The HAP clade, mainly including Helichrysum Mill, Anaphalis DC., and Pseudognaphalium Kirp., is a major component of tribe Gnaphalieae (Asteraceae). In this represents the largest genus Asian Gnaphalieae. intergeneric relationships among its related genera infrageneric taxonomy are complex remain controversial. However, there few studies that have focused on these issues. Herein, based current most comprehensive sampling especially , we conducted phylogenetic analyses using chloroplast (cp) genome nuclear ribosomal DNA (nrDNA) to evaluate within test monophyly examine genus. Meanwhile, morphological characters were verified determine circumscription system . Additionally, biogeographical history, diversification processes, evolution crucial estimated inferred. Our suggested polyphyletic because it nested with Two four main clades identified in cp nrDNA trees, respectively. Compared trees more effective for resolution. After comprehensively analyzing evidence, was concluded achene surface ornamentation leaf base showed less homoplasy supported two lineages inferred from genome. indicated clade underwent rapid late Miocene Pliocene. appeared originated Africa, then spread Western Southern Asia, subsequently moved into Southwestern China forming diversity center. dispersal patterns different. One dispersed around world, except Africa South America. other one Eastern Southeastern Asia ancestral origin region.

Assembly and comparative analysis of the complete mitochondrial genome of Vaccinium carlesii Dunn

Genomics, Journal Year: 2024, Volume and Issue: 116(5), P. 110897 - 110897

Published: July 18, 2024

Vaccinium L. is an important fruit tree with nutritional, medicinal, and ornamental values. However, the mitochondrial (mt) genome of remains largely unexplored. carlesii Dunn endemic wild resource in China, which crucial for blueberry breeding. The V. mt genomes were sequenced using Illumina Nanopore, total length was 636,904 bp 37 protein coding genes, 20 tRNA three rRNA genes. We found four pairs long repeat fragments homologous recombination mediated generation substructures genome. predicted 383 RNA editing sites, all converting cytosine (C) to uracil (U). According phylogenetic analysis, macrocarpon Ericaceae exhibited closest genetic relationship. This study provides a theoretical basis understanding evolution higher plants, species classification identification, will also be useful further utilization germplasm resources.
