Energy transfer within phycocyanin trimers of Mastigocladus laminosus studied by picosecond time-resolved transient absorption spectroscopy [PDF]

, 1987
The transient absorption recovery induced in phycocyanin trimers by picosecond pulses of variable wavelength (570 — 620 nm) has been recorded and analyzed by applying a least-squares multi-exponential fit procedure.

Phycocyanobilin biosynthesis in Galdieria sulphuraria requires isomerization of phycoerythrobilin synthesized by bilin reductases

The FEBS Journal, EarlyView.
The biosynthesis of bilins, tetrapyrroles essential for light harvesting and sensing, is performed by specific enzymes (FDBRs). In Galdieria sulphuraria, both phycobiliprotein types bind phycocyanobilin, despite lacking the canonical synthesizing gene PCYA. Instead, PEBA and PEBB are encoded, producing phycoerythrobilin, proposed to be later isomerized

Key metabolites secreted by Chlorella vulgaris alleviate salt stress in soybean seedlings

Journal of Integrative Plant Biology, EarlyView.
Chlorella vulgaris secretes exosome‐derived linolenic acid and inosine, which alleviate salt stress and enhance salt tolerance in soybean seedlings by activating stress‐responsive signaling networks. ABSTRACT Soil salinization is a major abiotic stress factor that reduces soybean production.

Acridone Derivatives as Photosystem II Inhibitors: Synthesis, Herbicidal Activity, and Structure-Activity

Journal of the Brazilian Chemical Society
In this study, we report the synthesis of acridone derivatives and their potential as photosystem II (PSII) inhibitors, as well as their pre- and post-emergence herbicidal activities through chlorophyll a fluorescence and germination assays. Among the compounds tested for PSII activity, acridin-9(10H)-one showed the most promising results, reducing the

Cold comfort for change: Stream mats as biological indicators of ecosystem processes in the McMurdo Dry Valleys, Antarctica

Journal of Phycology, EarlyView.
Abstract Glacier‐fed streams (GFSs) make ideal systems for studying climate‐related changes. Some of the best‐studied GFSs are found in the McMurdo Dry Valleys (MDVs) of Antarctica, one of the Earth's coldest and driest deserts. Despite their harsh and isolated nature, MDV GFSs represent an oasis of life in a landscape visually devoid of it, with ...

Influence of prey concentration, light intensity, and temperature on the growth and ingestion of the mixotrophic dinoflagellate Pyrophacus horologium, a predator of the harmful species Heterocapsa niei

Journal of Phycology, EarlyView.
Abstract Pyrophacus horologium belongs to the family Pyrocystaceae and was recently identified as a mixotrophic dinoflagellate capable of feeding on other dinoflagellates. In this study, the growth and feeding responses of P. horologium were investigated under various environmental conditions by providing Heterocapsa niei, its preferred prey.

The unicellular green microalga Botryosphaerella sudetica links plant‐like light protection with an algal lifestyle

New Phytologist, EarlyView.
Summary Nonphotochemical quenching (NPQ) mechanisms fine‐tune light utilisation in the photosynthetic antenna, for example, in response to excess light, to prevent photodamage. NPQ comprises distinct mechanisms, all contributing to photoprotection but acting on different time scales.

Chloroplast acetyltransferase GNAT2 acts as a redox-regulated switch for state transitions in tomato

Molecular Horticulture
State transition is a dynamic process to balance the amount of light energy received by photosystem I (PSI) and photosystem II (PSII) so as to maintain an optimal photosynthetic yield and to minimize photo-damage in a fluctuating light environment ...
