“…In light of the limitations of the above-mentioned methods, a more refined method known as "inclusive composite interval mapping" was proposed and implemented in the QTLIciMapping 4.2.53 (http://www.isbreeding.net/ (latest released in September 2019, accessed on 2 February 2022) which is considered as the most modern method of QTL detection [47]. We have recently detected several QTLs for Fusarium head blight [85] and seed longevity [50] in wheat and germination-related traits in tobacco [86] by applying the QTLIciMapping tool. Therefore, we convened the IciMapping 4.2.53 to detect the putative additive QTLs of the traits under consideration by applying the inclusive composite interval mapping (ICIM) command where 1.0 cM was the walking speed.…”

The size, shape, and color of wheat seeds are important traits that are associated with yield and flour quality (size, shape), nutritional value, and pre-harvest sprouting (coat color). These traits are under multigenic control, and to dissect their molecular and genetic basis, quantitative trait loci (QTL) analysis is used. We evaluated 114 recombinant inbred lines (RILs) in a bi-parental RIL mapping population (the International Triticeae Mapping Initiative, ITMI/MP) grown in 2014 season. We used digital image analysis for seed phenotyping and obtained data for seven traits describing seed size and shape and 48 traits of seed coat color. We identified 212 additive and 34 pairs of epistatic QTLs on all the chromosomes of wheat genome except chromosomes 1A and 5D. Many QTLs were overlapping. We demonstrated that the overlap between QTL regions was low for seed size/shape traits and high for coat color traits. Using the literature and KEGG data, we identified sets of genes in Arabidopsis and rice from the networks controlling seed size and color. Further, we identified 29 and 14 candidate genes for seed size-related loci and for loci associated with seed coat color, respectively.

“…On chromosome 10, the most important candidate genes include putative histone H3.3-like (associated with SNP S10_374592 and multiple seed storage durations) and high mobility group B protein 6 (associated with SNP S10_16302829 ). Histone H3.3-like is a candidate gene for longevity in wheat [ 3 ], whereas the gene encoding the “ high-mobility group B protein 6 ” is a WRKY transcription factor involved in the nucleosome/chromatin assembly [ 62 ].…”

Seed longevity is the most important trait in the genebank management system. No seed can remain infinitely viable. There are 1241 accessions of Capsicum annuum L. available at the German Federal ex situ genebank at IPK Gatersleben. C. annuum (Capsicum) is the most economically important species of the genus Capsicum. So far, there is no report that has addressed the genetic basis of seed longevity in Capsicum. Here, we convened a total of 1152 Capsicum accessions that were deposited in Gatersleben over forty years (from 1976 to 2017) and assessed their longevity by analyzing the standard germination percentage after 5–40 years of storage at −15/−18 °C. These data were used to determine the genetic causes of seed longevity, along with 23,462 single nucleotide polymorphism (SNP) markers covering all of the 12 Capsicum chromosomes. Using the association-mapping approach, we identified a total of 224 marker trait associations (MTAs) (34, 25, 31, 35, 39, 7, 21 and 32 MTAs after 5-, 10-, 15-, 20-, 25-, 30-, 35- and 40-year storage intervals) on all the Capsicum chromosomes. Several candidate genes were identified using the blast analysis of SNPs, and these candidate genes are discussed.

“…For example, aldo-keto reductases (AKR) have been shown to degrade DON in microbes [ 50 ]. While there is no evidence to date that AKRs degrade DON in wheat, genes encoding AKRs were linked with a FHB resistance QTL on chromosome 3B of wheat [ 51 ].…”

Trichothecenes and Fumonisins: Key Players in Fusarium–Cereal Ecosystem Interactions

Fusarium fungi produce a diverse array of mycotoxic metabolites during the pathogenesis of cereals. Some, such as the trichothecenes and fumonisins, are phytotoxic, acting as non-proteinaceous effectors that facilitate disease development in cereals. Over the last few decades, we have gained some depth of understanding as to how trichothecenes and fumonisins interact with plant cells and how plants deploy mycotoxin detoxification and resistance strategies to defend themselves against the producer fungi. The cereal-mycotoxin interaction is part of a co-evolutionary dance between Fusarium and cereals, as evidenced by a trichothecene-responsive, taxonomically restricted, cereal gene competing with a fungal effector protein and enhancing tolerance to the trichothecene and resistance to DON-producing F. graminearum. But the binary fungal–plant interaction is part of a bigger ecosystem wherein other microbes and insects have been shown to interact with fungal mycotoxins, directly or indirectly through host plants. We are only beginning to unravel the extent to which trichothecenes, fumonisins and other mycotoxins play a role in fungal-ecosystem interactions. We now have tools to determine how, when and where mycotoxins impact and are impacted by the microbiome and microfauna. As more mycotoxins are described, research into their individual and synergistic toxicity and their interactions with the crop ecosystem will give insights into how we can holistically breed for and cultivate healthy crops.
