The SS genes performed a wide range of function in the plant species and expressed distinctly in different tissues. The SS genes also take part in starch storage in different crops organs like tubers, different root vegetables, kernels and pea embryos, import of sugar, response to different environmental stresses and also involved in nitrogen fixation, arbuscule maintenance and maturation in mycorrhizal legume roots. SS function normally suggested to use the UDP-glucose as substrate to synthesized the cellulose, that is vital for cell wall thickening and fiber cell development in cotton. SS family members also had vital metabolic function in plant growth and development processes. The sucrose and uridine diphosphate was used as precursor for SS to convert them into fructose and UDP-glucose and can also catalyze the reversible reaction.
Sucrose synthases or invertases were responsible for the cleavage of sucrose. Number of metabolic pathways start from the breakdown of sucrose within the plant tissues. Sucrose is the key photosynthesis product that used in the cellular metabolism of higher plants.

This study provides detailed genome-wide analysis of GmSS family in soybean that will provide new insights for future evolutionary and soybean breeding to improve the plant growth and development.Ĭitation: Ahmad MZ, Ahmad HI, Gul A, Shah Z, Ahmad B, Ahmed S, et al. The differential expression pattern was observed between the members of a paralogous.
Solexa sequencing libraries of acidic condition (pH 4.2) stress samples showed that the expression of class I GmSS genes increased 1- to 2-folds in treated samples than control. The expression of the class I members decreased during seed development, whireas, the class II members expression increased during the seed developing, may involve in sugar metabolism during seed development. All the GmSS family members except GmSS7 and few of class III members, were highly expressed in all the soybean tissues. The protein interaction of GmSS gave the co-expression of sucrose synthase with glucose-1-phosphate adenylyltransferase while SLAC and REL test found number of positive sites in the coding sequences of SS family members. The identified thirteen GmSS genes were divided into Class I, Class II and Class III with variable numbers of genes in each class. The segmental duplication was the major factor to increase the number of GmSS family members. High conserved regions were present in the GmSS sequences that may due to the selection pressure during evolutionary events.
In the present study, we found thirteen SS members (GmSS1-GmSS13) in G. In many plant species, the members of SS family have been investigated but the detailed information is not available in legumes particularly and Glycine max specifically. The sucrose synthase (SS) is an important enzyme family which play a vital role in sugar metabolism to improve the fruit quality of the plants.
