The phased Solanum okadae genome and Petota pangenome analysis of 23 other potato wild relatives and hybrids.

Potato is an important crop in the genus Solanum section Petota. Potatoes are susceptible to multiple abiotic and biotic stresses and have undergone constant improvement through breeding programs worldwide. Introgression of wild relatives from section Petota with potato is used as a strategy to enhance the diversity of potato germplasm.

Pangenome analyses reveal impact of transposable elements and ploidy on the evolution of potato species.

Potato (., family Solanaceae) is the most important noncereal food crop globally. It has over 100 wild relatives in the section , which features species with both sexual and asexual reproduction and varying ploidy levels.

Plastaumatic: Automating plastome assembly and annotation.

Plastome sequence data is most often extracted from plant whole genome sequencing data and need to be assembled and annotated separately from the nuclear genome sequence. In projects comprising multiple genomes, it is labour intense to individually process the plastomes as it requires many steps and software. This study developed - an automated pipeline for both assembly and annotation of plastomes, with the scope of the researcher being able to load whole genome sequence data with minimal manual input, and therefore a faster runtime.

Genome sequencing of adapted diploid potato clones.

Cultivated potato is a vegetatively propagated crop, and most varieties are autotetraploid with high levels of heterozygosity. Reducing the ploidy and breeding potato at the diploid level can increase efficiency for genetic improvement including greater ease of introgression of diploid wild relatives and more efficient use of genomics and markers in selection. More recently, selfing of diploids for generation of inbred lines for F1 hybrid breeding has had a lot of attention in potato.

The plastome of Arctic (Fabaceae) is significantly different from that of and other related species.

Anatomical and physiological specializations for plant adaptation to harsh climates result from molecular mechanisms that can be encoded in the nucleus or organelle. In this study, the complete plastomes of an arctic species, Bunge (Fabaceae), and a closely related temperate species, Douglas ex Hook., were assembled, annotated, and analyzed to identify differences that might help explain their adaptation to different environments.
