We show that alternative splicing generates four isoforms with nonredundant roles. Full-length AGB1.1 resides at the plasma membrane and endoplasmic reticulum (ER), forms high-affinity dimers with all three Gγ subunits (AGG1-3) and completely rescues the developmental and abiotic-stress defects of agb1 null plants. AGB1.4, lacking part of the N-terminal coiled-coil, retains strong Gγ binding and affords partial rescue. By contrast, AGB1.2 and AGB1.3 show weak or transient Gγ interactions, reflecting missing coiled-coil/WD40 elements, and do not restore chronic-stress phenotypes. Nevertheless, each truncated variant confers niche advantages: AGB1.2 is rapidly induced by tunicamycin, accumulates in nuclei and mitigates early ER damage, whereas AGB1.3 associates with chloroplast margins and improves survival under moderate or delayed salinity stress. Collectively, the four isoforms expand potential Gβγ combinations from three to twelve, thereby diversifying plant G-protein outputs without gene family expansion. These findings provide a mechanistic framework whereby alternative splicing, rather than gene duplication, endows plants with flexible G-protein signaling modules to balance development and environmental resilience.</p>","PeriodicalId":222,"journal":{"name":"Plant, Cell & Environment","volume":" ","pages":""},"PeriodicalIF":6.3,"publicationDate":"2025-10-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145237469","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, the role and regulation of GSLs in environmental stress response remain ambiguous. Here, Methylthioalkylmalate synthase 1 (BolMAM1), a GSL biosynthesis-associated gene, was identified in broccoli. The overexpression of BolMAM1 enhanced both salt and drought tolerance in broccoli, along with an increase in aliphatic GSLs, such as 2(R)-hydroxy-3-butenyl GSL (progoitrin). Progoitrin could induce ABA accumulation in vitro. Consistently, ABA homoeostasis was modulated to accumulate more ABA in OEX-BolMAM1 transgenic broccoli. Moreover, sulforaphane (SFN), one of the hydrolysates of aliphatic GSLs, also exhibited accelerated accumulation in OEX-BolMAM1 transgenic broccoli. External application of SFN could rapidly induce stomatal closure. Furthermore, BolMYB28 was demonstrated to directly bind to the promoter of BolMAM1 and activate its transcription. These results indicated that BolMYB28-BolMAM1 confers tolerance to salt and drought stresses mainly by accelerating the biosynthesis of certain specific aliphatic GSLs. Progoitrin is a newly reported GSL positively regulating ABA accumulation. SFN may act as a signaling molecule to regulate stomatal behavior. These findings reveal the role of BolMYB28-BolMAM1 in abiotic stress response via regulating aliphatic GSL biosynthesis, and suggest the applications of progoitrin and SFN as natural defence factors to resist abiotic stresses in plants.</p>","PeriodicalId":222,"journal":{"name":"Plant, Cell & Environment","volume":" ","pages":""},"PeriodicalIF":6.3,"publicationDate":"2025-10-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145237426","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Maize silks, the essential tissues for pollen capture and pollen tube growth, are particularly sensitive to HT, are highly vulnerable to HT. Here, we combined phenotypic, physiological, metabolic and transcriptomic analyses under controlled HT (40/30°C) and control (32/22°C) conditions to dissect mechanisms underlying HT-induced silk growth inhibition (SGI) and silk pollination dysfunction (SPD). HT reduced silk emergence by ~20% but decreased seed set by ~50%, indicating SPD dominated kernel loss over SGI. HT significantly downregulated key genes of the silks that encode sucrose transporters, sugars will eventually be exported through transporters and glycolytic enzymes (hexokinase; 6-phosphofructokinase; pyruvate kinase), restricting energy metabolism required for silk elongation and pollen tube growth. Concurrently, HT elevated abscisic acid and indole-3-acetic acid while suppressing zeatin riboside, brassinolide and jasmonic acid levels, collectively driving SGI. SPD was primarily linked to oxidative damage via suppressed flavonoid biosynthesis (chalcone synthase, flavonol synthase and peroxidase) and impaired reactive oxygen species (ROS) scavenging. Specifically, HT induced a negative correlation between ZmARF1 and ZmSOD3 expression, suggesting compromised ROS clearance that exacerbated silk structural damage. These findings provide new insights into the metabolic, hormonal and transcriptional regulatory networks that govern silk thermotolerance, providing potential molecular targets for breeding heat-resilient maize varieties.</p>","PeriodicalId":222,"journal":{"name":"Plant, Cell & Environment","volume":" ","pages":""},"PeriodicalIF":6.3,"publicationDate":"2025-10-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145211222","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Further gibberellic acid (GA) treatment showed that exogenous GA can replace long-term chilling to promote BDT, likely by inhibiting the expression of PlOBP1 while inducing the expression of PlSOC1.

Plant-mediated RNA interference (RNAi) offers a target-specific and eco-friendly alternative for pest control. While RNAi has been shown to effectively control certain Coleoptera, its effects on piercing-sucking insects, such as R. pedestris, remain poorly understood. In this study, we characterized a non-ATPase regulatory subunit 6 (RPN6) from R. pedestris and demonstrated that downregulation of RPN6 expression significantly increased mortality and reduced oviposition. Phylogenetic analysis revealed that while RPN6 is highly conserved across Hemiptera, the double-stranded RNA (dsRNA) targeting RPN6 is species-specific. We subsequently developed dsRPN6-transgenic soybean lines, and feeding bioassays revealed these transgenic soybean lines exhibited high resistance to R. pedestris, with significantly reduced survival and oviposition rates in the pest.
