Radical cell identity bifurcation in Saccharina embryos coincides with the expression of newly acquired genes.

The paper studies early embryogenesis in Saccharina latissima, finding radical cell identity changes and gene expression patterns linked to evolutionary novelty.

Armadillo Repeat Only Proteins Are Essential Activators of Plant CNGC Channels.

This study identifies ARO proteins as essential activators of plant CNGC channels, revealing their role in calcium signaling through interaction with the Calmodulin-binding IQ domain.

MUM, a maternal unknown message, inhibits early establishment of the mediolateral axis in the embryo of the kelp Saccharina latissima

This paper investigates the role of a maternal signal (MUM) in establishing growth axes during kelp embryogenesis, showing that MUM inhibits medio-lateral axis formation and requires direct contact with the stalk.

The longitudinal growth of the embryo of the kelp Saccharina depends on actin filaments that control the formation of an alginate corset in the cell wall

The paper shows that actin filaments control alginate distribution in kelp embryos, forming a corset that restricts growth and establishes the apico-basal axis.
