#jasmonate signalling

7 public questions tagged with this topic.

JAZ proteins inhibit which transcription factor?

Answer: B) MYC2. For Jasmonic acid, remember the key idea and you’ll land on this option; the distractors usually swap cause and effect or confuse similar terms. Avoid: A) ARF; C) NAC; D) WRKY. Name the process first, then pick the option that describes it — don’t reverse cause and effect.

JAZ proteins function as:

Go with C — Repressors of JA signaling. Under Jasmonic acid, 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) Transcription activators; B) Hormone receptors; D) Enzymes. When two options sound similar, choose the one that matches the textbook definition most tightly.

COI1 is a component of which complex?

SCF ubiquitin ligase (B) is correct here. This is core Jasmonic acid: once you know the definition or pathway step, SCF ubiquitin ligase is the clear fit. The wrong ones are A) APC; C) RNA polymerase; D) Proteasome core. If the topic is about gradients or potentials, water/solutes move from higher to lower of the relevant quantity.

Jasmonate receptor protein is:

Correct option is B, COI1. In Jasmonic acid problems like this, the accurate statement is COI1; the others are common mix-ups. Not these: A) TIR1; C) ETR1; D) GID1. Tissue transport questions usually turn on xylem vs phloem, living vs dead cells, or source vs sink.

JAR1 mutants are defective in:

JA-Ile formation (C) is correct here. This is core Jasmonic acid: once you know the definition or pathway step, JA-Ile formation is the clear fit. The wrong ones are A) JA synthesis; B) JA perception; D) Me-JA formation. If the topic is about gradients or potentials, water/solutes move from higher to lower of the relevant quantity.

Which enzyme catalyzes formation of JA-Ile?

Pick D: JAR1. Thinking through Jasmonic acid step by step rules out the lookalikes and leaves JAR1. Skip these: A) LOX; B) AOS; C) AOC. For hormones and genes, match the molecule or gene to its real role, not a neighboring pathway.

Bioactive jasmonate signaling molecule is:

The right choice is C: JA-Ile. In Jasmonic acid, that matches how the process or concept actually works — the other choices mix up related ideas or use the wrong mechanism. Skip these: A) JA; B) Me-JA; D) cis-jasmone. A quick check: if an option needs energy, pumps, or the opposite direction of movement, ask whether that really applies.
