Three loci are associated with fragility. In these mutants leaves and stems are easily broken when physically bent. A. Mutant Fragile stem 3 (fst3.c, left) demonstrates the dwarfish of the fst mutants compared to Bowman. B. Small broken pieces of fst2.b. C. Mutant fst1.a obtain an open wound when physical bent, which does not occur in Bowman D
