“…As sucrose treatment has been recently proposed as a postharvest strategy to maintain fruit and vegetables quality traits, its effect (50, 270, and 500 mM) on strawberry was also evaluated ( Li et al., 2019 ; Siebeneichler et al., 2020 ). While exogenous sucrose treatment increases internal glucose and fructose, the effect on pigment accumulation seems more anthocyanin-specific.…”

“…This differential effect on anthocyanin content could be explained by the fact that exogenous sucrose application up-regulated the expression of all structural genes of the flavonoid pathway, with the exception of the flavonoid 3’-hydroxylase , which, as mentioned above, drive the metabolic flux to the synthesis of cyanidin-derived anthocyanins ( Castellarin et al., 2006 ). However, the exact role of sucrose treatment in anthocyanin accumulation during fruit postharvest remains to be determined, as a function as mere metabolic substrate cannot be ruled out ( Siebeneichler et al., 2020 ).…”

Sugar Signaling During Fruit Ripening

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.

“…Sucrose plays a vital role in plant growth and development as well as the response to abiotic stress [43]. The application of sucrose in unripe strawberries resulted in the induction of ripening [44]. A study found that sucrose is one of most abundant metabolites in the glucose metabolic pathway, which plays an indispensable role in balancing photosynthetic activity in M. halliana [45].…”

Malus halliana is an iron (Fe)-efficient apple rootstock growing in calcareous soil that shows obvious 'greenness' traits during Fe deficiency. Recent studies have shown that exogenous sugars can be involved in abiotic stress. To identify the key regulatory steps of chlorophyll (Chl) biosynthesis in M. halliana under Fe deficiency and to verify whether exogenous sucrose (Suc) is involved in Fe deficiency stress, we determined the contents of the Chl precursor and the expression of several Chl biosynthetic genes in M. halliana. The results showed that Fe deficiency caused a significant increase in the contents of protoporphyrin IX (Proto IX), Mg-protoporphyrin IX (Mg-Proto IX) and protochlorophyllide (Pchlide) in M. halliana compared to the Fe-sensitive rootstock Malus hupehensis. Quantitative real-time PCR (RT-qPCR) also showed that the expression of protoporphyrinogen oxidase (PPOX), which synthesizes Proto IX, was upregulated in M. halliana and downregulated in M. hupehensis under Fe deficiency. Exogenous Suc application prominently enhanced the contents of porphobilinogen (PBG) and the subsequent precursor, whereas it decreased the level of δ-aminolaevulinic acid (ALA), suggesting that the transformation from ALA to PBG was catalyzed in M. halliana. Additionally, the transcript level of δ-aminolevulinate acid dehydratase (ALAD) was noticeably upregulated after exogenous Suc treatment. This result, combined with the precursor contents, indicated that Suc accelerated the steps of Chl biosynthesis by modulating the ALAD gene. Therefore, we conclude that PPOX is the key regulatory gene of M. halliana in response to Fe deficiency. Exogenous Suc enhances M. halliana tolerance to Fe deficiency stress by regulating Chl biosynthesis.

Moreover, drought stress increases the amount of abscisic acid in the plant, which reduces the growth rate (Siebeneichler et al., 2020).Research has shown that chitosan consumption is common in living organisms, including plants (Ngo et al., 2015). Chitosan boosts plants' defenses and can even increase resistance to plant pathogens (Sharma et al., 2019). Chitosan is derived from chitin, which is an antitoxic substance. Especially in low doses, chitosan can improve a plant's resistance to pathogens by strengthening its immune system (Ngo et al., 2015).
