“…Furthermore, Stark-Lorenzen et al (1997) reported that rice plants transformed with the grapevine stilbene synthase gene exhibited enhanced resistance against the rice blast pathogen P. oryzae. However, in transformed tomato, the stilbene synthase gene did not enhance resistance against B. cinerea (Kobayashi et al, 2000). Considering the data, the results for resistance by transforming with stilbene synthase gene are variable.…”

Genetic engineering is being used to enhance disease resistance and nutritional value of crops including rice plant. Considering the fast-growing agricultural biotechnology and rapidly increasing global area of transgenic crops, the risk evaluation on environment is necessary. In this study, we surveyed the difference of disease occurrence between transgenic rice variety, Iksan526 transformed with peanut stilbene synthase gene and non-transgenic rice varieties, Dongjin and Nampyeong in the field. Moreover, the possibility of gene transfer from transgenic rice to bacterial and fungal pathogens was investigated. The results of this study indicated that there was no significant difference in the occurrence and severity of the diseases between Iksan526 and Dongjin or Nampyeong. In addition, the results suggested that rice pathogen, such as Xanthomonas oryzae pv. oryzae, Rhizoctonia solani and Magnaporthe grisea did not take up stilbene synthase and bar genes under natural conditions. Moreover the transformed DNA was not transferred to the pathogens even in repetitive contacts.

“…However, some STS GM plants produced piceid or failed to produce resveratrol. For instance, the transgenic kiwifruit produced by Kobayashi et al (2000), transgenic white poplar generated by Giorcelli et al (2004) and transgenic strawberry produced by Hanhineva et al (2009) were more susceptible to fungi. Four hypotheses have been proposed to explain stilbene GM plants that lack resistance or are more susceptible to fungal pathogens.…”

“…This affects stilbene production and may interfere with secondary biosynthetic pathways (Hain et al 1990(Hain et al , 1993Thomzik et al 1997). Second, these GM plants may produce resveratrol glucoside (piceid), which has little or no antifungal activities compared with resveratrol and its dehydrodimer δ-viniferin, which are more effective against fungus (P. viticola) zoospores in grapevines (Kobayashi et al 2000;Giorcelli et al 2004;Chang et al 2011). Third, host-pathogen relationships determine the antifungal activity of foreign resveratrol production .…”

ABSTRACT Resveratrol is a stilbenoid and phytoalexin produced in response to stresses, such as wounding, and pathogen attacks by bacteria or fungi. Two resveratrol rice lines, Iksan515 and Iksan526, were used to examine resistance against Korean pathogen races for bacterial blight, leaf blast, and brown leaf spot. The screening test for bacterial blight demonstrated an increased susceptibility of both transgenic lines to K1 race, and a more susceptible Iksan515 to K2. Phenotypic evaluation for resistance to brown leaf spot also revealed the susceptibility of Iksan526 to the disease which did not significantly differ from the isogenic variety 'Dongjin', and a slightly more susceptible Iksan515 to the disease compared to check. When the lines were screened with three races (KJ301, KJ101 and KJ133) of leaf blasts in the field, both transgenic lines exhibited resistance but at the same level with 'Dongjin'. Our overall findings suggest that foreign phytoalexin resveratrol production in transgenic rice lines transformed with resveratrol synthase gene did not confer resistance against fungal and bacterial diseases.

“…The April 2008 purchase of Sirtris by Glaxo Smith Kline (Pollack, 2008) demonstrates that big pharma is now showing an interest in the arena of food functionality. Resveratrol glucoside production has been achieved in alfalfa (Medicago sativa), wheat, kiwi (Actinidia deliciosa), and tomato (Stark-Lorenzen et al, 1997;Hipskind and Paiva, 2000;Kobayashi et al, 2000;Szankowski et al, 2003;Niggeweg et al, 2004;Giovinazzo et al, 2005;Shin et al, 2006).…”
