Research that began with a study of replication enzymes used by bacteria has led to a controversial theory: Viruses may have helped shape all three major domains of life 
Origins of Life, RNA World or Alternative RNA World
Why and how our living-bodies, such as human beings, have originated from a barely non-life planet into the highly-intelligent life existing Earth, and have been interested and pursued by largeExpand
Impact of RNA Virus Infection on Plant Cell Function and Evolution
Tobacco mosaic virus encodes replicase proteins and coat protein, to replicate and protect the RNA genome, and a movement protein that binds viral RNA and manipulates the size exclusion limit of plasmodesmata to facilitate the spread of the viral genomic RNA. Expand
Introduction: The Emergence of Pathogenic Viruses
Many of the experiences faced in the 20th century with viruses such as human immunodeficiency virus and human T-lymphotropic virus provide models for developing programs to monitor and counteract emerging viruses in the 21st century. Expand
Living strategies of unusual life forms on Earth and the relevance to astrobiology
Viruses and nanobacteria challenge the current definitions of life, but they are considered here as life forms that seem to be well suited for the life on Mars or other extraterrestrial environments that are harsh. Expand
Viruses and sumoylation: recent highlights
Since its discovery in 1997, SUMO has been implicated in a range of activities, indicating that this protein is as important in the cell as ubiquitin is, and it is important to understand how viruses manipulate the cellular sumoylation system and howsumoylation affects viral functions. Expand
Deep-sea thermophilic Geobacillus bacteriophage GVE2 transcriptional profile and proteomic characterization of virions
Transcriptional analyses and proteomic characterization of GVE2 would be helpful to understand the complex host–virus interaction during virus infection. Expand
First Genetic Information Replication in Life Origin on Earth
One of the crucial factors for evolution, formation rate or turnover speeds of different genetic materials (DNA, RNA and protein), to further suggest an important role RNA may take in life origin on Earth is discussed. Expand
Extrachromosomal element capture and the evolution of multiple replication origins in archaeal chromosomes
It is demonstrated that Aeropyrum pernix, a distant relative of Sulfolobus, has two origins, providing evidence that horizontal gene transfer, in addition to its well-established role in contributing to the information content of chromosomes, may fundamentally alter the manner in which the host chromosome is replicated. Expand
Origins of Life, A New Cooperative Model
A new cooperative model of most genetic materials participation system is suggested based on the new systematic and logic deduction of life origin theories. Expand
The evolution of proteome: From the primeval to the very dawn of LUCA
This work portrays a step-wise proteome evolution, by looking at the phenotype encoded by each one of the genetic codes that were appearing along evolution, beginning with the primeval genetic code and then with two intermediate Extended RNA codes, which finally shaped the current Standard Genetic Code (SGC).
