Root PTI pathways can differ from their above-ground counterparts and have been well-characterised in the model plant Arabidopsis thaliana but are not well-defined in crops. Gene repurposing coupled with differences in root tissues and root architecture in tomato species (Solanum lycopersicum and S. pimpinellifolium) led us to hypothesise that signalling pathways of Solanaceous-specific PRRs diverge from canonical pathways. The objective of this study was to characterise PTI signalling pathways and responses (ROS, MAPK, gene expression, and growth inhibition) in roots of wild and domesticated tomatoes downstream of three immune receptors: the well-conserved SlFLS2 and the Solanaeceous-specific FLS3 and CORE. We find that Solanum root PTI responses are concentrated in early differentiating root regions compared to late differentiating regions or whole roots, and that FLS3 and CORE signalling pathways are overlapping but distinct from each other and from FLS2. Although the early differentiating root region had strong PTI responses across Solanum cultivars and species, different genetic backgrounds varied in their response dynamics. Our results underscore the complexity of PTI signalling across species and highlight the developmental-stage specificity of tomato root immunity.","PeriodicalId":222,"journal":{"name":"Plant, Cell & Environment","volume":" ","pages":""},"PeriodicalIF":6.3,"publicationDate":"2025-09-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144999375","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}

Reported 14C-ages indicate that NSC used to grow root tissues (growth NSC) can vary from < 1 year to decades. To understand the controls of this variability, we compared 14C-ages of leaf, branch, and root tissues from two conifers (Larix decidua, Pinus mugo) in a control valley site and an alpine treeline ecotone where low temperatures restrict tree growth. Our results of increasing respiration rate and NSC concentration with ecotone elevation suggest an excess of C assimilation over growth and an increase in fresh NSC supply. Greater flow of fresh NSC through needles and branches could explain their young growth NSC (< 2 years). A smaller inflow of fresh NSC into roots could explain older growth NSC ages, which increased from 2 to 10 years from the valley to the bottom of the ecotone, and then declined to 6 years at the ecotone top. Rather than species differences that were small, environmental conditions over years appear to be the primary driver of C allocation dynamics, which are reflected in the 14C-ages of fine roots.","PeriodicalId":222,"journal":{"name":"Plant, Cell & Environment","volume":" ","pages":""},"PeriodicalIF":6.3,"publicationDate":"2025-09-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144999343","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, these benefits are accompanied by significant reductions in the concentrations of essential nutrients in both foliar and edible tissues, posing potential global nutritional challenges. In this study, we grew three soybean cultivars (Clark, Flyer, and Loda) in ambient ( ~ 438 ppm) and elevated CO₂ ( ~ 650 ppm) conditions using open top chambers and measured changes in leaf-level physiological responses, biomass accumulation, and nutrient concentrations across developmental stages. Elevated CO₂ increased carbon assimilation and decreased stomatal conductance, which led to an increase in seed yield, while root biomass remained unchanged. Seed nutrient concentrations, particularly iron (Fe), zinc (Zn), manganese (Mn), boron (B), phosphorus (P), potassium (K), and magnesium (Mg), decreased at maturity. We hypothesize that reductions in seed mineral concentration resulted from enhanced carbon assimilation and biomass accumulation without a concomitant response in root biomass and nutrient uptake. This constrained the plant's ability to maintain nutrient status with increased yield at elevated CO₂, and this response was conserved across the cultivars included in this study. Future work is needed to further understand the molecular mechanisms associated with these physiological responses at elevated CO2 in soybean.","PeriodicalId":222,"journal":{"name":"Plant, Cell & Environment","volume":" ","pages":""},"PeriodicalIF":6.3,"publicationDate":"2025-09-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144991130","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}

By capturing transcriptomic changes at single-cell resolution, scRNA-seq enables reconstruction of developmental trajectories across diverse plant tissues. In this review, we summarize recent advances in the application of scRNA-seq to study both primary and secondary xylem development in monocots and eudicots. These studies have revealed distinct xylem cell types, including vessel elements, libriform fibers, and ray parenchyma cells, and provided insight into their lineage relationships. We also highlight key technical and analytical challenges that limit cross-study comparisons, including inconsistent bioinformatic pipelines, variability in protoplasting efficiency, and the use of potentially misannotated marker genes. To address these limitations, we discuss the integration of in situ transcriptomic profiling using laser microdissection, which provides more accurate cell-type annotation and supports the current best working model of xylem developmental lineages. Finally, we suggest future directions for improving xylem developmental studies, including deeper integration of spatial and single-cell technologies to overcome current limitations in resolving lignified tissues and to better understand xylem responses to environmental perturbations.","PeriodicalId":222,"journal":{"name":"Plant, Cell & Environment","volume":" ","pages":""},"PeriodicalIF":6.3,"publicationDate":"2025-09-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144990988","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}

