“…Silencing of the E1 component subunit alpha of the pyruvate dehydrogenase, involved in glucose metabolism and in the conversion of pyruvate to acetyl-CoA, has been reported to inhibit glycolysis, and accelerate ripening in strawberry, as a consequence of ATP and respiration repression ( Wang et al., 2017 ). Luo Y. et al. (2020) suggested that this inhibition of glycolysis is an important factor for ripening and could be induced by ABA and sucrose, supported by the observation that GAPDH , another key enzyme in glycolysis, was downregulated after treatment with ABA and sucrose in strawberry fruit.…”

“…Furthermore, other studies focused on the interaction between ABA and sucrose signaling in promoting ripening-associated processes. Indeed, it was recently described that treatments with exogenous ABA and sucrose greatly accelerate strawberry and grape fruits ripening, being the effect obtained much more intense than with either sucrose or ABA alone ( Jia et al., 2016 ; Jia et al., 2017 ; Luo Y. et al., 2020 ). Grapes were collected and treated with different concentrations of ABA and sucrose (100 μM ABA and 16 mM sucrose) ( Jia et al., 2017 ) and green-stage strawberries were sprayed with 95 μM ABA and 100 mM sucrose, and collected fully ripe ( Luo Y. et al., 2020 ).…”

Differentially expressed genes have been observed between the three aforementioned treatments (ABA, sucrose and ABA + sucrose), suggesting that the differences are due to the synergistic action between ABA and sucrose, and not due to the additive effects of two independent routes ( Luo Y. et al., 2020 ).…”

Sugars play a key role in fruit quality, as they directly influence taste, and thus consumer acceptance. Carbohydrates are the main resources needed by the plant for carbon and energy supply and have been suggested to be involved in all the important developmental processes, including embryogenesis, seed germination, stress responses, and vegetative and reproductive growth. Recently, considerable progresses have been made in understanding regulation of fruit ripening mechanisms, based on the role of ethylene, auxins, abscisic acid, gibberellins, or jasmonic acid, in both climacteric and non-climacteric fruits. However, the role of sugar and its associated molecular network with hormones in the control of fruit development and ripening is still poorly understood. In this review, we focus on sugar signaling mechanisms described up to date in fruits, describing their involvement in ripening-associated processes, such as pigments accumulation, and their association with hormone transduction pathways, as well as their role in stress-related responses.

“…Additionally, sucrose can induce ABA accumulation and promote strawberry fruit ripening by ABAdependent and -independent mechanisms (Jia et al, 2016;. In a recent study, Luo et al (2019) showed that both ABA and sugar play a synergistic role in promoting strawberry fruit ripening, including anthocyanin accumulation. Finally, methyl jasmonate (MeJA) treatment has also been shown to increase anthocyanin accumulation in strawberry fruit (Concha et al, 2013).…”

Anthocyanins are the principal color-producing compounds synthesized in developing fruits of strawberry (Fragaria spp.). Substantial natural variation in color have been observed in fruits of diploid and octoploid accessions, resulting from distinct accumulation and distribution of anthocyanins in fruits. Anthocyanin biosynthesis is controlled by a clade of R2R3 MYB transcription factors, among which MYB10 has been shown as the main activator in strawberry fruit. Here, we show that MYB10 mutations cause most of the anthocyanin variation observed in diploid woodland strawberry (F. vesca) and octoploid cultivated strawberry (F. ×ananassa). Using a mapping-by-sequencing approach, we identified a gypsytransposon insertion in MYB10 that truncates the protein and knocks out anthocyanin biosynthesis in a white-fruited F. vesca ecotype. Two additional lossof-function MYB10 mutations were identified among geographically diverse whitefruited F. vesca ecotypes. Genetic and transcriptomic analyses in octoploid Fragaria spp. revealed that FaMYB10-2, one of three MYB10 homoeologs identified, residing in the F. iinumae-derived subgenome, regulates the biosynthesis of anthocyanins in developing fruit. Furthermore, independent mutations in MYB10-2 are the underlying cause of natural variation in fruit skin and flesh color in octoploid strawberry. We identified a CACTA-like transposon (FaEnSpm-2) insertion in the MYB10-2 promoter of red-fleshed accessions that was associated with enhanced expression and anthocyanin accumulation. Our findings suggest that putative cis regulatory elements provided by FaEnSpm-2 are required for high and ectopic MYB10-2 expression and induction of anthocyanin biosynthesis in fruit flesh. We developed MYB10-2 (sub-genome) specific DNA markers for marker-assisted selection that accurately predicted anthocyanin phenotypes in octoploid segregating populations.

Glycosyl hydrolase family 9 (GH9) cellulases play a crucial role in both cellulose synthesis and hydrolysis during plant growth and development. Despite this importance, there is currently no study on the involvement of GH9-encoding genes, speci cally VaGH9s, in abscission zone formation of rabbiteye blueberries (Vaccinium ashei). In this study, we identi ed a total of 61 VaGH9s in the genome, which can be classi ed into three subclasses based on conserved motifs and domains, gene structures, and phylogenetic analyses. Our synteny analysis revealed that VaGH9s are more closely related to the GH9s of Populus L. than to those of Arabidopsis, Vitis vinifera, and Citrus sinensis. In-silico structural analysis predicted that most of VaGH9s are hydrophilic, and localized in cell membrane and/or cell wall, and the variable sets of cis-acting regulatory elements and functional diversity with four categories of stress response, hormone regulation, growth and development, and transcription factor-related elements are present in the promoter sequence of VaGH9s genes. Transcriptomic analysis showed that there were 22 differentially expressed VaGH9s in fruit abscission zone tissue at the veraison stage, and the expression of VaGH9B2 and VaGH9C10 was continuously increased during fruit maturation, which were in parallel with the increasing levels of cellulase activity and oxidative stress indicators, suggesting that they are involved in the separation stage of fruit abscission in Vaccinium ashei. Our work identi ed 22 VaGH9s potentially involved in different stages of fruit abscission and would aid further investigation into the molecular regulation of abscission in rabbiteye blueberries fruit. Key messageThe genomic location and stage-speci c expression pattern of GH9 genes reveal their critical roles during fruit abscission zone formation in Vaccinium ashei.
