The importance of horticultural plants, which include vegetables, fruits, oamentals, has been well-recognized.As an important part of ecosystem on earth, horticultural plants are necessary for lucid waters and lush mountains.Therefore, horticultural plant research is a key component of life sciences.For example,studies of the grapevine genome found that the gamma WholeGenome Duplication (WGD) event (The French-Italian Public Consortium for Grapevine Genome Characterization, 2007) is critical for the evolution of flowering plants (angiosperms).In-depth analyses of the plant genomes confirmed that polyploidy events are prevalent among flowering plants (Jiao et al., 2011).Some horticultural plants have been served as popular model systems for genetic studies.For instance, tomato has been widely used to study fruit development and ripening by gene editing technologies (Rodriguez-Leal et al., 2017;Soyk et al., 2017).
