“…Perhaps some sexual reproduction disorder that induces embryogenesis failure in cultivars could result in more nutrients and photosynthate being partitioned to promote the development of the mesocarp, the desirable edible part of the fruit. Consistently, it has been shown that both fruit size and fruit drop are negatively impacted by inadequate nutrient supplies to each developing fruitlet in various perennial fruit crops including both citrus and Chinese jujube (Song et al ., 2015; Sakhidin et al, 2019).…”

Summary The Chinese jujube (Ziziphus jujuba Mill.), a member of the Rhamnaceae family, is an important perennial fruit tree crop of substantial economic, ecological and nutritional value, and is also used as a traditional herbal medicine. Here, we report the resequencing of 493 jujube accessions, including 202 wild and 291 cultivated accessions at >16× depth. Our population genomic analyses revealed that the Shanxi–Shaanxi area of China was jujube's primary domestication centre and that jujube was then disseminated into East China before finally extending into South China. Divergence events analysis indicated that Ziziphus acidojujuba and Ziziphus jujuba diverged around 2.7 Mya, suggesting the interesting possibility that a long pre‐domestication period may have occurred prior to human intervention. Using the large genetic polymorphism data set, we identified a 15‐bp tandem insertion in the promoter of the jujube ortholog of the POLLEN DEFECTIVE IN GUIDANCE 1 (POD1) gene, which was strongly associated with seed‐setting rate. Integrating genome‐wide association study (GWAS), transcriptome data, expression analysis and transgenic validation in tomato, we identified a DA3/UBIQUITIN‐SPECIFIC PROTEASE 14 (UBP14) ortholog, which negatively regulate fruit weight in jujube. We also identified candidate genes, which have likely influenced the selection of fruit sweetness and crispness texture traits among fresh and dry jujubes. Our study not only illuminates the genetic basis of jujube evolution and domestication and provides a deep and rich genomic resource to facilitate both crop improvement and hypothesis‐driven basic research, but also identifies multiple agriculturally important genes for this unique perennial tree fruit species.

“…The sugar content, pH and mineral composition of fruits were also affected. To perform fruit thinning, some of the developing unripe fruits are removed to allow the remaining unripe fruits to have more photosynthetic products available to increase fruit size and improve quality [10][11][12]. Fruit thinning is also one of the best cultivation practices that may increase flower return the following season [13].…”

Fruit thinning is a cultivation technique that is widely applied in horticulture in order to obtain high-quality horticultural crops. This practice results in the discarding of a large number of thinned unripe fruits in orchards each year, which produces a great waste of agricultural resources and causes soil pollution that may be an important reservoir for pest and plant diseases. Current studies showed that bioactive compounds such as polyphenols, organic acids, monosaccharides and starches are present in unripe fruits. Therefore, we reviewed the bioactive components obtained from thinned unripe fruits, their revalorization for the food industry, their beneficial effects for human health and the methods for obtaining these components. We also performed a calculation of the costs and benefits of obtaining these bioactive compounds, and we proposed future research directions. This review provides a reference for the effective utilization and industrial development of thinned unripe fruits obtained from horticultural crops. Furthermore, revalorizing the waste from this cultural practice may increase the economic benefits and relieve the environmental stress.
