Última Biological stability of a strain of Cowpea severe mosaic virus over 20 years Rev. Ciênc. Agron. Lima,José Albersio Araujo; Nascimento,Aline Kelly Queiroz do; Silva,Ana Kelly Firmino da; Aragão,Maria do Livramento. Cowpea (Vigna unguiculata) is an important crop of the traditional agriculture system in the Northeast of Brazil. It can be infected by more than 20 virus species and Cowpea severe mosaic virus (CPSMV) is one of the most important pathogens that naturally infect cowpea in Brazil. Several CPSMV isolates were obtained and characterized in the Plant Virus Laboratory at the Federal University of Ceará: CPSMV-CE - the first characterized isolate of the virus obtained from cowpea in the State of Ceará; CPSMV-AL - isolated from cowpea in Alagoas; CPSMV-PE - isolated from cowpea in Pernambuco; CPSMV-PR - obtained from soybean (Glycine max) in Paraná and CPSMV-CROT - isolated from Crotalaria paulinea, in Maranhão. An isolate of CPSMV with the property to infect the... Tipo: Info:eu-repo/semantics/article Palavras-chave: Genetic stability; Cowpea; Biological properties; Biological integrity.

The objective of this work was to identify new sources of simple and multiple resistances to Cowpea severe mosaic virus (CPSMV), Cowpea aphid-borne mosaic virus (CABMV) and Cucumber mosaic virus (CMV) isolates in cowpea (Vigna unguiculata). Thirty-three genotypes from the germplasm bank of Universidade Federal do Ceará were tested as to their resistance to four CPSMV isolates, two CABMV isolates and one CMV isolate. Twenty-five days after the first virus inoculations, all inoculated plants, including the asymptomatic ones, were tested by serology. Genotypes were classified as: immune, plants without symptoms and negative serology; resistant, plants with mild mosaic and positive serology; susceptible, plants with mosaic and positive serology; and highly...
