A wilt and eventual dieback disease ot the forage legume Stylosanthes guianens which occurs widely in Colombia and Brazil, is described. The causal agent of the wilt disease is identified as Lasiodiplodia theobromae, a virulent, unspeciaIized, facultative, wound pathogen with worldwide distributi...

African oil palm ringspot virus (AOPRV) had been previously described as a fovea-like virus associated with a lethal disease of African oil palm (Elaeis guineensis) in South America. The original report was based on partial sequence and a distant relationship between AOPRV and Apple stem pitting ...

The complete nucleotide sequences of RNAs 1 and 2 of Rice stripe necrosis virus (RSNV) were determined and compared to the corresponding genomes of all sequenced, rod-shaped plant viruses. The genome organisation of RSNV RNA1 and RNA2 is nearly identical to that of Beet necrotic yellow vein virus...

Electron microscopic examination of thin section from rice hoja blanca virus (RHBV)-infected barnyard [Echinocloa colonum (L.) Link] revealed the occurrence of large masses of flexuous, tubular particles, 8-10 nm wide, both in the cytoplasm and nucleus. These inclusions were absent in cells from ...

Bemisia tabaci (Gennadius) is one of the most important pests of cassava in Africa and several countries of Asia due to the damage caused by direct feeding, the excretion of honeydew, and its capacity as a vector of cassava mosaic geminivirus. There is a general consensus that B. tabaci is a comp...

Subgenomic RNAs of both polarities corresponding to rice hoja blanca virus (RHBV) ambisense RNA4 were detected in RHBV-infected rice tissues. Total RNA extracted from RHBV-infected and noninfected rice tissues and RNA4 purified from RHBV ribonucleoprotein particles were used as templates for prim...

Global interest on plant-microbe-insect interactions is rapidly growing, revealing the multiple ways in which microorganisms mediate plant-herbivore interactions. Phytopathogens regularly alter whole repertoires of plant phenotypic traits, and bring about shifts in key chemical or morphological c...
