“…Analysis of fruit sugar and acid contents in a wide range of apple accessions suggested that fruit acidity rather than sweetness is likely to have undergone selection during apple domestication [24]. In this study, we found that unlike apple, sugar and acid metabolism were both undergone human selection during jujube domestication ( Fig 3A ).…”

Jujube (Ziziphus jujuba Mill.) belongs to the Rhamnaceae family and is a popular fruit tree species with immense economic and nutritional value. Here, we report a draft genome of the dry jujube cultivar ‘Junzao’ and the genome resequencing of 31 geographically diverse accessions of cultivated and wild jujubes (Ziziphus jujuba var. spinosa). Comparative analysis revealed that the genome of ‘Dongzao’, a fresh jujube, was ~86.5 Mb larger than that of the ‘Junzao’, partially due to the recent insertions of transposable elements in the ‘Dongzao’ genome. We constructed eight proto-chromosomes of the common ancestor of Rhamnaceae and Rosaceae, two sister families in the order Rosales, and elucidated the evolutionary processes that have shaped the genome structures of modern jujubes. Population structure analysis revealed the complex genetic background of jujubes resulting from extensive hybridizations between jujube and its wild relatives. Notably, several key genes that control fruit organic acid metabolism and sugar content were identified in the selective sweep regions. We also identified S-locus genes controlling gametophytic self-incompatibility and investigated haplotype patterns of the S locus in the jujube genomes, which would provide a guideline for parent selection for jujube crossbreeding. This study provides valuable genomic resources for jujube improvement, and offers insights into jujube genome evolution and its population structure and domestication.

“…Malate has also been shown to enhance the perception of sucrose during fruit consumption (Lobit et al, 2006). Thus, consumers and plant breeders have directly or indirectly selected for desirable malate contents during agricultural variety development in the past; however, the specific genotypes associated with malate trait selection remain uncharacterized (Ma et al, 2015a).…”

“…Metabolism of carbohydrates in fruit is complex. In general, starch is deregulated, resulting in an increase in total sugars and decrease in organic acids [6–8]. Upon reaching maturity, the starch content is substantially low, while the ratio of sugars to organic acids tends to be balanced.…”

This study examined the effect of debagging time on color and flavor / taste compounds in the non-red apple cultivar ‘Golden Delicious’ and red cultivar ‘Qinguan’ at mid and late stages of fruit development. Debagging briefly improved the red color in both cultivars, the peel of ‘Golden Delicious’ presenting pale-pink hue. However, rapid anthocyanin accumulation occurred in apple peel at a specific time (after 179 days after flowering (DAF) in ‘Qinguan’) and was unaltered by debagging time in the red cultivar ‘Qinguan’. Furthermore, untimely debagging had a detrimental effect on the content of anthocyanin. All sugars increased and organic acids decreased in apple pulp at mid to late stages of development. Bagging treatment reduced the content of most sugars and organic acids, as well as, the overall total. However, glucose and citric acid contents were higher in bagged fruit than non-bagged fruit; the maximum occurred in T7 treatment that was no-debagging at DAF 159 / 196 (‘Golden delicious’ / ‘Qinguan’), i.e., 24.35 and 0.07 mg g-1 FW in ‘Golden delicious’, and 38.86 and 0.06 mg g-1 FW in ‘Qinguan’, respectively. In a word, bagging treatment can alter the pattern of peel color development in apple fruit; however, it remains difficult to alter the timing of rapid anthocyanin accumulation as it is regulated solely by development. Moreover, bagging treatment reduced the total accumulation of sugars and organic acids, and even the over total in pulp, but increased the glucose and citric acid contents in apple pulp.
