↵a Plants in this phenotypic class had slightly yellowed leaves and microscopic cell death and were of medium stature.
↵b b Plants in this phenotypic class had many visible punctate cell death patches and were of reduced stature.
↵c The hypothesis is that acd6 segregates as a semidominant trait with respect to cell death.
↵d M2 designates the original mutant plant.
↵e Not significantly different from the expected value (P > 0.7 to 0.9 in each of these cases).
↵f This is the progeny of a mild cell death and medium stature F1 plant.
↵g This is the progeny of a healthy, normal stature F1 plant.
↵h CS3432 is a gi-2 co-1 tetraploid Arabidopsis in the Col-0 background (acd6 is from the same background).
