Expression of lupine nodulin genes during root nodule development



Expression of lupine nodulin genes during root nodule development



Plant Science 55(2): 145-150



Seven lupin cDNA clones were used to study the expression of corresponding genes during nodule development by Northern blots analysis. They include six nodulin cDNAs; pLLb (lupin leghemoglobin), pLN 13, pLN 21-67, pLN 281, pLN 50, pLNGS (nodule form of glutamine synthetase GSn and root form of GS:pGS. The appearance of nodulin mRNAs during lupin nodule development showed that the nodulin sequences analysed represent a group of plant genes involved in the nitrogen fixation process rather than formation of nodule. This is based on the observation that they are activated at the time when the nodule has already been formed, prior to the onset of nitrogenase activity. The products of Lb, nodulin 21-67, the nodulin coded by pLN13 and the nodulin 281 genes appeared between 11 and 13 days after infection, whereas the nodulin coded by pLN50 and the nodule form of GS appeared 18 days after inoculation. Twenty-one days post-infection a dramatic increase in the transcription rates of all nodulin genes is observed. This phenomenon may be related to the onset of nitrogenase activity. The possible mechanism of two-step activation of nodulin genes is discussed.
