Factors involved in root formation in Medicago truncatula.
The fact that auxin induces root formation has been known for more than half a century. However, despite the recent progress in this field, neither the molecular processes in which the auxin-responsive genes leading to root formation nor the interactions between phytohormones and other bioactive molecules during the commitment phase of root formation are well understood. Here the effect of biom...
متن کاملRNA interference identifies a calcium-dependent protein kinase involved in Medicago truncatula root development.
Changes in cellular or subcellular Ca2+ concentrations play essential roles in plant development and in the responses of plants to their environment. However, the mechanisms through which Ca2+ acts, the downstream signaling components, as well as the relationships among the various Ca2+-dependent processes remain largely unknown. Using an RNA interference-based screen for gene function in Medic...
متن کاملTranscription Reprogramming during Root Nodule Development in Medicago truncatula
Many genes which are associated with root nodule development and activity in the model legume Medicago truncatula have been described. However information on precise stages of activation of these genes and their corresponding transcriptional regulators is often lacking. Whether these regulators are shared with other plant developmental programs also remains an open question. Here detailed micro...
متن کاملMedicago truncatula
Immanuel Kant noted this approach would not be suitable for understanding complex systems such as an organism. He said there would never be a " Newton of the blade of grass " : because the blade of grass is more than the sum of its parts, complete knowledge of the parts list will not necessarily be predictive of the behavior of the whole. Fortunately, we don't have to resort to a vitalistic exp...
متن کاملRoot developmental programs shape the Medicago truncatula nodule meristem.
Nodules on the roots of legume plants host nitrogen-fixing Rhizobium bacteria. Several lines of evidence indicate that nodules are evolutionarily related to roots. We determined whether developmental control of the Medicago truncatula nodule meristem bears resemblance to that in root meristems through analyses of root meristem-expressed PLETHORA genes. In nodules, MtPLETHORA 1 and 2 are prefere...
