Hormonal Interactions in Parthenocarpic Fruit Formation of Horticultural Crops
Published:30 Jan.2023 Source:Hortic Res
Floral plants usually need pollination and fertilization to set fruit, but the ovary of some horticultural crops of Cucurbitaceae, Solanaceae and Rosaceae could grow and bear fruit without pollination and fertilization, which is called parthenocarpy. Plant hormones play a key role in the regulation of parthenocarpic fruit development. Auxin, gibberellin, brassinolide and cytokinin can all induce parthenocarpic fruit formation, but the research on its key regulatory genes and mechanisms is not yet in-depth.
Recently, Horticulture Research launched (Advance Access) a review entitled "Hormonal interactions underlying parthenocarpic fruit formation in horticultural crops", which was finished by the Cucumber Genetic Breeding and Molecular Biology Team, School of Horticulture and Plant Protection, Yangzhou University.
This study reviewed the interaction mechanism between plant hormones and other factors (sugars, polyphenols) and polygenes from the aspects of the phenomenon of plant hormones inducing parthenocarpy, key regulatory genes and regulatory mechanisms, and revealed how plant hormones regulate the development of parthenocarpic fruits in horticultural plants through their synthesis, metabolism and signal transduction.
