Doktorand der AG Biodiversität und Evolution der Pflanzen


Meine Doktorarbeit ist ein Teil das DynaCom Projects (Spatial community ecology in highly dynamic landscapes: from island biogeography to metaecosystems) gefördert von der Deutschen Forschungsgemeinschaft.  Mein Ziel ist ein Verständnis der räumlichen Verbreitung von Pflanzen-Pilz Interaktionen in Salzmarschen der Nordsee zu bekommenn. Unsere Hypothese ist, dass die Symbiose zwischen Pflanzen und Pilzen in der Salzmarsch die Besiedelungswahrscheinlichkeit beider Symbiosepartner erhöht (Symbiose als Verbreitungsmerkmal), die Besiedelungsdauer im Habitat verlängert (Symbiose als Fraßmerkmal) und die Widerstandsfähigkeit gegenüber wechselnden Umweltbedingungen stärkt (Symbiose als Toleranzmerkmal). Für diese Untersuchungsziele werden Zellgröße und Ploidie verschiedener Halophyten unterschiedlicher Ploidiestufen und zwei Pilzgruppen (Mykorrhiza und Dark septate endophytes [DSE]) bestimmt.

      abstract = {Endophytic fungi are known to be present in roots of salt marsh plants, but their ecological role in this symbiosis is still largely unknown. Generally considered parasitic or saprophytic, they may still be mutualistic, at least under certain circumstances. Among salt marsh plants, Salicornia spp. are recognized as particularly salt-tolerant and their frequent colonization by root endophytes has also been reported. This study aimed to investigate whether the inoculation of Salicornia with different root endophytes isolated from field-collected Salicornia affects biomass production, nutrient uptake and photosynthesis (assessed via chlorophyll fluorescence). In addition, we investigated whether fungal inoculation confers tolerance to salt stress given that endophytes are suggested to increase salt tolerance and improve plant fitness in other less salt-tolerant plants. The inoculation of Salicornia with an isolate of the genus Stemphylium positively influenced total biomass production and nitrogen concentration in roots at optimum salinity condition (150 mM NaCl). However, under salt stress (650 mM NaCl), no significant effects of fungal inoculation on biomass production and photosynthesis were observed. Further, positive and negative effects of fungal inoculation on nutrient concentrations were observed in roots and shoots, respectively. Our results indicate that different endophytic fungi and their interaction result in distinct fungal species-specific plant growth responses of Salicornia under different growth conditions.},

      abstract = {During a survey of oomycetes in a mangrove area of S{\~{a}}o Paulo state, Brazil, a high number of isolates of Halophytophthora and related genera were recovered from leaves and water samples. In this study, we analysed the morphology and phylogenetic relationships of the isolates of Halophytophthora along with four ex-types provided by CBS-KNAW Culture Collection. Maximum likelihood and Bayesian analyses of the internal transcribed spacer (ITS) and large subunit (LSU) rDNA regions confirmed previous evidence of the polyphyly of the genus and revealed the presence of two yet undescribed species. The two new species, Halophytophthora souzae and H. insularis, belong to the Halophytophthora sensu stricto clade and are described herein based on their morphology and/or phylogenetic position.},

      abstract = {A survey of Pythium and Phytopythium species was conducted in hydroponics systems located in the metropolitan region of S{\~{a}}o Paulo and nearby cities, SP, Brazil. Different samples including water from artesian well, nutrient solution, substrates used for seedlings production and roots of hydroponically grown crops were collected and baited for Pythium and Phytopythium recovery. It was possible to isolate Pythium species from the four types of samples while Phytopythium species were isolated only from the substrates. The species were identified according to their morphological features and phylogenetic placement in a combined analysis of the ITS rDNA and COI mDNA regions within eight different taxa: Pythium kashmirense, P. middletonii, P. oopapillum, P. periplocum, P. segnitium, Pythium group F, Phytopythium helicoides and Phy. vexans. The isolates identified as Pythium group F were the most frequent species. While Pythium species were distributed in clades B, D and E, Phytopythium were distributed in clades 2 and 3. This study brings important information about the diversity of these species in hydroponic systems in Brazil and provides sequences of species rarely reported such as P. kashmirense, P. oopapillum and P. segnitium.},
