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.
