Diallel analysis of maize resistance to Phaeosphaeria maydis [PDF]
Scientia Agricola, 2004 In breeding programs directed towards genetic resistance against diseases, the estimation of genetic parameters that control resistance allows the introduction of resistance into suscetible germplasm to be clearly focused. The purposes of this study were

Segmentation-based lightweight multi-class classification model for crop disease detection, classification, and severity assessment using DCNN. [PDF]
PLoS ONELeaf diseases in Zea mays crops have a significant impact on both the calibre and volume of maize yield, eventually impacting the market. Prior detection of the intensity of an infection would enable the efficient allocation of treatment resources and ...

Alterações na fotossíntese e na transpiração de folhas de milho infetadas por Phaeosphaeria maydis [PDF]
Fitopatologia Brasileira, 2001 O efeito da mancha foliar de Phaeosphaeria, causada por Phaeosphaeria maydis, na taxa líquida de fotossíntese e na transpiração de folhas de milho (Zea mays) foi avaliado no campo em três híbridos e uma linhagem de milho. A taxa líquida de fotossíntese foi relacionada à severidade da doença por meio do modelo Px/Po=(1-x )beta, onde Px representa a taxa

Quantitative Trait Loci Conditioning Resistance to Phaeosphaeria Leaf Spot of Maize Caused by Phaeosphaeria maydis [PDF]
Plant Disease, 2005 Phaeosphaeria leaf spot (PLS) is a potentially important disease of maize (Zea mays) that has appeared in winter breeding nurseries in southern Florida. Inbred lines related to B73 are particularly susceptible to Phaeosphaeria leaf spot, whereas inbreds related to Mo17 are highly resistant.

Zymoseptoria tritici Effectors Structurally Related to Killer Proteins UmV-KP4 and UmV-KP6 Inhibit Fungal Growth, and Define Extended Protein Families in Fungi. [PDF]
Mol Plant PatholThe fungal effectors Zt‐KP4‐1 and Zt‐KP6‐1 of Zymoseptoria tritici are structural homologues of killer toxins KP4 and KP6α of Ustilago maydis, are antifungal, and their structural homologues are widespread in fungi. ABSTRACT Fungal effectors play crucial roles in plant infection. Despite low sequence identity, they were recently discovered to belong to

Yield Loss Potential of Phaeosphaeria Leaf Spot of Maize Caused by Phaeosphaeria maydis in the United States [PDF]
Plant Disease, 2005 The ability of Phaeosphaeria leaf spot (PLS) to reduce yields of maize was evaluated over two winter growing seasons in southern Florida. Nine commercial maize hybrids, varying in reaction to PLS, were planted in a split-plot design with hybrids as whole plots and inoculated versus uninoculated treatments as subplots.

Diallel crosses among maize lines with emphasis on resistance to foliar diseases
Genetics and Molecular Biology, 2000 Ten elite maize (Zea mays L.) lines were crossed in a complete diallel scheme and the single-cross hybrids obtained were assessed at four experimental stations of the Agronomic Institute of Campinas, in São Paulo State, Brazil.

Hormones as go-betweens in plant microbiome assembly. [PDF]
Plant J, 2021 Summary The interaction of plants with complex microbial communities is the result of co‐evolution over millions of years and contributed to plant transition and adaptation to land. The ability of plants to be an essential part of complex and highly dynamic ecosystems is dependent on their interaction with diverse microbial communities.

Pest categorisation of Pantoea ananatis
EFSA Journal, Volume 21, Issue 3, March 2023., 2023 Abstract The EFSA Plant Health Panel performed a pest categorisation of Pantoea ananatis, a Gram‐negative bacterium belonging to the Erwiniaceae family. P. ananatis is a well‐defined taxonomic unit; nonetheless, its pathogenic nature is not well defined and non‐pathogenic populations are known to occupy several, very different environmental niches as ...

Plant Breeding, Volume 140, Issue 5, Page 801-811, October 2021., 2021 Abstract Maize white spot (MWS) is one of the most important foliar diseases in Brazil causing significant yield losses. Breeding genotypes with MWS resistance is the most sustainable alternative for managing such losses; however, their genetic control is poorly understood.
