Striglactone

Striglactone

Strigolactones belong to which hormone category?

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

Strigolactones are important under which nutrient deficiency?

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

Striglactone

Strigolactones reduce formation of:

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

GR24 treatment can rescue phenotype of:

The right choice is B: SL-deficient mutants. In Striglactone, that matches how the process or concept actually works — the other choices mix up related ideas or use the wrong mechanism. Skip these: A) SL-insensitive mutants; C) Auxin mutants; D) GA mutants. A quick check: if an option needs energy, pumps, or the opposite direction of movement, ask whether that really applies.

Strigolactone-deficient mutants show:

Correct option is C, Excessive branching. In Striglactone problems like this, the accurate statement is Excessive branching; the others are common mix-ups. Not these: A) Reduced branching; B) Normal branching; D) No roots. Tissue transport questions usually turn on xylem vs phloem, living vs dead cells, or source vs sink.

Striglactone

Strigolactones promote symbiosis with:

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

Striglactone

Cytokinin generally acts as a:

Pick B: Antagonist of SL. Thinking through Striglactone step by step rules out the lookalikes and leaves Antagonist of SL. Skip these: A) Synergist of SL; C) Precursor of SL; D) Receptor of SL. For hormones and genes, match the molecule or gene to its real role, not a neighboring pathway.

Striglactone

Auxin influences strigolactone action by:

The right choice is B: Stimulating SL synthesis. In Striglactone, that matches how the process or concept actually works — the other choices mix up related ideas or use the wrong mechanism. Skip these: A) Inhibiting SL synthesis; C) Blocking SL transport; D) Degrading SLs. A quick check: if an option needs energy, pumps, or the opposite direction of movement, ask whether that really applies.

BRC1 gene activated by strigolactones encodes:

Pick C: Transcription factor. Thinking through Striglactone step by step rules out the lookalikes and leaves Transcription factor. Skip these: A) Receptor; B) Enzyme; D) Transporter. For hormones and genes, match the molecule or gene to its real role, not a neighboring pathway.

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.

Striglactone

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.
