Molecular breeding of tomato: Advances and challenges

Journal of Integrative Plant Biology, Год журнала: 2025, Номер unknown

Опубликована: Март 18, 2025

ABSTRACT The modern cultivated tomato ( Solanum lycopersicum ) was domesticated from pimpinellifolium native to the Andes Mountains of South America through a “two‐step domestication” process. It introduced Europe in 16th century and later widely worldwide. Since late 19th century, breeders, guided by genetics, breeding science, statistical theory, have improved tomatoes into an important fruit vegetable crop that serves both fresh consumption processing needs, satisfying diverse consumer demands. Over past three decades, advancements molecular technologies, represented marker technology, genome sequencing, editing, significantly transformed paradigms. This article reviews research progress field breeding, encompassing sequencing germplasm resources, identification functional genes for agronomic traits, development key technologies. Based on these advancements, we also discuss major challenges perspectives this field.

SlH3 and SlH4 promote multicellular Trichome formation and elongation by upregulating woolly in tomato

Abstract Trichomes are tiny outgrowths on the plant epidermis that serve defensive purposes against various stresses. While regulatory mechanisms underlying unicellular trichome development well understood, those governing multicellular formation remain largely unexplored. In this study, we reveal a new pathway involving Hair3 (H3) and H4 genes, which encode C2H2 zinc finger proteins participate in tomato (Solanum lycopersicum). Using CRISPR-Cas9 to generate single- double-knockout lines, found h3 h4 single-mutant plants did not show altered characteristics compared wild-type plants. However, h3/h4 displayed decreased densities of types I, VI, VII trichomes, increased III V reduced leaf stem lengths type I revealing H3 redundantly regulate development. Notably, protein interaction assays demonstrated formed both homo- hetero-dimers, supporting their cooperative role. Transcriptome gene expression analyses identified as key regulators several genes involved development, including Woolly (Wo) its downstream targets, such Wox3b, MX1, H, HD8. Protein-promoter showed directly bind Wo promoter but rather interacted with Wo, thereby enhancing Wox3b. These findings establish provide novel insights into controlling

Evolution of HD-ZIP transcription factors and their function in cabbage leafy head formation

Frontiers in Plant Science, Год журнала: 2025, Номер 16

Опубликована: Апрель 3, 2025

The HD-ZIP protein, a unique class of transcription factors in plants, plays crucial role plant growth and development. Although some have been associated with leafy head formation Chinese cabbage, their regulatory mechanisms remain poorly understood. This study identified the family using HMM TBtools, constructed phylogenetic tree OrthoFinder, analyzed gene expansion contraction CAFE. Conserved features were MAFFT, MEME, TBtools; networks predicted ATRM PlantTFDB; expression was validated by qRT-PCR. In this study, sequences from 87 species to explore evolutionary history family. Despite significant variation across species, our findings indicated that proteins conserved both lower (Charophyta) higher where they potentially involved root, stem, leaf differentiation. analysis 22 Brassica III protein domains conserved. However, within pan-genome A 18 rapa differences observed auxin-related cis-elements promoter regions between heading non-heading cabbage varieties. RNA-seq wild-type A03 (heading) mutant fg-1 (non-heading) revealed 131 genes formed interaction network or clustered same branch as genes. Through GO enrichment qRT-PCR, several key candidate ssp. pekinensis identified. These established foundation for understanding molecular which regulated cabbage.

A two-step self-pollination mechanism maximizes fertility in Brassicaceae

Cell, Год журнала: 2025, Номер unknown

Self-pollination in self-compatible plant species often occurs prior to flower opening. By tracking the temporal progress of pollination Arabidopsis, we observed that pollen predominantly targets lateral region stigma unopened flowers. Notably, approximately 7 h after opening, flowers close, thereby pressing anthers toward central for a second self-pollination. This two-step self-pollination results doubling deposition, which significantly increases ovule-targeting ratio and improves fertility under pollen-limiting conditions, as evident anther-dehiscence-defective mutant myb108 environmental stress conditions. Analysis using gamete-interaction-defective mutants hap2/gcs1 dmp8 dmp9 revealed timely separation both events promotes fertilization recovery efficiency. A similar was two other self-pollinating but not outcrossing Brassicaceae species. mechanism represents reproductive assurance strategy annuals maximize unfavorable

The genetic control of herkogamy

Functional Plant Biology, Год журнала: 2024, Номер 51(5)

Опубликована: Апрель 30, 2024

Herkogamy is the spatial separation of anthers and stigmas within complete flowers, a key floral trait that promotes outcrossing in many angiosperms. The degree between pollen-producing receptive has been shown to influence rates self-pollination amongst plants, with reduction herkogamy increasing successful selfing self-compatible species. Self-pollination becoming critical issue horticultural crops grown environments where biotic pollinators are limited, absent, or difficult utilise. In these cases, poor pollination results reduced yield misshapen fruit. Whilst there growing body work elucidating genetic basis organ development, environmental control points regulating poorly understood. A better understanding developmental regulatory pathways involved establishing varying degrees needed provide insights into production flowers more adept at produce consistent, high-quality This review presents our current from genetics hormonal perspective.
