A new species of Gastrodia (Orchidaceae: Epidendroideae, Gastrodieae), G. qingyunshanensis, is described and illustrated from Guangdong, China. It closely related to appendiculata C. S. Leou & N. J. Chung but can be distinguished by an urceolate (vs bell-like) dark brown pale greenish brown) perianth tube, the smaller petals (2.5 × 1.6 mm vs 4–5 5–6 mm), shape lip (oblong, 3×1.6mm ovate, 6–7×5mm), lack elevated calli at base petal having calli), appendage shorter than column equal...
A new species of Vanda, V. malipoensis, from Yunnan, China, is described and illustrated in this study based on morphological molecular evidence. Detailed comparisons between the newly discovered orchid other members Vanda s.l. indicate that malipoensis similar to christensoniana nana. The plant differs former by presence inflorescences with sparse smaller flowers, a shorter column caudiculate pollinia, it latter longer fully open flowers erect sidelobes lip. Molecular phylogenetic analyses...
The subtribe Aeridinae, which contains approximately 90 genera, is one of the most diverse and taxonomically puzzling groups in Orchidaceae. In present study, phylogenetic relationships Aeridinae were reconstructed utilizing five DNA sequences (ITS, atpI-H, matK, psbA-trnH, trnL-F) from 211 taxa 74 genera. results analyses indicate that monophyletic can primarily be grouped into 10 clades: (1) Saccolabium clade, (2) Chiloschista (3) Phalaenopsis (4) Thrixspermum (5) Vanda (6) Aerides (7)...
Loropetalum subcordatum is an endangered species endemic to China that characterized by narrow distribution, small population size, and delayed fertilization. However, the genetic diversity of entire extant natural ex situ populations has not been assessed date. In this study, we evaluated structure six a single (the only known L. subcordatum) using sequence-related amplified polymorphism data. total, 553 reliable DNA bands, which 359 (63.28%) were polymorphic, polymerase chain reaction with...
Pseudocerastium is a monotypic genus in Caryophyllaceae endemic to China. The has been widely accepted since it was described 1998, however its phylogenetic position within never studied. In the present study, whole plastid genome and nuclear ribosomal internal transcribed spacer (ITS) sequences of stellarioides obtained through skimming, species studied for first time. Plastid phylogenomic analysis revealed that clustered tribe Alsineae with strong support. Phylogenetic analyses based on an...
Alsineae are one of the most taxonomically difficult tribes in Caryophyllaceae and consist over 500 species distributed northern temperate zone. Recent phylogenetic results have improved our understanding on evolutionary relationships among members. Nevertheless, there still some unresolved taxonomic problems at generic level, history major clades within tribe was unexplored to date. In this study, we carried out analyses divergence time estimation using nuclear ribosomal internal...
Bulbophyllum lipingtaoi, a new orchid species from Yunnan, China, is described and illustrated. Detailed comparative morphological analyses indicate that this distinct other of in having single-flowered inflorescence with scape arising the node rhizome, entire margins sepals petals, lateral twisted near base. Furthermore, molecular phylogenetic based on nuclear ribosomal ITS plastid DNA (matK atpI-atpH) support placement B. lipingtaoi as member section Brachyantha. Section Brachyantha...
Camellia oleifera is a major woody oilseed species in China, but it typically cultivated nutrient-poor soils and may be affected by various trace elements. This study examined how spraying selenium, boron, zinc elements the traits functional active compounds of C. under nutrient deficiency. The results revealed significant variations effects different element combinations on oleifera. Optimal concentrations selenium are critical for promoting growth development fruit. transverse diameter...
Dendrobium catenatum (Dendrobium officinale) is a valuable genuine herb. The source of this species difficult to be identified by traditional methods including morphology, spectroscopy, and chromatography. We used the restriction site-associated DNA sequencing (RAD-seq) approach perform high-throughput 24 D. provenances. In study, 371.18 Gb clean data were obtained, 655,057 high-quality SNPs selected after their filtration. phylogenetic tree, genetic structure, principal component analyses...
Glochidion liangkwangense, a new species from Guangdong and Guangxi Provinces, China, belonging to subgenus Pseudoactephila, is here described. The grows in limestone hills. It most similar anthopotamicum morphology, but it could be easily distinguished the later by its sepals that are erect usually extend outward (vs. spreaded or even reflexed at upper part, jointly formed urceolate shape lower part), of female flowers 2 series different size subequal both size), disc segments short...
Psammosilene tunicoides is an endangered medical herb endemic to south-western China. In this study, the complete plastid genome of species was characterized and assembled using next-generation DNA sequencing method. The 153,978 bp in length, including a large single copy (LSC) region 83,981 small (SSC) 17,489 bp, which were separated by pair inverted repeat (IR) regions 26,254 bp. encoded 112 unique genes, 78 protein-coding four ribosomal RNA 30 transfer genes. overall GC content whole...
Hoya is a remarkable genus with high horticultural ornamental value. In this study, we report and characterize the complete plastid genome sequence of carnosa. The chloroplast was 176,340 bp in length, which includes pair inverted repeat regions (IRs) 41,381 separated by large single copy region (LSC) 91,281 small (SSC) 2,297 bp. Interestingly, IRs expanded into SSC, result that most genes SSC were duplicated. This contained 110 genes, including 76 protein-coding 30 tRNA 4 rRNA genes....
A new species of Begonia section Coelocentrum, B. guangdongensis W.H. Tu, B.M. Wang & Y.L. Li from Guangdong Province, China, is described and illustrated here. Morphologically, the most similar to biflora T. C. Ku longistyla Y. M. Shui W. H. Chen, but differs by its rugose leaves glabrous capsules stipules without ciliate margin, densely hirsute-pilose obtuse apex bracts. Additionally, it also somewhat chongzuoensis Yan Liu, S. C.-I Peng, there are significant distinctions in their...
The species Anisomeles indica is used medicinally and widely distributed from India, to China the Indo-China Peninsula. first complete plastid genome sequence of A. reported here was 151,900 bp long, with large single copy (LSC) region 83,144 bp, small (SSC) 17,556 two inverted repeats (IRa IRb) 25,600 bp. plastome contained 113 genes, including 79 protein-coding 4 ribosomla RNA genes 30 transfer genes. overall GC content 38.26%.
