Mushroom meiosis; Comparisons of a multicellular mushroom with its unicellular yeast relatives reveals a conserved meiosis pathway, suggesting that meiotic genes are more conserved than non-meiotic genes, and more so than previously believed.C.

In the first genomic analysis of a multicellular brown alga, researchers see an increase in membrane-spanning receptor kinases, relative to their unicellular diatom relatives. The kinases are a protein family involved in cellular differentiation and patterning in both animals and green plants, suggesting this family of proteins may have been key to the evolution of multicellularity in all three lineages.
