Single-atom catalysts (SACs) have been increasingly acknowledged for their performance in sustainable Fenton-like catalysis. However, SACs face a trade-off between activity and stability in peroxymonosulfate (PMS)-based systems. Herein, we design a nano-island encapsulated single cobalt atom (Co-ZnO) catalyst to enhance the activity and stability of PMS activation for contaminant degradation via an "island-sea" synergistic effect.

The Arabidopsis (Arabidopsis thaliana) transcription factor ABA INSENSITIVE 5 (ABI5) is a central regulator of ABA signaling. ABI5 BINDING PROTEIN 1 (AFP1) interacts with ABI5 and facilitates its 26S-proteasome-mediated degradation, although the detailed mechanism has remained unclear.

- Canavalia rosea, commonly known as bay bean, is a halophyte found in coastal tropical and subtropical regions, known for its ability to tolerate seawater and drought, potentially due to aquaporins (AQPs), which are proteins that help regulate water transport in plants.
- Researchers identified 37 different aquaporins in the C. rosea genome, categorized into five subgroups, and found that these AQPs exhibit organ-specific expression, suggesting some are crucial for the plant’s adaptation to extreme environments, like coral reefs.
- The study highlighted the significant role AQPs play in C. rosea's response to saline and drought conditions, enhancing our understanding of AQP functions and plant adaptation evolution.
Article Synopsis
- * The study focuses on a PIP2 gene cloned from a halophyte plant, examining its role in helping plants tolerate extreme salt-alkali and drought conditions, particularly under stress from high salinity and osmotic pressure.
- * Overexpression of this PIP2 gene in plants improved their survival and growth in drought conditions and increased tolerance to salt and alkaline environments, mainly by regulating water balance rather than enhancing the plant's ability to handle reactive oxygen species (ROS).
Background: Early prediction of response to neoadjuvant chemotherapy (NAC) is critical in choosing appropriate chemotherapeutic regimen for patients with locally advanced breast cancer. Herein, we sought to identify potential biomarkers to predict the response to neoadjuvant chemotherapy for breast cancer patients.
Methods: Three genomic profiles acquired by microarray analysis from subjects with or without residual tumors after NAC downloaded from the GEO database were used to screen the differentially expressed genes (DEGs).
Article Synopsis
- Phytochelatin synthases (PCSs) are essential for plant heavy metal tolerance by producing phytochelatins that bind heavy metals, decreasing cell damage; they are important for phytoremediation efforts.
- A specific PCS gene, IpPCS1, was identified in the plant Ipomoea pes-caprae, and its role in cadmium (Cd) tolerance was examined, showing that a shortened version of this gene can improve Cd tolerance in yeast and induce Cd accumulation.
- Results indicate that while IpPCS1 can enhance Cd tolerance and might be beneficial for genetic engineering to improve plant phytoremediation, a new potential Cd activation site was also discovered in the gene's C-terminal region.
Late embryogenesis abundant (LEA) proteins belong to a large family that exists widely in plants and is mainly involved in desiccation processes during plant development or in the response to abiotic stresses. Here, we reported on an atypical LEA gene (IpLEA) related to salt tolerance from Ipomoea pes-caprae L. (Convolvulaceae).

Here, we performed Full-length cDNA Over-eXpressor (FOX) gene hunting with a functional screening of a cDNA library using a salt-sensitive yeast mutant strain to isolate the salt-stress-related genes of ( genes). The library was screened for genes that complemented the salt defect of yeast mutant AXT3 and could grow in the presence of 75 mM NaCl.
