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.

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 ...

Multi‐parental QTL mapping of resistance to white spot of maize (Zea mays) in southern Brazil and relationship to QTLs of other foliar diseases

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.

Severity of leaf diseases in maize inbred lines with different kernel hardness in two sowing seasons

Semina: Ciências Agrárias, 2018
Resistance of maize inbred lines to major leaf diseases should be characterized for the development of new hybrids in breeding programs. Thus, this study aimed to assess the severity of leaf diseases in maize inbredlines with different kernel hardnessand

Detecting the Early Stage of Phaeosphaeria Leaf Spot Infestations in Maize Crop Using In Situ Hyperspectral Data and Guided Regularized Random Forest Algorithm

Journal of Spectroscopy, Volume 2017, Issue 1, 2017., 2017
Phaeosphaeria leaf spot (PLS) is considered one of the major diseases that threaten the stability of maize production in tropical and subtropical African regions. The objective of the present study was to investigate the use of hyperspectral data in detecting the early stage of PLS in tropical maize. Field data were collected from healthy and the early
