Traditional classifications based on position, morphology, and a few marker genes yielded static, coarse cell categories.

Environmental cues such as pathogen attack, drought, and wounding generate transient, spatially restricted cell states that bulk profiling masks, and these dynamics are best resolved by integrating single-cell data with spatial transcriptomics and live imaging. Comparative single-cell analyses extend these insights across evolution, revealing conserved core cell-type groups, lineage-specific innovations, and rapid transcriptomic rewiring in particular cell types. Emerging computational strategies mitigate orthology issues caused by genome duplications, enabling robust cross-species atlas alignment. These advances demonstrate that plant cell identity is dynamic, context-dependent, and distributed along continuous spectra. We argue that future frameworks should balance discrete cell-type labels with flexible state-based descriptions and integrate multiomic and spatial information to capture the full plasticity of plant cells, from ephemeral stress responses to millennial evolutionary changes.</div></div>","PeriodicalId":11003,"journal":{"name":"Current opinion in plant biology","volume":"90 ","pages":"Article 102854"},"PeriodicalIF":7.5,"publicationDate":"2026-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"146006761","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This process has been extensively characterized in <em>Arabidopsis thaliana</em>, particularly through studies of the floral repressor <em>FLOWERING LOCUS C</em> (<em>FLC</em>). In this mini review, we summarize recent advances in understanding the genetic basis of vernalization, focusing on how non-coding polymorphisms influence <em>FLC</em> transcript accumulation and expression of long non-coding RNAs, thereby altering vernalization requirement and efficiency. Variation in the quantitative expression of <em>FLC</em> and its homologs has shaped the evolution of diverse life-history strategies of Arabidopsis relatives within the Brassicaceae family. Dissecting how naturally occurring non-coding variants reconfigure the cis-regulatory landscape of <em>FLC</em>-like genes will be key to understanding the molecular basis of phenological diversity.

To maintain proper intracellular concentrations of biomolecules such as mRNAs and proteins, gene expression must be coordinated with cell size. Emerging evidence from diverse organisms, including bacteria, yeast, animals, and plants, demonstrates that transcriptional output scales with cell size, suggesting a conserved principle of gene regulation.

In this review, we summarize recent advances in uncovering the molecular and cellular principles of gene expression scaling with cell size across kingdoms.

This review focuses on two tethering complexes, the class C core vacuole/endosome tethering (CORVET) and the homotypic fusion and vacuole protein sorting (HOPS) tethering complex, which have been best studied in the model plant <em>Arabidopsis thaliana</em>. The activity of these complexes has been linked to the regulation of multivesicular endosomes with the vacuole membrane.

In plants, TEs constitute a substantial proportion of the genome and frequently cause large-effect mutations that impact gene regulation, methylation, and phenotype expression. These characteristics have recently positioned TEs as potential drivers of rapid local adaptation. However, this perspective is not always integrated with the broader understanding of fitness effects and neutral processes. Despite numerous associations between TEs and fitness-related traits, clear cases directly linking TE insertion, phenotype, and fitness in natural populations—i.e., genuine examples of local adaptation—remain rare in plants. Emerging population-genomic evidence presents a more complex picture: while some TE insertions may facilitate adaptation or rapid responses to environmental change, most are selected against and act as deleterious, selfish elements. The evolutionary dynamics of TEs are further modulated by genome architecture, reproductive system, and ecological context, underscoring their system-specific behavior. In this opinion piece, I argue that generalizing about the significance of TEs in local adaptation in plants is fraught with complexity and risks oversimplification. As sequencing technologies advance, integrating theoretical population genetics with large-scale comparative analyses and simulations across a wider range of species will be essential to more fully characterize the dynamics of TEs.</div></div>","PeriodicalId":11003,"journal":{"name":"Current opinion in plant biology","volume":"89 ","pages":"Article 102846"},"PeriodicalIF":7.5,"publicationDate":"2026-02-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145803139","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
