One of the enzymes thought to be involved in plant responses to hypoxia is SuSy. Sucrose synthase proteins association to the plasma membrane is considered to be strong as the use of 0.5M NaCl, 0.1–1% triton X-100, 25 nm EDTA and other detergents barely solubilized SuSy from the plasma membranes (Amor et al., 1995; Carlson and Chourey, 1996). doi: 10.1104/pp.106.4.1659, Sheen, J., Zhou, L., and Jang, J.

Plant Physiol. Planta 217, 252–260. 281, 15625–15635. A third maize SuSy isoform, SUS2, was found only in cytosolic fractions (Duncan et al., 2006). Sucrose synthase FaSS1 plays an important role in the regulation of strawberry fruit ripening. Abdullah, M., Cao, Y., Cheng, X., Meng, D., Chen, Y., Shakoor, A., et al. Plant responses to hypoxia - is survival a balancing act? The results also revealed increased expression of both WUSCHEL (WUS) and CycD3, leading to the increased proliferation of meristematic cells. Plant Mol. The three maize sucrose synthase isoforms differ in distribution, localization, and phosphorylation. 129, 1664–1673. The Suc signal for flowering may be mediated by trehalose 6-phosphate (T6P). Interestingly, even a double mutant (sus2 and sus3) and a quadruple mutant (sus1, sus2, sus3, and sus4) did not show any seed-related phenotypes (Bieniawska et al., 2007; Barratt et al., 2009), suggesting that Arabidopsis SuSy are not important for seed sink strength. Plant Cell Environ. Localization of SuSy from tobacco (Nicotiana tabacum) pollen tubes, revealed two isoforms, one of which is associated with the plasma membrane and the other one is associated with the plasma membrane and is also found in the cytosol (Persia et al., 2008).

Although overexpression of cotton SUS in tobacco plants did not affect cellulose content (Coleman et al., 2006), its overexpression in poplar trees did increase their cellulose content, as well as cell-wall thickness and wood density (Coleman et al., 2009). Planta 210, 41–49. doi: 10.1371/journal.pone.0182334, Guerin, J., and Carbonero, P. (1997). However, because 90% suppression of SuSy activity in maize endosperm resulted in only a 40% reduction in starch, doubts were raised as to whether or not SuSy is directly involved in starch synthesis in sink tissues. 11, 67–75.

It is a nonreducing sugar with limited chemical reactivity and thus is utilized as a transport and storage molecule in most plants. Bioinformatics 8, 275–282. Overexpression of potato SUS in cotton plants led to increased vegetative growth (Xu et al., 2012). Fourteen SUS genes have been discovered in tobacco (Nicotiana tabaccum) (Wang et al., 2015) and 15 SUS genes have been identified in poplar (Populus trichocarpa) (An et al., 2014). C O2. (2018). Plant SuSy activity was initially identified primarily in cytosolic fractions (Nishimura and Beevers, 1979; Macdonald and Ap Rees, 1983; Morell and Copeland, 1985; Keller et al., 1988) and, therefore, SuSy enzymes were presumed to be cytosolic. Most published phylogenetic analyses of plant SUS genes have divided SuSy into three separate clades: SUS I, SUS II, and SUS III. D-fructose, sucrose and starch are commonly are formed in the green cells during photosynthesis. Sucrase, lactase and other pancreatic enzymes break down sucrose and lactose. Plant Mol. The main issues that need to be further explored are: (1) the regulation of SUS expression and intracellular localization of specific SuSy isozymes, (2) the co-evolution of SuSy and INV and the division of Suc cleavage between these two group of enzymes, (3) the differences between the SUS I, SUS II, and SUS III clades, and (4) the roles of SuSy in meristem and leaf development. Bot. Acad. Sci. Plant Physiol. Maize sucrose synthase-1 promoter directs phloem cell-specific expression of GUS gene in transgenic tobacco plants. Yang, N. S., and Russell, D. (1990). Oddly, in many of these papers, only the SUS I clade included a clear separation between eudicot and monocot species; whereas in the other clades, and the SUS II clade in particular, there was no clear separation between monocots and eudicots (Chen et al., 2012; Xiao et al., 2014; Li et al., 2015; Wang et al., 2015; Zhang et al., 2015; Zhu et al., 2017). Plant Cell Physiol. The SuSy in plasma membranes and cell walls and their production of UDP-G may be important for directing carbon toward cellulose or callose synthesis; whereas INV may direct carbon to other metabolic pathways. Enzymic properties of amyloplasts form suspension cultures of soybean. Sci. Sucrose is metabolised by sucrose synthase and glycolysis within the phloem complex of Ricinus communis L. seedlings. The hexoses can be phosphorylated to hexose phosphates (hex-P), directed to starch synthesis in the plastid or to glycolysis and then respiration in the mitochondria or directed to other metabolic pathways.

