DNA microarray analysis of primary metabolism in Fe-deficient , roots and shootsidual gene sequences. . seedlings were grown 1, 3, and 7 d in the absence of Fe, and gene expression in roots and shoots was investigated. The data were normalized with regard to radioactivity and the amount of DNA bound to the hybridization membrane. Several distinct changes in the expression of ge

Plastiden bei der arbuskulären Mykorrhizasymbiosemolecular building blocks for symbiotic structures on the other. These metabolic tasks correlate with a strong proliferation and structural changes of the organelles. Future work will address the molecular factors responsible for these metabolic and structural changes.

Kultivierungsunabhängige Analyse des Einflusses von Chlorpyrifos auf die mikrobielle Lebensgemeinschconcentrations seems to be without influence on the majority of bacteria. But in contrast to previous results we found by SSCP-fingerprinting that few bacteria among . and . influenced over few months. The sequence behind the increased bands 1 and 2 in two .fingerprints (Abb. 1) matched . with a sim

To invesitigate a possible effect of the nitrogen form on tiller number, a nutrient solution experiment was set up, in which summer barley was grown in a growth chamber with supply of nitrate, urea or ammonium, or of nitrate and urea at different molar ratios.
