Metagenomics of plant and fungal viruses reveals an abundance of persistent lifestyles

INTRODUCTION Most studies of plant viruses have focused on the acute viruses that cause disease in crop and ornamental plants. These viruses are transmitted horizontally, often by insect vectors, and are occasionally transmitted vertically. Although known for at least four decades, the persistent viruses of plants are very poorly studied. These viruses were previously called “cryptic” because t...

Transposons and their application in plant pathology

Prokaryote, viruses, and eukaryotes chromosomes contain fragments of DNA can move and migrate to other parts of the chromosome calling as Transposition and play an important role in new combinations of gene production. DNA fragments carrier the genes or transposons are the transposable elements that may called gene mutant also. Transposons can move to another position of the same chromosome or ...

Virus Evolution: Fitting Lifestyles to a T

The structure of a double-stranded RNA virus outer shell has revealed unexpected similarities with virions of positive-strand RNA viruses. These similarities intersect with emerging parallels in RNA replication to create intriguing evolutionary possibilities.

Secret lifestyles of Neurospora crassa

Neurospora crassa has a long history as an excellent model for genetic, cellular, and biochemical research. Although this fungus is known as a saprotroph, it normally appears on burned vegetations or trees after forest fires. However, due to a lack of experimental evidence, the nature of its association with living plants remains enigmatic. Here we report that Scots pine (Pinus sylvestris) is a...