Other studies have produced somewhat contradictory evidence for the role of SuSy in sink strength. Sucrose synthase of Arabidopsis: genomic cloning and sequence characterization. There is a lot of evidence that SUS are highly expressed in vascular tissues. Biochim. 49, 810–828. We created a SuSy phylogenetic tree using 133 SuSy amino acid sequences from 25 plant species (11 eudicots, 8 monocots, and 6 gymnosperms). The localization of SuSy to mitochondria and its possible interaction with a high voltage-dependent anion channel suggest that these SuSy may play a role in regulating solute fluxes between the mitochondria and the cytosol (Subbaiah et al., 2006). Each clade is divided into two sub-clades: monocots (marked with red arcs) and eudicots (marked with turquoise arcs). Equip. Planta 209, 13–24. Sucrose synthase may also play other important roles, in addition to its role in Suc cleavage. Science 339, 704–707. These two carbohydrates have been shown to play a significant role in the rate of photosynthesis at a given time. Rev. The first evidence of non-cytosolic SuSy was found in cotton (Gossypium hirsutum) fibers, in which 50% or more of the SuSy protein was found to be tightly associated with the plasma membrane (Amor et al., 1995). Crop Sci. Integration of light and metabolic signals for stem cell activation at the shoot apical meristem. The second site is also a serine, at around position 170, and is thought to regulate protein degradation (Hardin et al., 2003). It is more likely that SuSy are interacting with other proteins and form a complex that is also associated with the cellulose synthases or callose synthases located to membranes (Persia et al., 2008; Fujii et al., 2010).

Quaternary structure of sucrose synthetase from banana fruits. It can then enter the sink cells via Suc transporters or hydrolyzed by cell-wall invertase (cwINV) to yield glucose (Glc) and fructose (Fru), which can enter the sink cells via hexose transporters (Ruan, 2014). In transgenic tomato plant with antisense suppression of SUS, reduced Suc import was observed only in very young fruits (7 days after anthesis) and not during the later starch-accumulation phase (23 DAA; D’Aoust et al., 1999). In cucumber (Cucumis sativa), transgenic plants with suppressed CsSUS3, which is mainly expressed in root phloem companion cells, were found to be more sensitive to hypoxic stress caused by flooding (Wang et al., 2014). (1999). Plant Mol. Sci. The role of sugars as signaling molecules in the SAM is a subject of lively debate and it is not always easy to differentiate between their signaling function and their metabolic role. Front.

That is, in case of excess cleavage of Suc by SuSy, the increased fructose Fru inhibits fructokinase activity so that fructose accumulates and that accumulated Fru inhibits further cleavage of Suc by SuSy. Structure, expression profile, and evolution of the sucrose synthase gene family in peach (Prunus persica). This fact, the greater activity of SuSy, as compared with AGPase, in barley seeds, and the reduced levels of ADP-G observed in potato tubers with repressed SUS together suggest that Suc cleavage by SuSy directly supplies ADP-G for starch synthesis (Baroja-Fernandez et al., 2003). Plant Physiol. Planta 217, 628–638. This review summarizes the current knowledge regarding plant SuSy, including newly discovered possible developmental roles for SuSy in meristem functioning that involve sugar and hormonal signaling. In the cytosol, Suc can be hydrolyzed by cytosolic INV to yield Glc and Fru, or cleaved by cytosolic SuSy to yield Fru and UDP-G. Structure and expression analysis of the sucrose synthase gene family in apple. Inside the cell, Suc can be stored in the vacuole or hydrolyzed by vINV. Proc. 121, 599–608. Phloem loading is thought to be highly important for defining sink strength and the breakdown of Suc in sink organs may also contribute to sink strength. On the other hand, Amor et al. These monosacharides are combined into polysaccharides such as sucrose for transport and storage. For example, a reduction in SuSy activity reduced starch content in potato tubers, carrot taproots and maize endosperm (Chourey and Nelson, 1976; Zrenner et al., 1995; Tang and Sturm, 1999). doi: 10.1104/pp.104.2.535, Wang, H.

