Tomato and Cotton (IMAGE) Cold Spring Harbor Laboratory Caption The tomato self pruning (sp) mutant (right) has a compact 'determinate' growth habit with a burst of flowering and fruit production compared to the continuous 'indeterminate' vine-like growth of classical plants (left). The cotton sp mutant (Gbsp) has determinate shoots that result in the 'clustered boll' trait. The two mutants provide shorter stature with multiple agronomic, or crop production, adaptations.
