“…Strains belonging to the Pssc have been reported to contaminate seeds of numerous annual plant species such as bean (Taylor et al 1979), carrot (Almeida et al 2013), celery (Pohronezny et al 1994), coriander (Refshauge et al 2010), cucumber (Kritzman and Zutra 1983), leek (Ikene et al 2003), pea (Elvira-Recuenco and Taylor 2001), pepper (Buonaurio and Scortichini 1994), soybean (Parashar and Leben 1972), sorghum (Gaudet and Kokko 1986), tomato (Schneider and Grogan 1977), crucifers (Schofield et al 2012) and wheat (Valencia-Botín and Cisneros-López 2012). Seed infestation is considered as the main cause of disease epidemics on many plant species (Rennie 1998), such as in recent epidemics on crucifers in California and other parts of the world (Takikawa and Takahashi 2014).…”

“…However, it is possible that the pathogen can survive for a long period in regions with cooler summer temperatures, mostly under constant soil moisture. Indeed, the ability of the Pssc to survive in the soil for a longer period has been demonstrated especially when the source of the inoculum was associated with plant debris and in the presence of constant soil moisture (Kritzman and Zutra 1983). It is also worth noting that strains in the Pssc have been isolated from the rhizosphere of crops and weeds (Knoche et al 1987;Valleu et al 1944).…”

The plant pathogenic Pseudomonas syringae species complex (Pssc) causes diseases of hundreds of species of monocots, herbaceous dicots and woody dicots worldwide. On annual plants, reports of disease caused by the Pssc have markedly increased in the last years. Hence, efforts are needed to mitigate the consequences of increasing disease outbreaks and to understand the underlying epidemiological factors. Here, we have reviewed the literature to highlight the salient features of the Pssc as pathogens of annual plant species and to underscore what remains unknown about the diseases they cause. The major points are as follows: (1) Since only the beginning of this century, 72 reports of disease outbreaks in 20 countries have been associated with the Pssc on over 40 annual plant species; (2) disease incidence caused by the Pssc on annual plants ranges from 50 to 100 % in epidemic years; (3) seed infestation is the main cause of long-distance pathogen dissemination; (4) foliar disease symptoms are very common on annual plants although the Pssc causes symptoms on fruits of bean, cantaloupe, cucumber, okra and tomato; (5) environmental factors such as rainfall and humidity have important roles in the Pssc disease epidemiology; (6) several new disease reports contradict the concept of the so-called pathovar, thereby raising the question of whether strains in the Pssc are mostly generalists rather than specialists as currently believed; and (7) disease control of annual plants is frequently based on approaches integrating biological, chemical and cultural measures with available plant resistance.

“…Most studies of this bacterium have corroborated its poor capacity to survive in soils. Crop soils in particular do not seem to have a critical role as a habitat, especially without the incorporation of diseased plant tissue (Kritzman and Zutra, 1983;McCarter et al, 1983;Riffaud and Morris, 2002;Zhao et al, 2002;Hollaway et al, 2007;van Overbeek et al, 2010). However, in alpine ecosystems, Reynolds and Ringelberg (2008) reported the successful transfer of non-indigenous P. syringae populations from snow to soil where the bacterium was detected up to 80 days after transfer.…”

Soil water flow is a source of the plant pathogen Pseudomonas syringae in subalpine headwaters

The airborne plant pathogenic bacterium Pseudomonas syringae is ubiquitous in headwaters, snowpack and precipitation where its populations are genetically and phenotypically diverse. Here, we assessed its population dynamics during snowmelt in headwaters of the French Alps. We revealed a continuous and significant transport of P.syringae by these waters in which the population density is correlated with water chemistry. Via in situ observations and laboratory experiments, we validated that P.syringae is effectively transported with the snow melt and rain water infiltrating through the soil of subalpine grasslands, leading to the same range of concentrations as measured in headwaters (10(2) -10(5) CFU l(-1) ). A population structure analysis confirmed the relatedness between populations in percolated water and those above the ground (i.e. rain, leaf litter and snowpack). However, the transport study in porous media suggested that water percolation could have different efficiencies for different strains of P.syringae. Finally, leaching of soil cores incubated for up to 4 months at 8°C showed that indigenous populations of P.syringae were able to survive in subalpine soil under cold temperature. This study brings to light the underestimated role of hydrological processes involved in the long distance dissemination of P.syringae.

“…In general, P. syringae strains do not survive as long in nontreated soil as they do in pasteurized soil (2,3, 15,19,25). In the laboratory studies reported here, heat labile factors, probably biological in nature, may have played a role in the maintenance of the pathogen populations since population levels of P. syringae pv.…”