Since then, many other SUS genes have been cloned from different plants, including another maize SUS (McCarty et al., 1986; Shaw et al., 1994) and genes from Arabidopsis (Chopra et al., 1992; Martin et al., 1993), rice (Wang et al., 1992; Yu et al., 1992), potato (Solanum tuberosum) (Fu et al., 1991; Fu and Park, 1995) and tomato (Solanum lycopersicum) (Goren et al., 2011). Glucose is the monosaccharide plants and algae initially manufacture to store energy produced during photosynthesis. sugar+oxygen. The transgenic plants overexpressing AtSUS1 showed increased chlorophyll levels, as well as increased photosynthesis, TSS (total soluble sugars), starch, Suc and Fru, as well as increased enzymatic activity of SPS and SPP in leaves, indicating increased sugar production in the transgenic plants. doi: 10.1104/pp.120.4.1105, Cai, G., Faleri, C., Del Casino, C., Emons, A. M., and Cresti, M. (2011). 45, S151–S151. 116, 1323–1331. To summarize, plant SuSy activity has been shown to play important roles in plant sugar metabolism, primarily in sink tissues. Plant physiologists and biochemists have tried to find the first product of this process. 134, 1146–1152. Phytochemistry 57, 823–833. Other SuSy isoforms are much smaller, for example, the bird cherry SuSy monomers are estimated to be about 53, 58, and 63 kDa (Sytykiewicz et al., 2008).

Plasma membrane associated SuSy (pmSuSy) and cwSUS can generate UDP-G that is used in the synthesis of cellulose for cell walls and callose for plugging plasmodesmata. 252, 303–310. Interestingly, transgenic plants of a commercial rice cultivar expressing SUS3 showed a decreased percentage of chalky grains under heat stress only when both the promoter and the cDNA of the heat-tolerant allele were introduced, indicating not only the importance of the SUS3 protein, but also the response rate to heat stress in terms of gene expression (Takehara et al., 2018). 9, 100–101. Biochem. The spatial distribution of sucrose synthase isozymes in barley. Because Suc cleavage by SuSy yields UDP-G, which is a direct substrate for both cellulose (β1-4) and callose (β1-3) glucans, it is widely assumed that SuSy plays a role in the synthesis of both of these polysaccharides. Funct. Harada, T., Satoh, S., Yoshioka, T., and Ishizawa, K. (2005). SuSy proteins are usually homotetramers with an average monomeric molecular weight of about 90 kD (about 800 amino acids long). “Cellulose biosynthesis in developing cotton fibers,” in Cotton Fibres: Developmental Biology, Quality Improvement, and Textile Processing, ed. However, SuSy appear to localize to the phloem not only in the Suc unloading zones, but also in loading zones in mature leaves of citrus, maize, rice, Arabidopsis, and poplar (Nolte and Koch, 1993; Regmi et al., 2016), which suggests that SuSy probably play a general role in the phloem that is not limited to phloem unloading. Strawberry fruits with RNAi suppression of FaSUS1 by virus-induced gene-silencing exhibited delayed fruit ripening, maintained their firmness and exhibited delayed anthocyanin accumulation (Zhao et al., 2017).

In plant photosynthesis, carbon dioxide is fixed in the chloroplasts via the Calvin cycle to yield triose phosphates (triose-P). Overexpression of SUS in potato tubers increased UDP-G and ADP-G levels and increased starch accumulation and yield (Baroja-Fernandez et al., 2009). A study of potato tubers of transgenic plants overexpressing INV or Suc pyrophosphorylase, which allows a way to bypass the degradation of Suc by SuSy, revealed a steeper reduction in oxygen levels inside the tubers, reduced starch synthesis and a lower ATP to ADP ratio, underscoring the importance of SuSy under low-oxygen conditions (Bologa et al., 2003). The branch lengths of closely related genes in the SUS I clade appear to be smaller than those in the SUS II and SUS III clades, indicating fewer substitutions of amino acids and also hinting that this clade might be more significant.

In situ hybridization also revealed the presence of SUS transcript in young maize leaf primordia, suggesting a role for SuSy in early leaf development (Hanggi and Fleming, 2001). Oxygen is the final acceptor in the mitochondrial electron transport chain and the absence of oxygen blocks electron transfer and cellular ATP production. doi: 10.1023/A:1006327606696, Tong, X.
