“…AtSWEET11 and 12 are members of clade III of the SWEET genes, which are involved in disease development (Li et al 2018 ). It has been reported that OsSWEET12 (Li et al 2013 ) and AtSWEET11 (Wipf et al 2021 ) interact with AtRBOHD, a membrane NADP oxidase producing reactive oxygen species involved in defence-related processes. In line with the present interpretation, SWEETs were proposed to modulate the sucrose availability for pathogens (Fatima and Senthil-Kumar 2021 ).…”

“…It appears that the release-retrieval model provides a useful basis for a provisional explanation of the present results. As sugar transporters are regulated not only at transcriptional, but also at post-transcriptional and at post-translational levels (Liesche et al 2011 ; Wipf et al 2021 ; Garg and Kühn 2022 ), many additional molecular factors might participate in their modulation in Arabidopsis following phytoplasma infection, including the possibility of protein redistribution to regulate membrane permeability. Moreover, plasmodesmal connectivity is worthy to be considered, as it determines if and how far the phytoplasma effectors can disseminate into the tissues surrounding the sieve tubes and control the recruitment of nutrients.…”

Main conclusion Loss of CALS7 appears to confer increased susceptibility to phytoplasma infection in Arabidopsis, altering expression of genes involved in sugar metabolism and membrane transport. Abstract Callose deposition around sieve pores, under control of callose synthase 7 (CALS7), has been interpreted as a mechanical response to limit pathogen spread in phytoplasma-infected plants. Wild-type and Atcals7ko mutants were, therefore, employed to unveil the mode of involvement of CALS7 in the plant’s response to phytoplasma infection. The fresh weights of healthy and CY-(Chrysanthemum Yellows) phytoplasma-infected Arabidopsis wild type and mutant plants indicated two superimposed effects of the absence of CALS7: a partial impairment of photo-assimilate transport and a stimulated phytoplasma proliferation as illustrated by a significantly increased phytoplasma titre in Atcal7ko mutants. Further studies solely dealt with the effects of CALS7 absence on phytoplasma growth. Phytoplasma infection affected sieve-element substructure to a larger extent in mutants than in wild-type plants, which was also true for the levels of some free carbohydrates. Moreover, infection induced a similar upregulation of gene expression of enzymes involved in sucrose cleavage (AtSUS5, AtSUS6) and transmembrane transport (AtSWEET11) in mutants and wild-type plants, but an increased gene expression of carbohydrate transmembrane transporters (AtSWEET12, AtSTP13, AtSUC3) in infected mutants only. It remains still unclear how the absence of AtCALS7 leads to gene upregulation and how an increased intercellular mobility of carbohydrates and possibly effectors contributes to a higher susceptibility. It is also unclear if modified sieve-pore structures in mutants allow a better spread of phytoplasmas giving rise to higher titre.

“…Moreover, Sugar serves as the major ingredient for making sweets which are often used for flavoring, caramelizing, and forming a brownish color [15]. Wipf et al [16] explained that in the production of dried sweets, glucose and sucrose are added and soaked for about 12-24 hours, this process improves the taste, aroma, and texture. At present, the relationship between the production sweet of long beans, granulated sugar, and Ca(OH) 2 has not been provided.…”

Long beans are one type of vegetable that is quite popular in the community and has the potential to be developed. Although this type of vegetable gets damaged easily, its shell life is extended by drying which is achieved by adding Ca(OH)2 and soaking it in sucrose for about 12-24 hours. The solution helps to strengthen its texture before processing. This research aims to determine the effect of Ca(OH)2 and sugar treatment on the appearance of sweet long beans. Furthermore, it is designed as factorial experimental research with a completely randomized value consisting of two factors namely Ca(OH)2 (1%, 2%, 3%), and sugar solution (50%, 60%, 70%). The variables observed in sweet of long beans were reducing sugar, total moisture content, ash content, acidity, color test, yield test, and organoleptic test. Conclusively, the treatment using 1% of calcium hydroxide and 50% sugar concentration produced good characteristics with reduced sugar of 0.64 mg/100gr, moisture content of 8.53%, ash content of 2.17%, the acidity of 4.10, brightness level (L*) of 39.96, and a yield of 21.13%. Hence, it gives the best appearance, taste, texture, and overall acceptance on sweet of long beans.

“…A part of the sugars transported to fruit is utilized in physiological processes, whereas the other part is stored in vacuoles. Therefore, a comprehensive understanding of these processes is important for uncovering important players in physiologically relevant processes (Wipf et al 2021).…”

Sugars are fundamental metabolites synthesized in leaves and further delivered to fruit in fruit crops. They not only provide ''sweetness'' as fruit quality traits, but also function as signaling molecules to modulate the responses of fruit to environmental stimuli. Therefore, the understanding to the molecular basis for sugar metabolism and transport is crucial for improving fruit quality and dissecting responses to abiotic/biotic factors. Here, we provide a review for molecular components involved in sugar metabolism and transport, crosstalk with hormone signaling, and the roles of sugars in responses to abiotic and biotic stresses. Moreover, we also envisage the strategies for optimizing sugar metabolism during fruit quality maintenance.
