“…The potato population used in our study has also been rated for other agricultural and nutritional important traits like macronutrients [ 68 ], sugars [ 54 ], hydroxycinnamic acids (HCAs) [ 69 ], and resistance to late blight caused by the pathogen Phytophtora infestans [ 56 ]. We were interested in evaluating whether some of these traits show phenotypic or genomic correlations with anthocyanin variation.…”

Anthocyanin biosynthesis is one of the most studied pathways in plants due to the important ecological role played by these compounds and the potential health benefits of anthocyanin consumption. Given the interest in identifying new genetic factors underlying anthocyanin content we studied a diverse collection of diploid potatoes by combining a genome-wide association study and pathway-based analyses. By using an expanded SNP dataset, we identified candidate genes that had not been associated with anthocyanin variation in potatoes, namely a Myb transcription factor, a Leucoanthocyanidin dioxygenase gene and a vacuolar membrane protein. Importantly, a genomic region in chromosome 10 harbored the SNPs with strongest associations with anthocyanin content in GWAS. Some of these SNPs were associated with multiple anthocyanin compounds and therefore could underline the existence of pleiotropic genes or anthocyanin biosynthetic clusters. We identified multiple anthocyanin homologs in this genomic region, including four transcription factors and five enzymes that could be governing anthocyanin variation. For instance, a SNP linked to the phenylalanine ammonia-lyase gene, encoding the first enzyme in the phenylpropanoid biosynthetic pathway, was associated with all of the five anthocyanins measured. Finally, we combined a pathway analysis and GWAS of other agronomic traits to identify pathways related to anthocyanin biosynthesis in potatoes. We found that methionine metabolism and the production of sugars and hydroxycinnamic acids are genetically correlated to anthocyanin biosynthesis. The results contribute to the understanding of anthocyanins regulation in potatoes and can be used in future breeding programs focused on nutraceutical food.

“…Recent evidence suggests that the Solanum tuberosum Group Phureja, a cultivated potato group, which is mainly comprised of diploid genotypes, contains higher nutritional value than other potato species [8][9][10]. These potatoes possess a wide variability in important nutritional traits, flesh and skin colors from yellow to purple [8,[11][12][13], and contain health-promoting compounds such as polyphenols, including anthocyanins, and carotenoids [14][15][16][17]. In recent years, there has been an increasing interest in potatoes with red and purple flesh or skin, and they have attracted the attention of researchers, as well as consumers, due to their antioxidant properties, taste, and appearance [18][19][20][21].…”

“…Like other phenolic compounds, anthocyanins are involved in a series of essential biological processes, such as antioxidative protection against reactive oxygen species and in signaling the response to biotic and abiotic stresses [27]. Some studies have also reported the potential health benefits of consuming anthocyanin-pigmented potatoes to provide protection against several diseases [3,15,[28][29][30]. Given the substantial variation of levels of anthocyanins in tubers [22,[31][32][33][34] from potato landraces, it should be possible to exploit this genetic diversity using marker-assisted selection programs that target specific anthocyanins.…”

Chromosomes I and X Harbor Consistent Genetic Factors Associated with the Anthocyanin Variation in Potato

et al. 2019

Potatoes are an important staple food worldwide and are the third main source of antioxidants in the human diet. One of the most important antioxidant compounds in potatoes is the anthocyanin pigments. Some reports indicate a high positive correlation between color intensity, anthocyanins content, and antioxidant level in potato tubers. The variation in anthocyanins composition and content in potato tubers among diverse germplasm sources has important nutritional and health implications and constitutes an interesting trait for potato breeding programs focused on enhancing the anthocyanin and antioxidant contents of potato materials. We identified and quantified five anthocyanidins (delphinidin, cyanidin, petunidin, pelargonidin, and peonidin) on tubers from the Colombian germplasm collection of Solanum tuberosum L. Group Phureja. The phenotypic data were merged into a genome-wide association study in order to identify genomic regions associated with the nutritional compounds’ variation in potatoes. The association was conducted using a 7520 single nucleotide polymorphisms markers matrix. Seven quantitative trait loci were identified. Chromosomes I and X harbored the most stable quantitative trait loci (QTL). Three quantitative trait loci were identified close to previously reported genes involved in the regulation of anthocyanins in potato tubers. The genomic regions of these QTL reveal presumptive candidate genes as genetic factors that are the basis for a better understanding of the genetic architecture of the regulation of nutritional compounds in potatoes.

“…The yield of these varieties in average is 30 t/ha and the potential to increase farmer´s income is 18% and they present higher resistance to late blight [21,22]. This disease is the most devastating disease in potato [23][24][25] and the novelty is their better nutritional contents especially iron and zinc [26], protein [27], and antioxidants compounds [28]. It shows at the top the relevance of the shared vision project, for designing a comprehensive approach for scaling up.…”

A Model to Promote Sustainable Social Change Based on the Scaling up of a High-Impact Technical Innovation

2018

The scaling up of the innovations concept has gained importance in recent years, underlining the importance of disseminating successful innovations on a large scale to increase their socio-economic impact, seeking to sustain broad rural development and promoting public policies that generate equal and sustainable results. However, few projects take advantage of the adoption of innovative technologies to promote social change. This paper reports on an intervention model that incorporates common elements, from the literature, of scaling up, and includes novel such as linking technological and social innovations, with an exit strategy to build sustainable processes and results. The model is based on a trans-disciplinary approach, and leadership, that involves local communities and stakeholders to establish synergies, to give coherence to the whole process, and to build an exit strategy involving territorial dynamics related to the innovation. The model includes a clear definition of the objects, and the process, that should be transformed, and the specific methodologies to involve local communities and stakeholders, to reach the final target user. The model was applied to develop the project, More Nutritious Potatoes, for scaling up new yellow potatoes varieties with improved agronomic and nutritional attributes. To implement the project, the research team, local communities, and stakeholders agreed on specific actions to improve food security and nutrition in a sustainable manner. The operational objectives were, the strengthening of capabilities for autonomy and governance in public policies, the entrepreneurship to build inclusive businesses, the valorization of agro-biodiversity, the acquisition of good food habits, and the promotion of social equity. The methodologies employed allowed building of social and scientific capabilities for Colombia.
