February 1, 2024 : The SweetGAINS Project is pleased to make available the haplotype-resolved chromosome-scale genome assembly and annotation of I. batatas Tanzania (v2) and I. batatas New Kawogo (v2) under a pre-publication data release policy. An updated genome assembly and annotation for I. batatas Beauregard (v3) is also available the pre-publication data release policy.
September 12, 2022 : The search tools (Functional annotation, Interpro, Gene Ontology, and PFAM) have been updated with results for Ipomoea batatas Beauregard v1. The search results also have links to the updated Gene Annotation Report pages.
August 10, 2022: The Ipomoea batatas Beauregard v1 genome assembly and annotation is now available for searches with the BLAST search tool. We have also released a new Jbrowse2 instance for browsing the genome annotation and RNA-seq data.
July 20, 2022: The SweetGAINS Project is pleased to make available the haplotype-resolved chromosome-scale genome assembly of I. batatas Beauregard under a pre-publication data release policy. For more information please see the Ipomoea batatas Beauregard Genome Assembly and Annotation download page.
November 2, 2018: The paper "Genome sequences of two diploid wild relatives of cultivated sweetpotato reveal targets for genetic improvement" by Wu et al. was published in Nature Communications. (https://doi.org/10.1038/s41467-018-06983-8).
October 11, 2018: The paper "Transcriptomic analysis of sweet potato under dehydration stress identifies candidate genes for drought tolerance" by Lau et al. was published in Plant Direct. (https://doi.org/10.1002/pld3.92).
April 18, 2018 The Ipomoea e-PCR tool has been released. The Ipomoea e-PCR tool performs an in-silico PCR simulation (e-PCR) using the diploid Ipomoea pseudomolecules.
August 11, 2017: The FPKM matrix for 15 abiotic and biotic stress RNA-seq libraries is available on the GT4SP Project Download Page. RNA-seq coverage tracks for these libraries are also available on the I. trifida and I. triloba genome browsers. Tracks for putative SSRs and alignments of the DM potato, Arabidopsis, morning glory (I. nil), and tomato proteins have also been added to the genome browsers.
April 17, 2017: The I. trifida and I. triloba pseudomolecules and annotation were released. The SPGR web tools, BLAST server, genome browser, and GT4SP download page were updated.
August 1, 2016: The Sweetpotato Genomics Resource was released.
July 4, 2016: Four researchers including two from the GT4SP project were awarded the World Food Prize for work on developing orange-fleshed sweetpotato.
