This hardwood species has been considered the best decorative wood in the world with extraordinary qualities of color, density and durability. Despite its commercial importance, molecular mechanisms regulating wood formation in teak are still obscure. In plants, the MYB transcription factors (TFs) are the master switches in the regulation of secondary cell wall biosynthesis. Previous transcriptome analyses of the secondary xylem of teak trees have identified high expression of MYB in young tree stems. In the present work, the full-length coding sequence of the TgMYB2 gene was isolated from teak young stems, characterized, cloned and constitutively overexpressed in tobacco plants. Phylogenetic relationships and molecular analyses recognized TgMYB2 as a 3R-MYB protein, which contains conserved motifs identified as R1-R2-R3 MYB repeats. In transgenic tobacco plants, the overexpressed TgMYB2 protein was localized exclusively in the cell nucleus, as expected for a transcription factor. The overexpressed TgMYB2 significantly modified secondary plant growth and improved biomass. Furthermore, we provide evidence that TgMYB2 plays an important role in the coordinated regulation of cellulose, hemicellulose, and lignin biosynthetic pathways.</p>","PeriodicalId":20064,"journal":{"name":"Plant Molecular Biology","volume":"115 4","pages":"92"},"PeriodicalIF":3.8,"publicationDate":"2025-07-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144732685","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}

However, its cultivation faces significant challenges from pests, diseases, and environmental stresses. Among these, Fusarium wilt (FW) caused by pathogen Fusarium oxysporum f. sp. pisi poses a severe threat, resulting in substantial yield losses globally. Four pathogenic races (1, 2, 5, and 6) of this fungus have been primarily identified, and its broad host range further complicates effective management. Traditional control methods including cultural practices, physical control, biological interventions, and chemical treatments have shown limited efficacy. Consequently, host-plant resistance has emerged as a sustainable and practical solution for managing FW. In this review, the advancements in genetics with modern molecular techniques such as SNP genotyping, QTL mapping, and marker-assisted selection for the development of FW resistant pea varieties were highlighted. Furthermore, we also discussed the omics techniques viz., transcriptomics, metabolomics and proteomics and innovative breeding techniques like CRISPR-mediated genome editing, speed breeding, and genomic selection for revolutionize FW resistance breeding programs in pea. Therefore, this review focuses on integrating cutting-edge molecular techniques with omics approaches to unravel Fusarium wilt defense mechanisms in garden pea, aiming to accelerate genetic gains and develop superior disease-resistant varieties for improved productivity and quality.</p>","PeriodicalId":20064,"journal":{"name":"Plant Molecular Biology","volume":"115 4","pages":"89"},"PeriodicalIF":3.8,"publicationDate":"2025-07-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144691203","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}

However, its cultivation is constrained by several abiotic stresses, notably sodicity, which significantly reduces productivity and is expected to worsen in the near future. In this study, a genome-wide association study (GWAS) was conducted to identify genomic regions and candidate genes associated with sodicity tolerance in rice. A rice association mapping panel consisting of 150 genotypes was evaluated for sodicity tolerance traits across four environments and genome-wide single nucleotide polymorphisms (SNPs) obtained using genotyping-by-sequencing (GBS) approach. The results revealed high phenotypic variation and heritability for six sodicity tolerance traits across the evaluated environments. The high-quality SNPs obtained were subjected to linkage disequilibrium (LD) block construction, resulting in 5,459 tag-SNPs, which were used for population structure and GWAS analyses. Population structure analysis revealed nine distinct sub-populations (k = 9) within the panel. GWAS, using three multi-locus models, identified 27 consistent and stable marker-trait associations (MTAs) for six sodicity tolerance traits across 10 chromosomes. A candidate gene search within the corresponding LD block regions identified 57 putative candidate genes associated with sodicity tolerance. Furthermore, gene-based haplotype analysis was conducted for these candidates and revealed that four genes-encoding ADP-glucose pyrophosphorylase, phenolics efflux transporter, DUF1296 family proteins, and F-box domain-containing proteins-exhibited significant differences among their haplotype groups.

MYB transcription factors play crucial roles in regulating plant secondary metabolism, including flavonoid biosynthesis. While the regulation of MYB transcription factors has been extensively studied in various species, research on their role in S. baicalensis remains relatively scarce.

Through heterologous overexpression of SbMYB111 in Arabidopsis thaliana and suppression expression in S. baicalensis, we demonstrated that SbMYB111 acts as a positive regulator in the biosynthesis of flavonoids. Furthermore, the yeast one-hybrid and dual-luciferase reporter gene assays validated that SbMYB111 activates the expression of SbC4H2, a key enzyme gene in the flavonoid biosynthesis pathway.

These enzymes polymerize glucose on the cytoplasmic side of the plasma membrane and export the glucan chain to the cell surface through an integral transmembrane (TM) channel. Structural studies of active plant cellulose synthases (CESAs) have revealed interactions between the nascent glucan chain and the side chains of polar, charged, and aromatic amino acid residues that line the TM channel. However, the functional consequences of modifying these side chains have not been tested in vivo in CESAs or other processive GT-2s. To test this, we used an established in vivo assay based on genetic complementation of CESA5 in the moss, Physcomitrium patens. For accurate prediction of glucan-interacting amino acid residues, we generated a complete homotrimeric molecular model of PpCESA5 using a combination of homology and de novo modeling. All-atom molecular dynamics-based analyses of contact metrics and interaction energy identified 23 amino acid residues with high propensity to interact with the nascent glucan chain within the TM channel or on the apoplastic surface of PpCESA5. Mutating any one of 18 of these amino acid residues to alanine, thereby removing their side chains, abolished or impaired CESA function, with the strongest effects observed upon the loss of charged amino acid side chains.

So far, CRISPR-Cas has been widely used to enhance yield, quality, stress tolerance, and nutritional value in various food crops. However, challenges such as reagent delivery in suitable explants, precise editing with minimal off-target effect, and generating transgene-free plants persist as major bottlenecks in most plant species. Components of CRISPR-Cas construct mainly Cas, guide RNA (gRNA), and selectable marker genes are often integrated into the host genome, which raises regulatory concerns. However, adapting advanced gene-editing strategies, including high-efficiency Cas endonucleases, DNA-independent RNP delivery, morphogenetic regulators, and grafting-mediated editing, are paving the way for transgene-free crop improvement while easing biosafety regulations. Further, regulatory frameworks for genome-edited crops vary globally, with several countries accepting them and others debating their legal status.
