@mc-caillaud.bsky.social's talk at #SLS26 suggests actin-mediated regulation allows flexible implementation of a shared core strategy, favouring division perpendicular to the growth axis and symmetric partitioning, while avoiding lateral wall anchoring. www.ens-lyon.fr/RDP/signalis...

Ever wondered what makes some alleles dominant (A) and others recessive (a) ? In our new paper, we explored how a series of recently discovered "dominance modifiers", genetic elements that have long remained elusive, achieve their regulatory function. journals.plos.org/plosgenetics...
journals.plos.org
Dominance modifiers at the Arabidopsis self-incompatibility locus retain proto-miRNA features and act through non-canonical pathways
Author summary Many plants avoid self-fertilization through a system of self-incompatibility, which allows them to recognize and reject their own pollen. In plants like those in the Arabidopsis family...
