Premise Of The Study: Microsatellite or simple sequence repeat (SSR) markers were developed to investigate the influence of ecological factors on gene flow and spatial genetic structuring of the submerged plant (Ranunculaceae), which is regarded as an important species for understanding how plants adapt to an aquatic environment.
Methods And Results: Twenty-two microsatellite loci were identified from an expressed sequence tag (EST) library. The number of alleles per locus ranged from one to five, and the expected heterozygosity varied from 0.0 to 0.5 in four Chinese populations of . Fourteen loci were polymorphic and significantly deviated from Hardy-Weinberg equilibrium. All of the loci were found to be amplifiable in two other species of section , and cross-amplification in six riparian and aquatic species of Ranunculaceae was also partially successful.
Conclusions: These novel EST-SSR markers will be useful for ecological and evolutionary studies of as well as related species.

(Fabricius) is an invasive insect pest capable of causing enormous economic losses to a broad spectrum of leguminous crops. Microsatellites are valuable molecular markers for population genetic studies; however, an inadequate number of microsatellite loci are available to carry out population association studies. Thus, we utilized this insect's public domain databases for mining expressed sequence tags (EST)-derived microsatellite markers.

Identifying genes/loci for resistance to pine wilt disease (PWD) caused by the pine wood nematode (PWN) is beneficial for improving resistance breeding in , but to date, genetic information using molecular markers has been limited. Here, we constructed a high-density linkage map using genotyping-by-sequencing (GBS) and conducted quantitative trait loci (QTL) analysis for PWD resistance for the self-pollinated progeny of "Namikata 73," which is the most resistant variety among resistant varieties of , following inoculation tests with PWN. An S mapping population consisting of the 116 progenies derived from self-pollination of the resistant variety, "Namikata 73" (resistance rank 5 to PWN), was inoculated with PWN isolate Ka-4 and evaluated for disease symptoms.

The accuracy and efficiency of marker-assisted selection (MAS) has been proven for economically critical aquaculture species. The potato grouper (), a novel cultured grouper species in Taiwan, shows large potential in aquaculture because of its fast growth rate among other groupers. Because of the lack of genetic information for the potato grouper, the first transcriptome and expressed sequence tag (EST)-derived simple sequence repeat (SSR) and single nucleotide polymorphism (SNP) markers were developed.
