The lethal gene 'Luteus-Pa' is found in cacao genotypes (Theobroma cacao) of the Parinari (Pa) series, from Peru. Seedlings affected by this gene have yellowing leaves and subsequently die. We mapped this gene based on microsatellite markers and RAPDs, in order to elucidate the inheritance of 'Luteus-Pa' and investigate possible lethal mechanisms. DNA samples of genitors were amplified with 87 ...

Quantitative and qualitative relationships were found between secreted proteins and their activity, and the hyphal morphology of Moniliophthora perniciosa, the causal agent of witches' broom disease in Theobroma cacao. This fungus was grown on fermentable and non-fermentable carbon sources; significant differences in mycelial morphology were observed and correlated with the carbon source. A bio...

El artículo compila y discute información sobre el origen del cacao fino de aroma su hábitat, basándose en los requerimientos cultivo para un óptimo desarrollo la planta. Asimismo, son descritas algunas fiestas que asocian al cacao, a cultura geo economía región, relacionando con idiosincrasia pobladores pobladoras aquellas plantaciones más emblemáticas Venezuela, enmarcándose como asociado pat...

Aim Cacao (Theobroma cacao L.) is expected to be vulnerable climate change. The objectives of this study were (a) assess the future impact change on in Peru and (b) identify areas where change-tolerant genotypes are potentially present. Location Methods Drawing 19,700 1,200 presence points cultivated wild cacao, respectively, we modelled their suitability distributions using multiple ensemble m...

Bacillus amyloliquefaciens strain 629 is an endophyte isolated from Theobroma cacao L. Here, we report the draft genome sequence (3.9 Mb) of B. amyloliquefaciens strain 629 containing 16 contigs (3,903,367 bp), 3,912 coding sequences, and an average 46.5% G+C content.

The aim of the study was to optimize ethylic fermentation process mucilage juice cacao by Saccharomyces cerevisiae yeast. effected inoculating S. on 0.2 g activated yeast/liter for essay E1, and 0.5 yeast/L E2. Results reveal that increasing pH value in acidic zone raised rate inoculated with than g/L juice. amounts soluble extract transformed yield were greater (90.60%) E1 compared those E2 (8...

The gibberellic acid-stimulated Arabidopsis (GASA/GAST) gene family is widely distributed in plants and involved various physiological biological processes. These genes also provide resistance to abiotic biotic stresses, including antimicrobial, antiviral, antifungal. We are interested characterizing the GASA determining its role process Theobroma cacao. Here, we report 17 tcGASA on six chromos...
