Early and late gene expression in pepper huasteco yellow vein virus.

A Germin-Like Protein Gene (CchGLP) of Capsicum chinense Jacq. Is Induced during Incompatible Interactions and Displays Mn-Superoxide Dismutase Activity

A germin-like gene (CchGLP) cloned from geminivirus-resistant pepper (Capsicum chinense Jacq. Line BG-3821) was characterized and the enzymatic activity of the expressed protein analyzed. The predicted protein consists of 203 amino acids, similar to other germin-like proteins. A highly conserved cupin domain and typical germin boxes, one of them containing three histidines and one glutamate, ar...

The effect of ecosystem biodiversity on virus genetic diversity depends on virus species: A study of chiltepin-infecting begomoviruses in Mexico

Current declines in biodiversity put at risk ecosystem services that are fundamental for human welfare. Increasing evidence indicates that one such service is the ability to reduce virus emergence. It has been proposed that the reduction of virus emergence occurs at two levels: through a reduction of virus prevalence/transmission and, as a result of these epidemiological changes, through a limi...

Cloning and Expression of the Coat Protein Gene of Barley Yellow Dwarf Virus-PAV in Escherichia coli

Nucleo-cytoplasmic shuttling of the beet necrotic yellow vein virus RNA-3-encoded p25 protein.

The protein p25 encoded by beet necrotic yellow vein virus (BNYVV) RNA-3 is involved in symptom expression of infected plants. Confocal microscopy analysis of wild-type and mutated p25 fused to GFP and transiently expressed in BY-2 tobacco suspension cells identified a nuclear localization signal (NLS) in the N-terminal part of the protein. Functionality of the NLS was confirmed by pull-down as...

Anti-viral Effect and Mechanism of Carvacrol on Herpes Simplex Virus Type 1

Background and Aims: Herpes simplex virus type 1 (HSV-1) belonging to herpes viridae family is a normal human pathogen with benign lesions in immunocompromised patients which creates serious problems. Acyclovir is used to treat herpetic infections. Because of developing drug-resistant strains, the use of medicinal plants and their related compounds with fewer side effects is considered for the ...
