Liquid-phase epitaxial grown UiO-66 as a bifunctional platform for electrochemical Aptasensing of cardiac troponin I.

The construction of multifunctional nanointerface bearing rich active site for aptamer immobilization and effective signal transformation is critical for the development of high-performance electrochemical aptasensor. Herein, a layer of p-mercaptobenzoic acid (p-MBA) was self-assembled on the surface of bare gold electrode (AuE), acting as a scalfod for the consequent liquid-phase epitaxial growth of Universitetet i Oslo-66 (UiO-66) metal-organic framework via immersion in zirconium ions (Zr) and p-terephthalic acid (PTA) ligand. Then, the UiO-66 was utilized as a bifunctional platform for immobilization of aptamer probe for cardiac troponin I (cTnI) and the electrochemical signal transformation as an electrocatalyst.

Genome-wide identification and gene expression pattern analysis of the carotenoid cleavage oxygenase gene family in Fagopyrum tataricum.

Background: Carotenoid cleavage oxygenases (CCOs) convert carotenoids into volatile aromatic compounds implicated in plant growth and development. They affect the synthesis of hormones, including abscisic acid (ABA) and strigolactone (SL). However, the CCO family in Tartary buckwheat remains unelucidated.

Genome-wide identification and gene expression pattern analysis of the glycoside hydrolase family 1 in Fagopyrum tataricum.

Background: The β-glucosidases (BGLU) of glycoside hydrolase family 1 hydrolyze the glycosidic bond to release β-D-glucose and related ligands, which are widely involved in important physiological processes in plants. Genome-wide analysis of the BGLU genes in the model crops Arabidopsis thaliana and Oryza sativa revealed that they are functionally diverse. In contrast, the BGLU gene family in Tartary buckwheat remains unclear.

sp. nov., isolated from black comb honey.

A strain of the bacterial genus , IMAU50987, that was isolated from black comb honey from Lianghe County, Dehong Autonomous Prefecture, Yunnan Province, China, could not be accurately identified as a known species using 16S rRNA gene sequencing. In this study, the taxonomic status of strain IMAU50987 was evaluated using whole-genome sequencing combined with phenotypic analyses. Strain IMAU50987 was Gram-positive, non-motile and non-spore-forming.

Copper(II)-Tannic Acid@Cu with In Situ Grown Gold Nanoparticles as a Bifunctional Matrix for Facile Construction of Label-Free and Ultrasensitive Electrochemical cTnI Immunosensor.

Sensitive detection of cardiac troponin I (cTnI) is of great significance in the diagnosis of a fatal acute myocardial infarction. A redox-active nanocomposite of copper(II)-tannic acid@Cu (CuTA@Cu) was herein prepared on the surface of a glassy carbon electrode by electrochemical deposition of metallic copper combined with a metal stripping strategy. Then, HAuCl was in situ reduced to gold nanoparticles (AuNPs) by strong reductive catechol groups in the TA ligand.

Genome-wide identification, abiotic stress, and expression analysis of PYL family in Tartary buckwheat (Fagopyrum tataricum (L.) Gaertn.) during grain development.

Background: Abscisic acid (ABA) is a plant hormone that plays an important role in plant resistance to drought, salinity, cold, and pathogens. It is also important for regulating plant growth and development. Pyrabactin resistance/pyr1-like/regulatory components of the ABA receptor (PYL/RCAR) are ABA receptor proteins in plants and the core of ABA signal transduction pathways in plant regulatory factors.
