Root 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...
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 کاملRhizobial infection is associated with the development of peripheral vasculature in nodules of Medicago truncatula.
Nodulation in legumes involves the coordination of epidermal infection by rhizobia with cell divisions in the underlying cortex. During nodulation, rhizobia are entrapped within curled root hairs to form an infection pocket. Transcellular tubes called infection threads then develop from the pocket and become colonized by rhizobia. The infection thread grows toward the developing nodule primordi...
متن کاملMALDI-mass spectrometric imaging for the investigation of metabolites in Medicago truncatula root nodules.
Most techniques used to study small molecules, such as pharmaceutical drugs or endogenous metabolites, employ tissue extracts which require the homogenization of the tissue of interest that could potentially cause changes in the metabolic pathways being studied(1). Mass spectrometric imaging (MSI) is a powerful analytical tool that can provide spatial information of analytes within intact slice...
متن کاملRegulatory Patterns of a Large Family of Defensin-Like Genes Expressed in Nodules of Medicago truncatula
Root nodules are the symbiotic organ of legumes that house nitrogen-fixing bacteria. Many genes are specifically induced in nodules during the interactions between the host plant and symbiotic rhizobia. Information regarding the regulation of expression for most of these genes is lacking. One of the largest gene families expressed in the nodules of the model legume Medicago truncatula is the no...
