Begomovirus Evolution and Disease Management

, 2006
Publisher Summary This chapter considers the knowledge of the roles of vector, viruses, and plant hosts in the emergence of begomovirus epidemics, and outlines areas in which further research is needed. It looks at the vector–virus–host interaction from an epidemiological and evolutionary perspective and considers how the understanding gained can be ...

Response of Various Tomato Genotypes to Begomovirus Infection and Its Improved Diagnostic

Hayati Journal of Biosciences, 2007
Begomovirus infection was identified from tomato growing areas in West Java (Bogor), Central Java (Boyolali), and D.I. Yogyakarta (Kaliurang). Efforts to reduce the infection among others are planting resistance varieties. This research was undertaken to

Insights Into Virus-Encoded RNA Silencing Suppressors Across Viral Families: A Focus on Viruses Infecting Solanaceae Crops. [PDF]

Physiol Plant
ABSTRACT Viral suppressors of RNA silencing (VSRs) are proteins that interfere with antiviral defense mechanisms and enhance infection. For plant viruses, VSRs can be encoded in viral genomes and satellite molecules and play an important role in the virus's life cycle and in overcoming host defenses.

Viral and Host Factors Involved in Host Gain and Host Loss by Tomato Leaf Curl Begomoviruses in Tomato and Cucumbers. [PDF]

Mol Plant Pathol
Begomoviruses have jumped hosts between tomatoes and cucumbers, and we found that a short region (transcriptional activator and replication enhancer proteins, TrAp and REn) of tomato leaf curl New Delhi virus is mainly responsible for host jump. ABSTRACT Begomoviruses transmitted by whiteflies cause severe crop losses worldwide.
