https://www.selleckchem.com/products/gw0742.html Gaeumannomyces graminis var. graminis (Ggg) has been the etiological agent of take-all root rot (TARR) in St. Augustinegrass (Stenotaphrum secundatum) and root decline of the other warm-season turfgrasses. Seventy-five Ggg isolates were obtained from St. Augustinegrass in central and east Texas. Evaluation of colony morphologies on potato dextrose agar (PDA) within 2 wk and follow-up multilocus phylogenic analyses revealed three phenotypic groups associated with different Gaeumannomyces species (i) G. floridanus, highly melanized with round colony formation; (ii) G. arxii, none to slightly melanized with round colony formation; and (iii) G. graminicola, highly melanized with irregular colony formation. Further examination with representative isolates from each group revealed that their phenotypic characterizations supported the distinctive genetic groups within Ggg associated with St. Augustinegrass TARR. Gaeumannomyces floridanus isolates grew faster at warmer temperature (30 C) than G. arxii or G. graminicola. Pathogenicity assays using rice seedlings indicated that G. floridanus was more aggressive in disease symptom development than G. arxii or G. graminicola. A multilocus phylogeny reconstruction supported that most of Gaeumannomyces isolates tested in this study were separated into three phylogenetically distinct groups G. floridanus, G. arxii, and G. graminicola. The resolution of intravarietal complexities of causal fungi of TARR is important for proper diagnostics and management strategies for TARR in St. Augustinegrass and other root-decline diseases in warm-season turfgrasses. We aimed to clarify the clinical implication of ultrasound (US)-detected foot joint inflammation in tightly controlled patients with rheumatoid arthritis (RA). We evaluated bilateral foot joints (second to fifth metatarsophalangeal joints of forefoot; tarsometatarsal, cuneonavicular and midtarsal joints of midfoot) of 430 RA patients
