Chemotactic responses of Chlamydomonas reinhardtii. [PDF]

open access: yesMolecular and Cellular Biology, 1981
A capillary chemotaxis assay revealed that among a wide range of inorganic and organic chemicals, only ammonium ion (NH4+) could serve as an attractant of Chlamydomonas reinhardtii. NH4+ (10(-2) M) gave the maximum response, with up to a 15-fold increase in accumulated algae being measured. No repellents for the chlorophyte were detected.

Post‐LECA Origin and Diversification of an Axonemal Outer Arm Dynein Motor

open access: yesCytoskeleton, EarlyView.
ABSTRACT Dyneins were present in the last eukaryotic common ancestor (LECA) and play key roles in eukaryotic biology. Axonemal dyneins form the inner and outer arms that power ciliary beating, and it has long been recognized that outer arms in some organisms contain two different heavy chain motors, whereas those from other species contain a third unit

An Update on the Metabolic Roles of Carbonic Anhydrases in the Model Alga Chlamydomonas reinhardtii

open access: yesMetabolites, 2018
Carbonic anhydrases (CAs) are metalloenzymes that are omnipresent in nature. CAs catalyze the basic reaction of the reversible hydration of CO2 to HCO3− and H+ in all living organisms. Photosynthetic organisms contain six evolutionarily different classes

Marine Macroalgae as a Safe Healthy Food While Meeting Food Security Challenges Arising From Climate Changes

open access: yesFood Safety and Health, EarlyView.
Planned harvesting and processing of marine macroalgae could meet future global food needs and mitigate fuel‐originated carbon dioxide responsible for climate change. Microalgal foods are nutritious and safe. The utilization of macroalgae would avoid environmental problems arising from the release of overgrowing macroalgae caused by heatwaves, which ...

Influence of Age and Exposure Pathway on Copper and Cadmium Mixture Toxicity: A Study on Daphnia magna

open access: yesEnvironmental Toxicology, EarlyView.
ABSTRACT Metal contamination in aquatic ecosystems poses substantial risks to freshwater organisms, with mixture effects often deviating from predictions based on single‐metal toxicity. Understanding how age‐specific sensitivities and multiple exposure pathways influence mixture effects is critical for accurate risk assessment.

Chlamydomonas IFT25 is dispensable for flagellar assembly but required to export the BBSome from flagella

open access: yesBiology Open, 2017
Intraflagellar transport (IFT) particles are composed of polyprotein complexes IFT-A and IFT-B as well as cargo adaptors such as the BBSome. Two IFT-B subunits, IFT25 and IFT27 were found to form a heterodimer, which is essential in exporting the BBSome ...

Expression and molecular analysis of phbB gene in Chlamydomonas reinhardtii

open access: yes, 2004
The expression vector containing phbB and ble genes was constructed and transformed into cell-wall-deficient strain Chlamydomonas reinhardtii CC-849 by the glass-head method.

Co‐Culture of Mammalian Cells and Photosynthetic Microorganisms for Oxygen Supply in Engineered Tissues

open access: yesCell Proliferation, EarlyView.
Continuous 28‐day light exposure alters behaviours of articular cartilage progenitor cells (ACPCs) and mesenchymal stromal cells (MSCs). Co‐culture with Leptolyngbya and Synechococcus does not adversely affect the chondrogenic capacity of ACPCs over a 28‐day period, in contrast to co‐culture with Chlorella.
