Cowpea (Vigna unguiculata L. Walp.) is a major crop grown mainly in the arid and semi-arid regions for food nutritional security. Its production, however, generally hampered by its susceptibility to sap-sacking aphids (Aphis craccivora Koch). Resistance breeding cowpea improvement against aphids, has been limited inadequate understanding of genes responsible resistance this cosmopolitan pest. The objective study was identify single nucleotide polymorphisms (SNPs) candidate genes, associated with aphids. evaluated 209 genotypes multi-parent advanced generation intercross (MAGIC) population, together 5 MAGIC parents, cross three different locations two seasons Uganda.

Identifying genetic markers for teak resistance to Ceratocystis wilt through associative mapping

Forestry An International Journal of Forest Research, Journal Year: 2025, Volume and Issue: unknown

Published: March 7, 2025

Abstract Ceratocystis wilt, caused by the fungus fimbriata, is one of most important problems in teak (Tectona grandis) production, negatively affecting yield and wood quality. In this study, we aimed to use whole-genome sequencing identify single-nucleotide polymorphisms (SNPs) associated with resistance C. fimbriata T. grandis. The 130 genotypes was evaluated using bark substitution method, lesion area assessed at 120 dpi. Through genotyping-by-sequencing analysis, 1.4 million high-quality SNPs were obtained used for genome-wide association studies via FarmCPU model. model demonstrated a good fit data showed high levels significance identified SNP variations. We three candidate variations linked trait wilt. Specifically, variation located on pseudochromosome 2, while two are found 15. These findings can be applied breeding programs enhancing either resistant clones directly or incorporating these as markers assisted selection programs.

Sesame Genomic Web Resource (SesameGWR): a well-annotated data resource for transcriptomic signatures of abiotic and biotic stress responses in sesame (Sesamum indicum L.)

Briefings in Functional Genomics, Journal Year: 2024, Volume and Issue: 23(6), P. 828 - 842

Published: June 4, 2024

Sesame (Sesamum indicum L.) is a globally cultivated oilseed crop renowned for its historical significance and widespread growth in tropical subtropical regions. With notable nutritional medicinal attributes, sesame has shown promising effects combating malnutrition cancer, diabetes, other diseases like cardiovascular problems. However, production faces significant challenges from environmental threats such as charcoal rot, drought, salinity, waterlogging stress, resulting economic losses farmers. The scarcity of information on stress-resistance genes pathways exacerbates these challenges. Despite immense importance, there currently no platform available to provide comprehensive sesame, which significantly hinders the mining various stress-associated molecular breeding sesame. To address this gap, here free, web-accessible, user-friendly genomic web resource (SesameGWR, http://backlin.cabgrid.res.in/sesameGWR/) been developed This provides key insights into differentially expressed genes, transcription factors, miRNAs, markers simple sequence repeats, single nucleotide polymorphisms, insertions deletions associated with both biotic abiotic stresses.. functional genomics annotations embedded were predicted through RNA-seq data analysis. Considering impact climate change importance study utmost understanding stress responses. SesameGWR will serve valuable tool developing climate-resilient varieties, thereby enhancing productivity ancient crop.

Genome-Wide Association Study Uncovers Loci and Candidate Genes Underlying Phytosterol Variation in Sesame (Sesamum indicum L.)

Agriculture, Journal Year: 2022, Volume and Issue: 12(3), P. 392 - 392

Published: March 11, 2022

Sesame is one of the most important oilseed crops grown worldwide. It provides diverse nutraceuticals—including lignans, unsaturated fatty acids (UFA), phytosterols, etc.—to humans. Among sesame’s nutraceuticals, phytosterols have received less attention from sesame breeders, although their biological and pharmacological functions been recorded. Therefore, in present study, we evaluated variation phytosterol contents 402 accessions two environments revealed associated loci candidate genes. Gas chromatography (GC) analysis unveiled that mainly contains four phytosterols: campesterol, stigmasterol, β-sitosterol, Δ5-avenasterol. β-sitosterol (1.6–4.656 mg/g) was major phytosterol, followed by campesterol (0–2.847 mg/g), stigmasterol (0.356–1.826 Δ5-avenasterol (0–1.307 mg/g). The total content varied 2.694 to 8.388 mg/g. Genome-wide association study identified 33 significant single nucleotide polymorphism (SNP) for traits, which Ch6-39270 Ch11-142842 were environmentally stable simultaneously linked with variation. Candidate genes screening indicated SINPZ1100015 encoding a NAC domain-containing protein 43 likely effect gene sesame. results this extend knowledge provide resources markers-assisted breeding high-phytosterol varieties.

Introduction: Sesame is an ancient oilseed crop containing many valuable nutritional components. The demand for sesame seeds and their products has recently increased worldwide, making it necessary to enhance the development of high-yielding cultivars. One approach genetic gain in breeding programs genomic selection. However, studies on selection prediction have yet be conducted. Methods: In this study, we performed agronomic traits using phenotypes genotypes a diversity panel grown under Mediterranean climatic conditions over two growing seasons. We aimed assess accuracy nine important single- multi-environment analyses. Results: single-environment analysis, best linear unbiased prediction, BayesB, BayesC, reproducing kernel Hilbert spaces models showed no substantial differences. average across these ranged from 0.39 0.79 both marker-by-environment interaction model, which decomposed marker effects into components shared environments environment-specific deviations, improved accuracies all by 15%-58% compared particularly when borrowing information other was made possible. Discussion: Our results that analysis produced moderate-to-high sesame. further enhanced exploiting interaction. concluded multi-environmental trial data could improve efforts cultivars adapted semi-arid climate.
