“…However, there is not much literature concerning the control of SRE by means of resistance and this may be linked to factors such as poor correlation between tuber soft rot and blackleg resistance (1,13,16,19,35). Although several studies have addressed various aspects of tuber resistance, even fewer studies have investigated stembased resistance mechanisms.…”

Pectobacterium carotovorum subsp. brasiliense is a newly identified member of the potato soft rot enterobacteriaceae. The pathogenesis of this pathogen is still poorly understood. In this study, an mCherry-P. carotovorum subsp. brasiliense-tagged strain was generated to study P. carotovorum subsp. brasiliense-potato plant interactions. Prior to use, the tagged strain was evaluated for in vitro growth, plasmid stability, and virulence on potato tubers and shown to be similar to the wild type. Four potato cultivars were evaluated for stem-based resistance against P. carotovorum subsp. brasiliense. Confocal laser-scanning microscopy and in vitro viable cell counts showed that P. carotovorum subsp. brasiliense is able to penetrate roots of a susceptible potato cultivar as early as 12 h postinoculation and migrate upward into aerial stem parts. Due to the phenotypic differences observed between tolerant and susceptible cultivars, a comparison of P. carotovorum subsp. brasiliense colonization patterns in these cultivars was undertaken. In the susceptible cultivar, P. carotovorum subsp. brasiliense cells colonized the xylem tissue, forming "biofilm-like" aggregates that led to occlusion of some of the vessels. In contrast, in the tolerant cultivar, P. carotovorum subsp. brasiliense appeared as free-swimming planktonic cells with no specific tissue localization. This suggests that there are resistance mechanisms in the tolerant cultivar that limit aggregation of P. carotovorum subsp. brasiliense in planta and, hence, the lack of symptom development in this cultivar.Additional keyword: Dickeya.

“…In Uganda, clones 388575.5 and 388575.9 both from CIP are moderately resistant to bacterial wilt in the cool areas, while clones 390005.11, 388574.2B, and 388580.18A are moderately resistant to bacterial wilt in the warm areas (Kaguongo et al, 2008). In Kenya, varieties Kenya Dhamana (CIP-800228), Kenya Sifa, Kenya Karibu, Mauritius clone (89016), and Cruza-148 (CIP-720118) were rated as resistant to bacterial wilt, while varieties Asante (CIP-381381.20), Tigoni (CIP-381381.13), Nyayo, and Dutch Robyjin were highly susceptible (Ateka et al, 2001).To control bacterial wilt of potatoes better, continuous development of resistant varieties is needed (Fock et al, 2001;.…”

“…Some wild or cultivated species related to Solanum tuberosum are known to be highly tolerant to bacterial wilt, and thus are potential sources of resistance (Fock et al, 2001). Unfortunately, hybrids of potato with resistant genotypes of the wild Solanum chacoense, Solanum sparsipillum, and Solanum multidissectum revealed some traits of wildness such as high glycoalkaloid content in addition to moderate levels of resistance to bacterial wilt (French et al, 1998).…”

This article gives a general overview of bacterial wilt of potatoes and its management. It also highlights the potential of host resistance as an important component of integrated management of bacterial wilt in Kenya. Bacterial wilt has spread to all potato growing areas in Kenya, affecting over 70% of potato farms and causing yield losses of between 50 to 100%. This disease has no effective means of control because crop protection chemicals are ineffective and expensive and biological control agents are ineffective. In addition, phytosanitary methods such as quarantine are either expensive or difficult to apply and cultural methods such as crop rotations are largely impractical because the farms are too small to allow effective rotation, the pathogen has a wide host range, and it persists for long in the soil. Development of resistant cultivars could therefore play an important role in managing the disease. More resistant potato clones have recently been identified by CIP scientists, and this resistance needs to be incorporated into the popular but susceptible Kenyan potato cultivars so as to increase potato production in Kenya. For better results, use of high resistant varieties may be coupled with use of disease-free tubers and clean fields.

“…Some success has been reported with chemical control of brown rot (Murakoshi and Takahashi 1984), soil fumigants (Weingartner and Shumaker 1988), resistant varieties (Fock et al 2001;Lopez and Biosca 2004), and antibiotics (Habashy et al 1993). Additionally, chemical control (pesticides) with its residues has been reported to have hazardous effects in Europe and Egypt (Sylvander and Le Floc'hWadel 2000;Parrott and Kalibwani 2004).…”
