(A) Origin of <i>clv3-10</i> to <i>clv3-14</i> alleles.

<p>Cyan square (WT): plant with no visible sign of <i>clv3</i> loss-of-function phenotype. Magenta square (KO): plant with full <i>clv3</i> loss-of-function phenotype. Dual-colored squares (pK): plants displaying partial loss-of-function phenotype. RIP: no surviving seedlings. (<b>B-E</b>) Inflorescence of Col-0 wildtype (<b>B</b>), <i>clv3-7</i> (<b>C</b>), a <i>clv3-10</i> T4 plant displaying the full loss-of-function phenotype (<b>D</b>) and a T4 descendant of the pJF752/753 “allele generator” T3 plant displaying a slow onset of the mutant phenotype (<b>E</b>). Green arrowheads: wild-type silique; red arrowheads <i>clv3</i> mutant silique.
