Data from: ITS all right mama: Investigating the formation of chimeric sequences in the ITS2 region by DNA metabarcoding analyses of fungal mock
- 负责人：
- DOI：
- doi:10.5061/dryad.n4cv3
- 摘要：
- The formation of chimeric sequences can create significant methodological bias in PCR-based DNA metabarcoding analyses. During mixed-template

- 摘要：
- , a phylogenetic study of the Poaceae (grass family) suggested over 70 independent origins of salt tolerance, most giving rise to only one or a few salt tolerant species

- 摘要：
- The origin and evolution of polyploids have been studied extensively in angiosperms and ferns but very rarely in gymnosperms. With the exception
