| dc.description.abstract | Citrus tristeza virus (CTV) is a virus that already caused great losses in citrus producing regions. The cell wall of plant cells plays an important role in the defence response to viruses. Following several studies indicating that cell wall enzyme transcripts of callose synthase 7 (calS7) and xyloglucan endotransglucosylase 9 (xth9) are modified during a viral infection, transcript expression of calS7 isoform x5 (calS7x5) and xth9 was evaluated over time in Citrus x sinensis 'Valencia Late' (VL) and Citrus x clementina 'Fina' (CL), infected with the severe CTV isolate T318A, by quantitative (q) PCR. qPCR analysis of healthy and CTV infected citrus was performed at 15 days, 10 months and at 31 months post-inoculation (dpi/mpi), respectively. The CTV titer, evaluated at the three time-points by qPCR, increased over time in bark tissues, with VL plants exhibiting a titer about 5 times higher than CL 31 mpi. CTV infection did not cause significant changes in calS7x5 gene expression over time in both citrus cultivars. However, CTV infection was associated with significant up-regulation of xth9 in VL compared to controls 31 mpi. This study highlights that CTV infection can affect the expression of specific cell wall-associated genes over time and that this influence was distinct for VL and CL. This study provides further insight into the CTV-citrus host interaction, with the long-term response of VL to a severe CTV isolate involving a high expression of the xth9 gene. | pt_PT |
