The B-box transcription factor BBX5 enhances UV-B resistance by promoting anthocyanin biosynthesis in Arabidopsis.

Ultraviolet-B (UV-B) light, a natural component of sunlight, plays a crucial role in the regulation of plant growth and development. B-box (BBX) proteins are zinc-finger transcription factors essential for plant growth, development, and responses to abiotic stress. The role of BBX5 in UV-B stress responses has not been previously identified.

Symmetric Boron-Bridged Carbon Quantum Frameworks for Light-Emitting Diodes with over 20% External Quantum Efficiency.

The development of eco-friendly solution-processed quantum dots plays an important role in the fabrication of electroluminescent light-emitting diodes (LEDs) for large-area display applications. However, the efficiency of these eco-friendly devices is still significantly lower than that of heavy metal-based state-of-the-art alternatives. Herein, we demonstrate metal-free carbon-based quantum materials: symmetric boron-bridged carbon quantum frameworks (-B-CQFs) composed of four dibenzo[fg,op]tetracene blocks bonded by boron atoms to form a rigid nonplanar conjugated framework.

Machine Learning Prediction on Birefringence of Nonlinear Optical Crystals and Polymorphs with Different Birefringence Activities.

Nonlinear optical (NLO) crystal materials have been widely used in the scientific and industrial fields. Birefringence is an important property of the NLO crystals. Tuning appropriate birefringence through element substitution or polymorphic transformation may promote phase-matching performance facing various demands of laser wavelength.

DeePMD-kit v3: A Multiple-Backend Framework for Machine Learning Potentials.

In recent years, machine learning potentials (MLPs) have become indispensable tools in physics, chemistry, and materials science, driving the development of software packages for molecular dynamics (MD) simulations and related applications. These packages, typically built on specific machine learning frameworks, such as TensorFlow, PyTorch, or JAX, face integration challenges when advanced applications demand communication across different frameworks. The previous TensorFlow-based implementation of the DeePMD-kit exemplified these limitations.

Multi-fidelity machine learning for predicting bandgaps of nonlinear optical crystals.

Nonlinear optical (NLO) materials are of great importance in modern optics and industry because of their intrinsic capability of wavelength conversion. Bandgap is a key property of NLO crystals. In recent years, machine learning (ML) has become a powerful tool to predict the bandgaps of compounds before synthesis.

Effects of short-term water velocity stimulation on the biochemical and transcriptional responses of grass carp ().

Since 2011, ecological operation trials of the Three Gorges Reservoir (TGR) have been continuously conducted to improve the spawning quantity of the four major Chinese carp species below the Gezhouba Dam. In particular, exploring the effects of short-term water velocity stimulation on ovarian development in grass carp () is essential to understand the response of natural reproduction to ecological flows. We performed ovary histology analysis and biochemical assays among individuals with or without stimulation by running water.

Leaf Cuticular Transpiration Barrier Organization in Tea Tree Under Normal Growth Conditions.

The cuticle plays a major role in restricting nonstomatal water transpiration in plants. There is therefore a long-standing interest to understand the structure and function of the plant cuticle. Although many efforts have been devoted, it remains controversial to what degree the various cuticular parameters contribute to the water transpiration barrier.

Functional Divergence of Multiple Duplicated Foxl2 Homeologs and Alleles in a Recurrent Polyploid Fish.

Evolutionary fates of duplicated genes have been widely investigated in many polyploid plants and animals, but research is scarce in recurrent polyploids. In this study, we focused on foxl2, a central player in ovary, and elaborated the functional divergence in gibel carp (Carassius gibelio), a recurrent auto-allo-hexaploid fish. First, we identified three divergent foxl2 homeologs (Cgfoxl2a-B, Cgfoxl2b-A, and Cgfoxl2b-B), each of them possessing three highly conserved alleles and revealed their biased retention/loss.

Apolipoprotein L1 is transcriptionally regulated by SP1, IRF1 and IRF2 in hepatoma cells.

Apolipoprotein L1 (APOL1) participates in lipid metabolism. Here, we investigate the mechanisms regulating APOL1 gene expression in hepatoma cells. We demonstrate that the -80-nt to +31-nt region of the APOL1 promoter, which contains one SP transcription factor binding GT box and an interferon regulatory factor (IRF) binding ISRE element, maintains the maximum activity.
