Última Analysis of 16S rRNA and mxaF genes reveling insights into Methylobacterium niche-specific plant association Genet. Mol. Biol. Dourado,Manuella Nóbrega; Andreote,Fernando Dini; Dini-Andreote,Francisco; Conti,Raphael; Araújo,Janete Magali; Araújo,Welington Luiz. The genus Methylobacterium comprises pink-pigmented facultative methylotrophic (PPFM) bacteria, known to be an important plant-associated bacterial group. Species of this group, described as plant-nodulating, have the dual capacity of producing cytokinin and enzymes, such as pectinase and cellulase, involved in systemic resistance induction and nitrogen fixation under specific plant environmental conditions. The aim hereby was to evaluate the phylogenetic distribution of Methylobacterium spp. isolates from different host plants. Thus, a comparative analysis between sequences from structural (16S rRNA) and functional mxaF (which codifies for a subunit of the enzyme methanol dehydrogenase) ubiquitous genes, was undertaken. Notably, some Methylobacterium spp.... Tipo: Info:eu-repo/semantics/article Palavras-chave: Phylogenetic diversity; Methylotrofics; PPFM; Plant-bacteria interaction. Ano: 2012 URL: http://www.scielo.br/scielo.php?script=sci_arttext&pid=S1415-47572012000100020 Genetic variability of Brazilian isolates of Alternaria alternata detected by AFLP and RAPD techniques BJM Dini-Andreote,Francisco; Pietrobon,Vivian Cristina; Andreote,Fernando Dini; Romão,Aline Silva; Spósito,Marcel Bellato; Araújo,Welington Luiz. The Alternaria brown spot (ABS) is a disease caused in tangerine plants and its hybrids by the fungus Alternaria alternata f. sp. citri which has been found in Brazil since 2001. Due to the recent occurrence in Brazilian orchards, the epidemiology and genetic variability of this pathogen is still an issue to be addressed. Here it is presented a survey about the genetic variability of this fungus by the characterization of twenty four pathogenic isolates of A. alternata f. sp. citri from citrus plants and four endophytic isolates from mango (one Alternaria tenuissima and three Alternaria arborescens). The application of two molecular markers Random Amplified Polymorphic DNA (RAPD) and Amplified Fragment Length Polymorphism (AFLP) had revealed the isolates...
