RESUMO

Acalypha australis L. 1753 is a potherb popular among Asian populations and is a traditional herbal medicine. In the current study, the overall genetic diversity of A. australis still needs to be better. Here, we assembled and characterized the complete plastome of A. australis. The plastome is 168,885 bp in length with a large single-copy (LSC) of 94,576 bp, a small single-copy (SSC) of 19,715 bp, and two copies of inverted repeat region (IRs) of 27,297 bp each. The overall GC content is 34.9%. The plastome contains 127 genes, including 83 protein-coding genes, 36 tRNA genes, and eight rRNA genes. Phylogenomic analysis of the representative species of Euphorbiaceae showed that A. australis and A. hispida formed a monophyletic sister clade. The results of this study will support further research on the evolution and conservation of the Euphorbiaceae species; they will benefit pharmaceutical applications and ornamentation of the medicinal plant A. australis.

RESUMO

Campsis radicans (L.) Bureau 1864, a species of Bignoniaceae, has a widespread paleotropical distribution and is utilized for horticultural and traditional Chinese medicinal purposes. Despite the plant's significance, its genetic diversity must be better understood. In this study, we have successfully assembled and characterized the complete plastome of C. radicans, marking a significant advancement toward comprehending its genetic composition. The plastome is 153,630 bp long and harbors 130 genes, including 86 protein-coding genes, 36 tRNA genes, and eight rRNA genes. Our phylogenomic analysis of the representative species of Bignoniaceae indicated that C. radicans formed a monophyletic sister clade of Campsis with C. grandiflora. These findings are crucial for conserving and utilizing this important plant species. They also highlight the potential for future research into the evolution and preservation of C. radicans, which could be advantageous in pharmaceutical applications.

RESUMO

Light-driven actuators that directly convert light into mechanical work have attracted significant attention due to their wireless advantage and ability to be easily controlled. However, a fundamental impediment to their application is that the continuous motion of light-driven flexible actuators usually requires a periodically switching light source or the coordination of other additional hardware. Here, for the first time, continuous flapping-wing motion under sunlight is realized through the utilization of a simple nanocrystalline metal polymer bilayer structure without the coordination of additional hardware. The light-driven performance can be controlled by adjusting the grain size of the upper nanocrystalline metallic layer or selecting metals with different thermodynamic parameters. The achieved highest frequency of flapping-wing motion is 4.49 Hz, which exceeds the frequency of real butterfly wings, thus informing the further development of sunlight-driven bionic flying animal robotics without external energy consumption. The flapping-wing motion has been used to realize a light-driven whirligig, a light-driven sailboat, and photoelectric energy harvesting. Furthermore, the flexible bilayer actuator features the ability to be driven by light and electricity, low-power actuation, a large deflection, fast actuation speed, long-time stability, strong design ability, and large-area facile fabrication. The bilayer film considered herein represents a simple, general, and effective strategy for preparing photoelectric-driven flexible actuators with target performances and informs the standardization and industrial application of flexible actuators in the future.
