Project description:Citrus and most other fruit crops are commercially propagated via grafting, which ensures trees have consistent fruit traits combined with favorable traits from the rootstock such as soil adaptability, vigor, and resistance to soil pathogens. Breeding new rootstocks requires careful agronomic evaluations, and widespread use of new rootstocks and scions requires graft compatibility with commercially important scions and rootstocks. Graft incompatibility can occur when the scion and rootstock are not able to form a permanent, healthy union. Understanding and preventing graft incompatibility is therefore of paramount importance in the breeding of new fruit cultivars and in the choice of scion and rootstock by growers. The rootstock US-1283 is a citrandarin generated from a cross of ‘Ninkat’ mandarin (Citrus reticulata) and ‘Gotha Road’ #6 trifoliate orange (Poncirus trifoliata). It was released in 2014 after years of field evaluation because of its superior productivity and good fruit quality on ‘Hamlin’ sweet orange (C. sinensis) under Florida’s growing conditions. Subsequently, it was observed that trees of ‘Bearss’ lemon (C. limon) and ‘Valencia’ sweet orange (C. sinensis) grafted onto US-1283 exhibited apparent incompatible and unhealthy growth near the graft union. The incompatibility manifested as stem grooving and necrosis underneath the bark on the rootstock side of the graft. A genetically similar citrandarin rootstock, US-812 (C. reticulata ‘Sunki’ × P. trifoliata ‘Benecke’), is fully graft compatible with the same scions. Transcriptome analysis was performed on the vascular tissues above and below the graft union of compatible US-812 and incompatible US-1283 graft combinations with ‘Bearss’ and ‘Valencia’ to identify expression networks associated with incompatibility and help understand the processes and potential causes of incompatibility in citrus. Transcriptional reprogramming was stronger in the incompatible rootstock than in the grafted scions. Functional analysis of the transcriptional events below the graft unions of US-1283 incompatible combinations revealed differentially expression genes (DEGs) associated with oxidative stress and plant defense, among other pathways, similar to a pathogen-induced immune response localized to the rootstock, although no known pathogens were detected in the assayed plants. These changes were not observed above the graft unions.Differentially expressed genes (DEGs) in US-1283, but not the scions, were associated with oxidative stress and plant defense, among others, similar to a pathogen-induced immune response localized to the rootstock. No pathogen infection was detected. It is hypothesized this response could have been triggered by signaling miscommunications between rootstock and scion either through 1) unknown molecules from the scion that were perceived as danger signals by the rootstock, 2) missing signals from the scion or missing receptors in the rootstock necessary for the formation of a healthy graft union, 3) the overall perception of the scion by the rootstock as non-self, or 4) a combination of the above.

Project description:Grafting is a well-established practice for grapevine to facilitate propagation of productive and tolerant cultivars against several stress factors. It is also considered to be a suitable method for studying molecular aspects of root-to-shoot and/or shoot-to-root signaling events. So far, controlling only effect of rootstock over scion was investigated and root-to-shoot transcriptomic alterations were fallowed on the scions or graft interfaces. The objective of this study was to investigate transcriptomic and physiological influence of scion on the rootstock under drought stress. Therefore, drought tolerant 110R rootstock were firstly grafted with sultana seedless and tested under drought stress with its non-grafted counterpart. The results of treatment indicated that grafted 110R performed the highest root elongation under drought. We carried out a microarray based transcriptome analysis on the roots of grafted and non-grafted 110R to explain this drought derived interaction through scion-to-rootstock. The highest expression increase under drought was recorded for sugar (SWEET) and nitrate or di/tri-peptide (NRT1/ PTR FAMILY) transporter proteins. Expression level of these genes was more highly increased in grafted 110R than its non-grafted counterpart. This situation indicated their potential role in drought tolerance and scion/rootstock harmony. Overexpression of these transporters attributed to increased amount of released nutrient and nitrogen source from abscised leaves of sultana seedless under drought. Remobilization of these rich sources was suggested to chance transcriptomic response of rootstocks and enabled much better growth in grafted 110R. Other transcripts annotated to cell wall modification enzymes (chitinases), osmoregulator proteins (dehydrins, proline-glycine rich proteins) and secondary metabolites (stilbene synthase) were also more highly induced in grafted 110R. This is the first report indicating transcriptomic influence of scion on the grapevine rootstocks and representing the genes responsible in scion/rootstock harmony and drought tolerance.

