OverviewAI-generated summary
Carmen A Johns investigates the genetic underpinnings of traits in tetraploid blackberry (Rubus). Her research focuses on identifying genetic loci associated with postharvest quality, sweetness, acidity, and prickle development. Johns has explored the genetic control of primocane fruiting in blackberry, validating diagnostic markers for this trait. She has also examined texture analysis methods for blackberry fruit and investigated diagnostic markers for flower sex and seedlessness in grape varieties.
Her work contributes to the advancement of molecular breeding programs for blackberries, aiming to improve fruit quality and cultivation efficiency. Johns collaborates with researchers including Margaret Worthington, Lacy Nelson, T. Mason Chizk, and John R. Clark, with whom she has co-authored multiple publications. Her research is supported by a publication record that includes studies on genome-wide association and genetic control of key plant characteristics.
