PSC1, a basic/helix–loop–helix transcription factor controlling the purplish‐red testa trait in peanut

Journal of Integrative Plant Biology, Journal Year: 2025, Volume and Issue: unknown

Published: Jan. 24, 2025

ABSTRACT Seed color is a key agronomic trait in crops such as peanut, where it vital indicator of both nutritional and commercial value. In recent years, peanuts with darker seed coats have gained market attention due to their high anthocyanin content. Here, we used bulk segregant analysis identify the gene associated purplish‐red coat identified novel encoding basic/helix–loop–helix transcription factor, P URPLE RED S EED C OAT1 ( PSC1 ), which regulates accumulation anthocyanins coat. Specifically, found that 35‐bp insertion promoter increased abundance mRNA. Transcriptomic metabolomic analyses indicated was result decreased expression anthocyanidin reductase (ANR), leading delphinidin, cyanidin, pelargonidin derivatives. Further revealed interacts AhMYB7 form complex specifically binds ANR suppress its expression, resulting accumulation. Moreover, overexpression content Arabidopsis thaliana peanut callus. Our study reveals new controls by regulating metabolism provides valuable genetic resource for breeding

Integration of BSA-seq and high-resolution mapping reveals genomic regions and candidate genes controlling seed oil accumulation in peanut (Arachis hypogaea L.)

Published: April 28, 2025

Increasing seed oil content (SOC) is a primary objective in peanut (Arachis hypogaea L.) breeding, meeting the rising global demand for edible oil. Quantitative trait loci (QTL) mapping can help to identify genes underlying SOC variation and develop markers enhance selection efficiency by marker-assisted breeding. In present study, three major stable QTL were identified on chromosome Arahy.08, using bulked segregant analysis (BSA) approach based whole-genome sequencing of F₈ recombinant inbred lines (RILs). The qSOCA08-1, explaining 11.41-20.97% phenotypic variation, was mapped 0.65 Mb genomic region. qSOCA08-2, accounting 25.57-39.40% located 1.04 physical interval. Finally, qSOCA08-3 up 17.31% region 1.02 Mb. genetic effects these assessed near‑isogenic (NILs), derived from residual heterozygous individuals, tetraploid germplasm panel. Potential candidate within intervals corresponding predicted participate biosynthesis peanut. summary, our study provides valuable resources tightly linked molecular breeding aimed at improving SOC.

Genome-wide identification of SWEET genes reveals their roles during seed development in peanuts

BMC Genomics, Journal Year: 2024, Volume and Issue: 25(1)

Published: March 7, 2024

Abstract Sugar Will Eventually be Exported Transporter (SWEET) proteins are highly conserved in various organisms and play crucial roles sugar transport processes. However, SWEET peanuts, an essential leguminous crop worldwide, remain lacking systematic characterization. Here, we identified 94 genes encoding the conservative MtN3/saliva domains three peanut species, including 47 Arachis hypogea , 23 duranensis 24 ipaensis . We observed significant variations exon-intron structure of these genes, while motifs domain structures remained conserved. Phylogenetic analysis enabled us to categorize predicted 286 from eleven species into seven distinct groups. Whole genome duplication/segment duplication tandem were primary mechanisms contributing expansion total number genes. In addition, investigation cis -elements potential promoter regions expression profiles across 22 samples uncovered diverse patterns AhSWEET peanuts. AhSWEET24 with highest level seeds A. hypogaea Tifrunner, was localized on both plasma membrane endoplasmic reticulum membrane. Moreover, qRT-PCR results suggested that twelve seed-expressed important regulation seed development four different varieties. Together, our provide a foundational basis for future investigations functions especially process development.

The current status of the genetic transformation of Arachis plants

Journal of Integrative Agriculture, Journal Year: 2024, Volume and Issue: unknown

Published: June 1, 2024

Peanuts (Arachis hypogaea) are vegetable oil, protein and forage crops. The genus Arachis contains nine intrageneric taxonomic sections, including 83 species. Most species wild plants widely serving as turfgrass plants. Moreover, can provide gene resources for broadening genetic diversity in peanuts. To date, several key genes have been identified using recombinant inbred lines of use engineering improving peanut has not popularized. This is because the lack a robust reliable transformation method However, evidence indicates that had reported 30 years ago. Therefore, there strong contradiction between unsuccessful transfer candidate into review summarized regeneration methods to deepen understanding transgenic technology

Looking in the Scaffold 22 Hotspot for Differentially Regulated Genes Genomic Sequence Variation in Romanian Blueberry Cultivars

Horticulturae, Journal Year: 2024, Volume and Issue: 10(2), P. 157 - 157

Published: Feb. 7, 2024

Since its domestication about a century ago in North America, highbush blueberry (Vaccinium corymbosum L.) has gained appreciation by consumers worldwide, and the demand for new varieties is increasing. Whole-genome resequencing can help plant breeders to decrease time needed create novel identifying genes linked fruit-quality traits. The present study analyzed genetic variability of eight V. genotypes, seven Romanian (‘Prod’, ‘Vital’, ‘Azur’, ‘Simultan’, ‘Delicia’, ‘Compact’, ‘Safir’), American variety, ‘Bluecrop’. analysis first ~10 Mb from scaffold 22, hotspot genomic variation, above-mentioned revealed multiple differences 11 upregulated 50 downregulated involved fruit growth development. Of these differentially regulated genes, two five were fully covered at least 1× coverage depth sequencing. genes’ sequence confirmed high region, with most presenting numerous SNPs some InDels, indicated that an attempted 10× medium-coverage sequencing yields useful preliminary data use breeding programs.
