#Unit 6. System Physiology – Plant
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.
