Ethylene in Lotus position for nodulation


Figure 1
Land-based biological N-fixation amounts to approx. 150 million tonnes per year, of which the symbiosis between legumes and rhizobia accounts for about 25 %. We have made great progress in understanding the biochemistry of N-fixation and in elucidating some aspects of the relationship between the plant host and bacterial symbiont. The tools of modern genetics have been very useful in this research, as is illustrated by the work of Lohar et al., at the Universities of Missouri, USA and Queensland, Australia (pp. 277–285). It is already known that ethylene inhibits nodule formation while ethylene inhibitors may promote it. To ‘dissect’ further the role of ethylene in nodule formation, the authors have transferred the Arabidopsis thaliana dominant etr-1-1 allele (which encodes a mutated non-functional . . .
