"These data give us a new insight into the #evolutionary relationships between wood nanostructure and the cell wall composition, which differs across the lineages of #angiosperm and #gymnosperm plants. By identifying the potential selective pressures for the evolution of macrofibril morphology, our work provides the basis for selection or engineering for desirable wood properties and may open up routes for improved #carbon #sequestration in plantation forests."
In our Jurassic episode we talked about the 2018 discovery of Ledumahadi Mafube and its departure from the typical column-like leg structure. Get a load of those elbows!

Self-incompatibility (SI) is a widespread intraspecific reproductive barrier in flowering plants, a system for rejecting self-pollen to prevent seed set after self-pollination. In Solanaceae, Plantaginaceae, Rosaceae, and Rutaceae, the SI system is controlled by a single polymorphic S-locus that encodes the linked pollen factor S-locus F-box box proteins (SLFs) and pistil factor S-RNase components.
