V iruses with single-stranded (ss)DNA genomes constitute a large class of economically, medically and ecologically important pathogens that infect hosts in all three domains of life1. Recent metagenomic studies have shown that these viruses are extremely widespread in various environments and are ...
divergence may have occurred after gene duplication, we compared the site-specific discrete model 3 that assumes two classes of sites with different v ratios and the clade model D that allows selective pressure at one class of sites (foreground clade) to be different from the rest of the ...

Biology and Evolution of Ferns and Lycophytes 2024 pdf epub mobi 电子书 图书描述 With their team of contemporary scholars, the editors present a thorough coverage of fundamental topics necessary for obtaining an up-to-date understanding of the biology of ferns and lycophytes. The book is organi...
InDrosophila, there is a higher proportion of highly constrained codons in essential genes than in any other dispensability class [58]. As hypothesized at the outset, stabilizing selection and the resulting sequence conservation may thus indicate functional importance of neuropeptides, signaling molecules...
The Class I cytokine receptors have a wide range of actions, including a major role in the development and function of immune and blood cells. However, the evolution of the genes encoding them remains poorly understood. To address this we have used bioin
THOMAS (Department of Plant Biology, North Carolina State University, Raleigh, NC 27695, USA) Abstract This study compares results on reconstructing the ancestral state of characters and ancestral areas of distribution in Cornaceae to gain insights into the impact of using different analytical methods...
The agl24svp double mutants reveal that SVP is epistatic to AGL24 in flowering time and show homeotic conversions in all floral whorls due to ectopic expression of class B and C organ identity genes (Gregis et al., 2006). SVP homologs have been primarily retained as single copy in other ...
Following the question wording used in the 2007 survey, we asked teachers to report on the number of class sessions they devote to "creationism or intelligent design."2 Table 3 shows that fewer teachers report discussing creationism and intel- ligent design in high school biology classes, down...
