Respiration in support of N 2 fixation by rhizobia in legume root nodules depends on an adequate supply of O 2 , but excessive O 2 can damage nitrogenase, the key enzyme. The movement of O 2 into and within the nodule is driven by gradients in the concentration of O 2 or in the oxygenation of the...
In plants, the nuclear envelope (NE) is one of the least characterized cellular structures. In particular, little is known about its dynamics during the cell cycle. This is due to the absence of specific markers for in vivo studies. To generate such an in vivo marker, the suitability of the human...
