Integrated analysis of transcriptome and proteome provides novel insights into the response mechanisms of maca (Lepidium meyenii Walp.) to UV-B radiation

open access: yesEcotoxicology and Environmental Safety
UV-B radiation is a significant environmental factor that affects a wide range of biological processes in plants. Maca (Lepidium meyenii Walp.), a critical herbaceous plant native to high altitudes, shows strong adaptation to environmental stimuli ...

Identification and characterization of a gene conferring stress resistance in Escherichia coli and cyanobacteria

open access: yesFEBS Open Bio, EarlyView.
Functional screening identified PcSyn14890, a cyanobacteria‐specific protein that enhances growth and stress resistance in E. coli and Synechocystis PCC6803. Although we expected it to function as a molecular chaperone, it was unable to protect against thermal aggregation of GAPDH.

Chronobiology of Cancer: How Aging Fuels Oncogenesis at the Molecular Level

open access: yesAging and Cancer, EarlyView.
This graphical abstract illustrates the key biological pathways linking aging with cancer development and progression. In the upper left, cumulative exposure to ultraviolet radiation, toxins, and reactive oxygen species (ROS) causes DNA damage and genomic instability, whereas age‐related decline in repair mechanisms, such as ATM/ATR, BER, and NER ...

Hormonal regulation of crop adaptation to UV-B radiation stress: implications for UV-B-Resistant crop varieties and sustainable agriculture

open access: yesDiscover Agriculture
Ultraviolet-B (UV-B: 280–315 nm) radiation stress severely compromises crop quality and productivity, necessitating the development of effective adaptive mechanisms. For plants to coordinate these adaptive responses, hormonal control is crucial. However,

Effects of ultraviolet-B radiation on the reproduction, germling growth, and physio-biochemical characteristics of green alga Ulva pertusa (Chlorophyta)

open access: yesFrontiers in Marine Science
IntroductionEnhanced ultraviolet-B (UV-B, 280-320nm) radiation caused by ozone depletion is a global environmental issue. Ulva pertusa Kjellman (Chlorophyta) is often found in shallow intertidal environments exposed to ambient solar radiation. Therefore,
