Given some statements about the roles of phytochrome and gibberellin in shade avoidance response;

A) In direct sunlight, red light predominates and the Pfr form of phytochrome moves into the nucleus.

B) Under a plant canopy, the light is enriched in far-red wavelengths. Phytochrome is in the inactive Pr form.

C) As PIF proteins accumulate, PIF-induced gene expression increases, promoting stem elongation.

D) Phy causes the turnover of PIF proteins, which act as negative regulators of  photomorphogenesis

E) In the absence of Pfr, PIFs are not degraded, the sensitivity to gibberellin increases, causing the degradation of DELLA repressors

F) As a result, DELLA repressors bind PIF and prevent the transcription of PIF-regulated gene, In the absence of PIF-induced gene expression, stem growth is limited.

Find out the correct sequence of these responses.
