“…oryzae, respectivamente. Plantas de pêra e maçã foram transformadas para expressar o gene atacina E, e mostraram uma suscetibilidade reduzida a Erwinia amylovora, agente causal do "fire blight", em testes realizados "in vitro" ou em casa- de-vegetação (NORELLI et al, 1994;KO et al, 2000;REYNOIRD et al, 1999), e também em condições de campo (NORELLI et al, 1999). Boscariol et al (2006) obtiveram plantas de laranja 'Hamlin' expressando o gene attA, que mostraram uma significativa redução na suscetibilidade ao cancro cítrico.…”

“…atroseptica [8]. Transgenic apple expressing the SB-37 lytic peptide analogue showed increased resistance to E. amylovora, pathogen for fire blight, in field tests [110]. A high degree of resistance to E. carotovora was also observed in potato tubers expressing the 34-aa chimaeric peptide MsrA1, which contains a C-terminal eight-aa segment from cecropin A and an N-terminal 16-aa segment of melittin and a 26-aa antibacterial peptide from bee venom [114].…”

“…Transgenic pear and apple-expressing attacin genes had significantly enhanced resistance to E. amylovora in in vitro and greenhouse [78]. In field tests, reduction of fire blight disease has been observed in transgenic apples expressing attacin genes [110]. Transgenic apple expressing attacin targeted to the inter-cellular space, where E. amylovora multiplies before infection, had significantly reduced fire blight, even in apple plants with low attacin production levels [78].…”

Improvement for Bacterial Wilt Resistance in Potato By Conventional and Biotechnological Approaches

Bacterial wilt (BW) of potato caused by the bacterium Ralstonia solanacearum (Rs) is considered a serious problem particularly in tropical, subtropical and warm temperate regions. Chemical-, cultural-and biological control of BW has limited success. Thus, the control of BW through resistance breeding and biotechnology is considered to be very important and necessary. Rs is considered a 'species complex' and has significant variation at physiological, serological and genetic levels. The bacterium has an unusually wide host range with over 400 hosts belonging to more than 50 botanical families. A large number of Solanum species have been screened for resistance to this bacterium, but so far no Solanum species has been found to have complete immunity. A high degree of resistance to Rs was found only in S. phureja, a diploid relative of cultivated tetraploid potatoes. The resistance has been transferred from S. phureja to cultivated potatoes through introgression breeding as well as somatic hybridization. Although moderate to highly resistant potato varieties have been released, high frequency of latent infection in tubers is still a major problem. Further, the resistant cultivars are not adapted to different agro-climatic zones and are not effective against all the strains of the pathogen. Biotechnological approaches involving the use of antimicrobial peptides, plant defence genes and plant resistance genes are being tried. This paper reviews the global situation with regard to screening of genetic resources and their utilization in resistance breeding for BW in potato and also the status and the opportunities that biotechnology offers to combat this disease.

“…Rootstocks resistant to E. amylovora have also been identified [15,16], but some of the more common dwarfing rootstocks employed, such as M26, are among the most susceptible to fire blight. Recent advances in the transformation of apple hold significant promise for over coming past deficiencies in merging resistance with desirable horticultural traits in apple [17,18].…”
