Wounding triggers callus formation via dynamic hormonal and transcriptional changes
Wounding is a primary trigger of organ regeneration, but how wound stress reactivates cell
proliferation and promotes cellular reprogramming remains elusive. In this study, we …

Increased gene expression variability hinders the formation of regional mechanical conflicts leading to reduced organ shape robustness
To relate gene networks and organ shape, one needs to address two wicked problems: i)
Gene expression is often variable locally, and shape is reproducible globally; ii) gene …
