福建新记录种缘生穴子蕨及其叶绿体基因组分析
A Newly Recorded Species of Prosaptia contigua in Fujian Province and Analysis of Its Chloroplast Genome
摘要
Abstract
A newly recorded genus of ferns,Prosaptia C.Presl,and a newly recorded species,Prosaptia contigua(G.Forst.)C.Presl,were identified in Fujian Province.The corresponding habitat and detailed images were provided,and the voucher specimens were preserved in the Herbarium of Fujian Normal University(FNU).In addition to morphological identification,a phylogenetic tree was constructed based on the combined genes of rbcL and atpB.The results showed that the newly recorded species matched the P.contigua in the NCBI database(BP/PP=93/0.99),providing strong support.The chloroplast genome genome was sequenced,assembled,and annotated using the second-generation high-throughput whole genomes sequencing,revealing a typical four-stage structure with a total length of 148 722 bp and comprising 123 genes(including 31 tRNA genes,8 rRNA genes and 84 protein-coding genes).These findings provide a solid foundation for subsequent studies on the phylogeny of Polypodiaceae.关键词
