• Biological nitrogen fixation
• genetic manipulation
• non-nodular and nodular symbiosis
• nif genes
• rice

Current knowledge of the genetics of biological nitrogen fixation (BNF) and recent advances of the knowledge of the natural diversity among the diazotrophs kindled interest among concerned scientists in assembling BNF system in rice plant to fix its own nitrogen. Though the task is complex, emerging knowledge of functional genomics and new biotechnological tools opened up a number of research endeavours. Advanced laboratories around the globe in rice research are pursuing studies mainly in three well-defined approaches, viz. forced association between rice and diazotrophs, i.e. non-nodular symbiosis; forcing nodulation in rice plant to establish nodular symbiosis and constructing functional nitrogenase system in rice plants through transferring nif genes. Frontier areas of these research endeavours have been reviewed in this article.
