Premise of the StudyMicrosatellite markers were developed in Torreya yunnanensis (Taxaceae) to investigate the genetic diversity, phylogeography, and population structure of the species.Methods and ResultsSixteen primer sets were identified using Illumina 2 × 100‐bp paired‐end sequencing and bioinformatic screening. Most primers also amplified in T. fargesii, T. grandis, T. jackii, and T. nucifera.ConclusionsThese results indicate the utility of these microsatellite markers in T. yunnanensis for future studies of molecular ecology as well as their applicability across the genus.

This paper analyzes and sums up the current research situation of downsizing land utilization of maps, and then put forward an improved method on the basis of ArcGIS. This method is fully combined with theories and practice of map downsizing and aims at improving the efficiency and quality when downsizing land utilization maps.
