Functional divergence of LhcSR and PsbS in zeaxanthin‐mediated non‐photochemical quenching
Summary To protect photosystem II from excess light, non‐photochemical quenching (NPQ) dissipates excess energy as heat. NPQ relies on trigger proteins, LhcSR in algae and PsbS in vascular plants, and the light‐regulated xanthophyll cycle, which interconverts violaxanthin and zeaxanthin through the opposite activities of violaxanthin de‐epoxidase and ...

Enhancing CRISPR/Cas‐Mediated Gene Knockout With Short Non‐Homologous Oligonucleotides
ABSTRACT Chlamydomonas reinhardtii is a model green microalga that has great industrial potential as a sustainable bio‐factory for recombinant protein and high‐value chemical production. Efficient genome editing tools are required to redesign this organism for synthetic biology applications. CRISPR‐Cas editing technologies have already been adapted for

Length-dependent disassembly maintains four different flagellar lengths in Giardia. [PDF]
With eight flagella of four different lengths, the parasitic protist Giardia is an ideal model to evaluate flagellar assembly and length regulation. To determine how four different flagellar lengths are maintained, we used live-cell quantitative imaging ...

Plants synthesize ergothioneine, showing a link to abiotic stress
Various plants possess ergothioneine biosynthetic genes and can synthesize this antioxidant, where increased EGT levels under abiotic stress conditions indicate protective functions. Abstract Ergothioneine (EGT) is a sulphur‐containing histidine derivative and a potent antioxidant that exhibits beneficial effects on human health.

Alternative outlets for sustaining photosynthetic electron transport during dark-to-light transitions. [PDF]
Environmental stresses dramatically impact the balance between the production of photosynthetically derived energetic electrons and Calvin-Benson-Bassham cycle (CBBC) activity; an imbalance promotes accumulation of reactive oxygen species and causes cell

Control Strategies in Guanine Biocrystallization
Biological guanine crystals produce spectacular photonic phenomena in animals and hold great promise as new, sustainable optical materials. We review how organisms precisely control the structure, morphologies, and resulting optical properties of these crystals using a set of ingenious ‘design’ strategies, including control of pH, template‐directed ...

A tale of three taxes: photo-gyro-gravitactic bioconvection [PDF]
The term bioconvection encapsulates the intricate patterns in concentration, due to hydrodynamic instabilities, that may arise in suspensions of non-neutrally buoyant, biased swimming microorganisms. The directional bias may be due to light (phototaxis),
