Ripening mutants rin, nor, Nr are found in which crop?

Answer & Solution
Correct Answer: Option B
Ripening mutants rin, nor, CNr is found in Tomato.
Tomato fruit ripening is regulated by transcription factors (TFs), their downstream effector genes, and the ethylene biosynthesis and signaling pathway. Spontaneous non-ripening mutants ripening inhibitor (rin), non-ripening (nor), and Colorless non-ripening (Cnr) correspond with mutations in or near the TF-encoding genes MADS-RIN, NAC-NOR and SPL-CNR, respectively.
