Paulownia is a native fast-growing tree in China that has been introduced into many countries. However, it is often infected by Paulownia witches' broom (PaWB) disease, which can lead to large declines in yield. PaWB is caused by a phytoplasma that is an obligate biotrophic plant pathogen. Until now, the molecular mechanisms of interactions between the host plants and the phytoplasma have not been clear. In previous studies, it was reported that PaWB-infected Paulownia exhibited healthy morphology after being treated with methyl methane sulfonate (MMS) at the concentration of 20 mg·L −1 (for Paulownia tomentosa (PT) and Paulownia fortunei (PF) or 15 mg·L −1 (for P. tomentosa × P. fortunei) MMS. In this study, the whole transcriptome expression profile of PaWB-infected Paulownia was studied using high-throughput sequencing technology. In total, 74 significantly differentially expressed genes were detected among three species of healthy, PaWB-infected Paulownia, and the Paulownia treated with MMS. We identified and analyzed genes related to the roles of phytohormones and alternative splicing events involved in regulating plant growth. In response to phytoplasma infection, the concentrations of the plants' phytohormones were altered, leading to morphology transformation. This research will provide valuable information to detect the molecular mechanisms involved in the Paulownia response to phytoplasma infection.

“…This increase may be due to osmotic adjustment. These compatible solutes enhance the tolerance of plants and increasing their adaptation to severe stresses (Fahad et al, 2015). Proline has also been considered as a carbon and nitrogen source for rapid recovery from stress, a stabilizer for membranes and some macromolecules, a free radical scavenger (Jain et al, 2002) and a protective agent for cytosolic enzymes and cellular organelles (Yazici et al, 2007).…”

T HE PRESENT study was carried out to investigate the effect of high NaCl concentrations on some growth parameters and physiological processes of wheat (Triticum aestivum L.) plant. The results indicated that Gemeza.9 was the most sensitive cultivar to high salinity levels compared to all tested wheat cultivars. Moreover, salinity stress caused a reduction in the germination percentage by 65% and all growth parameters by 21%, 25% and 60% in the lengths of shoot, root and leaf area, also by 27% and 48% in fresh weights of shoot, root and 40% and 75% in dry weights of shoot and root. It also increased the activity of antioxidant enzymes (peroxidase and catalase), lipid peroxidation and ascorbic acid content. Salinity induced increase of osmolytes compounds such as total soluble proteins, carbohydrates and amino acids. Furthermore, all measured yield parameters, the percentage of grain's maturity and productivity were highly decreased. Accordingly, the role of potassium humate and potassium silicate either sole or combined in alleviating the toxic effect of salinity was also studied. Results showed that application of potassium humate as sole had a stimulatory effect higher than potassium silicate or their combination. It increased the germinating percentage by 128% at 200mM NaCl. In addition, potassium humate and potassium silicate increased the photosynthetic activity, decreased the activity antioxidant enzymes (Peroxidase and Catalase) as well as biosynthesis of MDA and ascorbic acid also they induced increase biosynthesis of proteins and carbohydrates in yielded grains. Accordingly, our study recommends the application of potassium humate as an organic fertilizer and potassium silicate as a foliar spray for improving the quality and quantity of the sensitive wheat cultivar Gemeza.9 cultivated in salty lands and increases its productivity.

“…Auxin, cytokinins (CKs), gibberellins (GAs) and brassinosteroids (BRs) are defined as "positive growth regulators", and abscisic acid (ABA), jasmonic acid (JA), salicylic acid (SA) and ethylene are counted as "stress hormones" (Kovosá et al, 2012). These phytohormones are thought to be the most important signal substances in modulating physiological responses for stress adaptation, such as growth, development, source/ sink transitions and nutrient allocation (Fahad et al, 2014). Therefore, they were important for understanding AM functions on drought tolerance of the host plant.…”
