Exudate flavonoid aglycones in the alpine species of Achillea sect. Ptarmica: Chemosystematics of A. moschata and related species (Compositae-Anthemideae).

In completion of our studies on Achillea exudate flavonoids, 11 alpine species of Achillea sect. Ptarmica were analyzed for their aglycone profiles. The study focuses on species commonly associated with A. moschata. The major flavonoid constituents found in exudates of most taxa were 6-hydroxyflavonol 3,6,4'-trimethyl ethers, except in A. ageratifolia and its subspecies, which are characterized...

Taxonomy and Genetic Differentiation among Wild and Cultivated Germplasm of Solanum sect. Petota

Because of their adaptation to a diverse set of habitats and stresses, wild species of cultivated crops offer new sources of genetic diversity for germplasm improvement. Using an Infinium array representing a genome-wide set of 8303 single nucleotide polymorphisms (SNPs), phylogenetic relationships and allelic diversity were evaluated within a diversity panel of germplasm from Solanum sect. Pet...
