In order to exploit a fast-growing Paulownia hardwood as an energy crop, xylose-enriched hydrolysate was obtained in this work increase the ethanol concentration using hemicellulosic fraction, besides already widely studied cellulosic fraction. For that, elongata x fortunei submitted autohydrolysis treatment (210 °C or S0 of 4.08) for xylan solubilization, mainly xylooligosaccharides. Afterward...

Phytoplasma is an insect-transmitted pathogen that causes witches' broom disease in many plants. Paulownia witches' broom is one of the most destructive diseases threatening Paulownia production. The molecular mechanisms associated with this disease have been investigated by transcriptome sequencing, but changes in protein abundance have not been investigated with isobaric tags for relative and...

I read with interest the article by Lee et al. entitled " Inhibitory Effect and Mechanism of Antiproliferation of Isoatriplicolide Tiglate (PCAC) from Paulownia Coreana " [1]. This article is quite interesting and the authors should be complimented for the significant amount of work they have done. The purpose of this letter is to call attention to the need for some clarification on the name of...

Paulownia witches’ broom (PaWB) disease caused by phytoplasmas is a fatal disease that leads to considerable economic losses. Long non-coding RNAs (lncRNAs) have been demonstrated to play critical regulatory roles in posttranscriptional and transcriptional regulation. However, lncRNAs and their functional roles remain poorly characterized in Paulownia. To identify lncRNAs and investigate their ...

Paulownia witches' broom (PaWB) caused by phytoplasma might result in devastating damage to the growth and wood production of Paulownia. To study the effect of phytoplasma on DNA sequence and to discover the genes related to PaWB occurrence, DNA polymorphisms and DNA methylation levels and patterns in PaWB seedlings, the ones treated with various concentration of methyl methane sulfonate (MMS) ...

Five geranylflavonoids, one prenylated flavonoid, and a simple flavanone were isolated from an ethanolic extract of Paulownia tomentosa fruit. Tomentodiplacol (1), 3'-O-methyl-5'-methoxydiplacol (2), 6-isopentenyl-3'-O-methyltaxifolin (3), and dihydrotricin (4) are reported from a natural source for the first time and 3'-O-methyldiplacone (6) for the first time from the genus Paulownia. The str...
