In the current study, the expression characteristics and evolution of <i>PsmiR319</i> in tree peony flowering was explored using 'Feng Dan' and 'Lian He', which are early-flowering and late-flowering varieties of tree peony, respectively. The structure, evolution, and target(s) of <i>PsmiR319</i> were analyzed by bioinformatics. Evolution analysis showed that pre-<i>PsmiR319</i> was distributed in 41 plant species, among which the length of the precursor sequence exhibited marked differences (between 52 and 308 bp). Pre-<i>PsmiR319</i> of tree peony was located close to the corresponding sequences of <i>Linum usitatissimum</i> and <i>Picea abies</i> in the phylogenetic tree, and in addition, could form a typical hairpin structure including a mature body with a length of 20 bp located on the 3p arm and part of the loop sequence. The mature sequence of miR319 was highly conserved among different species. Target genes of <i>PsmiR319</i> include MYB-related transcription factor in tree peony. Expression of <i>PsmiR319</i>, assayed by qRT-PCR, differed between 'Feng Dan' and 'Lian He' during different flower development periods. <i>PsmiR319</i> and its target gene showed a negative expression regulation relationship during the periods of CE (color exposure), BS (blooming stage), IF (initial flowering), and HO (half opening) in the early-flowering 'Feng Dan', and the same in FB (Full blooming) periods of late-flowering 'Lian He'.

Recent findings indicate that the Arabidopsis thaliana GCN2 protein operates under the command of reactive oxygen species (ROS) emanating from the chloroplast under a variety of abiotic stresses such as excess light. To get deeper insights into the mechanism of GCN2 activation under excess light, we assessed the role of amino acids in view of the classic function of GCN2 as a sensor of amino acid status.
