{"title":"Screening of Wheat Varieties Under Combined Low Temperature and Waterlogging Stress Based on Physiological Phenotyping and Transcriptome","authors":"Tianhao Liu, Fasih Ullah Haider, Peng Zhang, Yang Gao, Feng Zhang, Chunsheng Zhao, Shuxin Li, Xiangnan Li","doi":"10.1111/jac.70194","DOIUrl":"https://doi.org/10.1111/jac.70194","url":null,"abstract":"Compound low‐temperature and waterlogging events frequently co‐occur during the wheat ( <jats:styled-content style=\"fixed-case\"> <jats:italic>Triticum aestivum</jats:italic> </jats:styled-content> L.) jointing stage. Still, cultivar ranking and the trait dimensions that discriminate tolerance under this compound stress remain poorly resolved because most studies consider each stress in isolation. Here, we screened 30 wheat cultivars under four treatments: normal water and temperature (NN), waterlogging at normal temperature (WN), normal water at low temperature (NL) and waterlogging at low temperature (WL). At jointing, potted plants were exposed outdoors in open‐top chambers (OTCs; day/night 15/−4°C) and/or waterlogging for 10 days, after which 26 physiological, biochemical and root anatomical indices were quantified (including chlorophyll fluorescence, relative electrical conductivity, TTC‐based root activity and root morphological traits) and yield components were determined at maturity. Integrating standardized indicators using principal component analysis, a membership function and clustering separated cultivars into four tolerance groups, identifying JM22 as highly tolerant and LY615 as highly sensitive. Across the panel, WL imposed the most potent inhibition of photosynthetic performance, root function and grain yield, exceeding the effects of WN or NL alone. Consistent with this ranking, JM22 maintained higher PSII efficiency and root activity under WL, accompanied by stronger induction of stress‐responsive, photosynthesis‐related gene sets. Root transcriptome analysis further indicated shared activation of phenylpropanoid biosynthesis in both cultivars, whereas differential regulation of plastid/photochemistry‐associated and nitrogen‐metabolism pathways distinguished tolerant versus sensitive responses. Together, these results provide a trait‐and‐transcript framework for identifying germplasm and prioritizing candidate processes for breeding and management in environments prone to concurrent cold and waterlogging.","PeriodicalId":14864,"journal":{"name":"Journal of Agronomy and Crop Science","volume":"26 1","pages":""},"PeriodicalIF":3.5,"publicationDate":"2026-04-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147752882","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Given the rapid warming rate, the extent to which cotton cultivation is exposed to heat, particularly during critical growth stages, remains uncharacterized. To settle this issue and propose potential adaptation measures, we evaluated the exposure of cotton cultivation to heat during the flowering and boll development stages in Xinjiang, and checked mitigation availability by changing the onset of flowering time. We employed extreme degree days (EDD, d·°C) and accumulated heat stress days (AHSD, d) to depict the spatiotemporal patterns of such exposure over the historical period (1961–2020) and two different warming scenarios (1.5°C and 2.0°C). The results revealed a modest upward trend of heat exposure during the critical growth stages, characterised by considerable interannual variability. Specifically, EDD and AHSD increased at 0.12 d·°C·a <jats:sup>−1</jats:sup> and 0.12 days·a <jats:sup>−1</jats:sup> , respectively. Despite notable spatial heterogeneity, regions such as Hami, Paotai, Yuli, and Mossel were identified as the most vulnerable, with EDD exceeding 25 d·°C and AHSD surpassing 9 days. Future projections suggest a substantial intensification of heat exposure, with EDD and AHSD values tripling and doubling under the 2.0°C warming scenario. Our findings highlight the critical importance of optimizing growth stage windows to reduce cotton's exposure to heat. Adaptive measures, such as adjusting planting windows and breeding new cultivars, are urgently needed to mitigate the negative climate impacts and ensure cotton productivity.","PeriodicalId":14864,"journal":{"name":"Journal of Agronomy and Crop Science","volume":"21 1","pages":""},"PeriodicalIF":3.5,"publicationDate":"2026-04-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147725596","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, the spatiotemporal distribution of soil moisture and its influence on ET <jats:sub>c</jats:sub> partitioning in drip‐irrigated maize fields are poorly understood. This study investigated soil water dynamics, leaf area index (LAI), ET <jats:sub>c</jats:sub> and its components under varying irrigation lower limits (W1: 50%–60% FC, W2: 65%–75% FC, W3: 80%–90% FC, where FC was the soil field capacity) during different maize growth stages in 2023 and 2024. The results indicated that as the irrigation amount increased, the vertical advance depth of the soil wetting front increased more significantly than the surface wetting radius Maize growth was suppressed at the tasselling stage under W1. T/ET <jats:sub>c</jats:sub> showed a quadratic relationship with ET <jats:sub>c</jats:sub> ( <jats:italic>R</jats:italic> <jats:sup>2</jats:sup> = 0.50) when reference evapotranspiration (ET <jats:sub>0</jats:sub> ) exceeded 1.9 mm d <jats:sup>−1</jats:sup> , with an inflexion point at ET <jats:sub>c</jats:sub> = 6.1 mm d <jats:sup>−1</jats:sup> . T/ET <jats:sub>c</jats:sub> correlated strongly with LAI through a logarithmic function ( <jats:italic>R</jats:italic> <jats:sup>2</jats:sup> = 0.95), especially at early growth stages. Soil water content (SWC) demand peaked at the tasselling stage. An irrigation strategy that maintains higher soil moisture (e.g., W3: 80%–90% FC) during the water‐sensitive tasselling and seedling stages, while applying mild deficit irrigation (e.g., W2: 65%–75% FC) during the jointing and filling‐to‐maturity stages, can optimize the T/ET <jats:sub>c</jats:sub> ratio and achieve synergistic improvements in grain yield (GY) and water productivity (WP). This study enhanced the understanding of soil water's role in ET <jats:sub>c</jats:sub> partitioning in drip‐irrigated maize, providing a quantitative basis for optimizing irrigation scheduling to enhance both GY and WP.","PeriodicalId":14864,"journal":{"name":"Journal of Agronomy and Crop Science","volume":"22 1","pages":""},"PeriodicalIF":3.5,"publicationDate":"2026-04-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147720038","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
