Exogenous jasmonic acid signaling in Brassica napus increases JA content but reduces nectar volume, flower size, and volatile emissions, linked to less honeybee visitation.
- Why it matters: Jasmonic acid is a key regulator of plant responses and can reshape plant–pollinator interactions by altering floral development, nectar, and volatile organic compounds.
- What they did: Brassica napus plants received exogenous JA at 0.5 mM, 1.0 mM, or 2.0 mM, compared with herbivore feeding and mechanical damage, then floral traits, nectar composition, volatiles, and honeybee behavior were measured.
- The result: Honeybees visited less frequently and spent less time on herbivory-damaged and JA-induced plants, with lower landing success and revisitation rates, and these changes were associated with reduced reproductive outcome.
