Abstract Taxus cuspidata is a rare plant with important medicinal and ornamental value. Aiming at the obvious differences between wild and cultivated populations of T. cuspidata from Northeast China, a total of 61 samples, that is, 33 wild yews and 28 cultivated yews were used to analyze the differences and correlations of the kinship, genetic diversity, and genetic structure between them by specific length amplified fragment sequencing (SLAF-seq). Finally, 470725 polymorphic SLAF tags and 58622 valid SNP markers were obtained. Phylogenetic analysis showed that 61 samples were classified into 2 clusters: wild populations and cultivated populations, and some wild yews were… More >

Abstract Baccharis crispa Spreng., "Carqueja", is found among the medicinal plants of Argentina, registered in the pharmacopoeia, the species. It is a rhizomatous dioic subshrub, with branches provided with three wings, 2 to 6 mm wide. According to the Conservation Priority Index (developed for the Paravachasca Valley of the Province of Córdoba), the carqueja is third in order of importance as a priority for conservation. In general, conservation includes the preservation and sustainable use of genetic resources, protecting their variability, which is essential for their maintenance. The aim of this study was to determine the existence of variability, from morphological, chemical,… More >
