Elsholtzia fruticosa is an ornamental plant with high medicinal value. In this study, we sequenced and analyzed the complete chloroplast (cp) genome of the species. The complete cp sequence is 151,550 bp, including the large single-copy (LSC) region of 82,778 bp, the small single-copy (SSC) region of 17,492 bp, and a pair of invert repeats (IRs) regions of 25,640 bp. It encodes 132 unique genes in total, including 87 protein-coding genes, 37 transfer RNA genes (tRNAs), and eight ribosomal RNA genes (rRNAs). The comparative analysis of complete cp genomes showed that the genomic structure and gene order of E. fruticosa cps were conserved. The sequences of rps15 , rps19 , ycf1 , ycf3 , ycf15 , psbL , psaI , trnG-UCC , trnS-GCU , trnR-UCU , trnL-UAG , trnP-UG , and trnL-UAA serve as hotspots for developing the DNA barcoding of Elsholtzia species. There are 49 SSR loci in the cp genome of E. fruticosa , among which the repeat numbers of mononucleotide, dinucleotide, trinucleotide, tetranucleotide, and pentanucleotides SSR are 37, 9, 3, 0, and 0, respectively. A total of 50 repeats were detected, including 15 forward repeats, seven reverse repeats, 26 palindromic repeats, and two complementary repeats. Phylogenetic analysis based on the complete cp genome and protein-coding DNA sequences of 26 plants indicates that E. fruticosa has a dose relationship with E. splendens and E. byeonsanensis .

“…GO enrichment analysis showed that genes related to low-temperature response, hormone response, photosystem II, chloroplasts, DNA replication, ribosomal RNA processing, and translation were signi cantly enriched in different exogenous substance treatments under low-temperature conditions. Photosystem II and chloroplasts play a crucial role in plant photosynthesis, facilitating the chemical processes that provide energy for growth [51] . DNA replication is a crucial process that organisms undergo in preparation for cell division and proliferation.…”

Low temperature is one of the environmental factors that restrict the growth and geographical distribution of brassica. To investigate the effects of exogenous calcium and calcium inhibitors on the ability of winter rapeseed (Brassica rapa L.) to withstand low temperatures, and its effect on physiological characteristics we used a strong cold-resistant Longyou 7 (L7) and a weak cold-resistant Longyou 99 (L99) cultivar. The seedlings were treated with CaCl2 (20 mmol·L-1) and the calcium inhibitor LaCl3 (10 mmol·L-1) at 0 h, 6 h, 12 h, 24 h and 48 h, the Ca2+ flux and Ca2+ concentration in the roots after 12 h and 24 h of treatment were analyzed, and results after low-temperature treatment, L99 showed Ca2+ efflux with a rate of 30.21 pmol‧cm-2‧s-1, whereas L7 briefly showed efflux then returned to influx. Moreover. our findings illustrate that under low-temperature conditions, the activities of superoxide dismutase (SOD), peroxidase (POD), and catalase (CAT) were increased by both CK and exogenous CaCl2 treatments. The contents of soluble protein (SP) and proline (Pro) were increased, while the contents of malondialdehyde (MDA) were decreased, resulting in reduced membrane lipid peroxidation. But enzyme activity decreased and MDA content increased following treatment with exogenous LaCl3. The rate of Ca2+ flow showed a higher uptake in L7 roots compared with L99. Calcium ion content in root showed a decrease in ion content in both cultivars after CaCl2 treatment. The results of RNA-seq data revealed that the genes that are differentially expressed in response to low temperatures, hormones, photosystem II, chloroplasts, DNA replication, ribosomal RNA processing, and translation were significantly enriched. This study found significant expression of genes related to cellular signal transduction (MAPK signaling pathway) and material metabolism (nitrogen metabolism, glycerol ester metabolism). The analysis of MAPK signaling pathway and genes in two modules led to the screening of 8 candidate genes related to the regulation of root growth, development and signal transduction.

“…The leaves of Phalaenopsis species play important roles in the plant's response to changes in environmental factors, including light, humidity, and temperature [1, 2]. The large surfaces of the leaves contain various lipids, and sites at which photochemical reactions and protein synthesis occur during nutrition and blooming [3].…”

Chemical components in the hexane‐extract mixture from Phalaenopsis leaves were isolated and identified during the spike induction process. Several lipophilic components in the hexane‐extract mixture were isolated and identified as oleic acid, 1,2‐O‐dilinolenoyl‐MGDG, 1‐O‐linolenoyl‐2‐O‐linoleoyl‐MGDG, and α‐tocopherol by HPLC and NMR techniques. It is noteworthy that only one isomer of α‐tocopherol was isolated from Phalaenopsis leaves based on NMR spectra analysis. MGDG have a great potential to be a control factor in the regulation of spike process of Phalaenopsis. It is the first time to identify the chemical MGDG related to temperature‐controlled process of Phalaenopsis. These components have hydrophilic and hydrophobic moieties in the same molecule to act as potential amphiphiles. The use of the entire mixed hexane extract to form liposomes containing the dmbpyPtCl2 complex greatly enhanced the reactivity of the complex for inhibiting E. coli growth compared with the use of a single amphiphile.
