1. Adaptability and stability of corn inbred lines regarding resistance to gray leaf spot and northern leaf blight
Abstract The objectives of this study were to identify resistant and susceptible corn inbred lines based on their stability and adaptability for resistance to disease symptoms of gray leaf spot and northern leaf blight, suggest resistant inbred lines aimed at producing synthetics, and identify the sowing dates with higher occurrence of diseases to use these

2. Identificação de QTLs associados à resistência a cercosporiose e produção de grãos em milho / Identification of QTL associated with gray leaf spot resistance and grain yield in corn
A cercosporiose é considerada umas das principais doenças da cultura do milho. A incorporação de resistência genética está entre os principais objetivos dos programas de desenvolvimento de híbridos para as regiões em que a doença é prevalente. A identificação de locos de caracteres quantitativos (QTL) por meio de marcadores moleculares possibili

3. Identificação molecular e morfológica, métodos de esporulação, indução e detecção de cercosporina das espécies de cercospora do milho
Em Minas Gerais são encontradas as três espécies de Cercospora do milho: Cercospora zeina, Cercospora zeae-maydis e Cercospora sorghi f.sp. maydis, e esta última é de fácil separação das demais, por apresentar um índice de velocidade de crescimento micelial maior e pode produzir toxina em meio Suco de Tomate Temperado (STT). As outras duas espécies

4. Quantification of damages and reaction of resistance of commercial mayze hybrids to Cercospora zeae-maydis / QuantificaÃÃo de Danos e ReaÃÃo de resistÃncia de Hibridos Comerciais de Milho a Cercospora Zeae-maydis
With the objective of quantifying the damages caused by mayze gray leaf spot, establish the existing relationship between these damages and the severity of the disease, the resistance of commercial maize hybrids to Cercospora zeae-maydis and determining which is the best timing of evaluation of the disease, four experiments were conducted in two sowing seaso

5. Agressividade de isolados de Cercospora zeae-maydis em genótipos de milho / Aggressiveness of Cercospora zeae-maydis isolates in maize genotypes
Maize (Zea maydis L.) is of great social, cultural and economical importance in Brazil and in the world. Maize diseases are the main factors that reduce crop yield. Gray leaf spot, caused by the fungus Cercospora zeae-maydis Tehon &Daniels, is one of the most important diseases in many countries. Given that the disease can be controlled by the use of resista

6. Cercospora zeae-maydis: esporulação, diversidade morfo-genética e reação de linhagens de milho. / Cercospora zeae-maydis: sporulation, morfological-genetic diversity, and reaction in maize lines.
The incidence and severity of cercospora leaf spot, caused by Cercospora zeae-maydis Tehon &Daniels, increased significantly in Brazil in 2000, being considered today one of the major leaf disease of the crop. Despite this, few researches about the pathosystem come being carried in Brazil. The aims of this work were to identify the suitable culture media and

7. Light-Dependent Death of Maize lls1 Cells Is Mediated by Mature Chloroplasts1
We reported previously the isolation of a novel cell death-suppressing gene from maize (Zea mays) encoded by the Lls1 (Lethal leaf spot-1) gene. Although the exact metabolic function of LLS1 remains elusive, here we provide insight into mechanisms that underlie the initiation and propagation of cell death associated with lls1 lesions. Our data indicate that
