- Spinach (Spinacia oleracea) leaves with vein yellowing were observed in Rajasthan province of India. The plants were severely stunted in growth and exhibited symptoms typical of begomovirus infection. Analysis of collected samples indicated that the infected plants contained a novel begomovirus (showing <91% nucleotide sequence similarity with the known viruses) and its associated betasatellite. Comprehensive analysis on the complexity and recombination suggested that it was probably derived from Papaya leaf curl virus and may have evolved to infect Spinach in absence of the main host. The nucleotide diversity (π) and nucleotide substitution rates for the DNA-A of SYVSV are 0.10382 and 2.436 × 10–3 substitutions site-1 year-1, respectively. Thus mutation and recombination seem to be the driving forces for the emergence and evolution of new begomoviruses. This suggests the existence of a complex recombination pattern to form a “gene pool” of the crop-infecting virus–betasatellite complexes and strengthens the hypothesis for increase of host range of begomovirus, thus raising concern about its spread to other crops.
