Capsiate-Rich Fraction of Induces Muscular Glucose Uptake, Ameliorates Rosiglitazone-Induced Adipogenesis, and Exhibits Activation of NRs Regulating Multiple Signaling Pathways.

Capsiate is a key ingredient in the fruits of a nonpungent cultivar of . We investigated the effects of a extract (CE) and a capsiate-rich fraction of CE (CR) on nuclear receptors involved in multiple signaling pathways, glucose uptake, and adipogenesis in comparison to pure capsiate (Ca). Similar to the effect of Ca (100 μM), CE (500 μg/mL) and CR (100 μg/mL) caused the activation of PPARα and PPARγ (>3-fold), while CR also activated LXR and NRF2 (>2 fold).

Genomes of cultivated and wild Capsicum species provide insights into pepper domestication and population differentiation.

Pepper (Capsicum spp.) is one of the earliest cultivated crops and includes five domesticated species, C. annuum var.

Exploring and exploiting genetics and genomics for sweetpotato improvement: Status and perspectives.

Sweetpotato (Ipomoea batatas (L.) Lam.) is one of the most important root crops cultivated worldwide.

Discovery and characterization of sweetpotato's closest tetraploid relative.

The origin of sweetpotato, a hexaploid species, is poorly understood, partly because the identity of its tetraploid progenitor remains unknown. In this study, we identify, describe and characterize a new species of Ipomoea that is sweetpotato's closest tetraploid relative known to date and probably a direct descendant of its tetraploid progenitor. We integrate morphological, phylogenetic, and genomic analyses of herbarium and germplasm accessions of the hexaploid sweetpotato, its closest known diploid relative Ipomoea trifida, and various tetraploid plants closely related to them from across the American continent.
