Impact of Wheat Streak Mosaic Virus on Peroxisome Proliferation, Redox Reactions, and Resistance Responses in Wheat.

Although peroxisomes play an essential role in viral pathogenesis, and viruses are known to change peroxisome morphology, the role of genotype in the peroxisomal response to viruses remains poorly understood. Here, we analyzed the impact of wheat streak mosaic virus (WSMV) on the peroxisome proliferation in the context of pathogen response, redox homeostasis, and yield in two wheat cultivars, Patras and Pamir, in the field trials. We observed greater virus content and yield losses in Pamir than in Patras.

Phylogenetic relationships of two Ukrainian tomato isolates of potato virus M and genetic variability analysis of its population.

The aim of this study was to investigate biological and molecular properties of two Ukrainian tomato isolates of potato virus M (PVM), K-16 and Pol-14, to determine their phylogenetic relationships and the genetic variability of PVM isolates. Study of phylogenetic relationships of two Ukrainian tomato PVM isolates with 35 isolates represented in GenBank was conducted. It was found that the coat protein (CP) gene sequence identity between two Ukrainian PVM isolates is 94.
