| RAPD markers were used to investigate the distribution of genetic variability among a group of Guignardia citricarpa, G. mangiferae, and Phyllosticta spinarum isolates obtained from several hosts in Brazil, Argentina, Mexico, Costa Rica, Thailand, Japan, United States and South Africa. Pathogenic isolates G. citricarpa Kiely (anamorph form P. citricarpa McAlp Van Der Aa) are the etiological agent of the Citrus Black Spot (CBS), a disease that affects several citric plants and causes substantial injuries to the appearance of their fruits, thus preventing their export. Several previous studies have demonstrated the existence of an endophytic species with high morphological similarity to the causal agent of CBS that could remain latent in the same hosts.... |

| ABSTRACT Mangroves are ecosystems located in the transition zone between land and sea that serve as a potential source of biotechnological resources. Brazil's extensive coast contains one of the largest mangrove forests in the world (encompassing an area of 25,000 km2 along all the coast). Endophytic bacteria were isolated from the following three plant species: Rhizophora mangle, Laguncularia racemosa and Avicennia nitida. A large number of these isolates, 115 in total, were evaluated for their ability to fix nitrogen and solubilize phosphorous. Bacteria that tested positive for both of these tests were examined further to determine their level of indole acetic acid production. Two strains with high indole acetic acid production were selected for use as... |
