#GA signaling

Gibberellins

GA signaling activates which transcription factor for α-amylase?

GA-MYB (C) is correct here. This is core Gibberellins: once you know the definition or pathway step, GA-MYB is the clear fit. The wrong ones are A) ARF; B) HY5; D) PIF. If the topic is about gradients or potentials, water/solutes move from higher to lower of the relevant quantity.

F-box protein involved in GA signaling in Arabidopsis is:

Go with B — SLY1. Under Gibberellins, this is the standard explanation you’d use in class: it names the real driver or definition, while the rest are nearby but wrong. Not these: A) COI1; C) TIR1; D) AFB. When two options sound similar, choose the one that matches the textbook definition most tightly.

DELLA proteins are degraded via:

Correct option is C, 26S proteasome. In Gibberellins problems like this, the accurate statement is 26S proteasome; the others are common mix-ups. Not these: A) Lysosome; B) Autophagy; D) Vacuole. Tissue transport questions usually turn on xylem vs phloem, living vs dead cells, or source vs sink.

Negative regulator of GA signaling is:

Go with C — DELLA. Under Gibberellins, this is the standard explanation you’d use in class: it names the real driver or definition, while the rest are nearby but wrong. Not these: A) MYB; B) PIF; D) GID1. When two options sound similar, choose the one that matches the textbook definition most tightly.

Gibberellin receptor is:

Answer: B) GID1. For Gibberellins, remember the key idea and you’ll land on this option; the distractors usually swap cause and effect or confuse similar terms. Avoid: A) TIR1; C) ABP1; D) PYL. Name the process first, then pick the option that describes it — don’t reverse cause and effect.