Project description:<p><strong>BACKGROUND:</strong> Modern biological approaches generate volumes of multi-dimensional data, offering unprecedented opportunities to address biological questions previously beyond reach owing to small or subtle effects. A fundamental question in plant biology is the extent to which below-ground activity in the root system influences above-ground phenotypes expressed in the shoot system. Grafting, an ancient horticultural practice that fuses the root system of one individual (the rootstock) with the shoot system of a second, genetically distinct individual (the scion), is a powerful experimental system to understand below-ground effects on above-ground phenotypes. Previous studies on grafted grapevines have detected rootstock influence on scion phenotypes including physiology and berry chemistry. However, the extent of the rootstock's influence on leaves, the photosynthetic engines of the vine, and how those effects change over the course of a growing season, are still largely unknown.</p><p><strong>RESULTS:</strong> Here, we investigate associations between rootstock genotype and shoot system phenotypes using 5 multi-dimensional leaf phenotyping modalities measured in a common grafted scion: ionomics, metabolomics, transcriptomics, morphometrics, and physiology. Rootstock influence is ubiquitous but subtle across modalities, with the strongest signature of rootstock observed in the leaf ionome. Moreover, we find that the extent of rootstock influence on scion phenotypes and patterns of phenomic covariation are highly dynamic across the season.</p><p><strong>CONCLUSIONS:</strong> These findings substantially expand previously identified patterns to demonstrate that rootstock influence on scion phenotypes is complex and dynamic and underscore that broad understanding necessitates volumes of multi-dimensional data previously unmet.</p>

Project description:Purpose: Grafting is a commonly used cultural practice to counteract salt stress and is especially important for vegetable production. However, it is not clear which metabolic processes and genes are involved in the response of tomato rootstocks to salt stress. Our goals is to elucidate the regulatory mechanism through which grafting enhances salt tolerance. Methods: The salt-sensitive tomato variety Zhongza 9 and the strongly salt-tolerant tomato rootstock variety QZ-006 (selected by the research group in the early stage) were used as experimental materials and were purchased from the Vegetable and Flower Institute of the Chinese Academy of Agricultural Sciences (Beijing, CHN) and Beijing Kaixingelin Agricultural Technology Co., Ltd. (Beijing, CHN)；The leaves of the seedlings of every sample was added to 5 mL of HNO3 (65%~68%) after they were heated in a microwave digestion system for 2~3 hours；RNA-seq libraries were sequenced on an Illumina HiSeq X Ten platform；qRT‒PCR was performed according to the instructions of a Fast Super EvaGreen qPCR Master Mix Kit (US Everbright®, Inc.)；The amino acid contents in the tomato leaves were calculated by the external standard method. The chlorophyll of the seedlings was extracted with acetone-ethanol (1:1) ；An indirect enzyme-linked immunosorbent assay (ELISA) was used to determine auxin (IAA), gibberellin (GA), cytokinin (ZR), brassinolide (BR), abscisic acid (ABA), jasmonic acid (JA) and salicylic acid (SA) contents, and kit purchased from ThermoFisher Scientific Co., Ltd. (USA). Endogenous ethylene (ETH) was collected, fixed and determined according to the methods of Ling (Ling et al.,2008) using a Shimadzu 2010 gas chromatograph equipped with a hydrogen flame ion detector. ETH standard gas was purchased from Sigma Company. Results: Compared with the NGS, the GSs were more salt tolerant, and the Na+ content in the leaves decreased significantly. Through transcriptome sequencing data analysis of 36 samples, we found that GSs exhibited more stable gene expression patterns, with a lower number of DEGs. WRKY and PosF21 transcription factors were significantly upregulated in the GSs compared to the NGSs. Moreover, the GSs presented more amino acids, a higher photosynthetic index and a higher content of growth-promoting hormones. The main differences between GSs and NGSs were in the expression levels of genes involved in the BR signalling pathway, with significant upregulation of XTHs. Conclusions: Our study demonstrates that grafting on salt tolerant rootstocks can bring different metabolic processes and transcription levels changes to scion leaves, thereby the scion leaves show stronger salt tolerance. This information provides new insight into the mechanism underlying tolerance to salt stress regulation and provides useful molecular biological basis for improving plant salt resistance.
