Spatial transcriptomics (ST) and spatial metabolomics preserve spatial context, enabling <i>in situ</i> mapping of molecular and metabolic features in plant tissues. This review summarizes experimental and computational approaches for these technologies in plants, with emphasis on their applicability and limitations under plant-specific constraints such as cell wall structure, tissue complexity, and genome organization. We further discuss computational integration strategies, including deconvolution, spatial mapping, and cross-modal representation learning, highlighting dependence on reference quality and challenges related to data sparsity and batch effects. We also consider current limitations in applying foundation models to plant data due to limited plant-specific training resources and differences in regulatory architecture across species.

Understanding how soil environmental changes influence plant functional coordination is therefore critical for ecological restoration. Here, we investigated soil physicochemical properties and leaf functional traits across a rocky desertification gradient in a karst ecosystem of southwest China. Using leaf trait networks (LTNs) to evaluate changes in trait coordination and identify key regulatory traits under different desertification intensities. We found that severely desertified (SRD) habitats were characterized by alkaline soils with lower bulk density, soil organic carbon (SOC), and total phosphorus (TP), but relatively higher total nitrogen (TN), total potassium (TK), and calcium (Ca) than lightly and moderately decertified habitats. Along the rocky desertification gradient, LTNs exhibited progressively lower edge density but higher average path length, diameter, and modularity, indicating reduced overall trait integration together with stronger functional compartmentalization under increasing environmental stress. Hub traits also shifted systematically across desertification stages. In lightly rocky desertified habitats, leaf water content, leaf thickness, and leaf nitrogen concentration acted as central traits, whereas specific leaf P and chlorophyll became dominant in moderately desertified habitats. In SRD habitats, leaf thickness and leaf tissue density emerged as the major hub traits associated with structurally conservative strategies. Redundancy analysis further showed that soil nutrient availability, pH, bulk density, and calcium jointly regulated changes in network topology across desertification stages. Overall, our results demonstrate that rocky desertification drives stage-dependent reorganization of leaf trait coordination, reflecting a transition from resource-acquisitive to structurally conservative adaptive strategies as environmental constraints intensify.</p>","PeriodicalId":20224,"journal":{"name":"Plant Diversity","volume":"48 5","pages":"974-985"},"PeriodicalIF":5.9,"publicationDate":"2026-07-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC13615781/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"149063714","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In this study, high-throughput sequencing was used to analyze the diversity, assembly mechanisms, and potential sources of phyllosphere microbial communities at developmental stages. Key findings include: (1) Epiphytic and endophytic bacterial diversity peaked at the budding stage, then decreased and subsequently showed a gradual increase again toward the senescence stage, primarily driven by leaf nitrogen (N), phosphorus (P), and potassium (K). However, epiphytic and endophytic fungal diversity was significantly regulated by leaf N and P. (2) Assembly processes exhibited niche differentiation: the assembly of epiphytic bacteria during the color-changing and stable stages was dominated by stochastic processes, while deterministic regulation prevailed in other stages and in endophytic communities. Both assembly and network complexity were driven by leaf N and K dynamics. Fungal network complexity and deterministic regulation, in both epiphytic and endophytic niches, were promoted by leaf N and P during early stages but gradually weakened thereafter. (3) Active material exchange occurred between epiphytic and endophytic niches, and below-ground niches contributed more significantly to the fungal community. Overall, our results underscores that leaf nutrients modulate the diversity, assembly, and resultant compositional landscape of phyllosphere microorganisms at different developmental stages.

Using an integrative framework combining phylogenomics, cytogenetics, and floral pigment biochemistry, we reconstructed the genus's evolutionary history based on ITS and 48 nuclear markers from 392 accessions representing over 120 taxa. Our analyses resolved four major clades originating during a rapid Miocene radiation (12-10 Mya) and revealed extensive chromosome number variation (2<i>n</i> = 16-80) shaped by descending dysploidy and recurrent neopolyploidization.

Urban-related moderators (climatic region, air quality and build up area), phylogenetic group, leaf habits and study design were considered. Results showed that leaf thickness (LT) and leaf dry matter content (LDMC) significantly increased, while the photosynthetic rate under saturating light (<i>A</i> _sat), specific leaf area (SLA), chlorophyll content (<i>Chl</i>), and leaf area (LA) significantly decreased with urbanization. This pattern suggests that urbanization has driven plants to reorient their resource investment-return strategies toward a more conservative ecological strategy. Greater responses to urbanization were observed for angiosperm and deciduous species compared to gymnosperm and evergreen species. We also found leaf trait responses to urbanization are not uniform but depend on the interplay between anthropogenic (e.g., population density, built-up area) and natural (e.g., aridity, MAT) gradients.
