Table 2.
Upregulation of specific plant physiological processes and gene expression in different methyl jasmonate (MeJA) treatments (M1, M2, and M3) and corresponding developmental stages (F, LG, RR) of strawberry (Fragaria × ananassa ‘Camarosa’) regarding control (C) treatment both in 0 and 48 hpi. F: flowering; LG: large green fruit; RR: 100% red ripe fruit. For experimental details, see the Materials and Methods section.
