Abstract— Species in the genus Ipomoea are often difficult to identify due to their similar morphologies and their ability to hybridize with one another. An undescribed North American Ipomoea morphotype in Ipomoea series Batatas , referred here as Ipomoea Carolina morphotype, was found to be morphologically, genetically, and reproductively isolated from other locally co-occurring Ipomoea species. A previous phylogenetic analysis that included a broader sampling of species in Ipomoea series Batatas suggested that Ipomoea Carolina morphotype may be Ipomoea grandifolia , a species described as found only in South America. To evaluate these findings, we tested intrinsic cross-compatibility between Ipomoea Carolina morphotype and I. grandifolia as well as with three other co-localizing North American Ipomoea species: Ipomoea cordatotriloba , Ipomoea lacunosa , and Ipomoea leucantha . 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 Ipomoea Carolina morphotype and Ipomoea grandifolia , suggesting that Ipomoea Carolina morphotype is a representative of Ipomoea grandifolia . This finding raises additional questions about the origins of Ipomoea grandifolia in North America and how its disjunct distribution could play a role in the divergence of Ipomoea grandifolia in the future.

This article reviews the patents that have been presented over the past two decades related to alternative functional use of the Sweet potato, Ipomoea batatas (L.) Lam. The major categories of available patents include alternative food products such as Sweet potato chips and fries, Sweet potato ornamental products, and fuel ethanol production from Sweet potato. The majority of recent patents fall under the category of ornamental products and alternative food products, with only a few fuel ethanol products. Figure 1 shows the major categories of patented alternative products from Sweet potato.

The physicochemical characteristics offive sweet potato varieties were studied and compared to potato starch. The parameters studied were starch yield, amylose content, proximate content, swelling power and solubility and yneresis. The starch content offive sweet potato varieties ranged between 23.21Yrr 29.7% The Ipomoea batatas variety 4 gave the highest yield of starch (29.7%) while Ipomoea batatas variety 3 gave the lowest yield (23.2%). The amylose contents ranged between 20. J3lYrr 25.73% Amylose content of Ipomoe~ batatas variety 5 was the highest (25.73%) while starch from Ipomoea batatas showed the lowest amylose content (20.13%). The moisture contents ranged were 8. 761Yrr9. 05% The moisture content of Ipomoea batatas variety 4 was the highest (9.05%) and the lowest was Ipomoea batatas variety 1 (8.76%). The ash content varied between 0.47IYrrO.52% Ipomoea batatas variety 3 showed the highest ash content (0.52%) and the lowest ash content was found for Ipomoea batatas variety 4 (0.47%). The lipid content varied between o. 091YrrO. 12% Ipomoea batatas variety 2 gave the highest lipid content (0.12%) while the lowest was found for Ipomoea batatas variety 3 (0.09%). The protein contents were in the range of o. 171YrrO. 19% Ipomoea batatas variety 4 gave the highest protein content (0.19%) while Ipomoea batatas variety 1 gave the lowest protein content (0.17%). The swelling power ofIpomoea batatas variety 3 starch was the highest among all samples of sweet potato starches at all the temperature ranged studied while Ipomoea batatas variety 5 showed the lowest swelling power. For solubility, it was found that Ipomoea batatas variety 5 showed the
highest solubility and the lowest wasfoundfor Ipomoea batatas variety 3 at all the temperature ranged studied. Syneresis for Ipomoea batatas variety 5 starch was the highest while Ipomoea batatas had the lowest value ofsyneresis tendency among the sweet potato starches studied.

Abstract Background As a major family of plant-specific transcription factors, SQUAMOSA PROMOTER BINDING PROTEIN-LIKE (SPL) genes play crucial regulatory roles in plant growth, development, and stress tolerance. SPL transcription factor family has been widely studied in various plant species, however, there are no systematic studies on SPL genes in genus Ipomoea . Results In this study, a total of 29, 27, 26, 23 SPL genes were identified in Ipomoea batatas , Ipomoea trifida , Ipomoea triloba , and Ipomoea nil , respectively. Phylogenetic analysis indicated that Ipomoea SPL genes could be clustered into eight clades. SPL members within the same clade showed similar gene structures, domain organizations, and cis-acting element compositions, suggesting similarity of biological function potentially. Evolutionary analysis revealed that segmental duplication events played a major role in the Ipomoea genus-specific expansion of SPL genes. Of these Ipomoea SPL genes, 69 were predicted as the target genes of miR156, and 7 IbSPL genes were further confirmed by degradome data. Additionally, IbSPL genes showed diverse expression patterns in various tissues, implying their functional conservation and divergence. Finally, by combining the information from expression patterns and regulatory sub-networks, we found that four IbSPL genes ( IbSPL16 / IbSPL17 / IbSPL21 / IbSPL28 ) may be involved in the formation and development of storage roots. Conclusions This study not only provides novel insights into the evolutionary and functional divergence of the SPL genes in all available sequenced species in genus Ipomoea , but also lays a foundation for further elucidation of the potential functional roles of IbSPL genes during storage root development.

As a major plant-specific transcription factor family, SPL genes play a crucial role in plant growth, development, and stress tolerance. The SPL transcription factor family has been widely studied in various plant species; however, systematic studies on SPL genes in the genus Ipomoea are lacking. Here, we identified a total of 29, 27, 26, and 23 SPLs in Ipomoea batatas, Ipomoea trifida, Ipomoea triloba, and Ipomoea nil, respectively. Based on the phylogenetic analysis of SPL proteins from model plants, the Ipomoea SPLs were classified into eight clades, which included conserved gene structures, domain organizations and motif compositions. Moreover, segmental duplication, which is derived from the Ipomoea lineage-specific whole-genome triplication event, was speculated to have a predominant role in Ipomoea SPL expansion. Particularly, tandem duplication was primarily responsible for the expansion of SPL subclades IV-b and IV-c. Furthermore, 25 interspecific orthologous groups were identified in Ipomoea, rice, Arabidopsis, and tomato. These findings support the expansion of SPLs in Ipomoea genus, with most of the SPLs being evolutionarily conserved. Of the 105 Ipomoea SPLs, 69 were predicted to be the targets of miR156, with seven IbSPLs being further verified as targets using degradome-seq data. Using transcriptomic data from aboveground and underground sweet potato tissues, IbSPLs showed diverse expression patterns, including seven highly expressed IbSPLs in the underground tissues. Furthermore, the expression of 11 IbSPLs was validated using qRT-PCR, and two (IbSPL17/IbSPL28) showed significantly increased expression during root development. Additionally, the qRT-PCR analysis revealed that six IbSPLs were strongly induced in the roots under phytohormone treatments, particularly zeatin and abscisic acid. Finally, the transcriptomic data of storage roots from 88 sweet potato accessions were used for weighted gene co-expression network analysis, which revealed four IbSPLs (IbSPL16/IbSPL17/IbSPL21/IbSPL28) clusters with genes involved in "regulation of root morphogenesis," "cell division," "cytoskeleton organization," and "plant-type cell wall organization or biogenesis," indicating their potential role in storage root development. This study not only provides novel insights into the evolutionary and functional divergence of the SPLs in the genus Ipomoea but also lays a foundation for further elucidation of the potential functional roles of IbSPLs on storage root development.
