“…Moreover, the size, color, and flavor of the fruit in this stage are significant. Similarly to many drupes such as peaches and plums, sweet cherry fruit development follows a double 'S' growth pattern [22]. In the present study, the characteristics of single fruit weight and TSS, soluble sugars, and anthocyanin contents of sweet cherry fruit increased continuously with fruit development; their main change stages mainly occurred after color conversion periods; and their growth changes exhibited a double 'S' change pattern.…”

Sweet cherries are economically important fruit trees, and their quality changes during development need to be determined. The mechanism of fruit quality changes in sweet cherries were determined by analyzing sweet cherry fruits at 12 developmental stages. The results showed that the soluble sugar, anthocyanin content, and hormones of sweet cherries all changed drastically during the color transition. Therefore, the fruits at the beginning of color conversion, at the end of color conversion, and at the ripening state were selected for the comprehensive analysis of their metabolome and transcriptome. Different sugars, such as D-glucose, sucrose, and trehalose, were identified in the metabolome. Dihydroquercetin, delphinidin-3-glucoside, cyanidin-3-rutincoside, and other flavonoid species were also identified. D-glucose and cyanidin-3-rutinoside were among the most important components of sweet cherry soluble sugars and anthocyanins, respectively. The transcriptional analysis identified key structural genes and nine transcription factors involved in the ABA, sugar, organic acid, and anthocyanin synthesis pathways, with the following specific regulatory patterns. NAC71, WRKY57, and WRKY3 regulate fruit sugar accumulation mainly by acting on INV, SPS, and SUS. MYC2 is involved in the synthesis of anthocyanin precursors by activating PAL and C4H, whereas TCP7 mainly regulates CHI and F3H. WRKY3, NAC71, and WRKY57 have important positive regulatory significance on anthocyanin accumulation, mainly by activating the expression of DFR, ANS, and 3GT.

“…Strawberries belonging to the Rosaceae family, are distinguished by their unique achenetum fruit architecture, where a single flower produces many achenes (fertilized ovaries), contrasting with the fleshy fruits of apples, peaches, and pears (Xiang et al, 2017; Liu et al, 2020). This distinction in fruit type, notably in strawberries and raspberries as aggregate fruits significantly influences morphology, production, storage, and distribution of their unique fruits (Xiang et al, 2017; Liu et al, 2020; Veerappan et al, 2021). Fertilization-induced fruit development in strawberries is of interest due to their unique flower and fruit structure.…”

The plant hormone auxin plays a crucial role in regulating important functions in strawberry fruit development. Although a few studies have described the complex auxin biosynthetic and signaling pathway in wild diploid strawberry (Fragaria vesca), the molecular mechanisms underlying auxin biosynthesis and crosstalk in octoploid strawberry fruit development are not fully characterized. To address this knowledge gap, comprehensive transcriptomic analyses were conducted at different stages of fruit development and compared between the achene and receptacle to identify developmentally regulated auxin biosynthetic genes and transcription factors during the fruit ripening process. Similar to wild diploid strawberry, octoploid strawberry accumulates high levels of auxin in achene compared to receptacle. Consistently, genes functionating in auxin biosynthesis and conjugation, such as TRYPTOPHAN AMINOTRANSFERASE OF ARABIDOPSIS (TAAs), YUCCA (YUCs), and GRETCHEN HAGEN 3 (GH3s) were found to be primarily expressed in the achene, with low expression in the receptacle. Interestingly, several genes involved in auxin transport and signaling like PIN-FORMED (PINs), AUXIN/INDOLE-3-ACETIC ACID proteins (Aux/IAAs), TRANSPORT INHIBITOR RESPONSE 1/AUXIN-SIGNALING F-BOX (TIR/AFBs) and AUXIN RESPONSE FACTOR (ARFs) were more abundantly expressed in the receptacle. Moreover, by examining DEGs and their transcriptional profiles across all six developmental stages, we identified key auxin-related genes co-clustered with transcription factors from the NAM-ATAF1,2-CUC2/ WRKYGQK motif (NAC/WYKY), BASIC REGION/ LEUCINE ZIPPER motif (bZIP), and APETALA2/Ethylene Responsive Factor (AP2/ERF) groups. These results elucidate the complex regulatory network of auxin biosynthesis and its intricate crosstalk within the achene and receptacle, enriching our understanding of fruit development in octoploid strawberries.

Holetta has different peach fruit varieties that could be used for various purposes. However, their fruit quality characteristics were not fully identified. Studies have indicated that the physicochemical qualities of peach fruits are influenced by a number of factors, with the varietal factor being one of the most important. Limited information regarding the factors that affect these qualities is available in the country, specifically at Holetta. Therefore, this study was initiated to evaluate the physicochemical quality properties of peach fruit varieties. Their physical quality traits such as fruit length, fruit diameter, fruit shape index, and average fruit weight, as well as chemical quality parameters like TSS, specific gravity, TA, ripening index, ascorbic acid content, and pH, were evaluated. The result revealed that both physical and chemical quality parameters were significantly affected by varietal factors. Amongst, Bonny Gold variety had the longest fruit length and Florida down had the largest fruit diameter. As far as average fruit weight is concerned, 88 − 18 W had the heaviest weight with 111.98 g, while Transvalia had the highest TSS and specific gravity. However, the Summersun and 9A-35C varieties recorded the highest TA and ripening index, respectively. Thus, the fruit’s physicochemical quality properties were highly altered with peach varieties.
