Figure 1. Discovery of actomyosin function in division plane orientation in dividing guard mother cells of onion cotyledons in 1974. (a) A guard mother cell undergoes a symmetric cell division to produce two guard cells by having the cell plate (arrowheads) oriented along the longitudinal axis of the cotyledon. (b) After treatment with the actin-depolymerizing agent cytochalasin, a guard mother cell forms a misoriented cell plate (arrowheads). Micrographs are from a published study [10]. Scale bar, 5 μm.

🌱 Structural variants control sex-specific flowering in walnuts and hickories, offering parallel but distinct evolutionary solutions. (Jeffrey S. Groh, Diane Vik, Matthew Davis, J. Grey Monroe, Kristian Stevens, Patrick J. Brown, Charles Langley, and Graham Coop)
▶️ www.science.org/doi/full/10....

Multiple genetic mechanisms control a balanced polymorphism for flowering order in walnuts and hickories.
In Juglans (top left) and Carya, two morphs show complementary temporal separation between male and female flowering (heterodichogamy). Mating types are controlled by two nonhomologous single-locus mechanisms that arose in the common ancestor of each genus, respectively. (Bottom left) Simplified schematic of a putative functional regulatory element at the Juglans locus. (Bottom right) Strong genotypic correlations across the Carya locus indicate a lack of recombination between two colinear haplotypes with similar gene content.
