The Gas-Sensing Properties of Ag-/Au-Modified TiCT (T=O, F, OH) Monolayers for HCHO and CH Gases.

Based on density functional theory calculations, this study analyzed the gas-sensing performance of TiCT (T=O, F, OH) monolayers modified with precious metal atoms (Ag and Au) for HCHO and CH gas molecules. Firstly, stable structures of Ag- and Au-single-atom doped TiCT (T=O, F, OH) surfaces were constructed and then HCHO and CH gas molecules were set to approach the modified structures at different initial positions. The most stable adsorption structure was selected for further analysis of the adsorption energy, adsorption distance, charge transfer, charge deformation density, total density of states, and partial density of states.

Transcriptome and Metabolome Profiling to Explore the Causes of Purple Leaves Formation in Non-Heading Chinese Cabbage ( L. ssp. Makino var. Hort.).

Purple non-heading Chinese cabbage is one of the most popular vegetables, and is rich in various health-beneficial anthocyanins. Research related to genes associated with anthocyanin biosynthesis in non-heading Chinese cabbage is important. This study performed integrative transcriptome and metabolome analysis in the purple non-heading Chinese cabbage wild type (WT) and its green mutant to elucidate the formation of purple leaves.

Latent Infection of Valsa mali in the Seeds, Seedlings and Twigs of Crabapple and Apple Trees is a Potential Inoculum Source of Valsa Canker.

A real-time quantitative PCR assay using a species-specific primer pair was developed to rapidly and accurately quantify Valsa mali, the causative pathogen of apple Valsa canker (AVC), in crabapple seeds, crabapple seedlings, apple twigs and apple seeds. Surveys were conducted in different regions, and crabapple or apple seeds were collected for V. mali detection by qPCR assay.
