You have discovered a new growth regulator, designated Tamvin (TV), that affects flowering. You also identify four TV mutations, three recessive (R) and one dominant (D), that all affect the TV signaling pathway controlling flowering. The number of flowers produced by plants with the indicated genotypes that are grown in the presence and absence of TV are shown in the table. You also find that the GRN gene product binds TV and the BLU gene encodes a transcription factor that activates the next downstream gene in the pathway. Q7.2 40000 Points (i) State which components of the pathways are positive and negative regulators of flowering, and (ii) indicate how the components interact with each other in the pathway in the presence and absence of TV. Use the symbols --> for activation and the symbol --] for repression of the immediately downstream gene or protein in the pathway. Briefly explain your answers..
