“…Grafting technology is widely used in the production of vegetables, fruits, and other important economic crops, and has been used to protect many important crops from soil-borne diseases [4][5][6][7]. The current study found that a resistant tobacco cultivar used as the rootstock or scion improved the disease resistance of the susceptible cultivar, and the difference in exudate composition might contribute to that.…”

“…Grafting with disease-resistant rootstock is considered to be an effective way to control plant soil-borne diseases, and has been widely applied in the production of fruits, vegetables, cotton, and other economic crops [4][5][6][7]. Apart from increasing disease resistance, grafting can also enhance plant stress resistance, promote growth and improve some traits [8].…”

The composition and allelopathy to Phytophthora nicotianae (the causal agent of tobacco black shank disease) of root exudates from a resistant tobacco (Nicotiana tabacum L.) cultivar Gexin 3, a susceptible cultivar Xiaohuangjin 1025 and their reciprocal grafts were investigated. Grafting with disease-resistant rootstock could improve resistance to black shank; this is closely related to the allelopathy of root exudates. The root exudates from the resistant cultivar inhibited the growth of P. nicotianae, while those from the susceptible cultivar promoted the growth; the grafting varieties had intermediate properties. The root exudate composition differed among cultivars. Gexin 3 was rich in esters and fatty acids, while Xiaohuangjin 1025 contained more hydrocarbons and phenolic acids. The composition of root exudates of grafted cultivars as well as their allelopathy to P. nicotianae were altered, and tended to be close to the composition of cultivar used as rootstock. Eugenol, 4-tert-butylphenol, mono (2-ethylhexyl) phthalate, 4-hydroxybenzoic acid, 2,6-di-tert-butylphenol, dipropyl phthalate, and methyl myristate were identified as the main compounds contributing to inhibitory properties of root exudates. Sorbitol was suggested to play a role in disease induction. Overall, rootstock–scion interaction affected the composition of tobacco root exudates, which may be attributed to the different disease resistance among grafted plants, rootstock and scion.

“…Different control strategies, such as chemical, biological, and cultural practices, can reduce bacterial wilt severity, but none of them are effective ( Yuliar et al 2015 ). Development and use of resistant cultivars is the most effective approach to control bacterial wilt ( Abebe et al 2016 , Huet 2014 , Scott et al 2005 , Wang et al 2018 ). Breeding for bacterial wilt-resistant cultivars has been challenging due to the polygenic nature of resistance, broad host range, variability of the pathogen strains, and effect of environmental factors that directly influence the phenotypic expression of the disease ( Danesh et al 1994 , Fegan and Prior 2005 , Hayward 1991 , Lee et al 2011 , Thoquet et al 1996b , Tran and Kim 2010 ).…”

Bacterial wilt, caused by the Ralstonia pseudosolanacearum species complex, is an important vascular disease that limits tomato production in tropical and subtropical regions. Two major quantitative trait loci (QTL) of bacterial wilt resistance on chromosome 6 ( Bwr-6 ) and 12 ( Bwr-12 ) were previously identified in Solanum lycopersicum ‘Hawaii 7996’; however, marker-assisted breeding for bacterial wilt resistance is not well established. To dissect the QTL, six cleaved amplified polymorphic sites (CAPS) and derived CAPS (dCAPS) markers within the Bwr-6 region and one dCAPS marker near Bwr-12 were developed, and resistance levels in 117 tomato cultivars were evaluated. Two markers, RsR6-5 on chromosome 6 and RsR12-1 on chromosome 12, were selected based on the genotypic and phenotypic analysis. The combination of RsR6-5 and RsR12-1 effectively distinguishes resistant and susceptible cultivars. Furthermore, the efficiency of the two markers was validated in the F 3 generation derived from the F 2 population between E6203 (susceptible) and Hawaii 7998 (resistant). Resistant alleles at both loci led to the resistance to bacterial wilt. These markers will facilitate marker-assisted breeding of tomato resistant to bacterial wilt.
