Onset of flowering is critical to the plant reproductive success. In plants such as Arabidopsis thaliana, in which flowering is promoted under long days, inductive conditions lead to the production of FLOWERING LOCUS T ...
Viruses must attach to specific receptors on their host cells in order to initiate entry. Viral spread, tissue and host tropism are determined by precisely regulated contacts and affinities between viral proteins and their ...
Retrotransposons are mobile genetic elements, which replicate via a "copy-and-paste" mechanism, thereby creating a new copy of their DNA in the genome. LINE-1 (L1) is the most abundant retrotransposon in the human genome, ...
The signaling transduction proteins of PII superfamily are one of the ancient and highly conserved protein families in nature and widely distributed in all domains of life. Canonical PII exerts it’s signaling function via ...
Polyomaviruses are non-enveloped, double-stranded DNA viruses infecting animals, including mammals, birds, and fish. In immunocompromised individuals, certain polyomaviruses can inflict severe disease. In most cases, ...
On depletion of combined nitrogen, the filamentous cyanobacterium Anabaena sp. PCC 7120 forms N2-fixing heterocysts from vegetative cells. To protect the oxygen-sensitive nitrogenase, a heterocyst-specific layer composed ...
Antiviral cytotoxicity of lymphocytes such as natural killer (NK) cells, CD8 alpha-beta T cells and gamma-delta T cells is stimulated by the activating immunoreceptor NKG2D, which has the remarkable ability to engage at ...
