Produção e sensibilidade de isolados brasileiros de Xanthomonas axonopodis pv. citri à bacteriocinas

Este trabalho teve por objetivo avaliar a produção e a sensibilidade de 48 isolados brasileiros de X. axonopodis pv. citri (Xac) à bacteriocinas. Pelos resultados obtidos, nenhum isolado de Xac foi sensível às bacteriocinas produzidas pelos isolados bacterianos avaliados

Registration of Common Bacterial Blight Resistant Pinto Bean Germplasm Line ABCP-8

Pinto bean (Phaseolus vulgaris L.) germplasm line ABCP-8 (Reg. no. GP-237, PI 635118) was developed by the University of Nebraska Agricultural Research Division in cooperation with USDA-ARS and released in 2004. This line was bred specifically for enhanced resistnace to common bacterial blight [caused by Xanthomonas campestris pv. phaseoli (Smith) Dye]. Pinto and other dry bean market classes (dark red kidney, great northern, navy, etc.) grown in the U.S.A. east of the continental divide are often attacked by common bacterial blight, a seed-transmitted disease that causes up to 40% yield loss in susceptible cultivars as well as reduction of seed quality through discoloration of infected seed. Development of cultivars with genetic resistance combined from different sources is the most cost effective method to control common bacterial blight
