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).

$"Little Flower" is a piece I dreamed of for over a year, and at last, it’s alive. A 10k × 10k Cryo-SEM portrait of my micro-rose. A sculpture of cells... fractured and frozen in time.$

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.

While animal movements are largely regulated through electrical signals and muscle contractions, plant movements are controlled primarily through hormone signaling, changes in turgor pressure, and cell wall loosening. Plant growth behavior operates on another timescale🌱⌛️

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.
