Mechanism of the Generation of New Somatic Compatibility Groups within Thanatephorus cucumeris (Rhizoctonia solani)
Single-basidiospore isolates (SBIs) were obtained from field isolates of Thanatephorus cucumeris (Rhizoctonia solani) AG-1 IC and AG-2-2 IV. Formation of distinctive tufts, a recognized feature of heterokaryon synthesis, was observed, and isolates derived from hyphal-tipped tuft hyphae were obtained following pairings between various strains. Three distinctive types of tufts were formed: the fi...
متن کاملHigh levels of gene flow and heterozygote excess characterize Rhizoctonia solani AG-1 IA (Thanatephorus cucumeris) from Texas.
To date, much of the genetics of the basidiomycete Thanatephorus cucumeris (anamorph = Rhizoctonia solani) remains unknown. Here, we present a population genetics study using codominant markers to augment laboratory analyses. Seven single-copy nuclear RFLP markers were used to examine 182 isolates of Rhizoctonia solani AG-1 IA collected from six commercial rice fields in Texas. Thirty-six multi...
متن کاملAnálise da microtração em esmalte de dois sistemas adesivos ativados por LED ou por luz halógena
With the development of composite resin polymerization techniques, LEDs were introduced to the market place. Based on the studied literature, the aim of this study was to evaluate, through microtensile testing, the bond strength to enamel of a composite resin associated to a conventional (multi-bottle) adhesive system or to a self etching primer adhesive system, polymerized by halogen light or ...

A pancreatite causada por fármacos ocorre numa incidência de 1,4-2% dos casos de pancreatite aguda, e deve ser equacionada sempre que as causas habituais de pancreatite aguda forem excluídas. Na maioria dos casos a gravidade da pancreatite por fármacos é pequena. A pancreatite aguda induzida por estatinas tem sido reportada pouco frequentemente mas, face à existência de referências de casos de ...

Interconnection networks are a key component of a variety of systems. Today, low-latency and contention-free interconnection networks are demanded for the execution of many applications in systems like supercomputers, clusters of PCs, and others. There are many issues involved in successful high-performance interconnects. Among them, quality of service (QoS) is responsible of guaranteeing that ...
