Pseudomonas syringae pv. actinidiae is an economically significant pathogen responsible for severe bacterial canker of kiwifruit (Actinidia sp.). Bacteriophages infecting this phytopathogen have potential as biocontrol agents as part of an integrated approach to the management of bacterial canker, and for use as molecular tools to study this bacterium. A variety of bacteriophages were previousl...

Bacterial canker, caused by Pseudomonas syringae pv. actinidiae, is one of the most severe diseases of kiwifruit. It has become an international pandemic and threatens the sustainable development of kiwifruit production in all main kiwi-growing regions worldwide. Streptomycin has been the major bactericide for the control of kiwifruit canker, especially in Anhui Province, one of the main kiwifr...

Species of Diaporthe are considered important plant pathogens, saprobes, and endophytes on a wide range of plant hosts. Several species are well-known on citrus, either as agents of pre- or post-harvest infections, such as dieback, melanose and stem-end rot on fruit. In this study we explored the occurrence, diversity and pathogenicity of Diaporthe species associated with Citrus and allied gene...

Throughout many years of studying mycopopulation of weeds, we have found fungi of the Diaporthe/ Phomopsis complex interesting to research. After years of examining plants of Achillea millefolium L., some of them exhibited symptoms of infection typical for Diaporthe/Phomopsis species. A. millefolium was usually found in uncultivated, pasture and forest flora, but also in or nearby sunflower fie...

One genus and species are synonymized in the tribe Empoascini of the subfamily Typhlocybinae. Bhatasca Dworakowska, 1995is a junior synonym of Alebrasca Hayashi & Okada, 1994, Bhatasca rectangulata Qin & Zhang, 2011is a junior synonym of Alebrasca actinidiae Hayashi & Okada, 1994. Furthermore, Bhatasca expansa is (necessarily) transferred to the genus Alebrasca.

BACKGROUND Species identification is essential for controlling disease, understanding epidemiology, and to guide the implementation of phytosanitary measures against fungi from the genus Diaporthe. Accurate Diaporthe species separation requires using multi-loci phylogenies. However, defining the optimal set of loci that can be used for species identification is still an open problem. METHODS ...

Diaporthe aspalathi (Syn. Diaporthe phaseolorum var. meridionalis) is the causal agent of the southern stem canker (SSC) disease in soybean. This disease can kill plants from the middle to the end of the growing season resulting in severe yield loss. The mechanisms of SSC disease development and pathogen invasion of soybean are not fully understood. The genome sequence of D. aspalathi has not b...

Greenhouse and laboratory studies were conducted to determine the identity and pathogenicity of Diaporthe– Phomopsis species complex recovered from eight weed species. The identifications of the eight isolates representing four taxa, including two apparently undescribed species of Phomopsis, were based on colony features in pure culture, morphology of alpha or beta-conidia, and internal transcr...
