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 ONE
Leaf 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]

Tropical Plant Pathology, 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

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 Pathol
The 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

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.
