Consumer peach preferences and purchasing behavior: a mixed methods study.

Background: Peaches (Prunus persica (L.) Stokes) are grown in several regions throughout the USA, are eaten fresh, and used as ingredients in value-added processed products. An Internet survey was conducted to investigate Mid-Atlantic consumers' fresh and processed peach purchasing behaviors, and whether packaging certain numbers of peaches together, providing information about nutritional content, and other factors would increase purchases.

Rootstock-regulated gene expression patterns associated with fire blight resistance in apple.

Background: Desirable apple varieties are clonally propagated by grafting vegetative scions onto rootstocks. Rootstocks influence many phenotypic traits of the scion, including resistance to pathogens such as Erwinia amylovora, which causes fire blight, the most serious bacterial disease of apple. The purpose of the present study was to quantify rootstock-mediated differences in scion fire blight susceptibility and to identify transcripts in the scion whose expression levels correlated with this response.
