Melatonin induced changes in photosynthetic efficiency as probed by OJIP associated with improved chromium stress tolerance in canola (Brassica napus L.)

Heliyon, 2020
Chromium toxicity is considered as a major problem for agricultural soil that reduced crop productivity by affecting photosynthetic tissues. Exogenous application of melatonin can alleviate the adverse effects of chromium toxicity on plant growth ...

Exploring the structure of the N-terminal domain of CP29 with ultrafast fluorescence spectroscopy [PDF]

, 2009
A high-throughput Förster resonance energy transfer (FRET) study was performed on the approximately 100 amino acids long N-terminal domain of the photosynthetic complex CP29 of higher plants. For this purpose, CP29 was singly mutated along its N-terminal

Mixed Litter Decomposition Drives Functional Gene Rearrangement in the Microbial Carbon Cycle

Land Degradation &Development, EarlyView.
ABSTRACT Understanding how mixed‐species litter decomposition regulates microbial communities and carbon cycling is vital for guiding ecosystem restoration and climate change mitigation, as it is a key process for nutrient cycling and carbon sequestration. A 15‐month field experiment compared single‐species (Pinus sylvestris var.

Spectroscopic characterization of the spinach Lhcb4 protein (CP29), a minor light‐harvesting complex of photosystem II [PDF]

European Journal of Biochemistry, 1999
A spectroscopic characterization is presented of the minor photosystem II chlorophyll a/b‐binding protein CP29 (or the Lhcb4 protein) from spinach, prepared by a modified form of a published protocol [Henrysson, T., Schroder, W. P., Spangfort, M. & Akerlund, H.‐E. (1989) Biochim. Biophys. Acta977, 301–308].

Comparison of the α and β isomeric forms of the detergent n-dodecyl-D-maltoside for solubilizing photosynthetic complexes from pea thylakoid membranes [PDF]

, 2012
Mild non-ionic detergents are indispensable in the isolation of intact integral membrane proteins and protein-complexes from biological membranes. Dodecylmaltoside (DM) belongs to this class of detergents being a glucoside-based surfactant with a bulky ...

Leaf heat tolerance in a native Californian shrub responds in expected and unexpected ways to differences in range, season, and sunlight exposure

PLANTS, PEOPLE, PLANET, EarlyView.
Earth's ecosystems are experiencing wide‐ranging impacts from global climate change, including increased average and extreme temperatures. These temperature shifts can drastically affect plant physiology, threatening the future of even common plant species. Here, we focus on photosynthetic function in a native Southern California shrub species.

Single and Double Knockouts of the Genes for Photosystem I Subunits G, K, and H of Arabidopsis [PDF]

, 2002
Photosystem I (PSI) of higher plants contains 18 subunits. Using Arabidopsis En insertion lines, we have isolated knockout alleles of the genes psaG, psaH2, and psaK, which code for PSI-G, -H, and -K.

Plant responses to iron nutrition with emphasis on the underutilized crop tef (Eragrostis tef): A review

PLANTS, PEOPLE, PLANET, EarlyView.
Iron (Fe) deficiency limits the physical health, cognitive development, and economic output of billions of people globally, especially children and productive‐age women. Tef is an underutilized and stress‐resilient crop, which is becoming popular for its grains containing high bioavailable Fe and has the potential to mitigate Fe deficiency.
