The complete chloroplast genome of Rhodobryum laxelimbatum (Hampe ex Ochi) Z. Iwatsuki and T. J. Koponen

Abstract

Rhodobryum laxelimbatum (Bryophyta, Bryaceae) is one of the folk medicine resources in Southwest China, which has excellent potential for application in treating cardiovascular diseases. In this study, R. laxelimbatum was sequenced by high-throughput sequencing technology. The complete chloroplast genome is 124,632 bp in length with a quadripartite structure. Two inverted repeat regions are 9837 bp, separated by a large single copy region of 86,444 bp and a small single copy region of 18,514 bp. It encodes 118 unique genes, including 82 protein-coding genes, 32 tRNA genes, and four rRNA genes. The phylogenetic tree was constructed based on the complete chloroplast genome sequences of 18 bryophytes, downloaded from GenBank and acquired in this study. The phylogenetic analysis strongly indicated that R. laxelimbatum was the sister group of the clade which consists of Mnium marginatum , Pohlia cruda and Pohlia nutans . The R. laxelimbatum chloroplast genome sequence provides new genomic resources, which will improve its research, conservation, and application in the future.

Effect of alkali/alkaline-earth-metal doping on the Co3O4 spinel structure and N2O decomposition

“…The N 2 O decomposition performance was evaluated for different alkali/alkaline-earth-metal doped catalysts (M-Co 3 O 4 ), as well as The oxygen vacancy can be considered as another active site for N 2 O decomposition, [65][66][67][68] as illustrated in Fig. 9B.…”

Architecture Prediction of 3D Composites Using Machine Learning and No‐Destructive Technique

“…In nondestructive testing, elastic waves are used to detect flaws or defects in materials or structures. [ 21–30 ] However, in the case of the composites, the signals generated by elastic waves might be challenging to understand due to the complexity of wave propagation in composite materials and many factors that can influence it. [ 31,32 ] To analyze the information contained in output signals, ML models are the best choice since they are powerful in finding complex and nonlinear connections between output signals and the architecture of composites.…”
