Recent advancements in biofortification and genetic engineering have shown considerable promise in enhancing the nutritional content of staple crops, thereby improving global nutrition and health outcomes. Biofortification, the process of increasing the nutrient content of crops through conventional breeding techniques and genetic engineering, has expanded the possibilities by enabling precise modifications to enhance nutrient profiles. These technologies have led to crops with increased levels of pigments, iron, zinc, vitamin A, and other critical micronutrients. Despite the potential benefits, several challenges hinder the widespread adoption of biofortified and genetically engineered crops. Regulatory hurdles, consumer acceptance, and socioeconomic factors continue to be significant barriers. Additionally, the long-term environmental impacts and ethical considerations of genetic modifications continue to spark debate. Continued research and collaboration among scientists, policymakers, and stakeholders are essential to overcome these challenges. This review reports the current state of biofortification through genetic engineering, while also addressing the barriers to its adoption.

A combined bioinformatic and experimental approach was employed to identify stress-responsive lncRNAs and assess their regulatory functions. A total of 447 RNA-seq datasets from ABA, drought, and methyl jasmonate (MeJA) treated samples were analyzed to predict treatment specific lncRNAs, and a core set of multi-stress-responsive lncRNAs (mslncRNAs) was identified by intersecting lncRNA loci across conditions. This analysis identified 4176, 4886, and 4190 lncRNAs under ABA, MeJA, and drought, respectively, 54.33% of which were novel. Differential expression analysis yielded 2318, 2603, and 1788 stress-responsive lncRNAs, and a stringent filtering pipeline defined 287 high-confidence mslncRNAs. Functional enrichment of cis-neighboring genes implicated mslncRNAs in pathogen defense, phytohormone signaling, and abiotic stress responses. Competitive endogenous RNA (ceRNA) network analysis identified 232 endogenous target mimics (eTMs) interacting with 118 miRNAs whose targets are enriched in hormone signaling, stress responses, and core metabolic pathways, indicating that mslncRNAs act as molecular nodes within stress-responsive transcriptional networks. For the experimental validation firstly the expression of the candidate mslncRNA-84 and mslncRNA-189 was validated by RT-qPCR, and their induction by ABA, drought, and MeJA was consistent with in silico predictions. To further characterize their functions, T-DNA insertion lines disrupting these transcripts were subjected to ABA-sensitive germination and jasmonate-dependent growth inhibition assays, biotic stress assays with Pseudomonas syringae pv. tomato DC3000 (including DAB and trypan blue staining and colony-forming unit quantification), and drought survival assays. Collectively, these genome-wide and experimental data indicate that mslncRNAs represent candidate ceRNA-associated regulatory nodes that may contribute to crosstalk among ABA, drought, and MeJA signaling pathways, shaping stress-responsive transcriptional programs.</p>","PeriodicalId":20064,"journal":{"name":"Plant Molecular Biology","volume":"116 3","pages":""},"PeriodicalIF":3.7,"publicationDate":"2026-04-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147778376","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 review systematically synthesizes recent advancements and pinpoints critical bottlenecks in key areas of modern crop science research: high-throughput phenotyping, multiscale mechanics of crops, and numerical modeling of crop-environment interactions. Based on this synthesis, we propose and articulate a conceptual framework for the novel interdisciplinary field: “mathematical and physical crop science.” The framework establishes an integrated paradigm of “data-driven, mechanism-based, and system-predictive” research, structured as follows: (1) High-throughput phenotyping, coupled with artificial intelligence and machine learning-driven analysis, quantifies dynamic phenotypic traits emerging from genotype-by-environment interactions. (2) Multiscale mechanics of crops resolves the physical constraints governing crop structure and function across different scales. (3) Numerical modeling of crop-environment interactions simulates the dynamic interactions between crop physiological processes and environmental factors.

