Benzothiadiazole (BTH) induces resistance to Pepper golden mosaic virus (PepGMV) in pepper (Capsicum annuum L.).
Pepper is an economically important crop in many countries around the world but it is susceptible to many diseases. In Mexico, diseases caused by bipartite begomoviruses have emerged as important problems in pepper. Several control strategies have been explored wiht little success; most of them are based on the avoidance of virus transmission and the breeding for resistance. Abiotic inducers ca...
متن کاملOccurrence of Squash yellow mild mottle virus and Pepper golden mosaic virus in Potential New Hosts in Costa Rica
Leaf samples of Solanum lycopersicum, Capsicum annuum, Cucurbita moschata, Cucurbita pepo, Sechium edule and Erythrina spp. were collected. All samples were positive for begomoviruses using polymerase chain reaction and degenerate primers. A sequence of ∼1,100 bp was obtained from the genomic component DNA-A of 14 samples. In addition, one sequence of ∼580 bp corresponding to the coat protein (...
متن کاملEarly and late gene expression in pepper huasteco yellow vein virus.
Viral infections usually take place in an orderly manner and can be divided into at least two phases: an early and a late stage. In geminiviruses, plant viruses with a circular, single-stranded DNA genome, expression of viral genes involves complex regulation strategies that suggest the existence of a pattern of temporal gene expression. In this work, the transcription of pepper huasteco yellow...
متن کاملNucleotide sequence of bean golden mosaic virus and a model for gene regulation in geminiviruses.
We have sequenced the genome of bean golden mosaic virus, which comprises two circular single-stranded DNA molecules (2646 and 2587 nucleotides long) of mostly unique sequence. Comparison of the sequences of bean golden mosaic virus and of cassava latent virus, which share serological relationship but are very different in host range and geographical origin, shows that each virus has a unique 2...
متن کاملInfluence of Virus Concentration on Expression of Cucumber Mosaic Virus Resistance in Pepper
Pepper lines L57 and L113 and cv.Pico are inoculated by 1, 5, 10, 25, 75 μg/ml cucumber mosaic virus (CMV) in inoculum. Both lines are resistant to the virus and cv.Pico is used as a susceptible control. The lines respond with the development of chlorotic (L57) and necrotic (L113) spots on the inoculated leaf. The virus is established only in the inoculated leaves and their petioles of the resi...
