| To determine the phylogenetic relationship between sugarcane cultivars and other members of the Saccharinae subtribe, we identified the fast evolving ITS1-5.8S-ITS2 (ITS = internal transcribed spacer; 5.8S = 5.8S ribosomal DNA) region of the sugarcane genome in the Sugarcane Expressed Sequence Tag (SUCEST) genome project database. Parsimony analysis utilizing this region and homologs belonging to the 23 closely related Andropogoneae currently deposited in the GenBank database has shown sugarcane as the sister group of Saccharum sinense. However, because there are few parsimony-informative characters and high homoplasy in the ITS1-5.8S-ITS2 region we were not able to determine with confidence the phylogenetic relationship between sugarcane and some of the... |

| A set of genes related to secondary metabolism was extracted from the sugarcane expressed sequence tag (SUCEST) database and was used to investigate both the gene expression pattern of key enzymes regulating the main biosynthetic secondary metabolism pathways and the major classes of metabolites involved in the response of sugarcane to environmental and developmental cues. The SUCEST database was constructed with tissues in different physiological conditions which had been collected under varied situation of environmental stress. This database allows researchers to identify and characterize the expressed genes of a wide range of putative enzymes able to catalyze steps in the phenylpropanoid, isoprenoid and other pathways of the special metabolic mechanisms... |
