 Title    Cyclic AMP Is Not Involved as a Second Messenger in the Response of Soybean to Infection by Phytophthora megasperma f. sp. glycinea  
 Abstract    cAMP levels were monitored in soybean (Glycine max) infected with race 1 o f Phytophthora megasperma f. sp. glycinea and in soybean cell suspension cultures treated with a glucan elicitor from P. megasperma. While cAMP could be readily detected in soybean hypocotyls using a rad io ­ immunoassay, no correlation was observed between infection and cAMP levels. N o cAMP was detected in suspension cultured soybean cells. These results suggest that cAMP does not play a significant role in the plant's response to fungal attack, or the response o f suspension cultured cells to elicitor.

 Title    Hairs o f Soybean (Glycine max)  
 Abstract    Root hairs of soybeans (Glycine max), target cells for infection by Rhizobium japonicum accumulate iron more than 10-fold, cobalt more than 8-fold and calcium more than 7-fold compared to the other parts of the root system. In root hairs of wheat (Triticum aestivum) a much smaller accumulation of these elements was found. The symbiont of Glycine max, Rhizobium japonicum, is known to have a high requirement for iron, cobalt and calcium.

 Title    Root Hair Specific Proteins in Glycine max  
 Abstract    In root hairs from seedlings of Glycine max cultivars, isolated from the root system and com­ pared with the complete organ, specific soluble proteins have been found. By FPLC chromatogra­ phy and SDS gel electrophoresis root hair specific proteins with molecular weights of 13, 21, 34, 38 and 42 kDa were separated. Additionally, proteins with molecular weights of 12, 20, 69 and 74 kDa were significantly enriched in root hairs compared to roots without root hairs. By using CNBr activated Sepharose with antibodies against the root system without root hairs, the pres­ ence of root hair specific proteins was confirmed in extracts from isolated root hair cells. Enrich­ ment of Fe and Ca in some of the proteins from the root hairs is demonstrated. The present knowledge of the biochemical specificity of legume root hairs, the target cells of Rhizobium and Bradyrhizobium infection, is discussed.

 Title    The Role of Lipid Peroxidation in Aluminium Toxicity in Soybean Cell Suspension Cultures  
 Abstract    The primary reactions leading to Al toxicity in plant cells have not yet been elucidated. We used soybean (Glycine max [L.] Merr.) cell suspension cultures to address the question whether lipid peroxidation plays an important role in Al toxicity. Upon transfer to an Al-containing culture medium with a calculated Al3+ activity of 15 fiM soybean cells showed a distinct and longtime increase in lipid peroxidation within 4h. At the same time a drastic loss of cell viability was observed. Butylated hydroxyanisole (BHA) and /V,/V'-diphenyl-p-phenylenediamine (D PPD), two lipophilic antioxidants, were able to almost completely sup­ press lipid peroxidation in A l-treated cells at a concentration of 20 ^m. This effect was dose-dependent for DPPD and was observed at minimum concentrations of 1 -2 |.i m . When lipid peroxidation was suppressed by DPPD or BHA cell viability remained high even in the presence of toxic Al concentrations. These results suggest that Al-induced enhancement of lipid peroxidation is a decisive factor for Al toxicity in suspension cultured soybean cells.

 Title    Development of Discontinuous Size Classes of Nodules of Glycine max  
 Abstract    In order to characterize developmental stages o f nodules of Glycine max nitrogenase activity in the variety Caloria, infected with Rhizobium japonicum 61-A -101, was studied in atmospheres with 19 and 40% 0 2. By the enhancement effect at 40% 0 2 four stages o f nodule development could be separated. Nitrogenase activity depends also among other things on nodule size. 3 -4 maxima in nodule number and nodule weight were found by fractionating nodules in 12 different size classes. Discontinuous size distribution was found with medium aged and old effective nodules. Nodule number (20 to 30) o f effective nodules per plant remains constant. Ineffective nodules remain far smaller than the effective ones, the number increases to more than 140 per plant and only one discontinuous size classe was observed. Bacteroids and plant cytoplasm from nodules of some size classes are characterized by their leghaemoglobin content and specific activity of enzymes o f nitrogen metabolism such as aspartate aminotransferase (E.C., glutamate dehydrogenase (E.C. and alanine de­ hydrogenase (E.C. The data in the various size classes are similar both in the bacteroids and the plant cytoplasm, however, leghaemoglobin content and specific activity o f the bacterial enzyme alanine dehydrogenase are positively correlated with the increasing nodule size.

 Title    Soybean Root Response to Symbiotic Infection Glyceollin I Accumulation in an Ineffective Type of Soybean Nodules with an Early Loss of the Peribacteroid Membrane  
 Abstract    A glyceollin I accumulation o f about 6000 pm ol • mg dry weight-, a tenfold increase above control root tissue, was found in one type o f nodule from Glycine m ax which had been infected with a fix ~ strain (61-A-24) o f Rhizobium japonicum . In nodules infected with one other ineffective (ßx~) strain o f Rhizobium japonicum (RH 31-Marburg) or with two f i x + strains o f Rhizobium japonicum (61 -A -101 and U SD A 110) no increase in glyceollin I concentrations above control values was found at either 20 d or 34 d after infection. N odules infected with Rhizobium japonicum 61-A-24 are distinguished by an early loss o f the peribacteroid membrane in the infected host cell, whilst the bacteroids them selves remain stable.
