Cullin-based RING E3 ligases that use BTB/POZ-MATH (BPM) proteins as substrate receptors have been established over the last decade as critical regulators in plant development and abiotic stress tolerance. As such they affect general aspects of shoot and root development, flowering time, embryo development, and different abiotic stress responses, such as heat, drought and salt stress. To generate tools that can help to understand the role of CRL3 E3 ligases in plants, we developed a novel system using two conserved protein-binding motifs from BPM substrates to transiently block CRL3 activity. The work investigates and this novel approach, and shows that it can affect stress tolerance in plants as well as developmental aspects. It thereby can serve as a new tool for studying this E3 ligase in plants.

Background: High-temperature environment can cause acute kidney injury affecting renal filtration function. To study the mechanism of renal injury caused by heat stress through activates TLR4/NF-κB/NLRP3 signaling pathway by disrupting the filtration barrier in broiler chickens. The temperature of broilers in the TN group was maintained at 23 ± 1 °C, and the HS group temperature was maintained at 35 ± 1℃ from the age of 21 days, and the high temperature was 10 h per day, and one broiler from each replicate group at the age of 35 and 42 days was selected for blood sampling, respectively.

Peptidyl prolyl cis/trans isomerases (PPIases), a ubiquitously distributed superfamily of enzymes, associated with signal transduction, trafficking, assembly, biofilm formation, stress tolerance, cell cycle regulation, gene expression and tissue regeneration, is a key regulator of metabolic disorders and microbial virulence. This review assumes an integrative approach, to provide a holistic overview of the structural and functional diversity of PPIases, examining their conformational dynamics, cellular distribution, and physiological significance. We explore their intricate involvement in cellular processes and virulence modulation in both eukaryotic and prokaryotic systems.

Calcium-dependent protein kinases (CDPKs) are very effective calcium signal decoders due to their unique structure, which mediates substrate-specific [Ca] signalling through phosphorylation. However, Ca-dependence makes it challenging to study CDPKs. This work focused on the effects of the overexpression of native and modified forms of the AtCPK1 gene on the tolerance of tobacco plants to heat and cold.

Extreme conditions, such as cold and high humidity in northeast China's high-latitude maize region, can hinder crop yield and stability during the vegetative stage. However, there is a paucity of research examining the effects of simultaneous cold and high humidity stress on plant responses. In this study, we characterized the acclimation of JD558 (cold- and high humidity-sensitive hybrid) and JD441 (cold- and high humidity-tolerant hybrid) to stress at sowing caused by cold (4 °C), high humidity (25%), and their combined stress for five days, using physiological measurements and metabolomics during the stress treatments and recovery stages.
