Black pod rot, caused by Stramenopiles of the genus Phytophthora, leads to serious production losses in all cocoa growing zones. In order to reduce the impact of these pests, preference is given to genetic control using resistant varieties, and sources of resistance are actively being sought, particularly in wild cacao trees. Surveys were undertaken in the natural cacao tree populations of sout...

The highly conserved TIFY domain is included in the TIFY protein family of transcription factors, which is important in plant development. Here, 28 TIFY family genes were identified in the Gossypium raimondii genome and classified into JAZ (15 genes), ZML (8), PPD (3), and TIFY (2). The normal (TIF[F/Y]XG) motif was dominant in the TIFY family, excluding the ZML subfamily, in which TLSFXG was p...

The hemibiotrophic basidiomycete fungus Moniliophthora perniciosa, the causal agent of Witches' broom disease (WBD) in cacao, is able to grow on methanol as the sole carbon source. In plants, one of the main sources of methanol is the pectin present in the structure of cell walls. Pectin is composed of highly methylesterified chains of galacturonic acid. The hydrolysis between the methyl radica...

Pb is a metal which is highly toxic to plants and animals, including humans. High concentrations of Pb have been observed in beans of T. cacao, as well as in its products. In this work, we evaluated the molecular, biochemical, and ultrastructural alterations in mature leaves and primary roots of seedlings of two progenies of T. cacao, obtained from seed germination in different concentrations o...

Moniliophthora roreri , the cause of moniliasis or frosty pod rot, occurs on the neotropical rainforest genera Theobroma and Herrania . While this basidiomycete has had devastating effects on the cacao tree ( T. cacao ) in tropical America, where it is confined, little is known of its biogeography and intraspecific genetic variability. Here, AFLP and ISSR profiles of 94 isolates of M. roreri fr...

El trabajo se realizó en cantón Carmen, provincia de Manabí, Ecuador; con el objetivo analizar manejo agronómico del cultivo Cacao Nacional (Theobroma cacao L.) la Corporación Agropecuaria Pequeños Agricultores Manga Cura; aplicó una encuesta carácter cualitativo categórico para determinar labores preculturales y culturales cultivo, a muestra 60 productores población 340; los datos obtenidos an...

Para estudiar la toxicidad del cadmio (Cd) presente en productos de chocolate es necesario conocer su concentración total y determinar cantidad Cd que bioaccesible el cuerpo humano. Este trabajo se enfocó evaluar bioaccesibilidad formulaciones chocolatería con concentraciones componentes diferentes por digestión gastrointestinales in vitro. Esta realizó a través un titulador automático control ...

Introducción. La polinización es importante en gran parte de los sistemas productivos mundiales, tal el caso del cultivo cacao (Theobroma L.), cual depende la actividad insectos para su polinización. Objetivo. Recopilar las investigaciones más relevantes que incluyen factores determinantes cacao. Desarrollo. El presente trabajo fue realizado entre 2021 y 2022, con una búsqueda exhaustiva biblio...
