    Highly Improved Electrooxidation of Captopril on Copper Hexacyanoferrate/Ordered Mesoporous Carbon-Modified Glassy Carbon Electrode
    (CSIRO Publishing, 2014) Shengjun Lu; Lu Pan; Li Cheng; Caihong Wang; Jie Yu
    Using an electrochemical polymerization process, a copper hexacyanoferrate/ordered mesoporous carbon-modified glassy carbon electrode (CuHCF/OMC/GCE) was prepared. The performance of CuHCF/OMC was compared with that of CuHCF and the properties of the new material were improved. A sensor for sensitive detection of captopril was developed based on CuHCF/OMC-modified glassy carbon electrode. The composition and morphology of the as-prepared CuHCF/OMC products were characterized by energy-dispersive X-ray spectroscopy and scanning electron microscopy. The electrochemical behaviour and electrocatalytic performance of the CuHCF/OMC-modified glassy carbon electrode towards the oxidation of captopril were evaluated by cyclic voltammetry. Results showed that the CuHCF/OMC-modified electrode exhibits two well-defined redox peaks. The linear range for the detection of captopril was from 1.0 × 10–5 to 2.7 × 10–3 M, with a correlation coefficient of 0.999, and the detection limit was 1.2 × 10–6 M based on a signal-to-noise ratio of 3.

    Identification and expression characterisation of SbERECTA family genes in Sorghum bicolor
    (CSIRO Publishing, 2021) Jiacheng Zheng; Jie Yu; Ting Liu; Xin Wang; Qiu Wen Zhan; Jie Qin Li; Xu Zhao; You Zhi
    ERECTAs are receptor-like kinases that regulate plant biomass and stress resistance. In this study, the wheat (Triticum aestivum) TaERECTA gene was used as a probe to identify the SbERECTA family genes (SbERs) in the sorghum (Sorghum bicolor) genome, analyse their subcellular localisation and characterise their expression. Results showed that the two SbER members, SbER10 with three copies (SbER10_X1, SbER10_X2, and SbER10_X3) and SbER4 with two copies (SbER4_X1 and SbER4_X2), were found on chromosomes 10 and 4 of sorghum, respectively. SbER10 had the highest expression level in the pedicel tissue and showed a remarkable response under treatment with abscisic acid, brassinolide, gibberellin and indole-3-acetic acid. SbER10_X1, functioning on the cell membrane and chloroplast, exhibited abundant transcript in only a few sorghum varieties that are grown in mountainous areas and receive strong light, heat, and water supply. Expression of SbER10_X1 was significantly and positively correlated with plant biomass of 32 sorghum germplasm resources. These results indicate that SbER10 genes have an important regulatory role in sorghum growth, and increasing SbER10 transcription level offers a potential strategic target for breeding or biotechnological approaches to enhance sorghum biomass and environmental adaptability.
