Kõrreliste helelaiksuse tekitaja Zymoseptoria tritici fungitsiidiresistentsus

, 2021
Populaarse toiduteravilja nisu olulist saagikuse langust põhjustab kõrreliste helelaiksus, mida põhjustab patogeen Zymoseptoria tritici. Fungitsiidide kasutamine aitab pärssida patogeenide elutegevust ja levikut. Peamiselt kasutatakse Z. tritici tõrjeks fungitsiidirühmadest asoole, suktsinaatdehüdrogenaasi inhibiitoreid ja strobiluriine. Töö eesmärgiks

Surfactin Protects Wheat against Zymoseptoria tritici and Activates Both Salicylic Acid- and Jasmonic Acid-Dependent Defense Responses

Agriculture, 2018
Natural elicitors induce plant resistance against a broad spectrum of diseases, and are currently among the most promising biocontrol tools. The present study focuses on the elicitor properties of the cyclic lipopeptide surfactin on wheat, in order to ...

Deregulation of Plant Cell Death Through Disruption of Chloroplast Functionality Affects Asexual Sporulation of Zymoseptoria tritici on Wheat

Molecular Plant-Microbe Interactions, 2015
Chloroplasts have a critical role in plant defense as sites for the biosynthesis of the signaling compounds salicylic acid (SA), jasmonic acid (JA), and nitric oxide (NO) and as major sites of reactive oxygen species production.

Identification of factors involved in dimorphism and pathogenicity of Zymoseptoria tritici

PLOS ONE, 2017
A forward genetics approach was applied in order to investigate the molecular basis of morphological transition in the wheat pathogenic fungus Zymoseptoria tritici. Z. tritici is a dimorphic plant pathogen displaying environmentally regulated morphogenetic transition between yeast-like and hyphal growth. Considering the infection mode of Z.

Cell biology of Zymoseptoria tritici : Pathogen cell organization and wheat infection

Fungal Genetics and Biology, 2015
Cell biological research in the wheat pathogen Zymoseptoria tritici (formerly Mycosphaerella graminicola) has led to a good understanding of the histology of the infection process. Expression profiling and bioinformatic approaches, combined with molecular studies on signaling pathways, effectors and potential necrosis factors provides first insight ...

Responses to Temperature Shocks in Zymoseptoria tritici Reveal Specific Transcriptional Reprogramming and Novel Candidate Genes for Thermal Adaptation.

Phytopathology
Pathogens' responses to sudden temperature fluctuations, spanning various temporal scales, are critical determinants of their survival, growth, reproduction, and homeostasis.

Modeling Foliar Infection Dynamics in Wheat Using a SEIR Framework: Effects of Seed Treatment and Foliar Fungicide Under Mediterranean Conditions

Agrochemicals
The foliar pathogens of wheat, particularly Zymoseptoria tritici and Pyrenophora tritici-repentis, represent a significant threat to yield. We used a SEIR (Susceptible–Exposed–Infected–Removed) model to quantify epidemic dynamics based on different ...

The ZtvelB Gene Is Required for Vegetative Growth and Sporulation in the Wheat Pathogen Zymoseptoria tritici

Frontiers in Microbiology, 2019
The ascomycete fungus Zymoseptoria tritici is the causal agent of Septoria Tritici Blotch (STB), a major disease of wheat across Europe. Current understanding of the genetic components and the environmental cues which influence development and ...
