A suppressor screen of Medicago truncatula mtpt4-1 for gene mutations in the regulation of arbuscule degradation
We are screening mutagenized Medicago truncatula mtpt4-1 mutants for suppressors of the mtpt4-1 phenotype. The pt4-1 mutant varies from the wild type in that it speeds up the expiration of arbuscules in root cells. The wild type allows for the natural development and death of arbuscules. The found mutants will latter be used in identifying the genes responsible for arbuscule regulation.
