OverviewAI-generated summary
John R. Clark's research focuses on the genetic underpinnings of fruit quality and related traits in various berry species, including blackberry and muscadine grapes. His work has identified specific genetic loci associated with fruit quality characteristics, such as postharvest quality and the reversion of drupelets in blackberries. He also investigates the role of particular genes, like glutathione S-transferase, in determining berry color in grapes.
Clark's scholarly output includes studies on the effect of harvest time and fruit firmness on blackberry quality, as well as the genetic control of prickles in tetraploid blackberry. His research extends to identifying unique quality attributes of Arkansas-grown fresh-market blackberries and analyzing their phenolic and volatile compounds. His work has been published in numerous peer-reviewed journals, contributing to a body of work that has garnered significant citations and an h-index of 37.
He is a highly cited researcher and leads an active research group at the University of Arkansas at Fayetteville. His collaborations include extensive work with Margaret Worthington, Renee T. Threlfall, T. Mason Chizk, and Luke R. Howard, all affiliated with the University of Arkansas at Fayetteville.
