N1-(2-chloro-4-pyridyl)-N3-phenylurea (CPPU), a synthetic cytokinin-active compound, is widely applied to induce parthenocarpic fruit set and enhance melon fruit enlargement (Cucumis melo L.). CPPU may also influence fruit quality; however, the mechanisms through which this occurs remain unknown. We investigated the differences in volatile emission...

Muskmelon (Cucumis melo L.) is an important economic crop in China, which is planted on more than 376, 000 hectares with over 13 million tons of annual fruit production. In February 2020, a serious bacterial stem and leaf rot disease on muskmelon plants was observed in greenhouses in Liguo Town, Ledong County, Hainan Province, China (18.54° N, 108....

Objectives The gray mold fungus Botrytis cinerea (B. cinerea) infects a wide range of crops before and after harvest, causing huge losses worldwide. Inhibition mechanisms of B. cinerea in vitro and in plants by calcium propionate (CP), generally recognized as a safe substance, are described in this study. Materials and methods Wild-type and transg...
Article
Full-text available
Botrytis cinerea is a pathogenic fungus that causes gray mold disease in a broad range of crops. The high intraspecific variability of B. cinerea makes control of this fungus very difficult. Here, we isolated a variant B05.10M strain from wild-type B05.10. The B05.10M strain showed serious defects in mycelial growth, spore and sclerotia production,...

Fusarium asiaticum belongs to one of the phylogenetical subgroups of the F. graminearum species complex and is epidemically predominant in the East Asia area. The life cycle of F. asiaticum is significantly regulated by light. In this study, the fungal blue light receptor white collar complex (WCC), including FaWC1 and FaWC2, were characterized in...

Article
Full-text available
Short-wave ultraviolet (UV-C) treatment represents a potent, clean and safe substitute to chemical sanitizers for fresh fruit preservation. However, the dosage requirement for microbial disinfection may have negative effects on fruit quality. In this study, UV-C was found to be more efficient in killing spores of Botrytis cinerea in dark and red li...

In recent years, melon culture in East China represented by Shanghai district has been severely affected by a stem rot disease. Symptoms were described as the presence of badly water-soaked soft rot associated with spilled brown juice in the later stages. Based on our disease diagnosis study, 30 bacteria were isolated from the stem tissues of affec...
Article
Full-text available
Imported kiwifruit affected by soft rot on Shanghai fruit market was selected for pathogen isolation and identification. The pathogenicity of different strains was compared. Morphological detection was combined with molecular tools to identify the main pathogenic strains as well as their biological characteristics. The results showed that Phomopsis...

Botrytis cinerea is a necrotrophic pathogen that causes gray mold disease in a broad range of plants. Dihydroxynaphthalene (DHN)-melanin is a major component of the extracellular matrix of B. cinerea, but knowledge of the exact role of melanin biosynthesis in this pathogen is unclear. In this study, we characterize two genes in B. cinerea, bcpks13...

Extrusomes of different categories in ciliates have been suggested to have different structures and functions. To investigate the characteristics of extrusomes in the hypotrichous ciliate, we examined Architricha indica using scanning and transmission electron microscopy and electron microscopic enzymo-cytochemistry. The results showed that the mat...
Article
Phytochrome-like histidine kinases are photoreceptors that help a wide variety of bacteria and fungi perceive environmental light. In this study, a putative histidine kinase gene Bcphy3 from Botrytis cinerea was disrupted, and a Bcphy3 mutant ΔBcphy3-P21 was obtained. This mutant formed smaller colonies on PDA media compared to the wild-type strain...

Asparagus spears are usually vulnerable to pathogenic micro‐organisms. In this study, 217 pathogens were isolated from symptomatic asparagus, and one highly virulent fungus (designated EXAP‐08) isolated from the rotted asparagus spears in cold storage was characterized in detail. Koch's postulates were checked through pathogenicity tests, indicatin...

Rhizobia establish a symbiotic relationship with their host legumes to induce the formation of nitrogen-fixing nodules. This process is regulated by many rhizobium regulators, including some two-component regulatory systems (TCSs). NtrY/NtrX, a TCS that was first identified in Azorhizobium caulinodans, is required for free-living nitrogen metabolis...

In this paper, we define reusable inference steps for content-based recommender systems based on semantically-enriched collections. We show an instantiation in the case of recommending artworks and concepts based on a museum domain ontology and a user profile consisting of rated artworks and rated concepts. The recommendation task is split into fo...

A new bacterial secondary messenger, bis-(3',5')-cyclic dimeric guanosine monophosphate (c-di-GMP), is usually synthesized or decomposed by proteins containing GGDEF or glutamate-alanine-leucine (EAL) domain. They often act as cyclase or phosphodiesterase of c-di-GMP and their genes are distributed among almost all bacteria according to known genom...

This paper describes a real-time routing system that implements a mobile museum tour guide for providing personalized tours tailored to the user position inside the museum and interests. The core of this tour guide originates from the CHIP (Cultural Heritage Information Personalization) Web-based tools set for personalized access to the Rijksmuseum...

In this paper we outline challenges for user modeling and personalization with spatial information. To illustrate those challenges we use a use case with a real-time routing system that implements a mobile museum guide for providing personalized tours tailored to the user position inside the museum and her interests. In this scenario we combine on...

Metadata vocabularies provide various semantic rela-tions between concepts. For content-based recommender systems, these relations enable a wide range of concepts to be recommended. However, not all semantically re-lated concepts are interesting for end users. In this pa-per, we identified a number of semantic relations, which are both within one v...

This paper presents an approach to exploit widely used tag annotations to address two important issues in user-adaptive systems: the cold-start problem and the integration of distributed user models. The paper provides an example of re-use of user interaction data (tags) generated by one application into another one in similar domains for providing...

In this paper we propose an approach to generate personal-ized guided tours based on a finite collection of tours obtained by tracking the navigation of expert users. Our proposal is based on a variant of decision theory, that uses a regret function to measure the difference between a proposed decision and a finite collection of expert decisions, g...

In this paper we propose a tentative framework (R3) for adapting a sequence of predictions (guided tour) generated by what we call a serial recommender. The R3 framework (rate, recommend, regret) is applied to the construction of personalized guided tours, based on expert advice, in the domain of cultural heritage, in particular digital dossiers ab...
