BACKGROUND Members of the bacterial genus Caldicellulosiruptor are the most thermophilic cellulolytic organisms described to date, and have the ability to grow on lignocellulosic biomass without conventional pretreatment. Different species vary in their abilities to degrade cellulose, and the presence of CelA, a bifunctional glycoside hydrolase that contains a Family 48 and a Family 9 catalytic...

The Glanville fritillary butterfly (Melitaea cinxia) in Finland feeds on the plants Plantago lanceolata and Veronica spicata. These two plant species are distributed heterogeneously and both vary spatially and temporally in iridoid glycoside concentrations. We investigated the associations of plant species and iridoid glycoside (aucubin and catalpol) concentrations with weight, development rate...

Abstract Dioscoreaceae or yam is a family of tuber that comprises many members with variability in utilization and their intensity consumption. This has wide used not only as food but also for medical purposes due to bioactive compounds. One the wild ( Dioscorea hispida Dennst), rich carbohydrates an obstacle high cyanide level. Historically, along cassava, staple some places Indonesia. There l...

The Asiatic fruit fly Drosophila suzukii has recently invaded Europe and North and South America, causing severe damage to fruit production systems. Although agronomic host plants of that fly are now well documented, little is known about the suitability of wild and ornamental hosts in its exotic area. In order to study the potential trophic niche of D. suzukii with relation to fruit characteri...

The diversity and structure of the intestinal microbial community has a strong influence on life history. To understand how hosts and microbes interact, model organisms with comparatively simple microbial communities, such as the fruit fly (Drosophila melanogaster), offer key advantages. However, studies of the Drosophila microbiome are limited to a single point in time, because flies are typic...

A new phenolic glycoside , 2-methoxy-5-(E)-propenyl-phenol-beta-vicianoside, was isolated from the root of Paeonia lactiflora. The structure of the new glycoside was elucidated by chemical and spectroscopic methods.

From the leaves and branches of Fernandoa adenophylla, a lignan glycoside (fernandoside) and a phenylpropanoid glycoside (2"-O-beta-apiosylverbascoside) were isolated together with 12 known compounds. The structural elucidations were based on analyses of physical and spectroscopic data.

Vegetable crops hold a key position in agricultural production worldwide, and the Asian regions such as East, Southeast and South are among the top regions for their exports and imports. However, many pests and diseases threaten the profitability of this agricultural sector, and improving the productivity and quality of vegetables can enhance food security, employment and trade opportunities. F...
