Paulownia witches’ broom (PaWB) is a disastrous epidemic disease in Paulownia tomentosa trees in many parts of the world. Infected Paulownia tomentosa trees are generally characterized by witches’ brooms, proliferating branches, yellowing and withering leaves, and branch dieback. In previous studies, we found that by treating seedlings with a certain(More)
Polyploidy events are believed to be responsible for increasing the size of plant organs and enhancing tolerance to environmental stresses. Autotetraploid Paulownia australis plants exhibit superior traits compared with their diploid progenitors. Although some transcriptomics studies have been performed and some relevant genes have been revealed, the(More)
Understanding the role of miRNAs in regulating the molecular mechanisms responsive to drought stress was studied in Paulownia "yuza 1." Two small RNA libraries and two degradome libraries were, respectively, constructed and sequenced in order to detect miRNAs and their target genes associated with drought stress. A total of 107 miRNAs and 42 putative target(More)
Paulownia witches' broom (PaWB) disease caused by phytoplasma is a fatal disease that leads to considerable economic losses. Although there are a few reports describing studies of PaWB pathogenesis, the molecular mechanisms underlying phytoplasma pathogenicity in Paulownia trees remain uncharacterized. In this study, after building a transcriptome database(More)
