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.

Phytopathogens represent a major threat to crop productivity. In the case of citrus, in particular Citrus aurantifolia (Christm.) Swingle, a major pathogen is ‘Candidatus Phytoplasma citri’, the causative agent of Witches’ broom disease of lime (WBDL). Although the taxonomy of this pathogen is established, molecular aspects of the disease it causes and its genetic variability have received little attention. Here, we use a draft genome to obtain insights into genomic features and pathogenicity factors of this phytoplasma. We also provide new information about genetic variability within ‘Ca. P. citri’ populations in Oman, a country that has been greatly affected by WBDL. Comparative analyses with other phytoplasma species show that the vast majority of protein coding genes, including the secretome, are shared between the WBDL phytoplasmas and ‘Ca. P. asteris’ strain AY-WB. A multi-locus sequence typing analysis in ‘Ca. P. citri’ strain populations from plants and insect vectors revealed substantial genetic homogeneity among ‘Ca. P. citri’ populations, suggesting a recent clonal replication of a phytoplasma strain in Oman. Our data add taxon sampling to genomic studies of phytoplasmas, as well as offering insights into the genetic variability of ‘Ca. P. citri’ populations of plant and insect hosts from different locations in Oman. |
