Plant Carbonic Anhydrases, their Role in Stress Defense and Possible Practical Use [PDF]

Journal of Stress Physiology & Biochemistry, 2018
The review presents data on the distribution of carbonic anhydrases in photosynthetic organisms and their location in cellular compartments. The functions of carbonic anhydrases to provide a high photosynthesis rate as well as their participation in ...

Pierceable, Water‐Resistant, and Transparent Nanofilm Electrodes Comprising Carbon Nanotubes for Long‐Term Monitoring of Plant Electrophysiology

Advanced Science, EarlyView.
Ultra‐flexible electrodes composed of single‐walled carbon nanotubes on a polymeric substrate exhibit excellent transparency, water resistance, and conformability to hairy surfaces. These non‐invasive nanofilms are easily pierced by trichomes, overcoming the structural barriers in plant electrophysiology.

Ultrastructure changes of seedlings of Kosteletzkya virginica under waterlogging conditions

Biologia Plantarum, 2011
The changes in ultrastructure of leaf cell in waterlogged Kosteletzkya virginica seedlings were observed by transmission electron microscope. During waterlogging, the chloroplasts turned into a round shape and their volume was gradually reduced ...

Biolipid Film‐Fused Electrochemiluminescence for Multipurpose In Situ Bioassays

Advanced Science, EarlyView.
An ECL‐emissive, membrane‐interactive scaffold was fabricated, and facilely fused with natural and non‐native phospholipids into multifactorial mimicries of cytomembranes and vesicles for in vitro representative membrane‐process probing. Such a biointerface‐based, state‐sensitive ECL paradigm not only pinpointed proximal phenomena, including channeling

Oxygen-evolving diatom thylakoid membranes

Biochimica et Biophysica Acta (BBA) - Bioenergetics, 1998
Two protocols were developed that yielded purified oxygen-evolving thylakoid membranes from the diatom Cylindrotheca fusiformis. One protocol employed sonication, while the second involved French press lysis of protoplasts formed by brief culture of cells in a cation-depleted medium.

Physiological and ultrastructural effects of lead on tobacco

Biologia Plantarum, 2012
The effects of lead toxicity on leaf gas exchange, chlorophyll content, chlorophyll fluorescence, chloroplast ultrastructure, and opening of stomata were examined in tobacco (Nicotiana tabacum L.) plants.

Sensing and Filtering Environmental Fluctuations: The Case of Biomolecular Condensates in Plants

Advanced Science, EarlyView.
The diversity of plant condensates reflects constraints of sessile organisms to coordinate postembryonic development with environmental adaptation. This review examines how plants employ condensates to integrate temperature, light, redox, and nutrient signals.

Uni‐site ATP synthesis in thylakoids

FEBS Letters, 1990
Uni‐site ATP synthesis was measured with thylakoids. The membrane‐bound ATP‐synthase, CF0F1 was brought into the active, reduced state by illumination in the presence of thioredoxin, dithiothreitol and phosphate. This enzyme contains two tightly bound ATP per CFoF1. ATP was released from the enzyme when ADP was added in substoichiometric amounts during

Mimicking a Light‐Harvesting Complex to Accelerate Photooxidation in Asymmetric Lipid Membrane Nanoreactors

Angewandte Chemie International Edition, EarlyView.
Biomimetic liposome nanoreactors mimicking natural light‐harvesting complexes enable efficient photooxidation of NADH. Membrane‐anchored fluorescein transfers energy via FRET to membrane anchored eosin Y, oxidizing NADH. While symmetric membranes show little improvement, asymmetric chromophore distribution enhances photooxidation rates by up to 27 ...

Biomaterial design strategies for enhancing mitochondrial transplantation therapy

BMEMat, EarlyView.
Biomaterials to facilitate mitochondrial transplantation therapy: biomaterials as barriers to protect mitochondria from pathophysiological microenvironments, like osmotic stress caused by the excessive concentration of calcium ion, reactive oxygen species, and advanced glycation end products; biomaterials integrating with biochemical cues to improve ...
