1. Resistance of cocoa to Moniliophthora perniciosa – progenitors and progenies selection
ABSTRACT Witches' broom, caused by Moniliophthora perniciosa, is the most important cacao disease in Brazil, and the final objective of this study is increasing the level and durability of resistance to this fungus, through the association of different alleles or genes favorable to the character, for the generation of new cocoa varieties. It was conducted, f

2. Seleção precoce para resistência à vassoura-de-bruxa do cacaueiro em novas combinações parentais
RESUMO Progênies de 69 cruzamentos entre genitores obtidos por seleção recorrente para resistência e produtividade foram inoculadas com basidiósporos de Moniliophthora perniciosa. Os sintomas foram avaliados e comparados com aqueles nas progênies de Catongo, SIC 23 e SCA 6, igualmente inoculadas. Quarenta e três das novas progênies não diferiram est

3. Mineral Nutrients and Plant-Fungal Interaction in Cocoa Trees (Theobroma cacao L.)
An infection of the fungus Moniliophthora perniciosa in cocoa trees reduces productivity of the plant. In this study, the concentrations of mineral nutrients in healthy leaves and in leaves of vegetative broom of the cocoa plant were determined, and the relationship between the disease and the nutritional composition of the leaves was assessed. The samples w

4. Resistance to witches’ broom in adult plants and progeny of local varieties of cacao in Southern Bahia
ABSTRACT Plants of local cacao variety from Southern Bahia were evaluated in order to verify if there are different levels of resistance to witches’ broom disease in the study population and if the evaluation of adult plants in the field is a good predictor of these resistance levels. The seedlings were maintained under greenhouse conditions and inoculated

5. Association of genes from different sources of resistance to major cacao diseases
ABSTRACT This study aimed to select genotypes resistant to witches’ broom (WB) and black pod (BP), major cacao diseases in Brazil, as well as incorporate resistance genes to moniliasis supplemented by clones EET75 and UF273, forming populations of second-cycle recurrent selection. Moniliophthora perniciosa (2 × 105 basidiospores/mL) was inoculated on 30-d

7. Cacao families and parents selected as resistant to natural infection of Moniliophthora perniciosa
Abstract The known sources of resistance to witches' broom (WB), a severe disease of cacao, are limited. Aiming to identify families and parents resistant to Moniliophthora perniciosa, a population of 22 families was evaluated by assessing the number of brooms formed per tree during 10 years under field conditions. The population was established in randomize

8. Pathogenic variability of Moniliophthora perniciosa in three agroecological zones of the cacao region of Bahia, Brazil
Abstract Resistant cacao genotypes are the best measure to control the Witches' broom disease of cacao. To ensure efficiency, the pathogen variability in the cacao region of Bahia must be investigated. The pathogenic variability of Moniliophthora perniciosa inocula from nine municipalities was analyzed: Ilhéus, Floresta Azul and Jussari (agroecological zone

9. Atividade antifúngica in vitro do óleo essencial de Ocimum selloi e metilchavicol contra fungos fitopatogênicos
A eficácia do óleo essencial de Ocimum selloi na inibição do crescimento micelial e na germinação de esporos foi avaliada in vitro para os fungos Moniliophthora perniciosa, Colletotrichum gloesporioides e Alternaria alternata. Seis constituintes (99,89%) do total do óleo foram identificados por CG-EM metil chavicol, metil eugenol, β-cariofileno, germ

10. Antifungal and proteolytic activities of endophytic fungi isolated from Piper hispidum Sw
Endophytes are being considered for use in biological control, and the enzymes they secrete might facilitate their initial colonization of internal plant tissues and direct interactions with microbial pathogens. Microbial proteases are also biotechnologically important products employed in bioremediation processes, cosmetics, and the pharmaceutical, photogra

11. Analysis of the ergosterol biosynthesis pathway cloning, molecular characterization and phylogeny of lanosterol 14α-demethylase (ERG11) gene of Moniliophthora perniciosa
The phytopathogenic fungus Moniliophthora perniciosa (Stahel) Aime & Philips-Mora, causal agent of witches' broom disease of cocoa, causes countless damage to cocoa production in Brazil. Molecular studies have attempted to identify genes that play important roles in fungal survival and virulence. In this study, sequences deposited in the M. perniciosa Genome

12. Diversidade genética molecular, produção e resistência à vassoura-de-bruxa em clones de cacau
32 clones de cacau selecionados como resistentes após a epidemia da vassoura-de-bruxa e com destacada produtividade foram caracterizados quanto à diversidade genética e submetidos a nova seleção. Essas plantas foram avaliadas por oito anos na Fazenda Oceania (FO), em Itagibá, BA, Brazil. Os 13 primers microssatélites geraram em média 11,7 alelos (amp
