Unexpected Dual Function of Plant YUCCA Enzymes Links Chlorophyll Catabolism to Auxin Homeostasis

Angewandte Chemie, EarlyView.
YUCCA enzymes are well known to catalyze the main step of auxin biosynthesis in plants. Here, a hitherto undescribed dual function was discovered, revealing that some YUCCAs also act in chlorophyll degradation. In vitro feedback regulation furthermore suggests a link between chlorophyll degradation and hormone homeostasis and a physiological role of ...

Improved iron acquisition of Astragalus sinicus under low iron-availability conditions by soil-borne bacteria Burkholderia cepacia

Journal of Plant Interactions, 2018
Soil bacteria can assist plant growth and increase uptake of nutrient elements, the question arises as to whether beneficial soil microbes confer augmented iron (Fe) content of host plants under Fe limited conditions.

Cysteine-Mediated Extracellular Electron Transfer of Lysinibacillus varians GY32

Microbiology Spectrum, 2022
Microbial extracellular electron transfer (EET) is essential in many natural and engineering processes. Compared with the versatile EET pathways of Gram-negative bacteria, the EET of Gram-positive bacteria has been studied much less and is mainly limited

Absence of a dose-rate effect in the transformation of C3H 10T1/2 cells by α-particles [PDF]

, 1987
The findings of Hill et al. (1984) on the greatly enhanced transformation frequencies at very low dose rates of fission neutrons induced us to perform an analogous study with -particles at comparable dose rates. Transformation frequencies were determined

Riboflavin deficiency leads to irreversible cellular changes in the RPE and disrupts retinal function through alterations in cellular metabolic homeostasis

Redox Biology, 2022
Ariboflavinosis is a pathological condition occurring as a result of riboflavin deficiency. This condition is treatable if detected early enough, but it lacks timely diagnosis.

Linear Dichroism and Orientation of the Phycomyces Photopigment [PDF]

, 1973
The greater sensitivity of a cylindrical Phycomyces sporangiophore to blue light polarized transversely rather than longitudinally is a consequence of the dichroism and orientation of the receptor pigment.

An Enzyme‐Like Catalyzed Nanosheets for Redox Stress Oscillation Therapy Against Bacterial Infections

Advanced Science, EarlyView.
Bacterial biofilms form a physicochemical barrier. Their dense network structure and redox homeostasis confer high resistance to antimicrobial treatments and immune‐mediated killing and clearance. In this study, SnSe nanosheets with enzyme‐like properties and piezoelectric catalysis can oscillate to regulate bacterial redox homeostasis and improve the ...
