Current understanding is largely derived from controlled laboratory studies, whereas field PHS is a multi-scale phenomenon resulting from interactions among genetic regulation, spike and grain traits, heterogeneous environmental conditions, and agronomic management. Our knowledge of PHS mechanisms under field conditions remains limited, and a systematic, integrated control framework is still lacking. In this review, we synthesise advances in the genetic architecture, physiological regulation, phenotypic determinants, and environmental factors of PHS in cereals, with emphasis on integrating multi-scale regulatory networks with environmental drivers. We particularly focus on laboratory-field discrepancies and how environmental heterogeneity influences grain quality deterioration and PHS outcomes under field conditions., and further evaluate current control strategies for PHS, including breeding, agronomic management, and chemical regulation, especially their limitations, environmental dependence, and associated trade-offs in practical application. Finally, we propose that future PHS control will require integrating field-relevant phenotypes, genotype × environment × management interactions, multi-scale predictive modelling, and decision-support systems to improve field-level resilience to PHS under increasingly variable climatic conditions.</p>","PeriodicalId":222,"journal":{"name":"Plant, Cell & Environment","volume":" ","pages":"9770-9787"},"PeriodicalIF":6.9,"publicationDate":"2026-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148862849","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, it is also prone to waterlogging damage. Therefore, understanding its response to waterlogging is crucial for breeding waterlogging-tolerant varieties. Although Rho of Plants GTPases play well-established roles in regulating development and stress signalling, their functions in plant adaptation to waterlogging stress has yet to be fully elucidated. Here, we identified nine CsROP genes in the cucumber genome, which exhibit evolutionary diversification but retain conserved functional domains. Functional analysis revealed that CsROP2 acts as a negative regulator of adventitious root formation. It modulates auxin accumulation in hypocotyl vascular bundles, thereby suppressing adventitious root development and enhancing waterlogging sensitivity. The HD-Zip I transcription factor CsTBH directly binds the CsROP2 promoter and activates its expression. Our study uncovers a CsTBH-CsROP2 module that governs adventitious rooting and waterlogging tolerance by modulating auxin homeostasis.

The Cf gene confers resistance to C. fulvum. In our previous study, several JAZ family genes were found to be differentially expressed between resistant (Cf-19-mediated) and susceptible materials, especially SlJAZ3, whose expression was significantly upregulated during the Cf-19-mediated resistance response process. To explore the regulatory function of JAZ genes in this disease resistance system, this study focused on SlJAZ3 and found that both SlJAZ3 and its interacting protein SlJAZ2 can positively regulate the resistance response mediated by Cf-19. In addition, SlMYC2, as a positive regulator of the resistance response, can interact with SlJAZ2 (or SlJAZ3) and activate the expression of SlPR2. Notably, SlJAZ3 (or SlJAZ2) competitively binds to SlJAZ2 (or SlJAZ3), reducing its binding to SlMYC2, which helps to restore the transcriptional activation of the downstream defense gene SlPR2. Our findings reveal that the SlJAZ2/SlJAZ3 dimer regulates downstream signal transduction.

While the effects of elevated CO₂ on photosynthesis and vegetative biomass have been extensively studied, its direct impact on male reproductive development remains poorly understood. Here, we show that elevated CO₂ improves pollen vigour and performance in tomato (Solanum lycopersicum). Through genetic and molecular analyses, we identify β-type carbonic anhydrase 2 (βCA2) as a pollen-enriched CO₂ sensor required for this response. Loss of βCA2 abolishes the promoting effects of elevated CO₂ on fertility, whereas βCA2 overexpression mimics the high-CO₂ phenotype under ambient conditions. Further analyses revealed that βCA2 regulates downstream networks involved in vesicle trafficking and intracellular transport to promote pollen germination, alongside cellulose and pectin metabolism required for pollen intine remodelling. These findings suggest a potential link between βCA2-mediated CO₂ perception, intracellular transport and pollen intine remodelling.

Here, we reported a member of 9-cis-epoxycarotenoid dioxygenase family (NCED), OsNCED5, which regulates proper anther dehiscence for male fertility in rice. OsNCED5 encodes a chloroplast-localized ABA biosynthetic enzyme highly expressed in anther during the late phase. Disruption of OsNCED5 by CRISPR/Cas9-mediated mutagenesis led to the reduction of ABA accumulation in anthers, thus the failure of secondary cell wall (SCW) thickening in anther endothecium due to loss of lignin biosynthesis, which eventually resulting in indehiscent anthers and significantly reduced fertility. Further analysis indicated that OsNCED5 probably confer a conserved fertility regulation mechanism between japonica and indica subspecies.

However, how plants prioritize the activation of pathways to balance disease resistance with drought and salt tolerance remains unclear. Here, we identify two regulatory modules centered on the rice protein OsSRLD, which negatively regulates disease resistance and positively regulates drought/salt tolerance. Upregulation of OsSRLD increases ABA content and reduces ROS levels under both normal and stressed conditions, suggesting its involvement in ABA signaling and ROS homeostasis. As an E3 ligase, OsSRLD interacts with OsIMα1a (a positive regulator of disease resistance) and promotes its ubiquitination and degradation via the 26S proteasome. Additionally, OsIMα1a interacts with OsWRKY53 (a positive regulator of disease resistance but a negative regulator of salt tolerance), thereby promoting the nuclear accumulation of OsWRKY53. Consistently, both overexpression of OsSRLD and knockout of OsIMα1a resulted in downregulation of OsWRKY53-activated genes and upregulation of OsWRKY53-inactivated genes. Furthermore, OsSRLD interacts with and stabilizes OsDIP1 (a positive regulator of drought and salt tolerance) via an E3 ligase-independent pathway.
