    The genome of potato, a major global food crop, was recently sequenced. The work presented here details the integration of the potato reference genome (DM) with a new sequence-tagged site marker-based linkage map and other physical and genetic maps of potato and the closely related species tomato. Primary anchoring of the DM genome assembly was accomplished by the use of a diploid segregating population, which was genotyped with several types of molecular genetic markers to construct a new similar to 936 cM linkage map comprising 2469 marker loci. In silico anchoring approaches used genetic and physical maps from the diploid potato genotype RH89-039-16 (RH) and tomato. This combined approach has allowed 951 superscaffolds to be ordered into pseudomolecules corresponding to the 12 potato chromosomes. These pseudomolecules represent 674 Mb (similar to 93%) of the 723 Mb genome assembly and 37,482 (similar to 96%) of the 39,031 predicted genes. The superscaffold order and orientation within the pseudomolecules are closely collinear with independently constructed high density linkage maps. Comparisons between marker distribution and physical location reveal regions of greater and lesser recombination, as well as regions exhibiting significant segregation distortion. The work presented here has led to a greatly improved ordering of the potato reference genome superscaffolds into chromosomal pseudomolecules.

    HokieX
    Chen, Guankai; Guo, Xiao; Wang, Muyang; Chen, Youwei; Chen, Kaiyi; Asher, Tim (2023-12)
    HokieX is an online thrift shop designed specifically for Virginia Tech students, faculty, and the surrounding community. It is novel compared to other similar platforms like Facebook Marketplace as it includes verification for VT affiliates, including students and faculty. With this feature, our application will have reduced numbers of scammers and scalpers compared to competitors. However, this feature does not exclude people who are not affiliated with VT: Blacksburg residents and others in the surrounding community can also sign up and use the application. Its local focus also lends itself to Blacksburg and VT as there is a strong sense of community in this area. This means that, although those with malicious intentions could still gain access to the system, the community will reject them using the report system and keep the platform safe organically.
