This study compares the productivity and forage quality of perennial ryegrass cultivars and mixtures under different defoliation treatments, finding that grazing affects rankings differently than mechanical cutting.

This paper presents a chromosome-level, haplotype-resolved genome assembly of big trefoil using CiFi, revealing two phased haplotypes and supporting gene annotation.

The paper presents a near-complete, haplotype-resolved genome assembly of common buckwheat using trio-binning and Hi-C data, providing a valuable resource for genomic research and breeding.

This study identifies four novel candidate genes for stem rust resistance in Italian ryegrass using nested association mapping and high-density genotyping.

The paper applies MSAS and GBS to assess plant genetic diversity in grassland species, showing their complementary use in monitoring PGD.

This paper establishes the first NAM population in Italian ryegrass to identify candidate genes for seed shattering and related traits using ddRAD and whole genome sequencing.

The paper presents a chromosome-level haplotype-resolved genome assembly for Italian ryegrass, revealing gene order collinearity and sequence variation between haplotypes, and identifies QTL for stem rust resistance.

This study shows that recurrent phenotypic selection on spaced plants reduces seed shattering in Italian ryegrass, increasing seed yield.

The paper presents an improved chromosome-level genome assembly for perennial ryegrass using Hi-C data to correct structural errors in a previous assembly.

This study uses bulked segregant analysis with whole-genome sequencing to identify a 300 kb region associated with bacterial wilt resistance in Italian ryegrass, revealing candidate resistance genes.

This study analyzes genetic and phenotypic diversity in red clover accessions across Europe, revealing geographic genetic structure and local adaptation to breeding environments.

The paper presents a high-quality diploid genome assembly of Italian ryegrass, revealing extensive intergenic sequence variation due to its high heterozygosity.
