Some years ago a fossil lake basin was found in the northeastern part of the former Rhine-pied- mont-glacier, situated between the endmoraine system ofthe elassical Riß- andWürm glacia- tions, respectively. The lacustrine sediments contain the pollenflora ofthe Eemian interglacial. They are intensively thrusted. These sediments are eovered by a loam-layer, rieh in elasts. The thickness of this loam-layer varies between at least 170 and 400 cm. It consists in its major part of loess-loam and solifluction material. Yet just on top of the lake sediments mentioned an in- tensively compressed loam, characterized by quarzgrains with all features of glacially pressed material, together with striated elasts is met with. It strongly resembles atil!. Ifthis is true, the stratigraphie division ofthe last glaciation strongly deviates from the hitherto accepted scheme, incorporating an early glacier advance, long before the elassical young-endmoraine systems of the Würm glaciation were formed.

We have constructed cDNA microarrays for soybean (Glycine max L. Merrill), containing approximately 4,100 Unigene ESTs derived from axenic roots, to evaluate their application and utility for functional genomics of organ differentiation in legumes. We assessed microarray technology by conducting studies to evaluate the accuracy of microarray data and have found them to be both reliable and reproducible in repeat hybridisations. Several ESTs showed high levels (>50 fold) of differential expression in either root or shoot tissue of soybean. A small number of physiologically interesting, and differentially expressed sequences found by microarray analysis were verified by both quantitative real-time RT-PCR and Northern blot analysis. There was a linear correlation (r(2) = 0.99, over 5 orders of magnitude) between microarray and quantitative real-time RT-PCR data. Microarray analysis of soybean has enormous potential not only for the discovery of new genes involved in tissue differentiation and function, but also to study the expression of previously characterised genes, gene networks and gene interactions in wild-type, mutant or transgenic; plants.
