ResumoTranscription factors are essential in plant growth and development regulation and during response activation to environmental stimuli. This study examined 237,954 sugarcane and 110,000 eucalyptus ESTs in search of genes related to MYB factors active during abiotic stresses in arabidopsis and rice. Searches revealed relative abundance and diversity of MYB candidate sequences in both transcriptomes. In general, 71 and 42 MYB sequences have been selected in eucalyptus and sugarcane, respectively. The generated phenogram, using selected sequences and sequences from other organisms, revealed a sub-grouping according to domain-repeats number; confirming the ancestral origin of MYB genes. Expression pattern analysis revealed higher number of reads in wood, flower and bark libraries in eucalyptus, and in tissues infected by pathogens in sugarcane. Splicing pattern comparative analyses of arabidopsis and rice ORFs with eucalyptus and sugarcane ORFs revealed that neither of them presented similarities regarding all exons and intron junctions.
