Second, our results provide insight into the evolution of components of RI and their mechanisms, particularly in the context of the observed differences in patterns for habitat versus sexual isolation. Host preference and associated habitat isolation in phytophagous insects has played a particularly promi...
44,45. (1) Passive processes (‘diffusive’ evolution) imply that evolving lineages undergo random walks but the extent of decreases is limited by the existence of lower bounds, such as biomechanical or physiological
Definition Divergent evolution represents the evolutionary pattern in which species sharing a common ancestry become more distinct due to differential selection pressure which gradually leads to speciation over an evolutionary time period. Introduction ...
- 《Current Biology》 被引量: 113发表: 2001年 Novel KIR3DL1 alleles and their expression levels on NK cells: convergent evolution of KIR3DL1 phenotype variation? KIR3DL1 shows extensive polymorphism, and its variation has functional significance in terms of cell-surface expression levels and ...
Transitory starch metabolism is a nonlinear and highly regulated process. It originated very early in the evolution of chloroplast-containing cells and is largely based on a mosaic of genes derived from either the eukaryotic host cell or the prokaryotic endosymbiont. Initially located in the cytoplasm...
DNA-binding specificities were determined for 10 of the 17 expressed HSFs (Fig.2A). To help interpret their evolution, in the figure their DNA targets are overlaid on a phylogenetic tree based on the DNA-binding domains. Also shown are expression patterns of the TFs, presented in the same ...
The two fungal nodes that present the largest compositional shift towards Fungi-related functional categories are, on the one hand, the stem node of Dikarya (Ascomycota + Basidiomycota) (+1.9%; Fig.1d), which experienced genetic changes that could have predisposed the evolution of complex multicell...
