Black, S.J.Jack, R.M.Morrison, W. Ivan[Host-parasite interactions which influence the virulence of Trypanosoma (Trypanozoon) brucei brucei organisms]Host-parasite interactions which influence the virulence of Trypanosoma (Trypanozoon) brucei brucei organisms

Viruses causing severe mosaic, epinasty, defoliation, and premature death of Passiflora spp. were isolated from west central Colombia. Western blot analyses indicated the presence of potyviruses. Two Colombian isolates (COL-22 and -GR) were compared to known potyviruses as to host range, symptoma...

We report the first identification of novel viruses, and sequence of an entire viral genome, by a single step of high-throughput parallel sequencing of small RNAs from diseased, as well as symptomless plants. Contigs were assembled from sequenced total siRNA from plants using small sequence assem...

Infectious laryngotracheitis was diagnosed for the first time in Valle del Cauca, Colombia and confirmed by histopathological and virological methods. Descriptions were made of the history of the outbreak, and gross and microscopic lesions produced by the virus

With the aim to find new sources of resistance to rice hoja blanca (white leaf) disease, transmitted by the insect Tagosodes orizicolus, 660 genotypes were evaluated under greenhouse and field conditions. Seven resistant genotypes were identified, and genomic studies were performed to demonstrate...

Virus‐related degeneration constrains production of quality sweet potato seed, especially under open field conditions. Once in the open, virus‐indexed seed is prone to virus infection leading to decline in performance. Insect‐proof net tunnels have been proven to reduce virus infection under rese...

The number and weight of seeds produced per plant were significantly (P = 0.01) reduced, 47.5 and 56.3%, respectively, in Diacol-Calima bean (Phaseolus vulgaris) plants infected with bean southern mosaic virus (BSMV). The number of pods per plant, on the contrary, was often higher in systemically...

The inheritance of the ability of Sogatodes oryzicola to support replication of the rice hoja blanca virus (RHBV) was studied by following the segregation of progeny of crosses between insects of known pedigree and known ability to support virus replication and transmission. Virus transmission to...
