Charting the native architecture of Chlamydomonas thylakoid membranes with single-molecule precision
eLife, 2020 Thylakoid membranes scaffold an assortment of large protein complexes that work together to harness the energy of light. It has been a longstanding challenge to visualize how the intricate thylakoid network organizes these protein complexes to finely ...

The Role of Phosphorylation Dynamics of CURVATURE THYLAKOID 1B in Plant Thylakoid Membranes [PDF]
Plant Physiology, 2019 Thylakoid membranes in land plant chloroplasts are organized into appressed and nonappressed membranes, which contribute to the control of energy distribution between the two photosystems (PSI and PSII) from the associated light-harvesting complexes (LHCs).

Membrane-Specific Targeting of Tail-Anchored Proteins SECE1 and SECE2 Within Chloroplasts.
Frontiers in Plant Science, 2019 Membrane proteins that are imported into chloroplasts must be accurately targeted in order to maintain the identity and function of the highly differentiated internal membranes.

Advanced Science, EarlyView.High light exposure triggers an epidermis‐specific remodeling of mitochondria and ER in Arabidopsis, driven by chloroplast‐derived signals. Live‐cell imaging shows that HL rapidly suppresses mitochondrial motility, followed by fusion‐driven elongation and ER cisternal expansion.

Advanced Science, EarlyView.ABSTRACT Precise transgene‐free gene upregulation remains a challenge in crop biotechnology, as conventional enhancers often exceed CRISPR‐mediated knock‐in size constraints and face regulatory hurdles. Here we establish a foundational cross‐species resource of compact transcriptional enhancers developed via STEM‐seq, a high‐throughput screening ...

Thylakoid membrane function in heterocysts
Biochimica et Biophysica Acta (BBA) - Bioenergetics, 2016 Multicellular cyanobacteria form different cell types in response to environmental stimuli. Under nitrogen limiting conditions a fraction of the vegetative cells in the filament differentiate into heterocysts. Heterocysts are specialized in atmospheric nitrogen fixation and differentiation involves drastic morphological changes on the cellular level ...

Biotechnology and Bioengineering, EarlyView.ABSTRACT Recombinant protein expression in heterologous biological systems is an expanding field in synthetic biology. Photosynthetic organisms have the potential to provide an efficient low‐cost platform for recombinant protein production because they require minimal growth nutrients and are less susceptible to zoonotic and other contaminants ...

Electron Microscopy Views of Dimorphic Chloroplasts in C4 Plants
Frontiers in Plant Science, 2020 C4 plants enhance photosynthesis efficiency by concentrating CO2 to the site of Rubisco action. Chloroplasts in C4 plants exhibit structural dimorphism because thylakoid architectures vary depending on energy requirements. Advances in electron microscopy
