Revealing the structure of land plant photosystem II: the journey from negative‐stain EM to cryo‐EM

FEBS Letters, EarlyView.
Advances in cryo‐EM have revealed the detailed structure of Photosystem II, a key protein complex driving photosynthesis. This review traces the journey from early low‐resolution images to high‐resolution models, highlighting how these discoveries deepen our understanding of light harvesting and energy conversion in plants.

Exudates of dominant plants regulate rhizospheric soil total and available heavy metals and facilitates natural restoration succession in an abandoned metal mining area

Frontiers in Environmental Science
Soil degradation caused by activities such as mining is a severe global environmental issue that drastically disrupts ecosystems. Utilizing plants and their root secretions for ecological remediation is a crucial pathway to restoring these damaged lands.

Mapping the evolution of mitochondrial complex I through structural variation

FEBS Letters, EarlyView.
Respiratory complex I (CI) is crucial for bioenergetic metabolism in many prokaryotes and eukaryotes. It is composed of a conserved set of core subunits and additional accessory subunits that vary depending on the organism. Here, we categorize CI subunits from available structures to map the evolution of CI across eukaryotes. Respiratory complex I (CI)

Primordial non-gaussianities in single field inflation

, 2005
We calculate the three-point function for primordial scalar fluctuations in a single field inflationary scenario where the scalar field Lagrangian is a completely general function of the field and its first derivative.

Spatiotemporal and quantitative analyses of phosphoinositides – fluorescent probe—and mass spectrometry‐based approaches

FEBS Letters, EarlyView.
Fluorescent probes allow dynamic visualization of phosphoinositides in living cells (left), whereas mass spectrometry provides high‐sensitivity, isomer‐resolved quantitation (right). Their synergistic use captures complementary aspects of lipid signaling. This review illustrates how these approaches reveal the spatiotemporal regulation and quantitative

Mitigating cadmium toxicity in crops: Agronomic measures to regulate uptake and tolerance mechanisms

Plant Stress
Cadmium (Cd), a highly toxic heavy metal, disrupts all stages of crop growth and poses serious threats to human health through its accumulation in the food chain. To address this challenge, numerous studies explored a range of agronomic measures aimed at
