Carica papaya plants develop the papaya sticky disease (PSD) as a result of the combined infection of papaya meleira virus (PMeV) and papaya meleira virus 2 (PMeV2), or PMeV complex. PSD symptoms appear only after C. papaya flowers. To understand the mechanisms involved in this phenomenon, the global gene expression patterns of PMeV complex-infected C. papaya at pre-and post-flowering stages were assessed by RNA-Seq. The result was 633 and 88 differentially expressed genes at pre- and post-flowering stages, respectively. At pre-flowering stage, genes related to stress and transport were up-regulated while metabolism-related genes were down-regulated. It was observed that induction of several salicylic acid (SA)-activated genes, including PR1, PR2, PR5, WRKY transcription factors, ROS and callose genes, suggesting SA signaling involvement in the delayed symptoms. In fact, pre-flowering C. papaya treated with exogenous SA showed a tendency to decrease the PMeV and PMeV2 loads when compared to control plants. However, pre-flowering C. papaya also accumulated transcripts encoding a NPR1-inhibitor (NPR1-I/NIM1-I) candidate, genes coding for UDP-glucosyltransferases (UGTs) and several genes involved with ethylene pathway, known to be negative regulators of SA signaling. At post-flowering, when PSD symptoms appeared, the down-regulation of PR-1 encoding gene and the induction of BSMT1 and JA metabolism-related genes were observed. Hence, SA signaling likely operates at the pre-flowering stage of PMeV complex-infected C. papaya inhibiting the development of PSD symptoms, but the induction of its negative regulators prevents the full-scale and long-lasting tolerance.

Schinus terebinthifolia Raddi is a plant used in folk medicine in the treatment of various diseases and has several biological potentials. Its fruit is used as condiment and has high demand in the spice market. In the present study extracts of different polarities prepared from residues from the Brazilian pepper tree processing industry were characterized chemically by gas chromatography/mass spectrometry (GC?MS) and negative-ion mode electrospray ionization Fourier transform ion cyclotron resonance mass spectrometry (ESI(-)FT-ICR MS). The antibacterial activity of the extracts was evaluated against multidrug-resistant strains of hospital origin (Staphylococcus aureus, Enterococcus faecium, Enterococcus faecalis, Pseudomonas aeruginosa and Acinetobacter baumannii) and standard strains (ATCC). The apolar fractions (dichloromethane and hexane) presented triterpenes as main components and the polar extracts (methanol and hydroethanolic extracts) were characterized by high contents of phenolic compounds, especially gallotannins, gallic acid and flavonoids. The methanolic fraction and the hydroethanolic extract of the residues were the most active mainly against S. aureus (MIC 0.60?0.90?mg/mL), E. faecium and E. faecalis (MIC 1.20?2.10?mg/mL). These results demonstrate the richness of bioactive compounds present in the residues and indicate a possible application of this material for the development of biotechnological products with potential against multidrug-resistant bacteria. |