Determinating of β-ODAP synthetase (BOS) will accelerate plant improvement and utilisation of those species containing β-ODAP. In this report, trace level of β-ODAP was confirmed in several cultivars of Pisum sativum, a close relative of L. sativus. Functions of LsBAHD3 and LsAAE3 were investigated via its transient expression in Nicotiana benthamiana, in vitro enzymatic activity assay and overexpression in hairy roots of L. sativus and P. sativum, etc. The results suggested that LsBAHD3 act as BOS, while LsAAE3 function as oxalyl-CoA synthetase to catalyse/promote β-ODAP biosynthesis. Further comparison and verification of LsBAHD3-specific and LsAAE3-specific protein interactome suggested that the LsBAHD3-LsAAE3 module catalyses β-ODAP biosynthesis, and the ubiquitin/26S proteasome system is highly involved in the regulation of BOS and β-ODAP content and may be responsible for the different level of β-ODAP in L. sativus and P. sativum.

To address this, we investigated the variation and the genetic basis of mineral content, including, among others, calcium, iron, phosphorus, and zinc, in a diverse panel of maize (Zea mays L.) grown across environments. Our results show that genetic variation significantly contributes to differences in mineral content. Genotype-by-environment interaction and environmental factors, such as reduced phosphorus fertilisation, substantially impact the ionome composition, particularly decreasing zinc content and altering grain quality. Correlations between the 12 minerals were mostly positive, with variation observed in mineral composition between tissues and in translocation from vegetative to generative tissue. In addition, elite lines exhibited distinct mineral profiles compared to landraces. Genome-wide association mapping revealed a quantitative inheritance of the minerals and few common quantitative trait loci. Significantly associated markers were found in proximity to candidate genes involved in processes like mineral transport, detoxification and storage, which represent potential targets for marker-assisted selection to improve nutritional quality in maize. In conclusion, our results highlight the temporal and spatial dynamics of the maize ionome as a basis toward its targeted design for future agriculture.","PeriodicalId":222,"journal":{"name":"Plant, Cell & Environment","volume":" ","pages":""},"PeriodicalIF":6.3,"publicationDate":"2025-09-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144991139","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}

This study aimed to establish a framework (isolate-select-construct) for tailoring simplified salt-tolerant synthetic microbial communities (SynComs) and explore how they confer salt stress resistance to the plant. First, a total of 512 strains were isolated from the high-salt rhizosphere soil of Populus euphratica through high-throughput cultivation. Among these, nine strains were further selected for their salt-tolerant and growth-promoting abilities, with three isolates identified as key microbes, including hub microbes, keystone taxa and biomarkers. Guided by a function-driven strategy, we constructed five distinct SynComs, with SynCom5, SynCom7 and SynCom9 showing the most significant improvement in the growth of hybrid Poplar 84K (Populus alba × Populus glandulosa). Mechanistic investigations revealed that these SynComs can increase resistance to salt stress by directly reducing oxidative stress, adjusting osmolytes and balancing ions. Additionally, these SynComs were observed to recruit specific root-associated bacterial consortia that enhance the adaptability of poplar to salt stress. Overall, this study lays the groundwork for designing SynComs that promote plant growth and offers insights into harnessing specific microbial communities to boost plants' salt resistance.","PeriodicalId":222,"journal":{"name":"Plant, Cell & Environment","volume":" ","pages":""},"PeriodicalIF":6.3,"publicationDate":"2025-09-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144991089","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}

High crop diversity increased maize shoot biomass by 56%-87% and reduced drought-induced root biomass loss by 14%-59% compared to low crop diversity. Root diameter increased by 1.7-2.5 times leading to better drought tolerance by 2.2-2.7 times, and stabile key rhizosphere microbiota. The complexity of the rhizosphere bacterial network increased with crop diversification, and the keystone taxa (such as biofilm-producing Pseudomonas ) raised maize drought tolerance by increasing rhizosphere water retention. These microbiota increased habitat resilience under drought, increasing ecosystem provision and regulatory functions. Activities and hotspot areas of enzymes related to carbon and nitrogen cycling decreased with crop diversification, but changed minimally under drought, indicating that this enzymatic resilience could contribute to maize drought tolerance.
