This study investigated the impact of S supply on Fe accumulation in four tetraploid wheat genotypes with different genetic backgrounds: a modern genotype, Svevo (Triticum turgidum subsp. durum), two ancient Khorasan wheats, Turanicum_21 and Etrusco (T. turgidum subsp. turanicum) and an ancient Polish wheat, Polonicum_2 (T. turgidum subsp. polonicum). Plants were grown hydroponically for 20 days under adequate (S = 1.2 mM) or limiting (L = 0.06 mM) sulfate levels, while receiving sufficient Fe (80 μM). Most genotypes exhibited reduced Fe accumulation under low S conditions, as expected. However, Polonicum_2 showed a unique response, accumulating significantly more Fe in both shoots and roots. This increased Fe accumulation was associated with a higher rate of PS release and upregulation of both TdYSL15 and TdIRO2 in roots of Polonicum_2, suggesting altered regulation of Fe deficiency responses. However, the expression pattern of TdIDEF1 was not correlated with TdYSL15 expression in this plant, suggesting the involvement of additional regulatory pathways beyond Fe supply. Finally, there was a strong correlation between O-acetylserine(thiol)lyase activity in shoot tissues and PS release rate across all genotypes. There is increased interest in Khorasan and Polish wheats as alternative crops for marginal areas, hence, these findings are noteworthy from a biofortification perspective and could potentially lead to innovations in agriculture that benefit food security.","PeriodicalId":220,"journal":{"name":"Plant Biology","volume":" ","pages":""},"PeriodicalIF":4.2,"publicationDate":"2025-05-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144075187","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This study presents positive legacy effects following a long-term, experimental drought and subsequent recovery in a mature mixed Norway spruce and European beech forest. Approximately 50 mature trees were exposed to five consecutive years of summer drought by completely excluding growing season precipitation from May 2014 to June 2019. Experimental drought recovery started in July 2019, after which the trees received natural precipitation. Taking advantage of the natural summer drought of 2022, following the unique long-term experimental drought, we investigated how drought legacy affects tree physiological responses to recurrent drought. The long-term experimental drought resulted in a 60% reduction in spruce leaf area, which was still reduced by 30% 4 years after the drought release. This slow recovery and associated reduced water use resulted in higher soil water availability under spruce during the 2022 drought, leading to significantly reduced physiological drought stress: about two times higher predawn leaf water potential, leaf gas exchange and sap flow density in legacy spruce compared to previous controls. Furthermore, neighbouring beech, displaying no leaf area reduction during the experimental drought, also had higher predawn leaf water potential and leaf gas exchange during the 2022 drought compared to previous controls, likely benefitting from the reduced water use of spruce. The slow recovery of spruce leaf area as a pronounced drought legacy effect proved advantageous for trees in alleviating physiological stress and overcoming future drought events.","PeriodicalId":220,"journal":{"name":"Plant Biology","volume":" ","pages":""},"PeriodicalIF":4.2,"publicationDate":"2025-05-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144075108","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"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 still unclear how plant vulnerability to drought in cloud ecosystems depends on the role of fog in relieving water stress via foliar water uptake (FWU). To investigate how plants in contrasting montane vegetation rely on fog to alleviate drought impacts, we measured 11 morpho-physiological traits in 10 phylogenetic pairs of plants in a montane grassland (~2000 m a.s.l.) and in a submontane forest (~700 m a.s.l.), both in southeast Brazil. Forest species are more sensitive to drought (i.e., lower conservative trait values, lower resistance to embolism, and lower FWU) than grassland species. Nonetheless, decreased frequency of fog events in the montane grassland may expose these species to a higher risk of dehydration, despite higher FWU capacity. Both forest and grassland vegetation are vulnerable to drought, but the vulnerability is attributable to different causes: higher sensitivity to drought in forests and lower fog exposure in grasslands. Therefore, for a more accurate description of plant responses to drought, we recommend introduction of theoretical-experimental models to assess drought vulnerability to changes in both atmospheric and soil water availability.","PeriodicalId":220,"journal":{"name":"Plant Biology","volume":" ","pages":""},"PeriodicalIF":4.2,"publicationDate":"2025-05-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144075193","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

With the projection that droughts will increase at the end of the century, it is important to find efficient and cost-effective methods to assess and monitor drought impacts. We leverage freely available satellite-based remote sensing images to study drought stress in forest. In this study, we evaluate the impact of intense and prolonged drought on temperate broadleaf deciduous forests using Sentinel-1 (S1) Synthetic Aperture Radar (SAR) time series data. For the first time, we used the S1-derived Dual Polarimetric Radar Vegetation Index (DpRVI) to detect and characterize drought effects in forests. Monthly median DpRVI deviations were obtained from S1 SAR images acquired between 13 October 2014 and 3 July 2023. The forest exhibited drought effects through a decline in DpRVI during droughts. These can be attributed to both reduced canopy branches and leaves, and decreased canopy water content. The onset of drought effects in 2018 was captured with negative median DpRVI deviations. An accumulated effect of the multi-year drought 2018-2020 occurred, as evident by increased negative median DpRVI deviations in the subsequent years up to 2021. This study demonstrates the potential of using S1-derived DpRVI to assess the impacts of droughts on broadleaf forest canopies. Further investigation should be carried out to discriminate the relative contributions of the declining canopy water content and changes in the amount and structure of canopy branches and leaves to the observed DpRVI decline.","PeriodicalId":220,"journal":{"name":"Plant Biology","volume":" ","pages":""},"PeriodicalIF":4.2,"publicationDate":"2025-05-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144075113","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The 'hotter drought' in Europe in 2018, and the consecutive drought years 2019 and 2020 caused large-scale growth declines and forest dieback. We investigated whether tree growth responses to the 2018-2020 drought can be explained by tree functional traits related to drought tolerance, growth and resource acquisition. We assessed the growth response, that is, growth during drought compared to pre-drought conditions of 71 planted tree species, using branch shoot increments. We used gap-filled trait data related to drought tolerance (P50, stomatal density, conductivity), resource acquisition (SLA, LNC, C:N, Amax) and wood density from the TRY database to explain growth responses, while accounting for differences in growth programmes (spring vs. full-season growing species). We found significantly reduced growth during the 2018 drought across all species. Legacy effects further reduced growth in 2019 and 2020. Gymnosperms showed decreasing growth with increasing P50 and acquisitiveness, such as high SLA, LNC, and Amax. Similar results were found for angiosperms, however, with a less clear pattern. Four distinct response types emerged: 'Sufferer', 'Late sufferer', 'Recoverer' and 'Resister', with gymnosperms predominately appearing as 'Sufferer' and 'Late sufferer'. 'Late sufferers' tended to be spring growing species. This study provides evidence for significant growth reductions and legacy effects in response to consecutive hotter droughts, which can be explained by functional traits across a wide range of tree species when accounting for fundamental growth programmes. We conclude that high drought tolerance bolsters growth reductions, while acquisitive species suffer more from drought.","PeriodicalId":220,"journal":{"name":"Plant Biology","volume":" ","pages":""},"PeriodicalIF":4.2,"publicationDate":"2025-05-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143952143","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
