#strigolactone

6 public questions tagged with this topic.

Strigolactones primarily suppress:

Pick C: Shoot branching. Thinking through Striglactone step by step rules out the lookalikes and leaves Shoot branching. Skip these: A) Root elongation; B) Leaf senescence; D) Seed germination. For hormones and genes, match the molecule or gene to its real role, not a neighboring pathway.

Strigolactone signaling proceeds via:

Answer: C) 26S proteasome pathway. For Striglactone, remember the key idea and you’ll land on this option; the distractors usually swap cause and effect or confuse similar terms. Avoid: A) MAPK pathway; B) cAMP pathway; D) Calcium signaling. Name the process first, then pick the option that describes it — don’t reverse cause and effect.

F-box protein involved in strigolactone signaling is:

Go with C — MAX2. Under Striglactone, 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; B) TIR1; D) GID2. When two options sound similar, choose the one that matches the textbook definition most tightly.

Strigolactone signaling involves degradation of:

Pick C: SMXL proteins. Thinking through Striglactone step by step rules out the lookalikes and leaves SMXL proteins. Skip these: A) JAZ proteins; B) AUX/IAA proteins; D) DELLA proteins. For hormones and genes, match the molecule or gene to its real role, not a neighboring pathway.

The receptor for strigolactones is:

That points to B: D14. Compared with the other options, D14 is the one that correctly describes the Striglactone concept. The wrong ones are A) COI1; C) TIR1; D) ETR1. If you’re stuck, eliminate anything that contradicts a basic fact you already know for this topic.

Transport of strigolactones involves which transporter family?

Correct option is C, ABCG. In Striglactone problems like this, the accurate statement is ABCG; the others are common mix-ups. Not these: A) PIN; B) ABCB; D) AUX1. Tissue transport questions usually turn on xylem vs phloem, living vs dead cells, or source vs sink.
