The acetohydroxyacid synthase large subunit (AHASL) gene of the RH44 lentil line was sequenced and found to contain a single mutation that gives rise to the A205V (using the Arabidopsis thaliana AHASL1 amino acid position nomenclature amino acid substitution in the AHASL protein, when compared to wild-type AHASL protein. Thus, a plant of the RH44 lentil line comprises a mutant AHASL gene that encodes an AHASL protein comprising a valine at the position that corresponds to amino acid 205 in the Arabidopsis thaliana AHASL1. In a wild-type AHASL protein, amino acid 205 is known to be alanine. The lentil plant of the present invention, the seeds of which have been deposited under the Patent Deposit Designation Number PTA-3270, comprise the amino acid sequence (SEQ ID NO: 1) of the mature herbicide-tolerant AHAS protein in RH44 lentil plant from amino acid residue 87 to amino acid 661. These amino acids correspond to amino acid residues 96-670 of Arabidopsis thaliana AHAS.
A proximate analysis was conducted to compare the RH44 lentil variety with existing registered wild type lentil varieties in order to determine if any significant differences in nutritional value existed (
