Durable resistance to fungal diseases is largely polygenic and quantitative, with the important exception of mlo resistance to powdery mildew of spring barley.

Resistance to Barley yellow mosaic virus and orange wheat blossom midge has used single genes which have so far been durable.

Wheat resistance to FHB is a complex with five types. Each type of resistance is controlled by multiple quantitative trait loci (QTLs) with most having minor effects and being affected by environments.

The 26 repeatable QTL were located in ~100 Mb intervals based on IWGSC reference sequence map, which will be critical QTLs for functional marker development and for improvement of FHB resistance in breeding. Genomic selection (GS) together with marker-assisted selection (MAS) coupling with phenotypic selection will facilitate accumulation of multiple QTLs from different sources to create highly resistant cultivars.","PeriodicalId":348317,"journal":{"name":"Achieving durable disease resistance in cereals","volume":"31 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-10-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115986927","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Due to an increasing risk of food losses e.g. in barley by Barley yellow dwarf virus (BYDV) as a consequence of climate change, associated by a strong demand to decrease the use of chemical insecticides, breeding for BYDV resistance is of prime importance today. This chapter describes the negative impact of BYDV on barley on multiple levels (anatomy, physiology and agronomic traits). It also demonstrates the benefits of BYDV resistance regarding a reduction in yield losses but also a decreased spread of BYDV in the field due to effects on the tritrophic interaction of virus, vector and plant. Until now, several genes and QTL are known that mediate tolerance or resistance against BYDV, respectively. The combination of genomic tools and phenotyping is the basis for the identification of these genes and recent developments facilitate to enhance this process.","PeriodicalId":348317,"journal":{"name":"Achieving durable disease resistance in cereals","volume":"12 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-10-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126974486","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Recently, STB has been the subject of intensive molecular studies. Notably, massive transcriptomic analyses have helped to explore this particular bi-phasic (asymptomatic/necrotrophic) infection process. Cytological analyses have also improved our understanding of the asymptomatic phase. These advances suggest that Zymoseptoria behaves as a hemi-biotrophic fungus, acting like an endophyte during its asymptomatic phase. STB is still difficult to control. The emergence of fungicide-resistant isolates has reduced the efficacy of many fungicides requiring the development of novel fungicides and methods to counteract/reduce fungicide resistance. Likewise, because Stb-resistant wheat cultivars have all been successively defeated by virulent isolates, there is a need to identify new resistance genes in wheat, and to develop better disease resistance management methods (pyramiding, mixture/alternation) to sustainably control this pathogen.","PeriodicalId":348317,"journal":{"name":"Achieving durable disease resistance in cereals","volume":"19 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-10-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130057020","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Most problematic is Fusarium head blight because grains become contaminated with harmful mycotoxins. Currently Fusarium control using fungicides is only partially effective, whilst cultivars with acceptable resistance levels are scarce. This chapter reviews the recent advances in fundamental knowledge on the cell biology of interactions, the in planta production of trichothecene mycotoxins, Fusarium genomes/pan-genomes, newly discovered Fusarium virulence factors, small secreted effectors, plant defence components and resistance genes underlying major QTLs. These discoveries are discussed in the context of exploiting new intervention targets to achieve control through genetic modification, gene editing and HIGS. Finally, the chapter explores how to develop a more integrated approach that includes marker assisted selection in breeding programmes, removal of susceptibility loci and the inclusion of new approaches arising from plant defence, virulence and effector studies.","PeriodicalId":348317,"journal":{"name":"Achieving durable disease resistance in cereals","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-10-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128715791","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
