The list of species of the plant parasitic nematodes presented in this paper (133 species belonging to 14 families) is based on the results of faunistic research conducted in the Wielkopolska region by Polish nematologists up until the year 2010, and the results obtained from the project “Elaboration of Innovative Methods for Rapid Identification of Nematodes Causing Damage to the Economy” managed by the Museum and Institute of Zoology of the Polish Academy of Sciences. During the two years of the project (2010-2011) we found 21 species of nematodes which had not yet been reported in the list of species from the Wielkopolska region. Two of them were reported for the first time in Poland.

Agricultural productivity is strongly affected by different abiotic stresses, among which water stress is the major environmental constraint limiting plants growth. The primary reason for water stress is drought or high salt concentration in soil (salinity). Because both of these stress factors lead to numerous physiological and biochemical changes in plants and result in serious loss in yields, there is a pressing need for finding the effective ways for increasing crops’ resistance to stress factors. One of the alternative methods involving alleviation of negative stress effects might be application of silicon as a fertiliser (root or foliar supply). Many plants, particularly monocotyledonous species, contain large amounts of Si (up to 10% of dry mass). In spite of the high Si accumulation in plants (its amount may equal concentration of macronutrients), until now it has not been considered as an essential element for higher plants. Many reports have shown that silicon may play a very important role in increasing plant resistance to noxious environmental factors. Hence, Si is recognised as a beneficial element for plants growing under biotic and abiotic stresses. The main form of Si which is available and easily taken up by plants is monosilicic acid (H4SiO4). Plants take up Si from soil solution both passively and actively. Some dicotyledonous plants such as legumes tend to exclude Si from tissues – rejective uptake. These plants are unable to accumulate Si and they do not benefit from silicon. Under water stress conditions, silicon might enhance plants’ resistance to stress and ameliorate growth of plants. These beneficial effects may result from better and more efficient osomoregulation, improved plant water status, reduction in water loss by transpiration, maintenance of adequate supply of essential nutrients, restriction in toxic ions uptake and efficient functioning of antioxidative mechanisms. Based on the current knowledge and presented data, it can be concluded that the role of Si in plants is not restricted to formation of physical or mechanical barrier (as precipitated amorphous silica) in cell walls, lumens and intercellular voids. Silicon can also modulate plants’ metabolism and alter physiological activities, particularly in plants subjected to stress conditions. However, in some plants, increased silicon supply does not improve plant growth. Hence, a better understanding of the interactions between silicon application and plant responses will contribute to more efficient fertiliser practices, especially under stress conditions.

The array of genes isolated and characterised from Craterostigma to date allow many insights to be made into the protection mechanisms underlying the desiccation tolerance phenomenon and drought-induced changes in gene expression. However, more work is necessary to define which gene products positively contribute to stress tolerance and which may be considered as secondary stress metabolites or as gene regulators. It is apparent that the gene regulatory mechanisms involved are complex, but future work with more refined biochemical and genetic approaches, together with the analysis of defined mutants will greatly help to dissect the important area of desiccation perception, perhaps faciliate manipulation of desiccation tolerance in a genetic engineering context, and undoubtedly bring much progress in the coming years.
