Diffusion-Based Synthetic Pretraining for Root Segmentation in Rhizotron Images

This paper generates synthetic rhizotron images using diffusion models and shows that pretraining on these images improves root segmentation performance, especially when real annotations are limited.

A complex balance: PLETHORA - JANUS ratiometry explains the PLETHORA dosage regeneration paradox

The paper explains how the balance between PLETHORA protein complexes and unbound PLETHORA determines regenerative competence in Arabidopsis roots, revealing a ratiometric mechanism for transcription factor dosage.

The MicroTron: a microfluidic platform for single cell studies in P. patens

The paper introduces the MicroTron, a microfluidic platform for applying chemicals to single cells in moss protonemata to study cellular responses.

A PLETHORA transcription factor shapes cucumber shoot architecture

This study investigates the role of CsPLT3/7 transcription factors in cucumber shoot development, finding conserved and diversified functions across species.

Style deflection is determined by the handedness of phyllotaxis and auxin-induced differential cell elongation in a species with mirror-image flowers

This study identifies that floral handedness in Cyanella alba is determined by phyllotactic spiral direction and auxin-induced differential cell elongation, not genetics.

Steep logarithmic increase of genetic variation in natural Arabidopsis thaliana accessions across geographic scales

The paper compares genetic variation across different geographic scales in Arabidopsis thaliana, finding that local populations contain a significant proportion of continental variation and a logarithmic relationship between genetic and geographic distance.

A microtubule-based mechanism predicts cell division orientation in plant embryogenesis

The paper identifies three rules governing microtubule organization in plant embryos to predict cell division orientation based on cell shape and auxin effects.
