AnswerC.
Chilli
D.
Peas
Answer: Option B
Solution
Answer: Option B
Solution:
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.
