Genetic entanglement between Cercospora species associating soybean purple seed stain por Guillin, Eduardo Alejandro, Olivera, Luiz Orlando, Grijalba, Pablo Enrique, Gottlieb, Alexandra Marina

“…Comparison with sequences from 70 Cercospora species indicated that at least five monophyletic groups of S-PSS-causing agents are currently present in South America. The provided evidence supports the hypothesis that interspecific genetic exchange plays a significant role in the evolutionary dynamics of Cercospora species in this region. …”

The Biology and Ecology of Drosophila suzukii (Diptera: Drosophilidae) por Kirschbaum, Daniel Santiago, Funes, Claudia Fernanda, Buonocore Biancheri, María Josefina, Suárez, Lorena del Carmen, Ovruski Alderete, Sergio Marcelo

“…Preference of egg laying in ripe (or in ripening process), healthy, soft, small fruits (berries and stone fruits) still attached to the plant makes Drosophila suzukii (spotted wing Drosophila, SWD) a severe, harmful pest, capable of producing huge food and economic losses to Asia, Europe, and America. The high degree of polyphagy shown by SWD either in their native region, Eastern and Southeastern Asia, or in the invaded continents, besides its seasonal phenotypic plasticity that allows it adaptations to adverse thermal periods, greatly favors SWD establishment and dispersion into new environments. …”

Genetic engineering of Plum pox virus resistance: 'HoneySweet' plum-from concept to product por Scorza, Ralph, Callahan, Ann, Dardick, Chris, Ravelonandro, Michel, Polak, Jaroslav, Malinowski, Tadeusz, Zagrai, Ioan, Cambra, Mariano, Kamenova, Ivanka

“…Sharka disease, caused by Plum pox virus (PPV) was first recorded in Bulgaria during the early twentieth century and since that first report, the disease has progressively spread throughout Europe and more recently to Asia, Africa, North and South America. Few PPV resistance genes have been found to naturally occur in Prunus and this has led to the investigation of biotech approaches to the development of resistance through genetic engineering (GE). …”
