Genome-wide association analysis and candidate gene prediction for drought tolerance in Vietnamese indigenous rice at the germination and seedling stages

Integrative GWAS and Transcriptome Analysis Reveal Genetic Architecture and Candidate Genes for Drought Tolerance During Soybean Germination

Drought stress severely limits soybean production, and understanding the genetic basis of drought tolerance at the germination stage is important for breeding tolerant varieties. In this study, a panel of 270 soybean accessions was used for phenotypic evaluation and a genome-wide association study (GWAS) of five drough...

Integrated QTL-seq and transcriptome analyses identify a DUF1677 candidate gene with a Predicted Kelch β-propeller-like fold associated with iron deficiency response in rice

Structural analyses indicated that OsFe2200 adopts a putative Kelch β-propeller-like fold, while additional structural comparisons identified β-propeller- and Kelch-like proteins as moderate confidence homologs, suggesting that OsFe2200 is a structurally conserved but sequence divergent protein.

QTL mapping and haplotype analysis reveal candidate genes for seedling-stage salinity tolerance in rice

Introduction Soil salinization is a major constraint on rice production, and severe salinity levels lead to pronounced yield losses. Therefore, elucidating the genetic architecture of salinity tolerance and identifying candidate genes underlying this trait are crucial for molecular design breeding. Methods In this stud...

Genome-wide association analysis of drought resistance and yield-related traits in maize inbred lines in Northwest China

Drought stress is a primary constraint on global maize production, significantly impairing plant growth, reproductive synchrony, and grain yield. To address this challenge, we aimed to identify SNPs and candidate genes associated with maize drought tolerance, with emphasis on grain yield (GY) and its drought resi...

Multi-environment genome-wide association study reveals genetic loci associated with drought tolerance during wheat germination

Integrating RNA-Seq, Transcription Factor Annotation, and WGCNA Identifies Key Candidate Genes in Upland Cotton Seedlings Under Short-Term Drought Stress

This study deepens the transcriptional-level understanding of drought stress responses in cotton and provides valuable gene resources for breeding drought-resistant cultivars.
