Project description:In this study we used vascular specific promoters and a translating ribosome affinity purification strategy to identify phloem-associated translatome responses to infection by tobacco mosaic virus (TMV) in the systemic host Nicotiana benthamiana. Three different promoter:FLAG-RPL18 lines were used. These included two phloem specific promoters (pSUC2 and pSULTR2;2) as well as the more ubiquitously expressed cauliflower mosaic virus 35S promoter (p35S). Immunopurification of ribosome-mRNA complexes was accomplished by the method described in Reynoso et al. (Plant Functional Genomics: Methods and Protocols, 185-207; 2015). The dataset includes samples from the leaves of 5-week-old plants inoculated with TMV (1 mg/mL) or mock inoculated with sterile water.

Project description:A silencing signal in plants with an RNA specificity determinant moves through plasmodesmata and the phloem. To identify the mobile RNA we grafted Arabidopsis thaliana shoots to roots that would be a recipient for the silencing signal. Using high throughput sequencing as a sensitive detection method and mutants to block small RNA (sRNA) biogenesis in either source or recipient tissue, we detected endogenous and transgene specific sRNA that moved across the graft union. Surprisingly we found that the mobile endogenous sRNAs account for a substantial proportion of the sRNA in roots and we provide evidence that 24nt mobile sRNAs direct epigenetic modifications in the genome of the recipient cells. Mobile sRNA thus represents a mechanism for transmitting the specification of epigenetic modification and could affect genome defence and responses to external stimuli that have persistent effects in plants.

Project description:In this study we used a translating ribosome affinity purification strategy to identify phloem and non-phloem associated translatomes in Prunus domesitca L during PPV infection. Three different promoter:His6FLAG-RPL18 lines were used. These included two phloem specific promoters (pSUC2 and pSULTR2;2) as well as the more ubiquitously expressed cauliflower mosaic virus 35S promoter (p35S). Immunopurification of ribosome-mRNA complexes was accomplished by the method described in Reynoso et al. (Plant Functional Genomics: Methods and Protocols, 185-207; 2015). The dataset includes samples from plum leaves taken at 2, 4, 6, and 12 weeks post cold induced dormancy.

Project description:Transformation of undifferentiated stem cells into cells with special functions is central for organismal development. The phloem tissue mediates long-distance transport of energy metabolites along plant bodies and is characterized by an exceptional degree of cellular specialization. How the phloem-specific developmental program is implemented is, however, unknown. Here we reveal that the ubiquitously expressed PHD-finger protein OBERON3 (OBE3) and the phloem-specific SUPPRESSOR OF MAX2 1-LIKE 5 (SMXL5) protein form a central module for establishing phloem identity in Arabidopsis thaliana (Arabidopsis). By phloem-specific ATAC-seq analyses, we show that OBE3 and SMXL5 proteins establish a phloem-specific chromatin profile.

Project description:In order to find the miRNAs, target genes and signaling pathways related to the dwarf phenotype induced by NlCSP1, 35S-NlCSP1 and 35S-GFP control were infiltrated into Nicotiana benthamiana. We analyzed the differentially expressed miRNAs in the infiltrated leaves (NlCSP1_Z/GFP_Z) and the upper uninfiltrated leaves (NlCSP1_O/GFP_O) of N. benthamiana. A total of 106 and 97 differentially expressed miRNAs were identified in NlCSP1_Z/GFP_Z and NlCSP1_O/GFP_O, respectively. KEGG annotation revealed a large number of differentially expressed miRNAs involved in plant hormone signal transduction, indicating that NlCSP1 changed the hormone signal pathway in N. benthamiana.
