AtMIKC* complexes are essential for pollen germination in vitro. A, Overview of the different Arabidopsis genotypes used for in vitro pollen germination assays, and the AtMIKC* complexes present (white), strongly reduced (light gray), and absent (dark gray) in each of these mutants. B, In vitro pollen germination efficiency for various Arabidopsis genotypes lacking different combinations of AtMIKC* complexes. Asterisks indicate a statistically significant decrease in germination efficiency relative to wild-type (Wt) pollen, as found in a t test, for α = 0.001.
