Two Castanea plant species, C. henryi and mollissima, are cultivated in China to produce chestnut crops. Leaf spot diseases commonly occur plantations, however, little is known about the fungal species associated with leaf spots. In this study, samples of mollissima were collected from Beijing, Guizhou, Hunan, Sichuan Yunnan Provinces, leaf-inhabiting fungi identified based on morphology phylog...

Keyword spotting deals with the search of a reduced set of keywords in audio content. Phone Lattice-based approaches are very fast but achieve poor results. HMM-based keyword spotting systems deal with filler models to absorb the Out-of-vocabulary (OOV) words and achieve best results although they are slower. We propose a technique which combines them in order to perform a confidence measure to...

background: arbuscular mycorrhizal fungi (amf) have the potential to optimize the rhizospheric soil characteristics considerably thereby affecting plant growth. objectives: the aim is to investigate the effects of fungi inoculation (glomus intraradices) on morphological, physiological and phytochemical traits of rosemary (rosemarinus officinalis l.) under salt stress. methods: a factorial exper...

Searching documents for information and retrieval of relevant documents is a basic activity. Various tools are readily available for searching and retrieval from digital documents, but not much robust methods are available for retrieval from historic documents and old manuscripts as they are not digitized but available in scanned formats. Conventional way of retrieval from scanned document imag...

In contrast to most insect guilds, gall-forming insects are thought to reach highest diversity on sclerophyllous vegetation, such as Neotropical savannas and Mediterranean vegetation types. The water and nutrient stress endured by meristems of canopy trees in tall wet tropical rainforests may cause leaf sclerophylly. Hence, the upper canopies of such ecosystems may represent a suitable habitat ...

Mycosphaerella, one of the largest genera of ascomycetes, encompasses several thousand species and has anamorphs residing in more than 30 form genera. Although previous phylogenetic studies based on the ITS rDNA locus supported the monophyly of the genus, DNA sequence data derived from the LSU gene distinguish several clades and families in what has hitherto been considered to represent the Myc...

Tithonia diversifolia, a member of Compositae native to Central America that produces showy sunflower-like flowers, became an invasive weed in other continents after it was introduced as an ornamental. Little is known about fungal pathogens infecting this plant. Knowledge of its mycobiota is of interest for future biocontrol programmes for T. diversifolia. In Brazil, a cercosporoid hyphomycete ...
