Much of C. ohadii 's appeal as an emerging model lies in its robust fast growth, comparable to yeast even as a photoautotroph. Hence, the detailed physiological, biochemical, and molecular studies that followed rapidly, together with extensive omics datasets, have revealed several of its intriguing biological features. We provide a historical perspective unfolding the rise of this species from survival in the harsh desert crusts to a widely used standard for photodamage resistance, dynamic metabolism, and elevated growth and photosynthetic performance, frequently with prominent relevance for plant research. We also spotlight how this case study enables exploration of photosynthesis in harsh habitats. Further, we discuss challenges in the development of genetic tools for the growing community studying C. ohadii , and current biotechnological approaches aiming to exploit its prime genetic potential. Finally, we refer to guidelines of good practice for C. ohadii research as a highly stress‐resistant model.","PeriodicalId":214,"journal":{"name":"New Phytologist","volume":"6 1","pages":""},"PeriodicalIF":9.4,"publicationDate":"2026-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"149083835","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}

The stored photoassimilates ensure plant survival by vegetative propagation and to support subsequent shoot growth. The leaf‐generated main tuberigen signal, StSP6A, upon its transport to stolon, forms tuber‐inducing Tuberigen Activation Complex (TAC). Misregulation or redirection of StSP6A transport toward lateral buds contributes to aerial tuber formation, thereby adversely affecting underground tuber yield. The activity of TAC is inhibited by antituberigens, such as StAST1 and StTFL1, which compete with StSP6A and constitute anti‐TAC. In this review, we provide a comprehensive overview of the genetic and molecular mechanisms underlying underground and aerial tuber formation, their regulation by antituberigen factors, key genes controlling stolon‐to‐tuber transitions, the role of StSWEET‐StSUT transporters in establishing the source–sink relationship essential for tuber development, and the evolution and global dissemination of modern potato cultivars. Collectively, insights from potato provide a valuable framework for understanding the conserved and divergent mechanisms governing storage organ development in other economically important crops.","PeriodicalId":214,"journal":{"name":"New Phytologist","volume":"100 1","pages":""},"PeriodicalIF":9.4,"publicationDate":"2026-09-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"149077640","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}

We developed an ER‐anchored TurboID proximity labeling method to selectively enrich proteins entering the conventional secretory pathway in Arabidopsis thaliana . Quantitative proteomics under control and salt stress conditions identified dynamic secretome changes and showed that most enriched proteins carry N‐terminal signal peptides, supporting the utility of this approach for profiling conventional secretory proteins. Using this method, we found that sodium chloride (NaCl) stress remodels the conventional secretome by enhancing the secretion of a subset of cell wall‐associated proteins. We further identified Apoplastic EDS1‐Dependent 3 (AED3) as a salt‐induced secretory protein, confirmed its ER–Golgi‐dependent secretion, and demonstrated its role in salt tolerance. Overall, this study provides a useful approach for pathway‐specific profiling of the conventional plant secretome, enabling the discovery of dynamic secretory proteins involved in plant environmental responses.

Whether this intraspecific variability has community‐level consequences for plant and AMF communities is unclear. This study investigated whether introduced conspecific AMF affected a resident AMF and plant community. Mesocosms containing natural soils and a mixed plant community were inoculated with three conspecific isolates of Rhizophagus irregularis and grown for 17 wk. We measured AMF isolate abundance, plant performance (aboveground biomass, foliar phosphorus, seed production), and plant and AMF community response (diversity and composition). AMF isolate identity affected AMF isolate abundance though effects varied with host identity. Isolate identity affected aboveground biomass of two host species. A small shift in plant community composition, but not diversity, occurred between two isolate treatments. The most abundant isolate affected turnover of rare AMF taxa in the soil community but did not alter the dominant AMF community. Whether small community shifts would compound or stabilize over time remains to be seen. Given the growing use of AMF‐based agricultural and forestry products, often represented by a single genetic isolate, there is a pressing need to understand how intraspecific AMF variation fits within ecological frameworks.

In plants, the immune receptor Flagellin Sensing 2 (FLS2) perceives bacterial flagellin to trigger downstream signaling that culminates in PAMP‐triggered immunity (PTI). FLS2 protein levels are critical for effective PTI, yet the regulatory mechanisms governing its stability remain to be fully elucidated. Our previous work showed that the Arabidopsis Really Interesting Gene (RING) type ubiquitin ligase XBAT35.2 positively regulates plant immunity against bacterial pathogen Pseudomonas syringae pv tomato by promoting FLS2 stability. In this study, we demonstrate that XBAT35.2 interacts in vivo with two key ESCRT‐I complex components, VPS37‐1 and VPS28‐2. XBAT35.2 ubiquitinates VPS37‐1 with K48‐linked polyubiquitin chains, leading to its proteasomal degradation, and modifies VPS28‐2 with K63‐linked chains, reducing its interaction with FLS2. VPS37‐1 and VPS28‐2 play redundant, negative roles in FLS2‐mediated immunity by promoting vacuolar degradation of FLS2, displaying differential effects on distinct FLS2‐mediated immune responses. By targeting VPS37‐1 and VPS28‐2, XBAT35.2 intercepts this degradative pathway, thereby stabilizing FLS2 and enhancing host immunity. These findings uncover a novel regulatory circuit modulating FLS2 abundance and deepen our understanding of controlling the cell‐surface receptor homeostasis in plant immunity.

Based on the biogeochemical niche (BN) hypothesis and the Price equation, we linked realized BN, estimated by leaf elemental composition, to diversity loss and productivity increases after fertilization in a long‐term alpine nutrient addition experiment and across 18 Nutrient Network grasslands. We found that fertilization compressed community‐wide realized BN hypervolume and reduced elemental diversity, yet expanded species realized BN hypervolume. These changes together decreased plant diversity in alpine grassland and Nutrient Network grasslands. Mechanistically, the alpine grassland experiment showed that the reduction in plant diversity after fertilization resulted from two simultaneous processes: first, the loss of species whose realized BNs closely resembled those of their close relatives; and second, the suppression of coexisting highly phylogenetically plastic species that continued to persist in the communities. Additionally, persistent species' BN expansion enhanced population productivity, scaling to ecosystem productivity increase after fertilization. Our findings formalize a predictive framework linking grassland biodiversity and ecosystem functions to global change through quantifiable ecological niche and species compositional dynamics.

To address this gap, we experimentally depleted carbohydrate reserves via low‐CO 2 conditions and quantified C allocation to reserves and growth during recovery at ambient CO 2 in Fagus sylvatica juveniles. Trees with lower carbohydrate reserves following C depletion prioritized C allocation to storage, whereas trees replete with carbohydrates favored growth, demonstrating that internal carbohydrate status governs allocation priorities during recovery from periods of C limitation. Our findings show that storage‐growth allocation during recovery from C limitation is driven by internal carbohydrate status, identifying plant carbohydrate concentration as a key variable for parameterizing the substrate‐dependent sink strength that current process‐based vegetation models largely omit.
