mechanisms to cope with dehydration‐induced proteotoxicity have been rarely studied. DRR1 was identified as an Arabidopsis drought‐induced gene encoding ER‐localized RING‐type E3 Ub ligase. Suppression of markedly reduced tolerance and proteotoxic without altering ABA‐mediated germination stomatal movement. Proteotoxicity‐ insoluble ubiquitinated...
SUMMARY ACCELERATED CELL DEATH 6 (ACD6) mediates a trade-off between growth and defense in Arabidopsis thaliana . However, the precise biochemical mechanism by which ACD6 related proteins plants act remains enigmatic. Here, we identified two loci, MODULATOR OF HYPERACTIVE 1 ( MHA1 ) its paralog MHA1-LIKE MHA1L ), that code for ∼7 kDa differentially interact with specific variants. enhances accumulation of an complex, thereby increasing activity standard allele regulating plant defenses. is...

Water-deficit affects nearly every biological event in plants, and recent studies have shown that microRNA-functionality is associated with plant responses to water-deficiency. Liquid-liquid phase separation facilitates the condensation of biomolecules, which driven by intrinsically disordered proteins plays diverse roles cellular processes. Here, we show prion-like domain (PrLD) ARGONAUTE 1 responsible for topological changes from liquid droplets solid-condensations AGO1 under dehydration....
