| transgenic potatoes expressing a novel cationic peptide are resistant to late blight and pink rot. | potato is the world's largest non-cereal crop. potato late blight is a pandemic, foliar wasting potato disease caused by phytophthora infestans, which has become highly virulent, fungicide resistant, and widely disseminated. similarly, fungicide resistant isolates of phytophthora erythroseptica, which causes pink rot, have also become an economic scourge of potato tubers. thus, an alternate, cost effective strategy for disease control has become an international imperative. here we describe a st ... | 2004 | 15198205 |
| variation in antibiosis ability, against potato pathogens, of bacterial communities recovered from the endo- and exoroots of potato crops produced under conventional versus minimum tillage systems. | the culturable component of bacterial communities found in the endoroot and associated exoroot (root zone soil) was examined in potatoes (solanum tuberosum l.) grown under either conventional or minimum tillage systems. bacterial species--abundance relationships were determined and in vitro antibiosis ability investigated to discover whether tillage practice or bacteria source (endo- or exoroot) influenced bacterial community structure and functional versatility. antibiosis abilities against phy ... | 2005 | 16234863 |
| biologically active endophytic streptomycetes from nothofagus spp. and other plants in patagonia. | endophytic streptomycetes have been isolated and characterized from several species of nothofagus and other plants growing in the southern reaches of patagonia. no endophytic streptomycete was obtained from any plant species studied in northern patagonia. however, from southern patagonia, biologically active streptomyces spp. from several plant species were isolated. each isolate, as studied by scanning electron microscopy (sem), has small hyphae, some produce typical barrel-shaped spores in cul ... | 2007 | 16944339 |
| bioactive endophytic streptomycetes from the malay peninsula. | three novel endophytic streptomycetes have been isolated and characterized from plants with ethnobotanical uses on the malay peninsula including: thottea grandiflora (family -aristolochiaceae), polyalthia spp. (family -annonaceae), and mapania sp. (family -cyperaceae). each isolate, as studied by scanning electron microscopy, has small hyphae, and produces typical barrel-shaped spores arising by hyphal fragmentation. interestingly, although none has any detectable antibacterial killing propertie ... | 2007 | 17608698 |
| a methodology to detect and quantify five pathogens causing potato tuber decay using real-time quantitative polymerase chain reaction. | abstract late blight (phytophthora infestans), pink rot (phytophthora erythroseptica), leak (pythium ultimum), dry rot (fusarium sambucinum), and soft rot (erwinia carotovora subsp. carotovora and subsp. atroseptica) are particularly damaging diseases of stored potato tubers worldwide. in this study, we present a methodology to detect and quantify the causal agents of the five aforementioned diseases from whole potato tubers, using real-time quantitative-polymerase chain reaction. six primer pai ... | 2006 | 18944060 |
| phylogenetic relationship of phytophthora cryptogea pethybr. & laff and p. drechsleri tucker. | the phylogeny and taxonomy of phytophthora cryptogea and phytophthora drechsleri has long been a matter of controversy. to re-evaluate this, a worldwide collection of 117 isolates assigned to either p. cryptogea, p. drechsleri or their sister taxon, phytophthora erythroseptica were assessed for morphological, physiological (pathological, cultural, temperature relations, mating) and molecular traits. multiple gene phylogenetic analysis was performed on dna sequences of nuclear (internal transcrib ... | 2010 | 20943142 |
