Integrating image-based phenotyping and GWAS to map tolerance to Spittlebug nymphs in interspecific Urochloa grasses

This study combines image-based phenotyping and GWAS to identify genetic loci associated with spittlebug tolerance in Urochloa grasses, finding 18 QTLs linked to plant damage traits.

Complex polyploid and hybrid species in an apomictic and sexual tropical forage grass group: genomic composition and evolution in Urochloa (Brachiaria) species

The paper characterizes genome composition and evolution in Urochloa species, identifying repetitive DNA and developing a genome model for polyploid and apomictic grasses.

Flow cytometry-based determination of ploidy from dried leaf specimens in genomically complex collections of the tropical forage grass Urochloa s. l.

The paper develops a flow cytometry method to determine ploidy in dried leaf specimens of Urochloa grasses, identifying ploidy levels in 353 accessions with CV <5%.

A new genome allows the identification of genes associated with natural variation in aluminium tolerance in Brachiaria grasses

This study identifies genes and molecular responses associated with aluminium tolerance in Brachiaria grasses using a new reference genome and QTL analysis.
