“…In Arabidopsis, six SUS genes have been characterized (Baud et al, 2004), similarly, six SUS genes have been identified in each of the following species: rice (Hirose et al, 2008), tomato (Goren et al, 2017), rubber tree ( Hevea brasiliensis ) (Xiao et al, 2014), cacao ( Theobroma cacao L.) (Li et al, 2015), peach ( Prunus persica ) (Zhang et al, 2015) and Nicotiana sylvestris (Wang et al, 2015). Seven SUS genes have been identified in cotton ( Gossypium arboreum ) (Chen et al, 2012), bamboo ( Bambusa emeiensis ) (Huang et al, 2018) and Nicotiana tomentosiformis (Chen et al, 2012; Wang et al, 2015; Huang et al, 2018). Only five genes have been characterized in grape ( Vitis vinifera ) and sugarcane ( Saccharum spp.…”

“…Phylogenetic tree of SUS genes from land plants. SuSy amino acid sequences were obtained from PUBMED using gene or protein IDs from previous studies (Baud et al, 2004; Hirose et al, 2008; Chen et al, 2012; Xiao et al, 2014; Zhang et al, 2015; Zhu et al, 2017; Abdullah et al, 2018; Huang et al, 2018; Tong et al, 2018). Additional amino acid sequences were retrieved using the Plaza 3.0 tool for gene-family analysis (Van Bel et al, 2017) using “sucrose synthase” in a keyword search.…”

An Overview of Sucrose Synthases in Plants

Sucrose is the end product of photosynthesis and the primary sugar transported in the phloem of most plants. Sucrose synthase (SuSy) is a glycosyl transferase enzyme that plays a key role in sugar metabolism, primarily in sink tissues. SuSy catalyzes the reversible cleavage of sucrose into fructose and either uridine diphosphate glucose (UDP-G) or adenosine diphosphate glucose (ADP-G). The products of sucrose cleavage by SuSy are available for many metabolic pathways, such as energy production, primary-metabolite production, and the synthesis of complex carbohydrates. SuSy proteins are usually homotetramers with an average monomeric molecular weight of about 90 kD (about 800 amino acids long). Plant SuSy isozymes are mainly located in the cytosol or adjacent to plasma membrane, but some SuSy proteins are found in the cell wall, vacuoles, and mitochondria. Plant SUS gene families are usually small, containing between four to seven genes, with distinct exon-intron structures. Plant SUS genes are divided into three separate clades, which are present in both monocots and dicots. A comprehensive phylogenetic analysis indicates that a first SUS duplication event may have occurred before the divergence of the gymnosperms and angiosperms and a second duplication event probably occurred in a common angiosperm ancestor, leading to the existence of all three clades in both monocots and dicots. Plants with reduced SuSy activity have been shown to have reduced growth, reduced starch, cellulose or callose synthesis, reduced tolerance to anaerobic-stress conditions and altered shoot apical meristem function and leaf morphology. Plants overexpressing SUS have shown increased growth, increased xylem area and xylem cell-wall width, and increased cellulose and starch contents, making SUS high-potential candidate genes for the improvement of agricultural traits in crop plants. 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 temperate grassland ecosystems, grazing can affect plant growth by foraging, trampling, and excretion. The ability of dominant plant species to regrow after grazing is critical, since it allows the regeneration of photosynthetic tissues to support growth. We conducted a field experiment to evaluate the effects of different grazing intensities (control, light, medium, and heavy) on the physiological and biochemical responses of Leymus chinensis and the carbon (C) sources utilized during regrowth. Light grazing promoted regrowth and photoassimilate storage of L. chinensis, by increasing the net photosynthetic rate (Pn), photosynthetic quenching, light interception, sugar accumulation, sucrose synthase activities, and fructose supply from stems. At medium grazing intensity, L. chinensis had low Pn, light interception, and sugar accumulation, but higher expression of a sucrose transporter gene (LcSUT1) and water‐use efficiency, which reflected a tendency to store C in belowground to promote survival. This strategy was associated with regulation by abscisic acid (ABA), jasmonate, and salicylic acid (SA) signaling. However, L. chinensis tolerated heavy grazing by increased ABA and jasmonate‐induced promotion of C assimilation and osmotic adjustment, combined with photoprotection against photo‐oxidation, suggesting a strategy based on regrowth. In addition, stems were the main C source organs and energy supply rather than roots. Simultaneously, SA represented a weaker defense than ABA and jasmonate. Therefore, L. chinensis adopted different strategies for regrowth under different grazing intensities, and light grazing promoted regrowth the most. Our results demonstrate the regulation of C reserves utilization by phytohormones, and this regulation provides an explanation for recent results about grazing responses.
