THE MEDICAGO TRUNCATULA LIN MUTANT: CAUGHT BY MAP-BASED CLONING, CHARACTERISED BY TRANSCRIPTOMICS

摘要

The Medicago truncatula lin (lumpy infections) mutant, which is defective in intermediate steps of nodule differentiation, has been identified previously as an EMS mutant of line A17 (Penmetsa and Cook, 2000). This mutant is characterized by a four-fold reduction in the number of infections, all of which arrest in the root epidermis, and by nodule primordia which initiate normally but fail to mature.
