Q. Ripening mutants in tomato.
- rin, nor, nr
- nir, nor, nr
- ron, rin, nr
A) rin, nor, nr
To achieve full ripening, climacteric fruits, such as tomato require synthesis, perception and signal transduction of the plant hormone ethylene. The nonripening phenotype of the dominant Green-ripe (Gr) and Never-ripe 2 (Nr-2) mutants of tomato is the result of reduced ethylene responsiveness in fruit tissues.
