Stunning new scan data of an enigmatic fish from the Early Devonian of Australia, Ligulalepis, is identified as a stem osteichthyan, specifically, as the sister taxon to the 'psarolepids' plus crown osteichthyans.
Yeast cell size homeostasis is not controlled by a G1-specific mechanism alone but is likely to be an emergent property resulting from the integration of several mechanisms that coordinate cell and bud growth with division.
Seipin oligomers dynamically interact with small, nascent lipid droplets near the endoplasmic reticulum to convert them into larger, mature lipid droplets in a newly identified step of lipid droplet formation.
A basidiomycete yeast closely related to fungal smuts is an antagonistic microbe in the Arabidopsis leaf phyllosphere that inhibits infection by Albugo laibachii via a GH25 hydrolase with lysozyme activity.
Live imaging and genetic analyses revealed that notochord vacuoles play a critical role in spine morphogenesis by absorbing vertebral bone growth, thus implicating notochord mechanics in congenital scoliosis.
