Characterizing North American Ipomoea grandifolia (Convolvulaceae), a member of Ipomoea series batatas
<p>Species in the genus <em>Ipomoea </em>are often difficult to identify due to their similar morphologies and their ability to hybridize with one another. An undescribed North American <em>Ipomoea </em>morphotype in series <em>Batatas</em>, referred here as <em>Ipomoea</em> Carolina morphotype, was found to be morphologically, genetically, and reproductively isolated from other locally co-occurring <em>Ipomoea </em>species. A previous phylogenetic analysis that included a broader sampling of species in <em>Ipomoea</em> series <em>Batatas</em> suggested that <em>Ipomoea </em>Carolina morphotype may be <em>Ipomoea grandifolia</em>, a species described as found only in South America<em>.</em> To evaluate these findings, we tested intrinsic cross-compatibility between <em>Ipomoea </em>Carolina morphotype and <em>I. grandifolia</em> as well as with three other co-localizing North American <em>Ipomoea </em>species – <em>Ipomoea cordatotriloba</em>,<em> Ipomoea lacunosa</em>, and <em>Ipomoea leucantha</em>. We also examined genetic differentiation using single nucleotide polymorphisms from leaf transcriptomes from multiple individuals of all five species and several outgroup species. We find no cross-incompatibility and little genetic differentiation between <em>Ipomoea </em>Carolina morphotype and <em>Ipomoea grandifolia</em>, suggesting that<em> Ipomoea </em>Carolina morphotype is a representative of <em>Ipomoea grandifolia</em>. This finding raises additional questions about the origins of <em>Ipomoea grandifolia</em> in North America and how its disjunct distribution could play a role in the divergence of <em>Ipomoea grandifolia</em> in the future.</p>

Replication data for: Consumer preference testing of boiled sweetpotato (Ipomoea batatas (L.) Lam.) using crowdsourced citizen science in Ghana and Uganda
<p>Crowdsourced citizen science is an emerging approach in plant sciences. The triadic comparison of technologies (tricot) approach has been successfully utilised by demand-led breeding programmes to identify varieties for dissemination suited to specific geographic and climatic regions. An important feature of this approach is the independent way in which farmers individually evaluate the varieties on their own farms as ‘citizen scientists’. In this study, we adapted this approach to evaluate consumer preferences to boiled sweetpotato (<em>Ipomoea batatas</em> (L.) Lam) roots of 21 advanced breeding materials and varieties in Ghana and 6 released varieties in Uganda. We were specifically interested in evaluating if a more independent style of evaluation (home tasting) would produce results comparable to an approach that involves control over preparation (centralised tasting). We compiled data from 1,433 participants who individually contributed to a home tasting (de-centralised) and a centralised tasting trial in Ghana and Uganda, evaluating overall acceptability, and indicating the reasons for their preferences. Geographic factors showed important contribution to define consumers’ preference to boiled sweetpotato genotypes. Home and centralised tasting approaches gave similar rankings for overall acceptability, which was strongly correlated to taste. In both Ghana and Uganda, it was possible to robustly identify superior sweetpotato genotypes from consumers’ perspectives. Our results indicate that the tricot approach can be successfully applied to consumer preference studies.</p>
Data from: On the origin of sweet potato (Ipomoea batatas (L.) Lam) genetic diversity in New Guinea, a secondary centre of diversity
New Guinea is considered the most important secondary centre of diversity for sweet potato (Ipomoea batatas). We analysed nuclear and chloroplast genetic diversity of 417 New Guinea sweet potato landraces, representing agro-morphological diversity collected throughout the island, and compared this diversity with that in tropical America. The molecular data reveal moderate diversity across all accessions analysed, lower than that found in tropical America. Nuclear data confirm previous results, suggesting that New Guinea landraces are principally derived from the Northern neotropical genepool (Camote and Batata lines, from the Caribbean and Central America). However, chloroplast data suggest that South American clones (early Kumara line clones or, more probably, later reintroductions) were also introduced into New Guinea and then recombined with existing genotypes. The frequency distribution of pairwise distances between New Guinea landraces suggests that sexual reproduction, rather than somaclonal variation, has played a predominant role in the diversification of sweet potato. The frequent incorporation of plants issued from true seed by farmers, and the geographical and cultural barriers constraining crop diffusion in this topographically and linguistically heterogeneous island, has led to the accumulation of an impressive number of variants. As the diversification of sweet potato in New Guinea is primarily the result of farmers' management of the reproductive biology of their crop, we argue that on-farm conservation programmes that implement distribution of core samples (clones representing the useful diversity of the species) and promote on-farm selection of locally adapted variants may allow local communities to fashion relatively autonomous strategies for coping with ongoing global change.
