genetic and metabolic biodiversity of trichoderma from colombia and adjacent neotropic regions. | the genus trichoderma has been studied for production of enzymes and other metabolites, as well as for exploitation as effective biological control agents. the biodiversity of trichoderma has seen relatively limited study over much of the neotropical region. in the current study we assess the biodiversity of 183 isolates from mexico, guatemala, panama, ecuador, peru, brazil and colombia, using morphological, metabolic and genetic approaches. a comparatively high diversity of species was found, c ... | 2009 | 19439189 |
strain-specific colonization pattern of rhizoctonia antagonists in the root system of sugar beet. | to develop effective biocontrol strategies, basic knowledge of plant growth promotion (pgp) and root colonization by antagonists is essential. the survival and colonization patterns of five different biocontrol agents against rhizoctonia solani ag2-2iiib in the rhizosphere of greenhouse-grown sugar beet plants were analysed in single and combined treatments. the study included bacteria (pseudomonas fluorescens l13-6-12, pseudomonas trivialis re(*) 1-1-14, serratia plymuthica 3re4-18) as well as ... | 2010 | 20618857 |
characterization of field isolates of trichoderma antagonistic against rhizoctonia solani. | the aim of the present study was to characterize sixteen isolates of trichoderma originating from a field of sugar beet where disease patches caused by rhizoctonia solani were observed. use of both molecular and morphological characteristics gave consistent identification of the isolates. production of water-soluble and volatile inhibitors, mycoparasitism and induced systemic resistance in plant host were investigated using in vitro and in vivo tests in both sterilized and natural soils. this fu ... | 2010 | 20943179 |
Stabilization of the a2 Isoform of Na,K-ATPase by Mutations in a Phospholipid Binding Pocket. | The a2 isoform of Na,K-ATPase plays a crucial role in Ca(2+) handling, muscle contraction, and inotropic effects of cardiac glycosides. Thus, structural, functional, and pharmacological comparisons of a1, a2, and a3 are of great interest. In Pichia pastoris membranes expressing human a1ß1, a2ß1, and a3ß1 isoforms, or using the purified isoform proteins, a2 is most easily inactivated by heating and detergent (a2 » a3 > a1). We have examined an hypothesis that instability of a2 is caused by weak i ... | 2011 | 22027833 |
