In a pot experiment, BAU-Biofungicide (Trichoderma harzianum) neem oil and curaterr (carbofuran) 5G were tested against root-knot (Meloidogyne javanica) of two papaya varieties Kashempuri and Deshi papaya. Seedlings were inoculated with second stage larvae of M. javanica. Neem oil (5 ml/ 10g seeds) and BAU-Biofungicide (1:4) were used as seed treatant and curaterr as side dressing. Both the bio...

Dressed in white, hooded ‘‘personal protection suits,’’ Greenpeace activists donned goggles, gloves, and respiratory masks—the kind of dress you expect to see in the clean zone of a nanotechnology laboratory, not in a field in bucolic northeast Thailand. Easily bridging a barbed wire fence with a stepladder, they began pulling transgenic papaya (Carica papaya) from the trees, throwing the fruit...

Plant regeneration and somatic embryogenesis through interspecific hybridization among different Carica species were studied for the development of a papaya ringspot virus-resistant variety. The maximum fruit sets were recorded from the cross of the native variety C. papaya cv. Shahi with the wild species C. cauliflora. The highest hybrid embryos were recorded at 90 days after pollination and t...

Papaya leaf distortion mosaic virus (PLDMV) is becoming a threat to papaya and transgenic papaya resistant to the related pathogen, papaya ringspot virus (PRSV). The generation of infectious viral clones is an essential step for reverse-genetics studies of viral gene function and cross-protection. In this study, a sequence- and ligation-independent cloning system, the In-Fusion(®) Cloning Kit (...

Dengue is an acute febrile viral infection affecting several tropical inhabitants. Carica papaya L. is a plant of choice for symptomatic treatment of dengue in several countries. In India, the plant, particularly the leaf extract is very popular in the management of Post Graduate dengue. Presently, several studies have been carried out on this plant to investigate its role in the management of ...

1 ➥ page 4 A close relative of the human rickettsial pathogens causing such diseases as typhus and spotted fever has been found associated with papaya bunchy top disease, which greatly limits papaya production in the Caribbean area. It is the first rickettsia found to parasitize plants, and the discovery has important implication not only to respect to disease diagnosis and management, but also...

th (Hafmer, 1998) and was introduced in India in 16 century from Malacca (Kumar and Abraham, 1983). Papaya is one of the most important fruit crops of Hawaii, Malaysia, Burma, Sri Lanka, India, Queens Land, South Africa, and other tropical and sub-tropical countries of the world. Papaya occupies 2.0 per cent total fruit crop area and 5.3 per cent of total fruit production in India (5381.73 thou...

Papaya (Carica papaya) is a crop of great economic importance, and the species was among the first plants to have its genome sequenced. However, there has never been a complete species-level phylogeny for the Caricaceae, and the crop's closest relatives are therefore unknown. We investigated the evolution of the Caricaceae based on sequences from all species and genera, the monospecific Carica,...

UNLABELLED Dengue virus belongs to the virus family Flaviviridae. Dengue hemorrhagic disease caused by dengue virus is a public health problem worldwide. The viral non structural 2B and 3 (NS2B-NS3) protease complex is crucial for virus replication and hence, it is considered to be a good anti-viral target. Leaf extracts from Carica papaya is generally prescribed for patients with dengue fever,...

Papaya meleira virus (PMeV), a double-stranded RNA (dsRNA) virus present in the latex of papaya (Carica papaya L.), is the causal agent of ‘meleira’ or ‘sticky disease’, which prevails in eastern Brazil. Disease management strategies in the orchards are impaired by the lack of knowledge on PMeV transmission. We have therefore evaluated inoculation methods (five mechanical and one biological) fo...
