In-planta ancestral protein resurrection of the female determinant of self-incompatibility specificity in Arabidopsis halleri demonstrates that two allelic variants currently segregating as distinct receptor-ligand combinations diverged through an asymmetrical process.
Early seeds without cupules evolved functions in wind dispersal and probable photosynthetic nutrition and three-winged seeds are more adapted to wind dispersal than seeds with one, two, or four wings.
KATANIN1 in stigma papilla cells prevents disordered pollen tube growth and straightens pollen tube direction, allowing the pollen tube to find its correct path to the underlying female tissues.
Annual crop communities are able to adapt towards reduced competition and/or increased facilitation in response to their neighboring diversity after only two generations.

High degree of clonal persistence and excess of inter-individual convergence are observed in human memory B cell repertoires, along with signatures of both negative and positive selection in most abundant clonal lineages.
The endopeptidases ECS1 and ECS2 regulate double fertilization and their modulation is a powerful tool for the induction of haploids and the formation of triparental plants, which are two agronomically relevant breeding targets.
