Evolution and expression of the fructokinase gene family in Saccharum.

ABSTRACT:

Background

Sugarcane is an important sugar crop contributing up to about 80% of the world sugar production. Efforts to characterize the genes involved in sugar metabolism at the molecular level are growing since increasing sugar content is a major goal in the breeding of new sugarcane varieties. Fructokinases (FRK) are the main fructose phosphorylating enzymes with high substrate specificity and affinity.

Results

In this study, by combining comparative genomics approaches with BAC resources, seven fructokinase genes were identified in S. spontaneum. Phylogenetic analysis based on representative monocotyledon and dicotyledon plant species suggested that the FRK gene family is ancient and its evolutionary history can be traced in duplicated descending order: SsFRK4, SsFRK6/SsF
