“…In particular, tolerant rootstock compared with the susceptible ones downregulate energy metabolism‐related proteins, some defense‐related proteins and several key enzymes involved in ROS scavenging, thus pointing out the role of the rootstock in influencing scion response to internal and external cues. The effect of rootstock on scion gene expression modulation has been widely documented in the Cucurbitaceae family (Edelstein et al ), grapevine (Marè et al ), eggplant (Zhang et al ) and apple tree (Jensen et al , , ). The downregulation of ROS scavenging enzymes, as discussed before, may affect production of ROS long distance auto‐propagating signals responsible for the downstream modulation of the scion response to virus infection.…”

Citrus tristeza virus (CTV) is the causal agent of various diseases with dramatic effects on citrus crops worldwide. Most Citrus species, grown on their own roots, are symptomless hosts for many CTV isolates. However, depending on different scion-rootstock combination, CTV infection should result in distinct syndromes, being 'tristeza' the more severe one, leading to a complete decline of the susceptible plants in a few weeks. Transcriptomic analyses revealed several genes involved either in defense response, or systemic acquired resistance, as well as transcription factors and components of the phosphorylation cascades, to be differentially regulated during CTV infection in Citrus aurantifolia species. To date little is known about the molecular mechanism of this host-pathogen interaction, and about the rootstock effect on citrus response to CTV infection. In this work, the response to CTV infection has been investigated in tolerant and susceptible scion-rootstock combinations by two-dimensional gel electrophoresis (2DE). A total of 125 protein spots have been found to be differently accumulated and/or phosphorylated between the two rootstock combinations. Downregulation in tolerant plants upon CTV infection was detected for proteins involved in reactive oxygen species (ROS) scavenging and defense response, suggesting a probable acclimation response able to minimize the systemic effects of virus infection. Some of these proteins resulted to be modulated also in absence of virus infection, revealing a rootstock effect on scion proteome modulation. Moreover, the phospho-modulation of proteins involved in ROS scavenging and defense response, further supports their involvement either in scion-rootstock crosstalk or in the establishment of tolerance/susceptibility to CTV infection.

“…It has been suggested that transgenic rootstocks could be used to produce nongenetically modified fruit from a nontransgenic scion, to avoid some regu latory issues, but recent descriptions of the movement of nucleic acids across the graft junction (Zhang et al, 2008;Haroldsen et al, 2012;Tsaballa et al, 2013;Avramidou et al, 2015), and the broad nature of the regulatory framework cur rently make this an unworkable proposition.…”

Vegetable Grafting: Principles and Practices

This chapter explores how genetic diversity can be exploited more deeply to create new rootstock cultivars, and describes the current and future breeding strategies applicable to rootstocks. It considers how to combine different sources of genetic variation, for example by overcoming species barriers, and how to select useful rootstocks. The many traits that can be associated with the root system or conferred by a rootstock to the scion are outlined. The impact of the practice of grafting on breeding strategies is also discussed.

“…For example, it has been documented that some rootstocks may influence the nutritional characteristics of fruits (Martinez-Ballesta et al, 2008) and even get translocation of toxic compounds into the scion, as happened with the first tomato grafts in wild solanum D. stramonium (Kubota et al, 2008). It has recently been documented that the effect of the rootstock towards the graft can even up the genetic level (Zhang et al, 2008).…”
