Diversity of Pectobacterium strains by biochemical, physiological, and molecula...
Silva, Adelaide Siqueira; Luz, José Magno Queiroz; Tebaldi, Nilvanira Donizete; Morais, Tâmara Prado dePectobacterium is a complex taxon of strains with diverse characteristics. It comprises several genera, including Erwinia, Brenneria, Pectobacterium, Dickeya, and Pantoea. Pectobacterium and Dickeya cause diseases in a wide range of plants, including potatoes, where they are causative agents of soft rot in tubers and blackleg in field-grown plants. Characterizing Pectobacterium species allows for the analysis o...
Inoculation of maize with Azospirillum brasilense in the seed furrow
Rezende, Wender Santos; Brandão, Afonso Maria; Brito, Césio Humberto de; Morais, Tâmara Prado deDiversos estudos abordando a inoculação de cereais com micro-organismos diazotróficos são encontrados na literatura. Porém, em muitos experimentos os pesquisadores têm negligenciado a viabilidade da aplicação desses micro-organismos no sulco de semeadura, juntamente com as sementes, e o efeito da concentração das bactérias na fitoestimulação. Este trabalho teve como objetivo avaliar o efeito de doses de inocula...
Reaction of brazilian cotton genotypes to white mold depends on pathogen aggres...
Pestana, Jeferson Rodrigo; Morais, Tâmara Prado de; Nogueira, Ana Paula Oliveira; Cezar Juliatti, FernandoThe expansion of cotton crop into irrigated and high lands of Brazilian Cerrado, despite the possibility of increasing fiber yield, led to the occurrence of diseases previously considered secondary, such as white mold [Sclerotinia sclerotiorum (Lib.) de Bary]. Host genetic resistance is of extreme importance in integrated strategies to manage this disease. Resistance of Brazilian cotton genotypes, challenged wi...
Application of tissue culture techniques in potato
Morais, Tâmara Prado de; Asmar, Simone Abreu; Silva, Herick Fernando de Jesus; Luz, José Magno Queiroz; Melo, Berildo dePotato is the world's most important non-cereal food crop, and therefore, it is considered one of the major food sources for humankind. Its conventional propagation is asexual, by using the tuber, which allows the accumulation and dissemination of pathogens to new cultivation areas. This fact not only impairs the yield of this solanaceous plant, but also threatens the maintenance of genotypes for commercial or ...
Physical-chemical properties of pesticides: concepts, applications, and interac...
Pereira, Vanderley José; Rodrigues da Cunha, João Paulo Arantes; Morais, Tâmara Prado de; Oliveira, João Paulo Ribeiro de; Morais, João Batista deWhat are the molecular properties of agricultural chemicals, how do they function and why should they be studied? How do they affect the agroecosystem and how are they linked to application technologies? These questions arise due to the lack of information in the literature about this issue and form the basis of the current review. In general, a better understanding of the physical-chemical characteristics of a...
Caracterização in vitro e in planta de uma proteína quimérica com atividade ant...
Morais, Tâmara Prado deConselho Nacional de Desenvolvimento Científico e Tecnológico; The phytobacterium Ralstonia solanacearum [(SMITH, 1896) YABUUCHI et al. 1996], causative agent of bacterial wilt and Moko disease, is considered one of the world s most destructive plant pathogen. In Brazil this xylem-restricted bacterium reduces yields of agriculturally important crops and calls for effective disease management strategies, so far ...
Adubação nitrogenada e inoculação com azospirillum brasilense em híbridos de milho
Morais, Tâmara Prado deConselho Nacional de Desenvolvimento Científico e Tecnológico; Maize is one of the world s most important cultivated cereals; however, it presents great challenges for correct fertilization management. Its high nitrogen demand has been the major cause of excessive applications of synthetic nitrogen fertilizers in the crop. As a result, both environmental and economical problems have increased. Therefore, altern...
