“…In this study, we sequenced the complete chloroplast genome of P. Dancong tea by using Illumina high-throughput sequencing technology. The genomes ranged from 157,041 to 157,137 bp, which is consistent with the known sizes of other Camellia species, such as C. japonica (157,001 bp, Accession number: MW602996.1) [ 34 ] and C. rostrata (156,547 bp, Accession number: MW755303.1) [ 35 ]. Its quadripartite organization consists of two copies of IRs separating LSC and SSC, which are almost identical to previously reported angiosperm chloroplast genomes [ 11 ].…”

Theaceae species are dicotyledonous angiosperms with extremely high ornamental and economic value. The chloroplast genome is traditionally used to study species evolution, expression of chloroplast genes and chloroplast transformation. Codon usage bias (CUB) analysis is beneficial for investigations of evolutionary relationships and can be used to improve gene expression efficiency in genetic transformation research. However, there are relatively few systematic studies of the CUB in the chloroplast genomes of Theaceae species. In this study, CUB and nucleotide compositions parameters were determined by the scripts written in the Perl language, CodonW 1.4.2, CU.Win2000, RStudio and SPSS 23.0. The chloroplast genome data of 40 Theaceae species were obtained to analyse the codon usage (CU) characteristics of the coding regions and the influence of the source of variation on CUB. To explore the relationship between the CUB and gene expression levels in these 40 Theaceae plastomes, the synonymous codon usage order (SCUO) and measure independent of length and composition (MILC) values were determined. Finally, phylogenetic analysis revealed the genetic evolutionary relationships among these Theaceae species. Our results showed that based on the chloroplast genomes of these 40 Theaceae species, the CUB was for codons containing A/T bases and those that ended with A/T bases. Moreover, there was great commonality in the CUB of the Theaceae species according to comparative analysis of relative synonymous codon usage (RSCU) and relative frequency of synonymous codon (RFSC): these species had 29 identical codons with bias (RSCU > 1), and there were 19 identical high-frequency codons. The CUB of Theaceae species is mainly affected by natural selection. The SCUO value of the 40 Theaceae species was 0.23 or 0.24, and the chloroplast gene expression level was moderate, according to MILC values. Additionally, we observed a positive correlation between the SCUO and MILC values, which indicated that CUB might affect gene expression. Furthermore, the phylogenetic analysis showed that the evolutionary relationships in these 40 Theaceae species were relatively conserved. A systematic study on the CUB and expression of Theaceae species provides further evidence for their evolution and phylogeny.

Inorganic photoluminescence (PL) phosphors (including upconversion (UC), down‐shifting (DS), and persistent (PersL) materials) with tunable outputs, high quantum yields (QYs), and excellent photostability have attracted tremendous attention in advanced information hiding and encoding (IHE). The three kinds of phosphors endow security patterns in different IHE levels owing to their unique optical features. For security applications, it is very necessary to review how to boost optical performance and achieve multi‐level anti‐counterfeiting. Herein, diversely pivotal approaches on the achievement of multicolor emissions, high QYs, and excellent photostability are summarized. Full learning of these methods is promising to design superior inorganic phosphors. Based on the appealing optical properties of inorganic PL materials, a progressively improved IHE level is revealed by using unitary inorganic PL material, the couples of UCL, DS, and PersL, and further combinations together with external stimuli. This review not only deepens an understanding of designing high‐performance inorganic PL phosphors, but also gets inside into the construction of high‐performance IHE.
