| 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. | | | |

| 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. | | | |
