Evolutionary rate variation in anthocyanin pathway genes.
Over a broad taxonomic range that spans monocots and dicots, upstream enzymes of the anthocyanin pigment pathway have evolved less rapidly than downstream enzymes. In this article we show that this pattern is also evident within the genus Ipomoea. Specifically, the most upstream enzyme, chalcone synthase (CHS-D), evolves more slowly than the two most downstream enzymes, ancyocyanidin synthase (...
متن کاملRelaxed constraint and evolutionary rate variation between basic helix-loop-helix floral anthocyanin regulators in Ipomoea.
Regulatory genes are believed to play a large role in morphological diversification and are often characterized by elevated rates of evolution. Whether this rapid evolution is primarily due to adaptive differentiation or relaxed selective constraint remains an open question. We attempted to distinguish between these alternative outcomes in 2 transcription factors known to regulate the expressio...
متن کاملDetermining Difference in Evolutionary Variation of Bacterial RecA proteins vs 16SrRNA Genes by using 16s_Toxonomy Tree
Background and Aims: The rate of variation in various genes of a bacterial species is different during evolution. Therefore, in systematic bacterial studies many researchers compare the phylogenetic tree of a particular gene to the standard tree of an rRNA gene. Regarding the importance of 16SrRNA gene and the evolutional process of RecA protein family, we investigated the changes in the select...
متن کاملEvolutionary rate variation in Old World monkeys.
We analysed over 8 million base pairs of bacterial artificial chromosome-based sequence alignments of four Old World monkeys and the human genome. Our findings are as follows. (i) Genomic divergences among several Old World monkeys mirror those between well-studied hominoids. (ii) The X-chromosome evolves slower than autosomes, in accord with 'male-driven evolution'. However, the degree of male...
متن کاملThe causes of protein evolutionary rate variation.
The rate of protein evolution varies more than 1000-fold and, for the past 30 years, it was thought that the rate was determined by protein function. Drummond and co-workers have now shown that a single factor underlying mRNA expression, protein abundance and synonymous codon usage is the chief causal agent of protein evolutionary rate in yeast. It will be interesting to see whether this is sho...
