Phylogenetic Classification of Seed Plants of Taiwan

Abstract

BackgroundBiological classification, the hierarchical arrangement of scientific names of organisms, constitutes the core infrastructure of biological databases. For an efficient management of biological databases, adopting a stable and universal biological classification system is crucial. Currently in Taiwan Biodiversity Information Facility (TaiBIF; http://taibif.tw/), the national portal website that integrates Taiwan’s biodiversity information databases, angiosperms are arranged according to Cronquist’s System of Classification, which is not compatible with current trend of the Angiosperm Phylogeny Group (APG) classification. To consolidate the function and management of the database, TaiBIF is moving to adopt the APG IV classification and Christenhusz et al. (Phytotaxa 19:55–70, 2011)’s classification of gymnosperms, which we summarize as the Phylogenetic Classification of Seed Plants of Taiwan.ResultsThe Phylogenetic Classification of Seed Plants of Taiwan places gymnosperms in five families [vs. eight families in the Flora of Taiwan (FOT)] and angiosperms in 210 families (vs. 193 families in FOT). Three FOT gymnosperm families are synonymized in current treatment. Of the 210 APG IV families, familial circumscriptions of 114 families are identical with FOT and 50 families are recircumscription of FOT, with 46 families newly added. Of the 29 FOT families not included in current classification, two families are excluded and 27 families are synonymized.ConclusionsThe adoption of the Phylogenetic Classification of Seed Plants of Taiwan in TaiBIF will provide better service and efficient management of the nation’s biodiversity information databases.Electronic supplementary materialThe online version of this article (10.1186/s40529-017-0206-6) contains supplementary material, which is available to authorized users.

Extensive sampling of Saccharomyces cerevisiae in Taiwan reveals ecology and evolution of predomesticated lineages

“…Among the 13 climate-related forests types in Taiwan, five are Fagaceae-dominated natural forests on low-and mid-elevation mountains (Li et al 2013), thus a potentially ideal natural habitat for S. cerevisiae. Taiwan also harbors a high phylogenetic diversity of flowering plants (53 out of 64 angiosperm orders present under the APG IV classification system) (Lin and Chung 2017) and endemism compared with other oceanic islands (Hsieh 2002), raising the possibility that the associated microbial populations are genetically different from their continental counterparts. Here, we set out to characterize the intra-genetic diversity, relative abundance, and distribution of S. cerevisiae in Taiwanese forests over 4 yr of broad sampling.…”

Precision Agriculture Through Deep Learning: Tomato Plant Multiple Diseases Recognition With CNN and Improved YOLOv7

“…The primary growing regions for tomatoes in Taiwan are located in the counties of Chiayi, Kaohsiung, Tainan, Yunlin, and Nantou, covering a total area of more than 5,000 acres of land. The average value of tomatoes produced is close to TWD 30 billion, and it continues to rise [4].…”

Deep sampling of ancestral genetic diversity reveals Saccharomyces cerevisiae pre-domestication life histories

“…Specifically, among the 13 climate-related forests types in Taiwan, five are Fagaceae-dominated natural forests on low- and mid-elevation mountains 27 , thus a potentially ideal natural habitat for S. cerevisiae. Taiwan also harbors a high phylogenetic diversity of flowering plants (53 out of 64 angiosperm orders present under the APG IV classification system 28 ) and endemism compared to other oceanic islands 29 , raising the possibility that present lineages are genetically different from their continental counterparts.…”
