Catalysis of the transfer of a mannose residue to an oligosaccharide, forming a beta-(1->4) linkage.

Catalysis of the transfer of a mannosyl group to an acceptor molecule, typically another carbohydrate or a lipid.

OBSOLETE. Any process in which the symbiont regulates the increase in its size or mass within the cells or tissues of the host organism. This may (but not necessarily) include a filamentous growth form, and also can include secretion of proteases and lipases to break down. The host is defined as the larger of the organisms involved in the symbiotic interaction.

A process by which a viral gene is converted into a mature gene product or products (proteins or RNA). This includes viral transcription, processing to produce a mature RNA product, and viral translation.

A process by which viral mRNA is translated into viral protein, using the host cellular machinery.

Any protein maturation process achieved by the cleavage of a peptide bond or bonds within a viral protein.

The process by which a viral genome, or part of a viral genome, is transcribed within the host cell.

A large cytoplasmic membrane-bounded vesicle with an electron dense granular core, up to 150-200 nm in diameter, found in neurosecretory cells in the hypothalamus.

A cytoplasmic membrane-bounded vesicle of varying size, but usually larger than 45 nm, with an electron dense granular core, found in noradrenergic and peptidergic cells.

The viral transcription that takes place after early transcription in the viral life cycle, and which involves the transcription of genes required for replication.

Any apoptotic process in a retinal cell.

The first phase of viral transcription that occurs after entry of the virus into the host cell, but prior to viral genome replication. It involves the transcription of genes for non-structural proteins, and for lytic viruses, the early gene products are involved in establishing control over the host cell.

A cytoplasmic membrane-bounded vesicle first described in dendrites, categorized by smooth membranes, electron-lucent interiors and irregular shapes. Sometimes occurs in clumps. Amorphous vesicles have been found to contain material taken up from the extracellular space, therefore suggesting that they may be part of the endosomal pathway.

The transcription of the final group of viral genes of the viral life cycle, following middle transcription, or where middle transcription doesn't occur, following early transcription. Involves the transcription of genes encoding structural proteins.
