| Bioactivity | Jarin-1 is a jasmonic acid-amido synthetase (JAR1) inhibitor with an IC50 of 3.8 μM. Jarin-1 specific inhibits bioactive JA (jasmonoyl-isoleucine, JA-Ile) biosynthesis in Arabidopsis and other plants[1][2]. | |||||||||
| Target | Jasmonic acid-amido synthetase (JAR1) | |||||||||
| Invitro | A higher redness of strawberry fruit skin and anthocyanin content in MeJA-treated fruits with respect to Jarin-1-treated ones concomitant with an upregulation of FaANS and FaUFGT genes is found. Inversely, the proanthocyanidin (PA) content was higher in Jarin-1- and MeJA + Jarin-1-treated than in MeJA-treated fruits. MeJA + Jarin-1 treatment resulted in an upregulation of FaANR and associated transcription factors such as FabHLH33 and FaMYB9/11 along with FaJMT and FaJAR1.2. JA-responsive elements in the promoter regions of FaMYB1/9/10/11 genes is found. PA biosynthesis-related genes can be upregulated by the application of Jarin-1 to MeJA-treated fruit, thus increasing PA accumulation in strawberry[1]. | |||||||||
