Characterization of PsmiR319 during flower development in early- and late-flowering tree peonies cultivars.

ABSTRACT: The flowering period is the most important ornamental trait of tree peony, while industrial development of tree peony has been limited by short flowering period. miR319 plays an important regulatory role in plant flowering. In the current study, the expression characteristics and evolution of PsmiR319 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 PsmiR319 were analyzed by bioinformatics. Evolution analysis showed that pre-PsmiR319 was distributed in 41 plant species, among which the length of the precursor sequence exhibited marked differences (between 52 and 308 bp). Pre-PsmiR319 of tree peony was located close to
