Cadmium (Cd) is a toxic heavy metal and a major environmental pollutant that acts as a significant abiotic stress factor in plant systems. Its contamination poses a persistent threat to both ecosystems and food safety, with important implications for phytoremediation and broader environmental management strategies. In this article, we present a perspective on the role of the Nitrate Transporter 1 (NRT1) family in plant Cd research, a topic that warrants further investigation given that emerging evidence has linked NRT1 members to Cd tolerance and to the modulation of Cd uptake and accumulation in model species, crop plants of food safety importance, and plant species with relevance to Cd management research. Although functional studies remain relatively limited, current evidence suggests and highlights that specific NRT1 isoforms influence Cd distribution and plant growth under stress conditions. In addition, hormonal regulation, genetic engineering, and emerging biotechnological tools provide opportunities to fine-tune NRT1 activity. We also outline key priorities for future research. Overall, this perspective offers a forward-looking view on leveraging NRT1 transporters and related genes for biological engineering strategies aimed at improving plant performance and food safety in Cd-contaminated environments, while contributing to broader Cd mitigation efforts.</p>","PeriodicalId":20177,"journal":{"name":"Planta","volume":"263 4","pages":""},"PeriodicalIF":3.8,"publicationDate":"2026-03-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC12957033/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147348871","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

AI-driven multiscale virtual plant cell modeling is emerging as a pivotal paradigm for deciphering complex biological processes in plants. By integrating dynamic processes across molecular, subcellular, and tissue scales, this framework enables systematic simulation from protein interaction prediction to emergent tissue functions, significantly enhancing our understanding of plant environmental responses and developmental mechanisms. This review comprehensively summarizes key technological advances in multiscale modeling, including neural network-assisted molecular interaction prediction, virtual plant tissue simulator construction, deep vision-based 3D reconstruction techniques, and cross-scale dynamic coupling algorithms. It highlights the application value of generative adversarial networks (GANs), transfer learning, and multi-omics integration strategies in addressing data scarcity and cross-species modeling challenges. The review also discusses validation methodologies such as in vitro experimental verification, evolutionary conservation analysis, and uncertainty quantification. In applied contexts, multiscale modeling offers novel insights for plant metabolic engineering, developmental programming simulation, and stress response prediction, while identifying current bottlenecks in parameter transfer accuracy, model interpretability, and computational efficiency. Future directions, including quantum computing-enabled real-time simulation, agricultural digital twin systems, and brain-inspired autonomous models, are explored.

Root-knot nematodes are believed to intensify the severity of Fusarium wilt in common bean, and specific genomic regions are understood to be associated with the host response, whether conferring susceptibility or resistance. To elucidate the genetic mechanisms of this interaction, phenotypic traits were evaluated in greenhouse trials, followed by associative mapping using a genome-wide association study (GWAS) approach. The plant material consisted of a core collection of 180 common bean genotypes from the Agronomic Institute (IAC, Campinas, Brazil) diversity panel. The effects of Fop and Mi were evaluated individually and in co-infection. Associative mapping was performed using the Bayesian information and linkage disequilibrium iteratively nested keyway (BLINK) model. When plants were infected with Mi, significant SNPs were detected on chromosomes Pv07, Pv08, and Pv10 based on gall counts.

Endophytes are microorganisms that asymptomatically reside in plant tissues proving to be valuable partners in the realm of sustainable horticultural disease management. Their prevalence and diversity on horticultural crops indicate that there is a large pool of such microbial taxa with underused potential for promoting plant health. These endophytes use a variety of mechanisms in their fight against pathogens, including direct antagonism, niche and nutrient competition, and triggering of host defense mechanisms. Signaling crosstalk of the endophytes with the host plants can reprogram pathways like jasmonic acid, salicylic acid, and ethylene, leading to primed immunity and enhanced stress tolerance. The creation of enzymes (chitinase, glucanase) and bioactive metabolites is the main mechanism of pathogen growth suppression, while antimicrobial compounds and secondary metabolites are aimed at defense. Recent advances point out the promising use of endophytic formulations as bio-coatings on fruits to limit their post-harvest diseases, thus making the endophytic concept an eco-friendly substitute for synthetic chemicals. Advancements in the development and commercialization of endophyte-based coating materials demonstrate that they hold much promise as a low-cost and environmentally benign disease management strategy for horticultural industries.The aim of this review is to summarize recent insights into the diversity, molecular and biochemical mechanisms of action against pathogens, and translational potential of the metabolites from endophytes. It also calls attention to the endophytic coating as a new type of endophyte application that represents a bridge between basic research and an actual commercial coating.

Salinity stress is one of the extreme abiotic stress factors that reduces rice yield (Oryza sativa L.) and affects about 20% of the worldwide irrigated rice growing area. The present analysis describes the molecular and physiological aspects of salinity tolerance in rice with particular reference to ion homeostasis, osmotic adjustment, and oxidative stress. High-affinity potassium transporters (HKT) and sodium/hydrogen exchangers (NHX) are necessary ion transporters for ion homeostasis in the cell under salt conditions, as ions are abundant outside the cell. However, the rise in reactive oxygen species (ROS) levels and their damaging effects on cellular machinery are suppressed by rice's enzymatic and non-enzymatic antioxidant mechanisms. Producing osmoprotectants such as proline and glycine betaine also assists rice plants in overcoming turgor and protecting protein structures in conditions of osmotic stress. Recent biotechnological practices such as using CRISPR/Cas9 gene editing approaches, transcriptomic research, and epigenetic change-wise phenotypes have opened novel avenues to improve the tolerance of rice plants to soil salinity. At the same time, other challenges exist, such as the polygenic nature of the trait and significant genotype by environmental interactions, which pose serious issues.
