Abstract:
... Pseudomonas savastanoi pv. phaseolicola causes halo blight disease in the common bean Phaseolus vulgaris. The bacterium invades the leaf apoplast and uses a type III secretion system to inject effector proteins into a bean cell to interfere with the bean immune system. Beans counter with resistance proteins that can detect effectors and coordinate effector-triggered immunity responses transduced b ...

Abstract:
... Ornamental production systems are complicated to manage due to the many species and genera that may be grown and handled together on a single production site. Ornamentals are threatened by various phytopathogenic fungi in greenhouse and field production. Among these, Botrytis cinerea is one of the most notorious pathogens of ornamentals, specifically cut flowers. B. cinerea is responsible for caus ...

Abstract:
... In many cities, high land vacancy has contributed to negative outcomes including visual blight, loss of sense of community and safety, and high crime rates. Although studies show that vacant lot greening programs reduce crime rates in high-vacancy areas, little is known about the impacts of resident-owner-based vacant lot repurposing initiatives on crime. We evaluated the impacts of one such initi ...

Pepper growers rely heavily on pesticides, but toxicity hazards to farm-workers, consumers, non-target organisms as well as environmental contamination cause great concern. Furthermore, the development of pesticide resistance is problematic. The objective ...

Abstract:
... Xanthomonas oryzae pathovar oryzae (Xoo) uses transcription activator-like effectors (TALEs) to cause bacterial blight (BB) in rice. In turn, rice has evolved several mechanisms to resist BB by targeting TALEs. One mechanism involves the nucleotide-binding leucine-rich repeat (NLR) resistance gene Xa1 and TALEs. Reciprocally, Xoo has evolved TALE variants, C-terminally truncated versions (interfer ...

The translocon is hypothetically assembled by bacterial translocators in association with the assumed receptors situated on eukaryotic plasma membranes. This hypot ...

Abstract:
... The type IV pilus (T4P), a special class of bacterial surface filament, plays crucial roles in surface adhesion, motility, biofilm formation, and virulence in pathogenic bacteria. However, the regulatory mechanism of T4P and its relationship to bacterial virulence are still little understood in Xanthomonas oryzae pv. oryzae (Xoo), the causal pathogen of bacterial blight of rice. Our previous studi ...
