Abstract
Fruit shape is an important quality trait with implications in consumer decisions and marketability.
Researchers aim to improve the quality of fruit while reducing environmental impact and production costs by understanding genetic control of important traits such as fruit shape.
However, very little is known about the genomic mechanisms regulating fruit shape in Rosaceae crops.
Therefore, the use of model species is essential to expedite research and reduce associated costs.
Studies in the model plant Arabidopsis thaliana, and in crops as tomato or rice, have elucidated the role of ovate family proteins (OFPs) in the organ shape regulation through their interaction with brassinosteroid (BR) and gibberellin (GA) hormones and microtubules dynamics.
Transcriptomic data in Rosaceae species can be used to construct gene-coexpression networks that can contribute to elucidate the interaction of OFP, BR and GA genes in the regulation of fruit shape.
Here we constructed a co-expression network analysis in peach mutants with different fruit shape (flat and round). Our results suggest the conservation of fruit shape regulation in peach through the same pathway observed in model species.
Further analysis in other Rosaceae species will lead to the identification of the conservation level of such mechanisms in plants.
Ultimately, such findings will enhance the knowledge of fruit morphology regulation and facilitate the work of breeders.
