Jasmonic acid

Jasmonic acid

Exogenous JA application generally causes:

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

JA is involved in senescence mainly of:

Go with C — Flowers more than leaves. 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) Roots; B) Leaves only; D) Seeds. When two options sound similar, choose the one that matches the textbook definition most tightly.

JA deficient mutants show:

Answer: C) High susceptibility to insects. 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) Increased resistance to insects; B) Normal defense; D) Early flowering. Name the process first, then pick the option that describes it — don’t reverse cause and effect.

JA accumulation increases in response to:

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

JA-induced growth suppression helps in:

Defense resource allocation (B) is correct here. This is core Jasmonic acid: once you know the definition or pathway step, Defense resource allocation is the clear fit. The wrong ones are A) Cell elongation; C) Photosynthesis increase; D) Seed dormancy. If the topic is about gradients or potentials, water/solutes move from higher to lower of the relevant quantity.

Jasmonic acid

JA conjugation with glucose forms:

C fits best: Jasmonyl-1-β-glucose. Keep the Jasmonic acid basics straight and Jasmonyl-1-β-glucose stands out as the precise answer. Avoid: A) JA-Ile; B) Me-JA; D) cis-jasmone. Light and flowering items often hinge on which photoreceptor or day-length rule is in play.

Jasmonic acid

Tuberonic acid is chemically:

The right choice is A: 12-hydroxy jasmonic acid. 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: B) Methyl jasmonate; C) cis-jasmone; D) JA-Ile. A quick check: if an option needs energy, pumps, or the opposite direction of movement, ask whether that really applies.

Jasmonic acid

cis-jasmone is produced by:

The right choice is C: Decarboxylation of JA. 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) Hydroxylation; B) Methylation; D) Glycosylation. A quick check: if an option needs energy, pumps, or the opposite direction of movement, ask whether that really applies.

GLABRA2 acts:

B fits best: Downstream of GL1–GL3–TTG1. Keep the Jasmonic acid basics straight and Downstream of GL1–GL3–TTG1 stands out as the precise answer. Avoid: A) Upstream of GL1; C) As JA receptor; D) As JAZ protein. Light and flowering items often hinge on which photoreceptor or day-length rule is in play.

TRY gene functions as:

The right choice is B: Negative regulator of trichomes. 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) Positive regulator of trichomes; C) JA receptor; D) JA enzyme. A quick check: if an option needs energy, pumps, or the opposite direction of movement, ask whether that really applies.

GL1, GL3, and TTG1 together form:

That points to B: Activation complex. Compared with the other options, Activation complex is the one that correctly describes the Jasmonic acid concept. The wrong ones are A) Repressor complex; C) SCF complex; D) MAPK complex. If you’re stuck, eliminate anything that contradicts a basic fact you already know for this topic.

JA-induced trichome formation occurs in:

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