Tuber-specific cytosolic (pB33-cphA(Te)) as well as tuber-specifi

Tuber-specific cytosolic (pB33-cphA(Te)) as well as tuber-specific plastidic (pB33-PsbY-cphA(Te)) expression resulted in significant polymer accumulation solely in the tubers. In plants transformed with pB33-cphA(Te), both cyanophycin synthetase and cyanophycin were detected in the cytoplasm leading to an increase up to 2.3% cyanophycin of dry weight and resulting in small BTSA1 manufacturer and deformed tubers. In B33-PsbY-cphA(Te) tubers, cyanophycin synthetase and cyanophycin were exclusively

found in amyloplasts leading to a cyanophycin accumulation up to 7.5% of dry weight. These tubers were normal in size, some clones showed reduced tuber yield and sometimes exhibited brown sunken staining starting at tubers navel. During a storage period over of 32 weeks of one selected clone, the cyanophycin content R788 inhibitor was stable in B33-PsbY-cphA(Te) tubers but the stress symptoms increased. However, all tubers were able to germinate. Nitrogen fertilization in the greenhouse led not to an increased cyanophycin yield, slightly reduced protein content, decreased starch content, and changes in the amounts of bound and free arginine and aspartate, as compared with control tubers

were observed.”
“Two endophytic strains of the entomopathogenic fungus Tolypocladium cylindrosporum, originally isolated from the grass Festuca rubra, were artificially inoculated in tomato and bean plants. Strains 11-1L and 11-0BR were isolated from asymptomatic leaf fragments of both plant species at 3, 7, 14, 21, and

35 days after their inoculation. The percentage of leaf fragments infected Selleck WZB117 by the fungus in inoculated leaves decreased at each sampling time, and no systemic colonization of the plants occurred. The two T. cylindrosporum strains tested were isogenic, differing in the infection by the victorivirus TcV1, harboured by strain 11-1L, but not by 11-0BR. The percentage of infected leaf fragments in leaves inoculated with the virus infected strain was greater in bean than in tomato plants, while the virus-free strain was more successful in tomato than in bean plants. This result suggests that the mycovirus infection can affect the adaptation of T. cylindrosporum to particular host plants.”
“The bacterium Clostridium bornimense M2/40 is a mesophilic, anaerobic bacterium isolated from a two-phase biogas reactor continuously fed with maize silage and 5% wheat straw. Grown on glucose, it produced H-2, CO2, formiate, lactate and propionate as the main fermentation products, of which some compounds serve as substrates for methanogenic Archaea to form methane. Here, the whole genome sequence of the bacterium consisting of two circular replicons is reported. This genome information provides the basis for further studies addressing metabolic features of the isolate and its role in anaerobic biomass degradation. (C) 2014 Elsevier B.V. All rights reserved.
