Abstract

The cultivation of jujube (Ziziphus jujuba) in China is threatened by jujube witches' broom (JWB) disease, a devastating infectious disease associated with JWB phytoplasma ('Candidatus Phytoplasma ziziphi'). In many plants, proteins in the Argonaute (AGO) family, as main components of the RNA-induced silencing complex (RISC), play important roles in RNA silencing and pathogen resistance. The jujube telomere-to-telomere genome was searched by BLAST using Arabidopsis AGOs as probes. A total of nine jujube AGO gene members were identified, with each containing the conserved N-terminal, PZA, and PIWI domains. Phylogenetic analysis revealed that the nine jujube AGOs scattered into all three Arabidopsis AGO clades. Expression patterns of the ZjAGO genes were analyzed in response to phytoplasma in transcriptome data and by qRT-PCR. The jujube-phytoplasma interaction altered the expression of jujube AGO genes. ZjAGO1 and ZjAGO8 were up-regulated in the majority of the eight sampling periods subjected to qRT-PCR analysis. In the transcriptome data, ZjAGO1 and ZjAGO8 were also up-regulated during the key stages 37 and 39 weeks after grafting (WAG) with phytoplasma-infected material. These two jujube Argonaute genes may play important roles in response to JWB phytoplasma infection.

期刊介绍： Microorganisms (ISSN 2076-2607) is an international, peer-reviewed open access journal which provides an advanced forum for studies related to prokaryotic and eukaryotic microorganisms, viruses and prions. It publishes reviews, research papers and communications. Our aim is to encourage scientists to publish their experimental and theoretical results in as much detail as possible. There is no restriction on the length of the papers. The full experimental details must be provided so that the results can be reproduced. Electronic files and software regarding the full details of the calculation or experimental procedure, if unable to be published in a normal way, can be deposited as supplementary electronic material.
