Potentilla L. and Dasiphora are predominantly perennial herbs, occasionally manifesting as annuals or shrubs, primarily found in the northern temperate zone. However, taxonomic classification within this group remains contentious, particularly regarding genus boundaries species delineation. Therefore, study sequenced analyzed complete plastid genomes of 19 from Dasiphora, comparing them with five previously published sequences. Our objectives included reconstructing phylogenetic...

ABSTRACT Natural hybridization is a significant driving force in plant evolution and speciation. Understanding the genetic mechanism dynamic evolutionary trajectories of divergence between species hybrids remains central goal biology. Here, we examined Peganum their intermittent hybrid entities (IHEs) from large‐scale sympatric allopatric regions. We sequenced genomes Arid Central Asia (ACA) region its surrounding areas, discovering that origin could be traced to Hexi Corridor eastern Asia,...

Abstract Background Allopatric divergence is often initiated by geological uplift and climate oscillations. Qinghai-Tibet Plateau an excellent place for such research because the plants of this area have experienced historical processes as glacial contraction, interglacial expansion geographical isolation. Here in study, we used Genotyping-By-Sequencing data to investigate allopatric Lancea tibetica , endemic herb Plateau. A total 12,005 high-quality single nucleotide polymorphisms were...

Abstract Artemisia L. is one of the most diverse genera in Asteraceae, widely used agriculture and medicine, with a giant range complicated taxa. The task establishing phylogeny difficulties owing to highly similar morphological characters. East Asia, biodiversity hotspot major usage area for Artemisia, has received limited attention. Here, we collected 71 species (two subspecies, 94 samples) its allies from Asia neighbouring regions, combined public databases, ensuring representation all...

The water lily aphid (Rhopalosiphum nymphaeae) is a highly polyphagous herbivore that causes severe damage to many terrestrial and aquatic plants, especially lotus. Due environmental concerns about pollution other issues caused by chemical control methods, there an urgent need develop effective sustainable methods. harlequin ladybird (Harmonia axyridis) well-known predator may pose potential threat R. nymphaeae. To study the predation ability of H. axyridis at different developmental stages...

Abstract Genus Comastoma (subt. Swertiinae, Gentianaceae) contains species, such as “Zangyinchen,” that are important herbs in Tibetan medicine. The phylogenetic relationship of this within Gentianaceae and the circumscriptions its species have long been controversial with conflicting morphological molecular data reported. Here, we used whole chloroplast genome sequences for related taxa to reconstruct their phylogeny clarify taxonomic relationships. results revealed length all plastome...

Ajania Poljakov, an Asteraceae family member, grows mostly in Asia's arid and semi-desert areas is a significant commercial decorative plant. Nevertheless, the genus' classification has been disputed, evolutionary connections within genus have not thoroughly defined. Hence, we sequenced analyzed Ajania's plastid genomes combined them with ETS data to assess their phylogenetic relationships.We obtained total of six new nine sequences. The whole plastome lengths species sampled ranged from...

Qinghai-Tibetan Plateau (QTP) is an important biodiversity hub, which very sensitive to climate change. Here in this study, we investigated genetic diversity and past population dynamics of Lancea tibetica (Mazaceae), endemic herb QTP adjacent highlands. We sequenced chloroplast nuclear ribosomal DNA fragments for 429 individuals, collected from 29 localities, covering their major distribution range at the QTP. A total 19 haplotypes 13 genotypes two well-differentiated lineages,...

The taxonomic status of Parnassia has been widely discussed, which placed in more than five families, Parnassiaceae, Droseraceae, Saxifragaceae, and Celastraceae. Due to the lack reliable genetic data, we sequenced analyzed P. brevistyla chloroplast genome for future study. complete genomes was with NovaSeq 6000. full length is 151,728 bp. A total 114 unique genes, including 30 tRNA four rRNA 80 protein-coding genes were found genome. Using whole sequences alignment 10 species from...

Ephedra species were erect, branching shrubs found in desert or arid regions worldwide as the source of ephedrine alkaloids. In this study, complete chloroplast genome przewalskii and E. monosperma on Qinghai-Tibet Plateau sequenced, assembled, annotated. Compared with other four published species, genomes highly conservative, a quadripartite structure. The length was 109,569 bp 36.6% GC 109,604 GC. We detected 118 genes both including 73 PCGs, 37 tRNA genes, eight rRNA genes. Among them,...

The complete chloroplast (cp) genome of Neopallasia pectinata was sequenced and analyzed in this study. It 150,766 bp length has a typical circular structure, including large single copy (LSC) with 82,605 bp, two inverted repeats (IRs) 24,944 small (SSC) 18,273 bp. phylogenetic analysis N. its related taxa conducted depended on the cp-genome sequences. maximum likelihood tree indicates close relationship between Chrysanthemum Neopallasia. is useful for future studies Asteraceae.

Here in this work, we have sequenced the complete chloroplast genome of Comastoma falcatum. The size C. falcatum is 151,423 bp with 81721 LSC, 25727 IRa/IRb and 18248 SSC. GC contents its genomes are 38.26%. Their has a total 133 unique genes, including 88 protein-coding 8 rRNA 37 tRNA genes. In maximum parsimony phylogenetic tree, clustered Swertia mussotii. This will help to further study position Comastoma.

The Palaemonetes sinensis aquaculture industry in Panjin City, Liaoning Province, China, experienced heavy losses October 2018. Morbidity of cultured shrimp reached 50% and was characterized by cloudiness muscle the gradual spread disease within population. When infection mild, histopathological examinations revealed that cells contained a considerable number microorganisms. In extreme cases, structure hepatopancreatic glandular fiber obscured or even vanished. Electron microscope...

Parnassia L., a perennial herbaceous genus in the family Celastraceae, consists of about 60 species and is mainly distributed Pan-Himalayan surrounding mountainous regions. The taxonomic position phylogenetic relationships are still controversial. Herein, we reassessed status its intra- inter-generic phylogeny within Celastraceae. To that end, sequenced assembled whole plastid genomes nuclear ribosomal DNA (nrDNA) 48 (74 individuals), including 25 23 from other genera We integrated high...
