While it is widely accepted that most animals (Metazoa) do not have endogenous cellulases, relying instead on intestinal symbionts for cellulose digestion, the glycosyl hydrolase family 9 (GHF9) cellulases found in the genomes of termites, abalone, and sea squirts could be an exception. Using information from expressed sequence tags, we show that GHF9 genes (subgroup E2) are widespread in Metaz...
The third countrywide survey on imposex and organotin contamination in the rock shell was conducted in 93 locations along the Japan coast between September 1996 and January 1999. The percentage occurrence of imposex was still high in 86 locations whereas no or rare instances of imposex were found in the remaining seven locations. Severe imposex symptoms were observed in the rock shell populatio...
This multifactorial study used a newly developed ventral videography technique to investigate the feeding behavior of 18-mo-old juvenile greenlip abalone (21.1 g, 55.6 mm), and hybrid abalone (23.4 g, 57.6 mm) fed either a formulated commercial diet or live Ulva sp. at 18 C and 22 C. Feeding behavior was scored in terms of the following activities: quiescence, alertness, moving, feeding, distan...
Sustainable phosphorus (P) use to meet the global food demand is a major challenge for agriculture. A number of soil microorganisms may influence plants’ ability utilize different chemical forms in rhizosphere. Inoculating phosphate-solubilizing together with rock phosphates (RP) has intrigued researchers over century. However, microbe-mediated mobilization mechanisms RP remain seldomly compreh...
Cationic lipodepsipeptides from Pseudomonas spp. have been characterized for their structural and antimicrobial properties. In the present study, the structure of a novel lipodepsipeptide, cormycin A, produced in culture by the tomato pathogen Pseudomonas corrugata was elucidated by combined protein chemistry, mass spectrometry and two-dimensional NMR procedures. Its peptide moiety corresponds ...
The coleopteran insect western corn rootworm (WCR, Diabrotica virgifera virgifera) is an economically important pest in North America and Europe. Transgenic corn plants producing Bacillus thuringiensis (Bt) insecticidal proteins have been useful against this devastating pest, but evolution of resistance has reduced their efficacy. Here, we report the discovery of a novel insecticidal protein, P...
