Comparative transcriptome of four species in Saccharum complex

Cultivars within the genus sugarcane have been backcrossed for a long time resulting in a narrow genetic background, cultivars deg-radation, and lack of resistance to biotic and abiotic stresses. Therefore, in sugarcane breeding, it is still a very important task to broaden the genetic base of sugarcane crops and improve stress re-sistance and biomass yield by using the gene pool of wild relatives.
