    Potato scab (Streptomyces scabies) is widespread in all potato growing regions, and it significantly reduces potato quality and marketability. Drought, as an abiotic stress, is a major threat to crop productivity. Currently, the genome-wide architecture of the genetic control of these two traits are limited in potato. Here, we used a genome-wide association studies on a 384 diploid potato germplasm panel to determine the potato genomic regions and the genes potentially associated with resistance to scab and drought. Here, we show that three candidate genes located in a 0.5- 5 kb genomic region of chromosome 7 are associated with scab resistance. Furthermore, two major QTNs located on chromosome 5, explained by 16 and 32% of phenotypic variations were found associated with 25 candidate genes. The data will be presented and discussed in a context of global changing climate.

    Powdery mildew (PM) is an obligate biotrophic fungus (Podosphaera lini) causing high yield loss to flax (Linum usitatissimum L.). To date, no PM resistance genes have been fully functionally characterized. Using GWAS, we identified a locus harboring three flax homologs of the Arabidopsis RPW8 genes that confer broad-spectrum resistance to powdery mildew. Here, we characterized the gene expression profile of the three RPW8 candidate genes following PM inoculation. The data showed that, similar to RPW8.2 acting through the salicylic acid (SA) signaling pathway, the RPW8 homologs Lus10000835 and Lus10000836 are highly expressed in resistant flax lines compared to the suscpetible lines. In contrast, the flax RPW8 homolog Lus10009328 was highly expressed in the susceptible lines, suggesting a different signaling pathway from the other two homologs. RPW8.1 has been shown to activate ethylene signaling through aminocyclopropane-1-carboxylate oxidase gene isoform 4 (ACO4) and, this elevated ethylene negatively regulates the expression of RPW8.1, thereby attenuating its mediated-cell death and disease resistance when no disease is present to avoid unnecessary defense responses. We conclude that PM resistance induced by RPW8 in flax may mainly be activated through SA signaling pathways, and perhaps similarly to the ethylene signaling in Arabidopsis.

  16. Potato greening: gaining an understanding through ‘omics approaches
    K. Dougherty1, T. F. Mitterboeck1*, M. Lague1, M. Zaidi2, B. Bizimungu1, and B. Fofana2. 1Agriculture and Agri-Food Canada, Fredericton, New Brunswick, Canada E3B 4Z7 (e-mail:fatima.mitterboeck@agr.gc.ca); and 2Agriculture and Agri-Food Canada, Charlottetown, Prince Edward Island, Canada C1A 4N6.

    Potato ‘greening’ occurs when tubers are exposed to light, and results from a de novo synthesis of chlorophyll and a simultaneous formation of steroidal glycoalkaloids, which are toxic to humans and animals. Potato is the largest vegetable crop in Canada, and this greening causes substantial loss of products. Currently, there are no potato cultivars that are resistant to light–induced greening available on the market. The goal of this study is to understand the genetic components and molecular mechanisms of light-induced greening, and to use this knowledge to develop gene-editing tools to generate cultivars resistant to greening. From a core germplasm collection of over 800 mutant potato clones, two clones were observed to be tolerant to light-induced greening. These two non-greening clones, along with a greening control, underwent whole genome sequencing as well as transcriptomic sequencing after light exposure. Here, we will show our findings on single nucleotide polymorphisms (SNPs) and structural variants (SV) that differentiate the non-greening from greening clones. Deploying the non-greening trait into popular potato cultivars would be of high interest to the industry and stakeholders both for tuber appearance, quality, safety, marketability, and food waste reduction.

    Potato is the largest vegetable crop in Canada, with an export value of $1.8B in 2019. As a major food source, potato nutritional quality and safety are critical for the public health. Potato greening, also known as potato sunburn, causes 2-3% loss at the farm gate and up to 17% during postharvest and retail storage. It results from a de novo synthesis of chlorophyll in the cortical parenchyma cells under the periderm after light exposure and leads to a simultaneous formation of toxic steroidal glycoalkaloids (SGAs). Whereas chlorophyll itself is not a health hazard, SGAs are toxic to humans and animals. Development of potato cultivars that are resistant to light-induced greening is a viable strategy for an economic and environmental sustainability. We will present and discuss our approach and preliminary results towards an understanding of the tuber greening phenomenon in potato.

  18. Mutational Genetics In Diploid Potato In The CRISPR Era

    Cultivated potato (Solanum tuberosum L.) is the fourth most consumed food crop after rice wheat and maize. Cultivated potato is a clonally propagated, autotetraploid crop species with a narrow genetic diversity. Its highly heterozygous, complex genome, and tetrasomic inheritance make its genetic studies and improvement more difficult than grain crops. Recently, diploid potato breeding has regained an interest in the potato genetics community. Genetically, diploid potatoes are easy to work with, can be used as gene donors in the breeding process of cultivated potatoes, and can also be grown on their own as varieties. However, diploid breeding continuum faces many challenges including anti-nutritional factors and self-incompatibilities. Mutations are known as the key drivers for evolution and diversification in plants. In breeding and varietal selection, sources for variation are always sought as starting materials, and in the absence of desired natural variations in breeding populations, targeted or random mutagenesis is applied to induce variations. Recently, a mutagenized pre-breeding diploid potato population was developed at AAFC Charlottetown. Dr. Fofana will give an update on this genetic resource, its characterization, and its potentials in the CRISPR era.
