Summary - An increasing number of plant scientists, including breeders, agronomists, physiolo-gists and molecular biologists, are working towards the development of new andimproved energy crops. Research is increasingly focused on how to design crops spe-cifically for bioenergy production and increased biomass generation for biofuel pur-poses. The most important biofuel to date is bioethanol produced from sugars(sucrose and starch). Second generation bioethanol is also being targeted for studiesto allow the use of the cell wall (lignocellulose) as a source of carbon. If a crop is tobe used for bioenergy production, the crop should be high yielding, fast growing,low lignin content and requiring relatively small energy inputs for its growth andharvest. Obtaining high yields in nonprime agricultural land is a key for energy cropdevelopment to allow sustainability and avoid competition with food production.Sugarcane is the most efficient bioenergy crop of tropical and subtropical regions,and biotechnological tools for the improvement of this crop are advancing rapidly. We focus this review on the studies of sugarcane genes associated with sucroseKeywords: sugarcane, biomass, bio- content, biomass and cell wall metabolism and the preliminary physiologicalenergy, genes, yield, expression. characterization of cultivars that contrast for sugar and biomass yield.
