Programmed cell death and redox metabolism protect Chlamydomonas reinhardtii populations from the galactic cosmic environment on the Artemis-1 mission [PDF]

Scientific Reports
On the Artemis I mission, Chlamydomonas reinhardtii, a green unicellular flagellate alga, was exposed to the galactic cosmic environment. A new flight hardware termed “Moonshot” was designed, built, and flown.

Evaluation of visible-light wavelengths that reduce or oxidize the plastoquinone pool in green algae with the activated F0 rise method

Photosynthetica, 2022
We recently developed a chlorophyll a fluorescence method (activated F0 rise) for estimating if a light wavelength preferably excites PSI or PSII in plants.

Illuminating the diversity of carotenoids in microalgal eyespots and phototaxis

Plant Signaling & Behavior, 2023
Photosynthetic organisms biosynthesize various carotenoids, a group of light-absorbing isoprenoid pigments that have key functions in photosynthesis, photoprotection, and phototaxis.

Improving the co-production of triacylglycerol and isoprenoids in Chlamydomonas [PDF]

Biofuel Research Journal, 2020
Biodiesel and natural products derived from microalgae require a smaller land area and have higher production rates compared to plants and animals and has recently attracted considerable interest.

Genetics of a de novo origin of undifferentiated multicellularity [PDF]

Royal Society Open Science, 2018
The evolution of multicellularity was a major transition in evolution and set the stage for unprecedented increases in complexity, especially in land plants and animals.

LETTER TO EDITORLight regulation of photosynthetic light harvesting doubles the biomass yield in the green alga Chlamydomonas

Photosynthetica, 2020
Due to the overall low thermodynamic efficiency (1-4%) of photosynthesis (Ort et al. 2011, Subramanian et al. 2013) and its impact on crop productivity, substantial efforts are being made to engineer photosynthesis to improve its light use and carbon ...

WDR90 is a centriolar microtubule wall protein important for centriole architecture integrity

eLife, 2020
Centrioles are characterized by a nine-fold arrangement of microtubule triplets held together by an inner protein scaffold. These structurally robust organelles experience strenuous cellular processes such as cell division or ciliary beating while ...

Identifying RNA splicing factors using IFT genes in Chlamydomonas reinhardtii [PDF]

Open Biology, 2018
Intraflagellar transport moves proteins in and out of flagella/cilia and it is essential for the assembly of these organelles. Using whole-genome sequencing, we identified splice site mutations in two IFT genes, IFT81 (fla9) and IFT121 (ift121-2), which ...

Evolution of cell size control is canalized towards adders or sizers by cell cycle structure and selective pressures

eLife, 2022
Cell size is controlled to be within a specific range to support physiological function. To control their size, cells use diverse mechanisms ranging from ‘sizers’, in which differences in cell size are compensated for in a single cell division cycle, to ‘

Characterization of Phytoene Desaturase Knockout Carotenoid-Deficient Microalgal Mutants Generated by Cas9-Ribonucleoprotein Complexes. [PDF]

Physiol Plant
ABSTRACT Phytoene desaturase (PDS; EC 1.3.5.5) is a key enzyme of the carotenoid biosynthetic pathway, catalyzing the desaturation of phytoene, precursor of all carotenoids. In this study, several PDS‐knockout (PDS‐KO) transformants of the chlorophyte microalga Chlamydomonas reinhardtii were generated using a reverse genetics strategy. Two single guide
