Vestigial Plastids in Parasitic Plants: Evolutionary Remnants or Adaptive Innovations?

Plant, Cell &Environment, Volume 49, Issue 8, Page 5401-5420, August 2026.
ABSTRACT Throughout the evolutionary history of plants, chloroplasts originating from a cyanobacterial endosymbiosis have undergone remarkable adaptation and specialization, giving rise to a multitude of plastid types. The evolution toward parasitism in plants represents a particularly extreme case of such specialization.

Sulfadiazine selection enables high‐efficiency transformation in Nannochloropsis and Microchloropsis

The Plant Journal, Volume 127, Issue 3, August 2026.
SUMMARY Nannochloropsis and Microchloropsis are important as eustigmatophyte model organisms and the production of high‐value lipids. Efficient selectable markers are indispensable for genetic engineering to study and improve production yield of these species.

Spectroscopic Investigation of the In Vivo Light‐Dependent Photodynamics of the Marine Diatom Phaeodactylum tricornutum

ChemPhysChem, Volume 27, Issue 13, 14 July 2026.
µm fourier transform infrared (FTIR) image, 442 nm Raman of the Si–O of the silica‐based frustule at 472 cm−1, and UV–vis of Phaeodactylum tricornutum cells. Marine diatoms are responsible for fixing CO2 into organic carbon and contribute to the regulation of global climate.

Accessing Sn≥2 States of a TADF Emitter by Femtosecond NIR Spectroscopy

Chemistry – A European Journal, Volume 32, Issue 26, 11 July 2026.
The depicted thermally activated delayed fluorescence (TADF) emitter was studied by femtosecond near‐infrared (NIR) spectroscopy. A prominent NIR transition was shown to be strongly solvent‐dependent, with implication for intersystem crossing in the compound.
