So this paper was using mutagenic herbicides on a plant - the type that dissolve the spindle fibers and cause ploidy mutations, and a rather high percentage of the embryos derived from leaf explants after said treatment had cotyledon mutations, including having four cotyledons.
Ploidy mutants can arise naturally. I was torture testing some sativas, with a grow room at 140F at times and never dropping to any reasonable temperature, and crossed a sativa from Jamaica (Columbian?) with an African plant. The resulting seeds were so extremely mutated, they seemed super sized. I never tested to prove the reason, but it seems highly likely to me that the high temps also damaged the spindle. I wonder if the seeds are still viable, it’s been a decade or so.
