O Nordeste-Semi-Arido brasileiro e apontado como uma das regioes problemas da Terra, apresentado, em consequencia do seu fragil ambiente, altos riscos de desertificacao. Neste trabalho procurou-se analisar qualitativamente um caso concreto da dinamica vegetal de um dos seus setores problema, a regiao de Quixaba, entre os Municipios de Ouricuri e Parnamirim - PE, a partir da interpretacao de fotografias aereas multitemporais (em 1955, 1965 e 1983). Os resultados mostraram uma expansao e mudanca agraria notavel na regiao, mas que, se nao conduzida tecnicamente, podera leva-la a um processo acelerado de degradacao de suas terras. A situacao atual ja e alarmante, com quase 15% das suas terras ja improdutivas pela acao antropica e/ou natural. |

Recent outbreaks of Verticillium wilt diseases in various vegetable crops have been reported in Brazil. This fact was our initial stimulus to carry out a nationwide survey aiming to determine their causal agent(s). Thus far, Verticillium dahliae has been reported as the predominant species based solely on morphological traits. As other Verticillium species can be associated with wilt diseases, we characterized a collection of 80 isolates, collected across 10 agricultural Brazilian regions, by combining morphological, biological, and molecular traits. A multilocus approach was employed for identification of Verticillium species with information from three genomic regions (ribosomal internal transcribed spacer region, glyceraldehyde-3-phosphate dehydrogenase, and actin genes). Only 21 out of the 80 isolates were unable to produce microsclerotia in culture. The analyses of all genomic regions indicated V. dahliae as the sole species associated with vascular wilt of distinct hosts, including major solanaceous vegetables and other hosts such as trawberry, okra, and cacao. Pathogenicity tests confirmed the infection by the V. dahliae isolates and the development of typical disease symptoms on their original hosts. This is the first nationwide characterization of Verticillium isolates associated with major vegetable crops in Neotropical areas. This provides valuable information to design sound management strategies for these diseases, mainly for establishing efficient rotation systems and for the development of resistant cultivars.
