New Insight into the Related Candidate Genes and Molecular Regulatory Mechanisms of Waterlogging Tolerance in Tree Peony Paeonia ostii.

ABSTRACT: Research on the waterlogging tolerance mechanisms of Paeonia ostii helps us to further understand these mechanisms in the root system and enhance its root bark and oil yields in southern China. In this study, root morphological identification, the statistics of nine physiological and biochemical indicators, and a comparative transcriptome analysis were used to investigate the waterlogging tolerance mechanism in this plant. As flooding continued, the roots' vigor dramatically declined from 6 to 168 h of waterlogging, the root number was extremely reduced by up to 95%, and the number of roots was not restored after 96 h of recovery. Seven of the nine physiological indicators, including leaf transpiration and photosynthetic rate, stomatal conductance, root activity, and soluble protein
