Plant cells engage in mutualistic and parasitic endosymbioses with a wide variety of
microoganisms, ranging from Gram-negative (Rhizobium, Nostoc) and Gram-positive …

Rhizobium nodulation (Nod) factors are lipo-chitooligosaccharides that act as symbiotic
signals, eliciting several key developmental responses in the roots of legume hosts. Using …

Intracellular bacteria have been found previously in one isolate of the arbuscular
mycorrhizal (AM) fungus Gigaspora margarita BEG 34. In this study, we extended our …

The role of the Lotus japonicus LjSym4 gene during the symbiotic interaction with
Mesorhizobium loti and arbuscular mycorrhizal (AM) fungi was analyzed with two mutant …

Nitrogen is the most important nutrient input required for rice production. A major goal of
biological nitrogen fixation (BNF) research has been to extend the nitrogen-fixing capacity to …

A long-standing goal of biological nitrogen fixation research has been to extend the nitrogen-
fixing rhizobial symbioses of legumes to nonnodulated cereal plants such as rice. To …

Generally, root hairs emerge at the apical end of some epidermal cells, and elongate by
polar growth of the tip (Cormack 1962; see Chapters 1 to 3 this volume). Young, elongating …

The LlPRP2 gene coding for a proline-rich protein shows a high level of similarity to, as well
as significant differences from the family of ENOD2 nodule-specific genes. Several …

Until recently little was known about the identity of the genes expressed in the arbuscules of
mycorrhizas, due in part to problems associated with cloning genes from the tissues of an …

The study of the interaction of plants with diazotrophic bacteria has clearly shown that it is
only in intercellular, endosymbiotic interactions that significant amounts of fixed nitrogen are …
