Abstract
Although tremendous progress has been made in understanding nodulation of legumes and nitrogen fixation in legume nodules at a molecular level, there are still many unanswered questions in this field of research. The presentations in the following session are very diverse in their content, and deal with some of the important unanswered questions dealing with the biology of the rhizobia. Some of the questions which will be addressed in this plenary session, and which are the subject of active investigation in many laboratories, include:
-
1)
Why is the Rhizobium genome arranged in the way it is, and what is the role of all the various components of this genome ?
-
2)
Why is there so much reiteration of the Rhizobium genome ?
-
3)
Are there as yet undiscovered genes directly involved in nodulation or nitrogen fixation, whose presence has thus far been masked by the fact that these genes are reiterated?
-
4)
What are the mechanisms by which differentiation into bacteroids occurs, and what are the pathways that control this differentiation ?
