Genetic dissection and QTL validation of seedling root system architecture in Chinese wheat landraces

Genome-Wide Association Study and Identification of Core Candidate Genes for Shoot and Root Length in Wheat During Germination

The genetic architecture and core candidate genes for shoot length (SL) and root length (RL) at the germination stage are dissected and seven core candidate genes for SL and 13 for RL are identified, including three pleiotropic genes regulating both traits.

From Seedling Architecture to Grain: Linking Root and Shoot Traits with Yield Potential for Climate-Resilient Wheat Breeding

Improving wheat for climate change requires understanding how seedling root systems affect adult plant performance. We evaluated 116 spring bread wheat (Triticum aestivum L.) genotypes across 25 traits under non-limiting moisture conditions. Analysis of variance revealed significant genotypic variation (p < 0.01) for a...

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

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. In this study, a popul...

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

Harnessing the variability in root architecture and VsNGR gene expression for drought adaptation in common vetch.

Root system architecture (RSA) is a key determinant of drought adaptation, particularly in rainfed crops such as common vetch (Vicia sativa L.). This study evaluated RSA traits together with shoot and root biomass in seedlings of 27 vetch genotypes from six countries under control conditions and water stress induced by...

Mapping quantitative trait loci (QTLs) for plant architecture traits using a high-density genetic linkage map in diploid potato (Solanum chacoense)
