The paper identifies genetic variants in the shikimate dehydrogenase gene Sad1 that affect enzyme activity and homoserine accumulation in maize kernels through integrated metabolite profiling and genome-scale modeling.

This study examines how domestication and improvement in sorghum have affected genetic load and nitrogen-response variation by integrating genomic and phenotypic data.

This study identifies balancing and positive selection in sunflower genomic regions related to abiotic stress tolerance, finding that modern cultivars have higher deleterious mutation loads and that some ancestral alleles enhance salt tolerance.

The paper investigates how trans-eQTL hotspots contribute to phenotypic heterosis in maize by regulating non-additive gene expression through transcription factors.

This study estimates genetic parameters of yield-related traits in maize under different nitrogen conditions, finding that nitrogen-responsive traits are highly polygenic and show negative selection patterns.

This study uses GWAS to identify genetic loci associated with sunflower head diameter, finding 106 and 8 significant SNPs using MLM and farmCPU methods, respectively.

The paper identifies a historically balanced locus under recent directional selection in maize linked to nitrogen response traits, revealing genetic changes associated with modern breeding practices.

The paper applies genome-wide mediation analysis to maize data, identifying 736 mediating genes that explain 12.7% of phenotypic variance, with pleiotropic effects observed in 11% of genes.
