Advances in Apple Transformation Technology to Confer Resistance to Fungal Diseases in Apple Crops: A Chilean Perspective Chilean J. Agric. Res.
Polanco,Víctor; Paredes,Mario; Becerra,Viviana; Pérez,Eduardo.
Apple (Malus domestica Borkh.) is one of the most consumed fruit in the world. Genetic transformation is a key process to sustain this demand by permitting the potential enhancement of existing cultivars as well as the development of new cultivars resistant to pests, diseases, and storage problems that occur in the major production areas. This review summarizes the advances of genetic engineering applied to the development of resistant apple cultivars to fungus disease, with particular attention in the generation of apples resistant to Venturia inaequalis (Cooke) G.Winter, the main phytosanitary problem that affects apple crops in Chile.

Genetic diversity of Chondrostereum purpureum (Pers.) Pouzar causing silverleaf disease on blueberries in Chile Gayana Botánica
Rojo,Carmen; Becerra,Viviana; France,Andrés; Paredes,Mario; Buddie,Alan; Balzarini,Monica.
ABSTRACT Blueberry (Vaccinium corymbosum L.) in Chile is being affected by silver disease whose causative agent is Chondrostereum purpureum (Pers.) Pouzar. This fungus causes a decrease in the yield of the fruit and the death of the plant. So far, this disease has not been reported in the literature attacking blueberry plants in Chile. The main objective of this research was to characterize genetically the populations of Ch. purpureum at molecular level using the ITS-RFLP markers. The results of the ITS-RFLP indicate a low level of diversity in the Chilean populations of Ch. purpureum. When analyzing the isolates collected in blueberry, two large groups were configured in the dendrogram. The first one grouped 49 isolates with the same molecular profile and...
