Última Molecular evolution of the ent-kaurenoic acid oxidase gene in Oryzeae Genet. Mol. Biol. Yang,Yanhua; Chen,Keping. We surveyed the substitution patterns in the ent-kaurenoic acid oxidase (KAO) gene in 11 species of Oryzeae with an outgroup in the Ehrhartoidaea. The synonymous and non-synonymous substitution rates showed a high positive correlation with each other, but were negatively correlated with codon usage bias and GC content at third codon positions. The substitution rate was heterogenous among lineages. Likelihood-ratio tests showed that the non-synonymous/synonymous rate ratio changed significantly among lineages. Site-specific models provided no evidence for positive selection of particular amino acid sites in any codon of the KAO gene. This finding suggested that the significant rate heterogeneity among some lineages may have been caused by variability in the...

Hajjari,Mohammadreza; Saffar,Behnaz; Khoshnevisan,Atefeh. Codon usage bias has been observed in various organisms. In this study, the correlation between SHH genes expression in some tissues and codon usage features was analyzed by bioinformatics. We found that translational selection may act on compositional features of this set of genes.

Ano: 2010 URL: http://www.scielo.br/scielo.php?script=sci_arttext&pid=S1415-47572010000200033 Three tubulin genes of Trichoderma harzianum: alpha, beta and gamma BABT Li,Min; Yang,Qian; Song,Jinzhu. Three tubulin genes of Trichoderma harzianum were cloned followed genomic walking procedure. The tubulins showed high degree of amino acid homology with other fungal tubulins and were homologous with each other with 32 to 38% amino acid identity. Three measures for the degree of codon usage bias indicated the presence of bias in all the sequences, suggesting high expression levels in all the genes. Protein structures were modeled to provide the basis for understanding the tubulin's properties and its interactions with microtubule-associated proteins. Potential motifs were also postulated.