We compared six Arabidopsis thaliana accessions for early induction of the thermomemory regulator HSFA2 following 30 min of priming with mild heat or seven reactive short-chain volatiles and assessed survival after a priming–recovery–lethal heat regime. Several reactive GLVs enhanced survival across the panel; the magnitude of both survival and early HSFA2 induction was accession-dependent. Across accessions, priming outputs were decoupled from canonical thermomemory markers: Cvi-0 exhibited uniformly weak HSFA2 induction yet retained high survival after T2H priming, whereas C24 showed low HSFA2 responsiveness to mild heat but pronounced volatile-driven HSFA2 induction. Early induction of class A1 heat shock factor genes (HSFA1 paralogs) and the thermotolerance effector HSP101 also varied among accessions, further supporting the uncoupling of survival outcomes from core heat-shock regulators. We then contrasted Col-0 and Cvi-0 using transcriptome profiling under control and T2H conditions. Col-0 strengthened a canonical heat-response module during T2H exposure, whereas Cvi-0 showed weaker induction of HSFA2, HSFA7, HSP101, and multiple small heat shock protein genes, indicating reduced T2H responsiveness in Cvi-0 despite strong priming. Instead, Cvi-0 activated defense- and detoxification-associated programs and specialized metabolism, highlighting candidate modules that include ESP, ALD1, PR5, GSTU10, and CYP71B15.

Disease management often relies on disease resistant cultivars, but their overuse has led to the break down of resistance. As such, it is important to elucidate novel gene targets for clubroot tolerance. AINTEGUMENTA-LIKE 7 (AIL7), a transcription factor in the AP2/ERF family, has been observed to influence the expression of genes involved in biotic stress response when overexpressed in Arabidopsis seeds in our previous study. Here we evaluated the resistance of Arabidopsis lines that constitutively overexpressed AIL7, as well as an ail7 T-DNA mutant, to P. brassicae, and found that both mutant and overexpression lines displayed reduced clubroot symptoms and pathogen spore load in infected tissues. Targeted gene expression analysis revealed significant alterations in the transcript levels of genes linked to pathogen response, along with notable differences in those associated with salicylic acid (SA) and jasmonic acid (JA) defense pathways. Interestingly, the SA- and JA-related genes had a tendency for up-regulation in AIL7 overexpression and mutant lines in the absence, rather than presence, of P. brassicae, and phytohormone analyses confirmed these results. These findings indicate that phytohormone-mediated defense pathways are constitutively activated in Arabidopsis lines in which AIL7 is either overexpressed or knocked out, which likely contributes to a reduction in disease symptoms. Taken together, these findings suggest that AIL7 could be a potential target for improving plant responses to clubroot.

Numerous studies suggest that the PELOTA protein plays a distinctive role in determining either susceptibility or resistance to various plant pathogens, including viruses. Interestingly, PELOTA exhibits a dual function: while certain allelic variants confer resistance or susceptibility to diverse plant viruses, complete or severe disruption of its activity impairs fundamental processes of plant growth and development. In this review, we synthesize current knowledge of PELOTA-mediated mRNA surveillance across eukaryotes, critically examine its emerging role in shaping plant–virus dynamics, and assess the deleterious developmental consequences of its mutation in plants.

Despite their potential role in aroma formation, the molecular identity and functional properties of ADH family members in strawberry remain largely unexplored. Here, we present a comprehensive genome-wide analysis of the FaADH gene family in the cultivated strawberry genome. Eleven FaADH genes were identified and characterized based on gene structure, phylogeny, and promoter cis-element composition. Expression profiling across five fruit developmental stages revealed dynamic regulation of several isoforms, with FaADH5, FaADH8, and FaADH11 showing strong expression during early fruit development. These patterns were consistent with biochemical assays, which showed declining total ADH enzymatic activity as ripening progressed. Homology-based protein modeling and molecular docking predicted differential substrate affinities among isoforms, with FaADH5 and FaADH8 displaying favorable binding to 1-butanol and 1-hexanol. Molecular dynamics (MD) simulations further confirmed the structural stability of these interactions over time. The integration of expression, activity, and structural data supports a functional specialization within the FaADH family, with select isoforms likely contributing directly to the alcohol pool required for ester formation.
