Plant viruses cause significant losses in agricultural crops worldwide, affecting the yield and
quality of agricultural products. The emergence of novel viruses or variants through genetic …

The frequency and global impact of infectious disease outbreaks, particularly those caused
by emerging viruses, demonstrate the need for a better understanding of how spatial …

RNA viruses are characterized by high genetic variability resulting in rapid adaptation to
new or resistant hosts. Research for plant RNA virus genetic structure and its variability has …

An appreciation of the risks caused by emergent plant viruses is critical in tropical areas that
rely heavily on agriculture for subsistence and rural livelihood. Molecular ecology, within 10 …

The nonexpressor of pathogenesis-related (PR) genes (NPR1) protein plays an important
role in mediating defense responses activated by pathogens in Arabidopsis. In rice, a …

Tomato yellow leaf curl disease (TYLCD)-associated viruses present a highly structured
population in the western Mediterranean basin, depending on host, geographical region …

Africa produces only 2.7% of the world's rice and is the second-largest riceimporting region
in the world (6.5 Mt in 2003). This amount represents about 25% of the world rice importation …

Cassava is infected by numerous geminiviruses in Africa and India that cause devastating
losses to poor farmers. We here describe the molecular diversity of seven representative …

Plant viruses, as obligate intracellular parasites, induce significant changes in the cellular
physiology of host cells to facilitate their multiplication. These alterations often lead to the …

Recent studies in plant virus evolution are revealing that genetic structure and behavior of
virus and viroid populations can explain important pathogenic properties of these agents …
