Our finding that P. infestans secretes PLD activity in the medium suggests that Phytophthora exploits PLDs to modify host tissues and as such, PLDs may function in pathogenicity.
The Fic domain has been shown to covalently modify host Rho GTPases with AMP, which may explain how the Fic domain influences bacterial virulence [ 28].
Trait-mediated interactions may be particularly relevant in parasite host systems because parasites frequently modify host behaviour or physiology [ 6, 7] and have been implicated as drivers behind a range of biological invasions, including wild oat (Avena fatua) in California, fire ants (Solenopsis invicta) in North America and amphipod crustaceans (Gammarus) in UK freshwaters [ 6, 8].
Integrated viral DNA sequences might act in cis to modify host gene expression or encode viral proteins that may interfere with normal cellular functions either directly or indirectly.
The fic domain of VopS was shown to covalently modify host Rho GTPases with AMP.
Adaptation did not modify host ranking, as all lines performed best on the ancestral host.
Therefore, a stronger inflammatory response by the host may modify gastric cancer risk.
Intronic CGIs may modify expression of the host gene, harbor an alternative start site, belong to a gene that is located within an intron of the host gene, or may have no function at all.
A precore stop codon mutation (1896G to A) [ 15] and two mutations within the core promoter region (1762A to T and 1764G to A) [ 16, 17] have been associated with fulminant hepatitis B. Both variants show a defect in hepatitis e antigen (HBeAg) expression [ 18, 19], which may modify the immune response of the host [ 20, 21].
