Function
In rice three genes encoding for sucrose synthase (Sus),six genes comprise the entire rice Sus gene family.The six SUS genes can be classified into three recognized Sus groups, the Sus1 group (SUS1, 2and3),the SusA group (SUS4) and the NG (SUS5 and 6),
It has been reported that sugar metabolism of rice seedlings is affected by hypoxia typically caused by submergence, and that Sus activity is suggested to be one of the key factors for the altered sugar metabolism in rice plants under submerged condition. overall Sus activity and expression of SUS2 increased significantly in seedlings germinated and grown in hypoxia (submerged conditions), suggesting a role in increasing sucrose metabolism as a response to environmental stress.Sucrose is cleaved in vivo either by sucrose synthase (Sus) (UDP-glucose: D-fructose 2-glucosyl-transferase, EC 2.4.1.13) or by invertase. Sus catalyzes the reversible conversion of sucrose and UDP into UDP-glucose and fructose. There is considerable evidence to indicate that Sus plays a major role(s) in metabolism in a number of different growth processes within a variety of sink tissues.Sus is also proposed to supply UDP-glucose for cellulose synthesis in the cell wall, and in cotton fiber which is supported by experimental evidence from antisense suppression of the enzyme.[1]
Recently a growing body of evidence suggests that one of the major roles of Sus is to channel UDP-glucose to the synthesis of cell-wall polysaccharides such as cellulose[2]
Expression
Sus transcripts were detected in a wide range of tissues and at different developmental stages, indicating that Sus is involved in numerous and diverse growth processes in the rice plant. SUS2 was shown to be expressed in a wide range of tissues, suggesting that it may perform a number of housekeeping role(s)[3]
Sus gene expression has also been reported to be induced in response to environmental stresses such as hypoxia and cold. Sus is reported to be encoded by multiple genes which have distinct and partially overlapping expression patterns. For example, maize has at least three genes encoding Sus, Sh1, Sus1 and Sus3 .
The mRNA levels for the SUS genes were highest in elongating sink organs such as roots, developing leaf blades and elongating uppermost internodes, with SUS1 and 2 being the isoforms predominantly expressed within these tissues. In contrast to this, SUS transcript levels in the mature leaf blades and leaf sheaths were low. The transcript levels of each SUS gene were plotted individually to examine specific expression patterns (Figure 1).SUS2 transcript levels were higher in root and internode tissue than other tissues examined.In all of the internode segments the transcripts of SUS1 and SUS2 together accounted for most of the SUS transcripts, and the transcript levels of the other four SUS genes were either negligible or not detected. SUS2 was most highly expressed in the bottom segment and decreased in subsequent segments before a slight increase in the top two segments.Overall SUS2 expression levels were considerably lower than those for SUS1. SUS1 mRNA was most abundantly expressed in the early stage of the grain filling, at 1–3 DAF, and gradually decreased thereafter. The transcript level of SUS2 was at similar levels to those of SUS1 at 1 and 2 DAF, then increased and reached maximal levels during 5–10 DAF, and decreased thereafter.[3]
Evolution
the evolution of multiple SS genes is not for the need of diversified catalytic functions but to meet the differential temporal and spatial requirements of the catalytic functiong according to the scheme of plant development and in response to environmental changes.this trend may be especially enhanced in the rice where the plant must adapt to the aerobic( leaf,stem,and grain) and anaerobic (root) conditions simultaneously and accumulate starch in a short period of the life span.[1]
