Advanced biotechnological interventions, particularly gene delivery technologies, offer promising alternatives; however, conventional gene transfer methods in plants often suffer from low efficiency and substantial limitations. This study investigates the potential of selenium nanoparticles (SeNPs)—commonly used in mammalian gene therapy—for gene delivery in plants, and compares their performance to polyethyleneimine-functionalised single-walled carbon nanotubes (PEI-SWNTs), a known gene delivery vector in plant systems. Chemically synthesised SeNPs (approximately 20 nm) and PEI-SWNTs were characterised and applied to <i>Arabidopsis thaliana</i> leaves and roots. Two DNA constructs encoding green fluorescent protein (GFP)—a plasmid vector (35S-eGFP-nosT) and a linear gene cassette—were used to evaluate nanoparticle-mediated gene delivery efficiency. Phytotoxicity was assessed through visible symptoms such as chlorosis and necrosis, while delivery success was measured via GFP fluorescence and gene expression analyses. SeNPs exhibited significantly lower phytotoxicity than PEI-SWNTs. In terms of gene delivery, SeNPs demonstrated higher efficiency in transporting linear DNA constructs, while PEI-SWNTs were more effective for plasmid DNA delivery. SeNPs show considerable promise as gene delivery vectors in plants, particularly for linear DNA, because of their reduced toxicity and effective uptake. These findings highlight the potential of SeNPs for broader applications in plant biotechnology, warranting further evaluation across different plant species and genetic cargos.</p>","PeriodicalId":7977,"journal":{"name":"Annals of Applied Biology","volume":"188 1","pages":"269-284"},"PeriodicalIF":1.8,"publicationDate":"2025-08-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145761496","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Through genome-wide analysis, 27 <i>PvCAF1</i> genes were identified, with gene sizes ranging from 108 to 618 amino acids and predicted molecular weights between 25.7 and 116.1 kDa. Phylogenetic analysis classified the <i>PvCAF1</i> genes into four distinct groups, and their chromosomal distribution revealed that <i>PvCAF1</i> genes were mostly located on chromosome 2, with 15 genes. Gene structure analysis showed that 74% of the <i>PvCAF1</i> genes were intronless, while others exhibited varied exon-intron arrangements. Gene duplication analysis identified nine duplication events, with Ka/Ks ratios indicating purifying selection. Synteny analysis showed that <i>PvCAF1</i> genes have the highest homology with those in <i>Solanum lycopersicum</i> and <i>Arabidopsis thaliana</i>.

The objective of this study was to investigate haplotype diversity, genetic variation and population structure by in silico phylogenetic analysis of mitochondrial <i>cox1</i> and <i>cytb</i> gene sequences of <i>V. destructor</i> isolates submitted to GenBank from different regions of the world. For this purpose, 509 sequences covering 399 bp of the <i>cox1</i> gene region and 215 sequences covering 628 bp of the <i>cytb</i> gene region were used for the analyses. A total of 37 polymorphic sites and 24 haplotypes were identified in the <i>cox1</i> sequences, while 31 polymorphic sites and 23 haplotypes were observed in the <i>cytb</i> region. Both gene regions exhibited high negative values for diversity and neutrality indices, indicating possible recent population expansion or selective pressures. This study also evaluated single nucleotide polymorphisms (SNPs) within GenBank-derived sequences and analysed their impact on haplotype differentiation and population structure. The results revealed considerable haplotype diversity, including several region-specific variants and potential signs of recent population expansion. The findings highlight ongoing microevolution within <i>V. destructor</i> populations, likely driven by host movement, acaricide use and ecological pressures.

Furthermore, studies have focused on optimising invertebrate sampling strategies and exploring their population dynamics in relation to YCS expression to determine which invertebrate species may be involved. Other research involves developing effective detection and surveillance approaches for YCS. This report reviews the YCS-related research published to date.

In this review, we examine how soil-borne pathogens influence rhizosphere microbiomes at the compositional and functional levels, and how the study of pathobiomes allows the identification of key microbial taxa that prevent or contribute to disease development. Although soil-borne pathogens induce contrasting effects on rhizosphere microbial diversity, shifts in rhizosphere microbiome structure and function have been consistently reported in a wide range of pathosystems. These shifts are induced by changes in root exudate patterns upon infection and subsequent defence response activation, and by the recruitment of beneficial microbial taxa by the infected plants. A better understanding of these alterations could help detect functional shifts linked with the plant defence response and identify resistance markers, thus opening new avenues for plant breeding or microbiome manipulation. Moreover, incorporating the pathobiome concept into the design of disease management strategies would assist in pinpointing possible biocontrol agents and identifying biomarkers for early disease detection.

In a field study, four commercial, Australian cultivars (‘Antas,’ ‘Denmark,’ ‘Leura’ and ‘Woogenellup’) were compared for flowering time across sowing dates. For each cultivar, the number of days to flower decreased around 30% from 215 days as the sowing date was delayed from February to May.

Sweet cherry (<i>Prunus avium</i>) is a crop with 82% of its production associated with animal pollination. Therefore, factors impacting pollination play a key role in sweet cherry production. These factors are often accounted for in pollinator management and orchard design; however, flower phenology, cultivar compatibility, and their impacts on yield are poorly understood and often not considered. We investigated how flowering overlap among cultivars and cultivar inter- and self-compatibility impact sweet cherry cultivars' suitability as pollen donors and recipients in <i>Beira Interior</i>, a key production region in Portugal. For this, we performed floral biology experiments in the field and under controlled greenhouse conditions. We compared the pollination success of compatible cultivars sharing one S-allele or none. We also assessed pollinator dependence and pollen limitation levels of the studied cultivars, as well as natural pollen deposition and fruit set levels. We observed that, although often overlooked, flower phenology is very important for determining suitable cultivar pairings, and flowering overlaps differ greatly from the existing literature, likely reflecting regional responses. Controlled hand pollination experiments revealed that pollen tube growth, a more straightforward and feasible pollination metric than fruit set in a mass-flowering crop with naturally low fruit set, can be effectively used to assess compatibility levels. Crossings between cultivars without common S-alleles and between cultivars sharing one S-allele resulted in similar pollen tube numbers and fruit set levels, indicating that both pairing types are suitable. Additionally, we detected pollination deficits in the studied cultivars, likely resulting from inadequate pollination services or poor pollen donor availability in the orchard. Altogether, we estimated the cultivar suitability of 81 different pairs of sweet cherry for the <i>Beira Interior</i> region. Our study highlights the importance of considering plant-related factors, namely flower phenology and cultivar compatibility, to develop targeted and effective management guidelines for sweet cherry producers, emphasising the significant impact these factors can have on production and the necessity of including them in orchard management and design.</p>","PeriodicalId":7977,"journal":{"name":"Annals of Applied Biology","volume":"188 1","pages":"229-245"},"PeriodicalIF":1.8,"publicationDate":"2025-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1111/aab.70044","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145761109","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
