Dalechampia chlorotic mosaic virus (DCMV) is a plant virus that primarily affects species within the genus Dalechampia, particularly Dalechampia spp., which are flowering plants in the family Euphorbiaceae. DCMV is a member of the genus Potyvirus within the family Potyviridae. This virus is known for causing symptoms of chlorotic mosaic, leaf mottling, and stunting in infected plants.

(a) 10 min pi, virions have been engulfed and are in vacuoles. (b) 20 min pi, virions in vacuoles exhibit holes (black arrows) in their external translucent shell and appear more spherical. (c) 30 min pi, virions have entirely lost their external shell and appear as spherical electron-dense nucleoids, which can be seen in vacuoles as well as in the cell cytoplasm (and Fig. 9, black arrows). Scale bar, 100 nm. (d) 1 h pi, electron-dense tubular structures (black arrowheads) appear in the cytoplasm. (e) 4 h pi viral factories (VF) settle in the cell cytoplasm next to the nucleus and the cell organelles are pushed at their periphery (scale bar, 2 μm). The new virions are assembled and the electron-dense mature (white arrows) and immature (white arrowheads) virions are scattered in the same VF. Inset: immature and mature virions inside the VF along with tubular structures (black arrowheads). Scale bar, 200 nm. (f) 7 h pi, the newly synthesized virions are gathered into vacuoles inside the cytoplasm before being released in the extracellular environment (scale bar, 500 nm) [1].

Space-fill drawing of the Zika virus capsid, with the capsid proteins in shades of yellow and orange to show the icosahedral symmetry. The membrane proteins in the under layer (magenta) show through in some places, and the cyan protrusions are attached carbohydrate chains. Drawn by David Goodsell from the cryoEM structure 5ire.

Birch leaf roll-associated virus (BLRaV) is a plant virus that primarily infects birch trees (Betula spp.). It belongs to the family Betaflexiviridae and the genus Capillovirus. BLRaV is associated with a disorder known as birch leaf roll, characterized by the rolling or curling of leaves, leaf discoloration, and reduced vigor in infected trees.

Dinocampus coccinellae paralysis virus (DcPV) is a virus that infects parasitoid wasps of the species Dinocampus coccinellae, which parasitize ladybird beetles (coccinellids). The primary host of DcPV is the parasitoid wasp Dinocampus coccinellae, which lays its eggs inside ladybird beetle larvae. The virus infects the wasp's reproductive tissues and is transmitted to the ladybird beetle host during oviposition. Once inside the beetle larva, the virus establishes infection and may cause paralysis or other physiological effects.

Phylogenetic analysis of hemagglutinin (HA) genes nucleotide sequences from 57 Equine Influenza Viruses (EIVs). The maximum likelihood tree was constructed using stringent T92 + G algorithm which was identified using the find best DNA/protein model tool available in MEGA 6. The reliability of the trees was assessed by bootstrap with 1,000 replications with cut off at 50 are shown in the tree. The phylogram depicts five major clusters of global EIVs. Phylogenetic group's viz., Florida sub-lineage clade 1, Florida sub-lineage clade 2, American, Eurasian and Pre-divergent, are mentioned by bars on the right. The major mutations (I179V and A144V) observed in the Clade 2 viruses of Florida sublineage in recent isolates have been denoted by solid dots. [1]
