Coronatine
Based on 1 Customer Validation
Coronatine is a plant growth regulator that mimicks the jasmonic acid-isoleucine conjugate (JA-Ile), targets the jasmonic acid receptor COI1, activates the jasmonic acid signaling pathway, thereby inhibiting salicylic acid (SA)-dependent defense responses. Coronatine antagonizes the stomatal closure, induces plant cell necrosis and chlorosis, interfers with plant hormone balance, thereby promoting pathogen infection.

Biological Activity
Coronatine (1 μM, 24 h) induces the expression of NAC transcription factor genes (ANAC019, ANAC055 and ANAC072), inhibits Abscisic acid (HY-100560)-induced stomatal closure and reopen stomata, inhibits the accumulation of Salicylic acid (HY-B0167), thereby weakening the plant's immune response[3].

Select the appropriate dissolution method based on your experimental animal and administration route.
- For the following dissolution methods, please ensure to first prepare a clear stock solution using an In Vitro approach and then sequentially add co-solvents:
- To ensure reliable experimental results, the clarified stock solution can be appropriately stored based on storage conditions. As for the working solution for In Vivo experiments, it is recommended to prepare freshly and use it on the same day.
- The percentages shown for the solvents indicate their volumetric ratio in the final prepared solution. If precipitation or phase separation occurs during preparation, heat and/or sonication can be used to aid dissolution.
