Ecogeography of ploidy variation in cultivated potato (Solanum sect. Petota).

UNLABELLED PREMISE OF THE STUDY The taxonomy of cultivated potatoes has been highly controversial, with estimates of species numbers ranging from 3 to 17. Ploidy level has been one of the most important taxonomic characters to recognize cultivated potato species, containing diploid (2n = 2x = 24), triploid (2n = 3x = 36), tetraploid (2n = 4x = 48), and pentaploid (2n = 5x = 60) cultivars. We...

Four Newly Recorded Amanita Species in Korea: Amanita sect. Amanita and sect. Vaginatae

We collected nearly 70 specimens of Amanita species during a diversity study of Korean mushrooms conducted in 2012. In this study, we primarily investigated 23 Amanita specimens belonging to sections Amanita and Vaginatae. Based on sequence data of the internal transcribed spacers and partial large subunit of ribosomal RNA and morphological characteristics, we identified the following 15 phylog...

Complete chloroplast genomes from apomictic Taraxacum (Asteraceae): Identity and variation between three microspecies

Chloroplast DNA sequences show substantial variation between higher plant species, and less variation within species, so are typically excellent markers to investigate evolutionary, population and genetic relationships and phylogenies. We sequenced the plastomes of Taraxacum obtusifrons Markl. (O978); T. stridulum Trávniček ined. (S3); and T. amplum Markl. (A978), three apomictic triploid (2n =...

SECT ION I Introduction: RNA viruses

Viruses that infect the central nervous system may cause acute, chronic, or latent infections. In some cases, the diseases manifested are attributable to viral damage of neurons or supporting parenchymal tissues; in other cases, to immune attack on virally infected cells. They can be spread by excretion, by respiratory droplets or fomites, or, alternatively, by bites of insects or animals. Thes...
