• The strength and consistency of genotypic differences in disease resistance determine the potential for resistance evolution in host populations that rely on vegetative reproduction. Here we surveyed infection intensity of host genotypes across space and time to estimate genotypic and environmental effects on quantitative disease resistance. • Cloned fragments of 12 Euthamia graminifolia geno...

The sunflower (Helianthus annuus), which belongs to the family of Asteraceae, is a crop grown worldwide for consumption by humans and livestock. Interspecific hybridization widespread sunflowers both in wild populations commercial breeding. current dataset comprises 250 bp 76 paired-end NGS reads six interspecific hybrids (F1). aimed expand Helianthus species genomic information benefit genetic...

Helianthus is an economically important and genetically diverse genus, containing both evolutionary model species and cultivated species. Genetic variation within this genus has been examined at many different scales, from genome size changes to chromosomal structure to nucleotide variation. The growing amount of genomic resources within the genus has yielded insights into the importance of pal...

The most abundant transposable elements (TEs) in plant genomes are Class I long terminal repeat (LTR) retrotransposons represented by superfamilies gypsy and copia Amplification of these superfamilies directly impacts genome structure and contributes to differential patterns of genome size evolution among plant lineages. Utilizing short-read Illumina data and sequence information from a panel o...
