Microorganisms are increasingly being recognized as the causative agents in the diseases of marine higher organisms, such as corals, sponges, and macroalgae. Delisea pulchra is a common, temperate red macroalga, which suffers from a bleaching disease. Two bacterial strains, Nautella italica R11 and Phaeobacter gallaeciensis LSS9, have been shown in vitro to cause bleaching symptoms, but previou...

Lithospermum erythrorhizon cell cultures have been used to produce plant secondary metabolites, as well as in biosynthetic studies. Shikonin, a representative secondary metabolite of L. erythrorhizon, was first produced industrially by dedifferentiated cell cultures in the 1980s. This culture system has since been used in research on various plant secondary metabolites. Other boraginaceaeous pl...

A phytochemical investigation of the least polar organic extracts of Arnebia hispidissima (Lehm.) DC. roots has led to the isolation of two unique polycyclic geranylhydroquinone-derived metabolites, arnebacene (1) and arnebidin (2), along with some known phenolic metabolites viz., arnebin-7 (3) and vanillic acid (4). The chemical identification of the new isolated compounds, including their rel...

The first zoeal stages of Geograpsus lividus (H. Milne Edwards, 1837) and Goniopsis pulchra (Lockington, 1876), both obtained from laboratory hatched material in Panama, are described and illustrated. Geograpsus was one of the few genera of Grapsinae for which larval data were unavailable. Zoeal features are compared with those of other genera included in Grapsinae, and several shared morpholog...

New data on Chinese Tersilochinae are provided: one species, Tersilochus scutatus sp. n., is described from Liaoning province of China and the Russian Far East, and two species, Barycnemis bellator (Müller) and Tersilochus curvator Horstmann, are new records from China. Thus, this work raises the total number of known Chinese species to 31. Two close species, Diaparsis pulchra Khalaim and D. ra...

PREMISE OF THE STUDY Chloroplast and mitochondrial microsatellites were identified to study the population genetics of Millettia pinnata (Fabaceae). METHODS AND RESULTS Based on publicly available plastid genome sequence data of M. pinnata, 42 primer pairs were developed, of which 17 displayed polymorphisms across 89 individuals from four populations. For chloroplast loci, two to six alleles ...

We introduce PULCHRA, a fast and robust method for the reconstruction of full-atom protein models starting from a reduced protein representation. The algorithm is particularly suitable as an intermediate step between coarse-grained model-based structure prediction and applications requiring an all-atom structure, such as molecular dynamics, protein-ligand docking, structure-based function predi...

BACKGROUND Tidal (12.4 hr) cycles of behavior and physiology adapt intertidal organisms to temporally complex coastal environments, yet their underlying mechanism is unknown. However, the very existence of an independent "circatidal" clock has been disputed, and it has been argued that tidal rhythms arise as a submultiple of a circadian clock, operating in dual oscillators whose outputs are hel...

Four Valiatrella species, Valiatrella pulchra (Gorochov, 1985), Valiatrella sororia (Gorochov, 2002), Valiatrella laminaria Liu & Shi, 2007 and Valiatrella multiprotubera Liu & Shi, 2007, recorded from China are reviewed. A new species, Valiatrella persicifolius sp. nov., is described and illustrated.
