Use of a Subtractive Hybridization Approach to Identify New Medicago truncatula Genes Induced During Root Nodule Development
Abstract
We report the identification of new molecular markers associated with different stages of Rhizobium-induced nodule development in the legume Medicago truncatula. A cDNA library was constructed from pre-nitrogen-fixing M. Truncatula nodules, and differentially screened with a polymerase chain reaction-amplified subtracted probe. Twenty-nine new families of nodulin cDNA clones, designated MtN1 to MtN29, were thus identified in addition to clones for several known nodulins. All MtN genes were shown by Northern (RNA) hybridization analysis to be induced during nodulation, some of them well before nodule emergence. The MtN genes were classified into three groups depending on their expression kinetics. The expression of three MtN genes showed a limited induction by Nod factors purified from Rhizobium meliloti. Homologies with a variety of proteins were found for the deduced amino acid sequences of 10 of the MtN genes.

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
