13. Photosynthetic gas exchange and antioxidative system in common bean plants infected by Colletotrichum lindemuthianum and supplied with silicon
This study investigated the effects of silicon (Si) on the resistance of common bean plants to anthracnose caused by Colletotrichum lindemuthianum. The plants were grown in a nutrient solution containing 0 (control) or 2 mM Si (+Si) and both photosynthesis and antioxidative metabolism levels were evaluated. The Si concentrations in the leaf tissues of +Si pl

14. BRS Esteio: common bean cultivar with black grain, high yield potential and moderate resistance to anthracnose
BRS Esteio is a common bean cultivar with black grains of excellent cooking quality, suited for cultivation in 21 Brazilian States. In 77 trials of Value for Cultivation and Use, the cultivar had a normal cycle (90 days), an average yield of 2,529 kg ha-1, which is 8.1% higher than that of the control cultivars, a high yield potential (4,702 kg ha-1), uprigh

15. Management of sorghum anthracnose through diversification of genetic resistance in host population
The aims of the present study were to assess the efficiency of hybrid sorghum mixtures for the management of anthracnose and analyze the virulence diversity and structure in the pathogen populations developed in response to these mixtures. Proportions of 25%, 50% and 75% of the susceptible BRS304 hybrid in relation to the resistant IG150 hybrid were evaluate

16. Expressão diferencial de genes induzidos por antracnose em feijoeiro em resposta à indução da resistência por silício / Differential expression of genes activated by anthracnose in response to silicon induced resistance
O feijão é importante fonte carboidratos, vitaminas, minerais e fibras. No Brasil, a produtividade desta leguminosa é baixa e um dos fatores é a ocorrência de doenças como a antracnose causada pelo Colletothrichum lindemuthianum, que gera perdas de até 100% da produção. Plantas possuem diversos mecanismos de defesa contra patógenos e relatos aponta

17. Common bean cultivar BRS Ametista with large Carioca grains and disease resistance
BRS Ametista is a common bean cultivar with Carioca grain and yields similar to cultivar Pérola, but with larger grain size, resistance to anthracnose and Fusarium wilt. It is recommended for 18 states in all regions of Brazil and can be planted on over 95% of the area used for common bean in the country.

20. Detection of isometric, dsRNA-containing viral particles in Colletotrichum gloeosporioides isolated from cashew tree
Fungi are disease-causing agents in plants and affect crops of economic importance. One control method is to induce resistance in the host by using biological control with hypovirulent phytopathogenic fungi. Here, we report the detection of a mycovirus in a strain of Colletotrichum gloeosporioides causing anthracnose of cashew tree. The strain C. gloeosporio

22. Epidemiology of anthracnose in common bean lines "per se" and in mixture.
This study had de objective to investigate the epidemiology of anthracnose in common bean lines 'per se' and in mixture, aiming to verify whether a mixture of lines with different resistance alleles could provide more durable resistance.
