ABAIDOO, R. C., GEORGE, T., BOHLOOL, B. B., and SINGLETON, P. W. 1990. Influence of elevation and applied nitrogen on rhizosphere colonization and competition for nodule occupancy by different rhizobial strains on field-grown soybean and common bean. Can. J. Microbiol. 36: 92-96. In the absence of indigenous rhizobial populations, the pattern of competition between inoculum strains for nodule o...
The interactions of legumes with symbiotic nitrogen-fixing bacteria cause the formation of specialized lateral root organs called root nodules. It has been postulated that this root nodule symbiosis system has recruited factors that act in early signaling pathways (common SYM genes) partly from the ancestral mycorrhizal symbiosis. However, the origins of factors needed for root nodule organogen...
Dupuytren's disease causes disability because of the development of finger flexion deformities, with distinct nodule and cord formation. This results in physical shortening of the diseased fascial tissue through a combination of cell-mediated contraction and matrix remodeling. It is this fixed tissue fabric shortening that prevents finger extension. In this experimental study, the relative cont...
A 44-year-old woman presented with hyperthyroidism and a nodule in her thyroid. 1311-scintigraphy of the gland showed concentration of the tracer within the nodule and suppressed activity in the rest of the gland. Histology of the resected thyroid proved the nodule to be a papillary carcinoma. The presence of carcinoma within an autonomous hyperactive thyroid in a patient with hyperthyroidism h...
Methods In the Dutch-Belgian randomized lung cancer screening trial (NELSON), the baseline CT screen result was based on the lung nodule with largest volume. According to the protocol, nodule volume<50mm3, 50-500mm3 and >500mm3 led to a negative, indeterminate and positive screen result, respectively. The protocol, however, allowed radiologists to manually adjust screen result in case of high s...
The roles of auxin in the regulation of symbiotic legume nodule formation are unclear. We recently showed that enhanced sensitivity to auxin resulting from overexpression of miR160 inhibits determinate nodule formation in soybean. We examined the roles of miR393 and miR164 in soybean (that forms determinate nodules) and Medicago truncatula (that forms indeterminate nodules). Our results togethe...
