Grafting can enhance the tolerance of vegetable crops to soilborne diseases. The aim of this study was to investigate whether different tomato scion-rootstock combinations may affect the plant susceptibility to Fusarium oxysporum f. sp. radicis-lycopersici (FORL), the causal agent of crown and root rot. A proteomic approach was used to investigate whenever the protein repertoire of the rootstoc...

Annual yields per tree for ‘Starkspur Supreme Delicious’ apple (Malus domestica Borkh.) trees on nine size-controlling rootstock were related linearly to number of fruit per tree at harvest each year, independent of rootstock. Mean fruit weight was inversely and less closely related to number of fruit per tree when adjusted for tree size (fruit load). Annual yield-fruit count data for 9 years a...

In order to clarify the influence of the rootstock cultivar and fruit storage on the texture of cucumber (Cucumis sativus L.) fruit, we examined the physical properties of the fruit, i.e., flesh firmness, placental firmness, skin toughness, and the crispness index. Cucumber fruits from own-rooted plants and from plants grafted onto the three rootstock cultivars of ‘Shin-tosa’ (Cucurbita maxima ...

Grafting is a well-established practice to facilitate asexual propagation in horticultural and agricultural crops. It has become a method for studying molecular aspects of root-to-shoot and/or shoot-to-root signaling events. The objective of this study was to investigate differences in gene expression between the organs of the scion and rootstock of a homograft (Arabidopsis thaliana). MapMan an...

Serr variety to which all rootstocks were (!.raftedhas grown and produced on all rootstock selections although some have grown faster and produce more than others. Northern California Black Walnut (Juglans hindsii) and ~. major grow to moderate size and have good production potential. The paradox seedling, paradox cutting and Royal seedling grow to large size and have a good production potentia...

Professor Hume was right: rootstocks are critical and much is still to be learned. Rootstocks and scions are the foundation of many tree fruit industries of the world. Together, those components establish profitability, but it can be argued that the rootstock is the critical component; otherwise, scions would be grown on their own roots everywhere. There is no precedent for the failure of a cit...

Xylella fastidiosa (Xf) is the causative agent of Pierce’s Disease (PD). Collectively, a team of researchers (Lindow, Dandekar, Labavitch/Powell and Gilchrist) has identified or constructed and advanced the evaluation of five (Table 1) novel genes (DNA constructs) that, when engineered into grapevines, suppress symptoms of PD by reducing the titer of Xf in the plant, reducing its systemic sprea...

INTRODUCTION Collectively, a team of researchers (Lindow, Dandekar, and Gilchrist) identified, constructed and advanced to field evaluation five novel DNA constructs (Table 1) that, when engineered into grapevines, suppress symptoms of Pierce’s Disease (PD) by a) reducing the titer of Xylella fastidiosa (Xf) in the plant, b) reducing systemic spread of the bacteria or c) blocking Xf’s ability t...

To evaluate the role of root-synthesized ABA in regulating growth and stomatal behaviour under well-watered conditions, isogenic wild-type (WT) and ABA-deficient flacca (flc) tomato (Solanum lycopersicum) were reciprocally and self-grafted just below the cotyledonary node. Since flc scions had lower leaf water potentials due to higher transpiration rates, a subset of all graft combinations was ...

"Lane Late" sweet orange grafted on six different citrus rootstocks and grown in the Guadalquivir valley (Seville, Spain) were picked at different ripening stages in two consecutive seasons to characterize their antioxidant activity (free radicals scavenging activity, reducing power and lipid peroxidation inhibition) and quantify their main antioxidant compounds (vitamin E and vitamin C). Linea...
