Diversification of Two Lineages of Symbiotic Photobacterium
Understanding of processes driving bacterial speciation requires examination of closely related, recently diversified lineages. To gain an insight into diversification of bacteria, we conducted comparative genomic analysis of two lineages of bioluminescent symbionts, Photobacterium leiognathi and 'P. mandapamensis'. The two lineages are evolutionary and ecologically closely related. Based on th...
متن کاملN-Acetyl Glucosamine Obtained from Chitin by Chitin Degrading Factors in Chitinbacter tainanesis
A novel chitin-degrading aerobe, Chitinibacter tainanensis, was isolated from a soil sample from southern Taiwan, and was proved to produce N-acetyl glucosamine (NAG). Chitin degrading factors (CDFs) were proposed to be the critical factors to degrade chitin in this work. When C. tainanensis was incubated with chitin, CDFs were induced and chitin was converted to NAG. CDFs were found to be loca...
متن کاملDating the Diversification of the Major Lineages of Ascomycota (Fungi)
Establishing the dates for the origin and main diversification events in the phylogeny of Ascomycota is among the most crucial remaining goals in understanding the evolution of Fungi. There have been several analyses of divergence times in the fungal tree of life in the last two decades, but most have yielded contrasting results for the origin of the major lineages. Moreover, very few studies h...
متن کاملEcological opportunity and the adaptive diversification of lineages
The tenet that ecological opportunity drives adaptive diversification has been central to theories of speciation since Darwin, yet no widely accepted definition or mechanistic framework for the concept currently exists. We propose a definition for ecological opportunity that provides an explicit mechanism for its action. In our formulation, ecological opportunity refers to environmental conditi...
متن کاملThe Diversification of Zika Virus: Are There Two Distinct Lineages?
Zika virus (ZIKV) has caused explosive epidemics in the Pacific and the Americas, posing a serious threat to public health. Conventional opinion advocates that ZIKV evolved into two distinct lineages, namely, African and Asian. Descendants of this latter lineage dispersed globally causing major epidemics. However, based on shared amino acid replacements and phylogenetic analyses, it was recentl...
