    Giant viruses, despite not being defined as 'life', possess large number of genes. Previous research has confirmed that marine giant viruses tend to be endemic, which inspires me to work on the environmental adaptation of giant viruses. In this study, it is suggested that giant viruses have adapted to polar environments through changes in their gene repertoire, and their adaptation mechanism may differ from others. However, current research remains at the hypothetical stage, and especially since there are many unexplained genes in viruses, a definitive virus adaptation mechanism has not been identified.

    3. Most of double stranded DNA viruses are classified into one of two realms: Varidnaviria, which includes giant viruses, and Duplodnaviria, which includes herpesviruses causing diseases in animals. These two realms have been considered evolutionarily unrelated. However, the newly discovered mirusviruses possess features of both realms. Genes of “informational module” for genome replication and gene expression were similar to those of Varidnaviria, while genes of “virion module” that encode structural proteins were similar to those of Duplodnavira. This mosaic feature of mirusviruses suggests that herpesviruses evolved from tailed bacterial viruses via ancestral protist-infecting viruses, namely the ancestors of the modern day mirusviruses and herpesviruses. Furthermore, gene transfers of “informational genes” between the two realms probably played crucial roles in their evolution. Mirusviruses appear to be prevalent and abundant in the sea and likely infect a variety of protists. However, they were discovered by bioinformatics analyses of marine metagenomic data, and there are currently no cultured viruses from this group of viruses.

    5. Quorum sensing is a communication system used by bacteria that depends on their population density and involves signaling molecules called autoinducers (AI). Autoinducer-2 (AI-2), produced by the LuxS enzyme, is known to facilitate interspecies communication. In Aeromonas salmonicida, a pathogen affecting cold-water fish, the role of AI-2 and LuxS is not well understood. This study aimed to explore LuxS's function in A. salmonicida. The findings revealed that wild-type A. salmonicida produces AI-2, while a luxS mutant does not. LuxS deficiency was linked to changes in bacterial morphology, surface properties, and virulence. Additionally, when salmon were infected with the luxS mutant, immune responses were triggered earlier. The study hypothesizes that AI-2 quorum sensing may regulate the expression of the A-layer protein gene vapA, influencing bacterial survival under immune attack.
