| Popis: | Molecular mechanisms underlying phytoplasma interactions with host plants are largely unknown. In this study attempts were made to identify effectors of three phytoplasma strains related to 'Ca. P. aurantifolia', crotalaria phyllody (CrP), faba bean phyllody (FBP), and witches' broom disease of lime (WBDL), using information from draft genome of peanut witches' broom phytoplasma. Seven putative effectors were identified in WBDL genome (SAP11, SAP21, Eff64, Eff115, Eff197, Eff211 and EffSAP67), five (SAP11, SAP21, Eff64, Eff99 and Eff197) in CrP and two (SAP11, Eff64) in FBP. No homologs to Eff64, Eff197 and Eff211 in phytoplasmas of other phylogenetic groups were found. SAP11 and Eff64 homologs of 'Ca. P. aurantifolia' strains shared at least 95.9% identity and were detected in the three phytoplasmas, supporting their role within the group. Five of the putative effectors (SAP11, SAP21, Eff64, Eff115, and Eff99) were transcribed from total RNA extracts of periwinkle plants infected with these phytoplasmas. Transcription profiles of selected putative effectors of CrP, FBP and WBDL indicated that SAP11 transcripts were the most abundant in the three phytoplasmas. SAP21 transcript levels were comparable to those of SAP11 for CrP and not measurable for the other phytoplasmas. Eff64 had the lowest transcription level irrespective of sampling date and phytoplasma isolate. Eff115 transcript levels were the highest in WBDL infected plants. This work reports the first sequence information for 14 putative effectors in three strains related to 'Ca. P. aurantifolia', and offers novel insight into the transcription profile of five of them during infection of periwinkle. |
