1. Amarelos da videira: identificação e análise filogenética dos fitoplasmas, transmissão dos agentes causais e otimização da diagnose / Grapevine yellows: identification and phylogenetic analyses of the phytoplasmas, transmition of the causal agents and diagnosis optimization
Phytoplasmas are wall-less prokaryotes, phloem-limited plant pathogens, belonging to Mollicute class. They are agents of diseases that cause serious damage to a diversity of cultivated especies. Grapevine (Vitis sp) is the third most cultivated fruit crop in the world and it has high economical impact in Brazil. Phytossanitary aspects are important productio

4. Resistance of brazilian sugarcane cultivars to ratoon stunting disease basead on the rate of stalk colonization by Leifsonia xyli subsp. Xyli. / Avaliação da resistência de variedades de cana-de-açúcar ao raquitismo-da-soqueira com base na taxa de colonização dos colmos por Leifsonia xyli subsp. xyli.
The tissue blot immunoassay (TBIA) for detecting Leifsonia xyli subsp. xyli (Lxx) colonized vascular bundles (CVB) were used in determining the reaction of 28 brazilian sugarcane cultivars to ratoon stunting disease (RSD), including CB47-355, CB41-76 e CB49-260 as resistant, intermediate and susceptible standards. For each cultivar, 16 buds were hot water tr
