Project description:Grafting is an ancient cloning method that has been used widely for thousands of years in agricultural practices. However, the molecular mechanisms for graft union development are still largely unknown. The developmental stage of graft union was characterized based on micrografting method. Microarray data revealed a signal exchange process between cells of scion and stock at 1dag, which reestablished the communication network in graft union. This process was concomitant with the cleaning of cell debris, and both of the processes were initiated by a wound-induced program. The results demonstrate the feasibility and potential power of investigating various plant developmental processes by this method and represent a primary and significant step in interpretation of the molecular mechanisms underlying graft union development. WT/WT seedling grafts of 22-26 hours after grafting were collected for microarray, intact WT seedlings and ungrafted scions and stocks were as control. All three types of sample, grafts (marked as A: whole graft), ungrafted scions and stocks (marked as B: mixture of ungrafted scions and stocks) and intact seedlings (marked as C: whole seedling), were collected at the same time of 22-26 hours after grafting. For sample B, scions and stocks were cut at the same time during grafting. For sample C, intact seedlings were also reserved during grafting. Data were firstly compared between sample A and C, differential expressed probe sets were than tested based on A and B to obtain graft-specific probes.

Project description:Grafting was widely used in pear cultivation as an ancient cultivation technique, the use of rootstocks could improve the resistance of pear trees, make pear trees early fruit. The healing process of plant grafting involves complex signal transduction and material accumulation.We used two different grafting combinations, include ‘Qingzhen D1’ on ‘QAUP-1’ and ‘Qingzhen D1’ on ‘Qingzhen D1’.The samples which are the part of graft union of those two combinations were collected om 1 day, 5 days , 9 days and 30 days after grafting. We performed an in-depth RNA-seq analysis to observe the transcriptional changes that occur during the development of two combinations.

Project description:Hickory (Carya cathayensis) is a woody plant with high nutritional and economic value, and is widely cultivated in China. It is different from herbaceous plants and undergoes a long vegetative stage before reaching floral transition. Hickory can be cultivated on a large scale using grafting. To reveal the response mechanisms to grafting, we employed a proteomics-based approach to identify differentially expressed proteins during the hickory grafting process. In our study, 3723 proteins were identified and 2518 proteins were quantified. A total of 710 differentially quantified proteins (DQPs) were identified and these were involved in various molecular functional and biological processes. Among these DQPs, 341 were up-regulated and 369 were down-regulated at 7 days after grafting compared to the control. The protein interaction networks of the DQPs indicated that there were two enriched interaction clusters. These were „ribosome‟ and „starch and sucrose metabolism‟. Four auxin-related proteins were down-regulated, which was in agreement with the transcription levels of their encoding genes. The Kyoto Encyclopedia of Genes and Genomes analysis showed that the „Flavonoid biosynthesis‟ pathway was significantly up-regulated. Further experiments verified a significant increase in the total flavonoid contents in scions, which suggested that graft union formation may activate flavonoid biosynthesis to increase the contents of a series of downstream secondary metabolites. This comprehensive analysis provides fundamental information on the candidate proteins and the secondary metabolism pathways involved in the grafting process for hickory.

Project description:The widespread use of plant grafting has enabled different plants to join and combine their best properties to improve stress tolerance, growth and yields. Grafting is commonly performed between closely related eudicots or gymnosperms where mechanisms permit tissue fusion yet limit success as plants become unrelated. To investigate these aspects, we developed a micrografting method using young conifer tree seedlings that enabled divergent conifer members to successfully graft. Conifer grafts showed rapid connection of phloem and xylem at the junction, while a genome-wide transcriptome analysis of the Picea abies (Norway spruce) healing junction revealed differential expression of thousands of genes including those related to auxin response and cell wall biogenesis. We compared these genes to those induced during Arabidopsis thaliana graft healing and found a common activation of cambium, cell division, phloem and xylem-related genes. A gene regulatory network analysis revealed that PHYTOCHROME A SIGNAL TRANSDUCTION 1 (PAT1) acted as a central hub during Picea grafting and was also induced during Arabidopsis grafting. Arabidopsis mutants lacking PATs failed to attach tissues or successfully graft, while complementing Arabidopsis PAT mutants with the Picea abies PAT1 homolog could rescue tissue attachment and enhance callus formation. Together, our data demonstrate a competency for young tissues to graft to distantly related species and identifies the PAT gene family as conserved regulators of graft healing and tissue regeneration in eudicots and gymnosperms.

Project description:To further development of our gene expression approach to cardiovascular disease, we have employed microarray expression profiling as a discovery platform to identify genes with the potential to distinguish the therapeutic target of the vein graft restenosis following coronary artery bypass grafting. Vein graft samples were obtained from model rats which received external jugular vein-carotid bypass grafting at different postoperative timepoints (n=3/group; day 7, 14 and 28, respectively). Vein samples were also obtained from control rats without vascular grafting (n=3/group; day 0). Time-dependent gene expression profiles were described with microarray analysis. Expression of three lncRNA-mRNA pairs (AF062402-Src, BC091437-Edg1 and BC166461- Mcam) from this signature were quantified in the same RNA samples by real-time PCR, confirming the accuracy of the microarray data.
