Background: Calmodulin-binding transcription activator (CAMTA) proteins play significant roles in signal transduction, growth and development, as well as abiotic stress responses, in plants. Understanding their involvement in the low-temperature stress response of teak is vital for revealing cold resistance mechanisms.
Results: Through bioinformatics analysis, the CAMTA gene family in teak was examined, and six CAMTA genes were identified in teak.

Understanding the mechanisms that underlie the adaptive response of ectotherms to rising temperatures is key to mitigate the effects of climate change. We assessed the molecular and physiological processes that differentiate between rainbow trout (Oncorhynchus mykiss) with high and low tolerance to acute thermal stress. To achieve our goal, we used a critical thermal maximum trial in two strains of rainbow trout to elicit loss of equilibrium responses to identify high and low tolerance fish.

α-Arbutin is the fourth generation whitening factor in the field of cosmetics, which can block the synthesis of melanin in epidermal cells and has the advantages of good stability and less toxic side effects. Moreover, α-arbutin has potential application value in food, medicine, and other fields. However, the extraction yield from plant tissues is relatively low, which restricts its application value.

In this study, we demonstrate a unique and promising approach to access peptide-based diverse nanostructures in a single gelator regime that is capable of exhibiting different surface topographies and variable physical properties, which, in turn, can effectively mimic the extracellular matrix (ECM) and regulate variable cellular responses. These diverse nanostructures represent different energy states in the free energy landscape, which have been created through different self-assembling pathways by providing variable energy inputs by simply altering the gelation induction temperature from 40 °C to 90 °C. The highly entangled network structure with long fibers was created by higher energy inputs, , inducing the gelation at a higher temperature in the 70-90 °C range, whereas the less entangled nanoscale network with short fibers was obtained at a lower gelation induction temperature of 40-60 °C.

Article Synopsis
- The study focuses on the role of the DELLA protein PmRGL2 in regulating dormancy and flowering in Prunus mume, a type of temperate fruit tree.
- Genetic and protein interaction analyses revealed that PmRGL2 interacts with PmFRL3, influencing the expression of flowering-related proteins like PmSVP and PmSVP-like.
- The proposed mechanism suggests that environmental signals like gibberellin (GA) and chilling temperatures affect the PmRGL2/PmFRL3 complex, leading to changes in flowering timing by regulating PmSVP and PmSVP-like activity.
