I found that H2O2 treatment of Petunia flowers creates a "nightsky" like pattern 😯 It's known oxidation degrades anthocyanins, but the pattern was unexpected!

Growth of a seedling🌱 The first two "true leaves" of a seedling grow from the meristem, a region of small undifferentiated cells between the two embryonic leaves, or cotyledons. These are usually covered in spiky trichomes as they are vulnerable to herbivory by insects.

Leaf infiltration is a widely used technique in plant science for delivering Agrobacterium or chemicals directly to plant cells 🍃🧬 For those who do it regularly, there’s a satisfaction in watching the liquid flow seamlessly through the leaf's airspaces—when done well..

Fluorescent Protein Biosensors Quick Guide! 🧵 FP Biosensors are genetically encoded tools that measure analytes (X) which either directly or indirectly affect their spectral properties. Analytes can affect the fluorophore intrinsically or through extrinsic sensing domains fused to the FP. Measurements are calculated as the signal of a single channel (intensiometric) or as the ratio of signal from two channels (ratiometric).

Förster resonance energy transfer (FRET) Visual Guide 🧵 Resonance energy transfer occurs when excess energy from an excited chromophore (donor) is transferred to a nearby chromophore (acceptor) within around 10nm. This phenomena has been exploited for cell biology applications such as FRET biosensors and FRET-FLIM that measure protein-protein interactions.

Gemma growth of the liverwort, Marchantia polymorpha (10-day timelapse). The gametophyte grows with repeated dichotomous branching at the apex and long single-celled rhizoids emerging mostly from the ventral surface. Such a cool plant.

Growth of Anthoceros agrestis, an emerging hornwort model organism! To my knowledge, this is the first timelapse of Anthoceros- perhaps because it is so small (video 1cm in width) and grows so slowly (3 weeks shown in 10 seconds). Thanks, @Alon_Israeli for the plant :)

Circumnutation is a common plant behavior in which plants rotate around a central axis, allowing exploration of the surrounding 3D space. This movement is the achievement of coordinated cell growth and turgor pressure changes, and was first analyzed in detail by Charles Darwin.

Germination of an Arabidopsis seed over 7 days. First to emerge is the radicle (embryonic root) followed by the hypocotyl and cotyledons (embryonic shoot/leaves). Growth in the hypocotyl is solely driven by cell expansion making it all wiggly and cute.
