Unveiling the Molecular Mechanisms of Browning in Callus through Transcriptomic and Metabolomic Analysis.

is one of the camellia plants distributed in tropical regions, and its regeneration system and genetic transformation are affected by callus browning. However, the underlying mechanism of callus browning formation remains largely unknown. To investigate the metabolic basis and molecular mechanism of the callus browning of , histological staining, high-throughput metabolomics, and transcriptomic assays were performed on calli with different browning degrees (T1, T2, and T3).

An Ultrafast and Room-Temperature Strategy for Kilogram-Scale Synthesis of Sub-5 nm Eu -doped CaMO Nanocrystals with a Photoluminescence Quantum Yield Exceeding 85.

Rare earth-doped metal oxide nanocrystals have a high potential in display, lighting, and bio-imaging, owing to their excellent emission efficiency, superior chemical, and thermal stability. However, the photoluminescence quantum yields (PLQYs) of rare earth-doped metal oxide nanocrystals have been reported to be much lower than those of the corresponding bulk phosphors, group II-VI, and halide-based perovskite quantum dots because of their poor crystallinity and high-concentration surface defects. Here, an ultrafast and room-temperature strategy for the kilogram-scale synthesis of sub-5 nm Eu -doped CaMoO nanocrystals is presented, and this reaction can be finished in 1 min under ambient conditions.

Room-temperature and ultrafast Eu ion doping for highly luminescent and extremely small CaMoO nanocrystals.

We developed a room-temperature and ultrafast Eu-ion doping approach for the synthesis of highly luminescent Eu-doped CaMoO nanoparticles. Firstly, CaMoO nanoparticles with a particle size of 3.9 nm are rapidly prepared using a room temperature co-precipitation approach.

Room-Temperature, Ultrafast, and Aqueous-Phase Synthesis of Ultrasmall LaPO:Ce, Tb Nanoparticles with a Photoluminescence Quantum Yield of 74.

LaPO:Ce, Tb nanoparticles with a particle size of 2.7 nm are prepared by a facile room-temperature ligand-assisted coprecipitation method in an aqueous solution. Short-chain butyric acid and butylamine are used as binary ligands and play a critically important role in the synthesis of highly luminescent LaPO:Ce, Tb nanoparticles.

Characterization of a splice variant of soybean ERECTA devoid of an intracellular kinase domain in response to shade stress.

The receptor-like kinase ERECTA (ER) plays vital roles in plant adaptation under environmental stress including shade avoidance in . In our previous study, we identified four ER paralogues in soybean (GmERs) that showed high similarities to ER. Each was predicted to generate diverse alternative splicing variants.

Auxin and Gibberellins Are Required for the Receptor-Like Kinase ERECTA Regulated Hypocotyl Elongation in Shade Avoidance in Arabidopsis.

Plants use shade avoidance strategy to escape the canopy shade when grown under natural conditions. Previous studies showed that the Arabidopsis receptor-like kinase ERECTA (ER) is involved in shade avoidance syndrome. However, the mechanisms of ER in modulating SAR by promoting hypocotyl elongation are unknown yet.
