“…Fungusun eşeyli dönemi henüz rapor edilmemiştir [32]. Zymoseptoria tritici veya Dothistroma septosporum gibi yakından ilişkili diğer funguslardan farklı olarak, R. collo-cygni, endofitik fungusların çeşitli özelliklerini de göstermektedir [33,34].…”

Ramularia collo-cygni, arpada (Hordeum vulgare) Ramularia yaprak lekesi hastalığına neden olan fungal bir etmendir. Nekrotik lekelenmeye ve erken yaprak yaşlanmasına neden olarak arpada yeşil yaprak alanı kaybına yol açmakta ve epidemi yapması durumunda %70'e varan verim kaybına neden olmaktadır. Hastalığın geç dönemde ortaya çıkması ve etmenin tanısının zorluğu nedeni ile yüz yıldan fazla süre önce tanımlanmış olmasına rağmen son yıllarda, arpanın önemli bir patojeni olarak kabul edilmiştir. Günümüzde dünya çapında meydana getirdiği epidemiler nedeni ile araştırmacılar tarafından oldukça ilgi görmektedir. Bu derleme, ülkemizde henüz tespiti yapılmamış olan bu fungal etmenin detaylı olarak biyolojisi, epidemiyolojisi, konukçu patojen ilişkilerini tanımlamakta ve mevcut kontrol stratejilerini özetlemektedir.

“…This recombination facilitates the emergence of resistance to fungicides and to major resistance genes, leading to an erosion of their efficiency. [7][8][9] The use of bioregulation agents has been successful in several crop-pest systems 10 and could be an alternative to conventional control methods. Microbial antagonist agents such as fungi and bacteria are prime candidates against fungal plant pathogens 11 including against Z. tritici during its epidemic phase, that is, during the growing season when the disease significantly affects plant growth.…”

BACKGROUNDSeptoria tritici blotch (STB), caused by the fungus Zymoseptoria tritici, is a foliar disease affecting wheat crops against which conventional control methods are not totally effective. During inter‐epidemic periods the fungus survives in wheat residues left on the ground. In this study, we tested the potential of the collembolan Heteromurus nitidus – a springtail species present in field soils and known to interact with different fungal species – as a potential bioregulation agent of Z. tritici on wheat residues through a choice and consumption experiment.RESULTSSpringtails preferred inoculated fresh residues but did not have a preference between inoculated and uninoculated old residues. Springtails grazed on Z. tritici fruiting bodies and reduced pycnidiospore numbers by ten‐fold compared to control inoculated fresh residues. Attraction toward fresh inoculated residues and pycnidiospore reduction support the hypothesis that Z. tritici is a food source for springtails. H. nitidus showed no preference between inoculated and uninoculated 18‐month‐old residues, probably because they no longer produced ascospores.CONCLUSIONAttraction towards fresh residues and spore reduction support our hypothesis that H. nitidus may contribute to the bioregulation of Z. tritici. Perspectives for field application would be determined by the ability of H. nitidus and Z. tritici to interact at key epidemiological stages. The impact of H. nitidus on the quantity of pathogen primary inoculum over time should be estimated using residues of intermediate age. This would help to identify the optimal period for enhancing the effectiveness of springtails as consumers of Z. tritici.This article is protected by copyright. All rights reserved.

“…Several Dothideomycetes affect crops used as staple food around the world. To list only a few, Zymoseptoria tritici (teleomorph Mycosphaerella graminicola) and Dreschlera tritici-repentis (teleomorph Pyrenophora tritici-repentis), the causative agents of Septoria tritici blotch and tan spot, respectively, are major pathogens of wheat worldwide [20,21], and black Sigatoka disease caused by Pseudocercospora fijiensis (teleomorph Mycosphaerella fijiensis) remains a threat to banana production in many countries [22,23]. Given that all climate change models forecast an increase in abiotic stress to crops around the world and that these stresses have an impact on plant-pathogen interactions, it is important to understand how abiotic stresses can affect disease prevalence and severity.…”

Does Abiotic Host Stress Favour Dothideomycete-Induced Disease Development?

Dothideomycetes represent one of the largest and diverse class of fungi. This class exhibits a wide diversity of lifestyles, including endophytic, saprophytic, pathogenic and parasitic organisms. Plant pathogenic fungi are particularly common within the Dothideomycetes and are primarily found within the orders of Pleosporales, Botryosphaeriales and Capnodiales. As many Dothideomycetes can infect crops used as staple foods around the world, such as rice, wheat, maize or banana, this class of fungi is highly relevant to food security. In the context of climate change, food security faces unprecedented pressure. The benefits of a more plant-based diet to both health and climate have long been established, therefore the demand for crop production is expected to increase. Further adding pressure on food security, both the prevalence of diseases caused by fungi and the yield losses associated with abiotic stresses on crops are forecast to increase in all climate change scenarios. Furthermore, abiotic stresses can greatly influence the outcome of the host-pathogen interaction. This review focuses on the impact of abiotic stresses on the host in the development of diseases caused by Dothideomycete fungi.
