Recently, photo-assisted electrocatalysis as an emerging catalytic approach that combines the technologies of photocatalysis and electrocatalysis has attracted great interest among researchers. Under this circumstance, the NiFe-LDH compounded with PbS based (PbS@NFHS) heterojunction with both photoactive and electrocatalytic properties was constructed for the first time through an ambient etching route and a subsequent low-temperature hydrothermal method. The as-prepared catalyst displayed a novel hierarchical 3D open structure based on nanosheets, which offered numerous electrochemically active sites, facilitated the swift diffusion of ions and enhanced both electrical conductivity and catalytic stability, thus significantly improving the catalytic performance. Furthermore, the charge redistribution in the p–n junction led to the formation of space-charge regions and a built-in electric field, which benefited the charge transfer and thereby enhanced the intrinsic activity. Under illumination, electrochemical tests showed that the overpotential was only 291 mV for the OER at 50 mA cm−2 in 1 M KOH solution, which was 50 mV lower than that without illumination. Moreover, the catalyst can maintain stability for 40 hours at a current of 10 mA cm−2 in 1 M KOH. Compared to the traditional electrocatalytic OER, this work employed a very promising photo-assisted electrocatalytic strategy, which could further broaden the wide application of NiFe-LDH.

Amino acid/auxin permease (AAAP) is a transcription factor with a highly conserved amino acid region that regulates physiological processes and development in many plants and responds to various abiotic stresses. In this study, a genome-wide analysis of five legumes (Phaseolus vulgaris, Medicago truncatula, Lotus japonicus, Glycine max, and Cicer arietinum) identified 74, 106, 87, 147, and 70 AAAP genes, respectively. In addition, chromosomal localisation, phylogenesis, conserved motifs, gene structure, and gene replication analyses were performed on AAAP genes. The results showed that legume AAAP gene branches from the same evolutionary system had similar protein structures. In addition, by analysing the transcriptome data, we determined that the expression levels of AAAP differed in each tissue. Quantitative real-time polymerase chain reaction (qRT-PCR) was performed to investigate the expression patterns of AAAP under tissue-specific conditions. These results show that AAAP genes play crucial regulatory roles in tissue-specific gene expression. This study provides a basis for further exploration of the biological functions of the AAAP gene family in legumes. AAAP plays an important role in the growth and development of the five legumes. In particular, tissue-specific expression analysis provides a scientific basis for the development of agricultural production of these five legumes. [ABSTRACT FROM AUTHOR]
