Hrp Genes

The soilborne pathogen Ralstonia solanacearum is the causal agent of bacterial wilt and attacks more than 200 plant species, including some legumes and the model legume plant Medicago truncatula. We have demonstrated that M. truncatula accessions Jemalong A17 and F83005.5 are susceptible to R. solanacearum and, by screening 28 R. solana-cearum strains on the two M. truncatula lines, differential interactions were identified. R. solanacearum GMI1000 infected Jemalong A17 line, and disease symptoms were dependent upon functional hrp genes. An in vitro root inoculation method was employed to demonstrate that R. solanacearum colonized M. truncatula via the xylem and intercellular spaces. R. solanacearum multiplication was restricted by a factor greater than 1 × 105 in the resistant line F83005.5 compared with susceptible Jemalong A17. Genetic analysis of recombinant inbred lines from a cross between Jemalong A17 and F83005.5 revealed the presence of major quantitative trait loci for bacterial wilt resistance located on chromosome 5. The results indicate that the root pathosystem for M. truncatula will provide useful traits for molecular analyses of disease and resistance in this model plant species.

Severe Disturbance

Much of Australia has extremely impoverished soil. Phosphate is particularly deficient. The major difficulty in revegetating these soils after severe disturbance is that plant survival and growth is unpredictable. Mycorrhizas are associations between soilborne fungi and the roots of plants. Of particular interest are the arbuscular mycorrhiza (AM) whose fungi form an internal colony in the roots of some 70% of all plant species. In AM, the fungi function as extensions of the root system, enabling the plant to increase uptake of non-labile minerals, especially phosphorus (P), from soil. The fungus gains its organic energy from the plant, and can only be maintained in the presence of living roots.

First Time

The results of studies of the mycorrhizal status of plant species spontaneously established on the soda heap located in Jaworzno (Upper Silesia, Poland) are presented. Additionally, the species of arbuscular fungi of the phylum Glomeromycota extracted from field-collected rhizosphere substrate samples of the heap are showed. Arbuscular mycorrhizae were described in 17 plant species. Five <em>Glomus</em> spp. were recognized in the spore populations of arbuscular fungi isolated. The investigation presented in this paper for the first time revealed <em>Centaurea stoebe</em> and <em>Trifolium montanum</em> to be hosts of arbuscular fungi.

Mycorrhizal status of plants colonising the zinc wastes in Katowice was surveyed. In total 69 vascular plant species (25 families) appearing on the investigated area have been noted. More than 60% of them were mycorrhizal. Non-mycorrhizal species, such as <em>Cardaminopsis arenosa</em> and <em>Silene vulgaris</em> dominated the early successional part of the zinc heap. <em>Tussilago farfara</em> was the only AM plant there, however, no arbuscules were developed at this stage. The number of AM species was increased on the 20 years old part of the zinc wastes and on the older 30-50 years old areas. AM plants constituted about 60% of the total number of species there. The frequency of particular AM species was the highest on the oldest part of the investigated area. The usefulness of the results for restoration practices was discussed.
