Induced mutations in the TI1 gene encoding a major double-headed protease inhibitor in Pisum sativum L. can reduce significantly the inhibition of target enzymes
BAP GEAPSI; International audience; Trypsin / chymotrypsin inhibitors in the seeds of many legume crop species are regarded as antinutritional proteins often leading to a requirement for heat-treatment of seed products prior to their use in feed. A TILLING resource developed in Pisum sativum L. (pea) was exploited to identify mutants in the major seed-expressed trypsin / chymotrypsin inhibitor gene, TI1, where the inhibition of either or both of the target enzymes may be reduced. Three lines with missense mutations in TI1, predicted to affect activity through alteration of (a) a conserved cysteine residue, (b) the P1′ serine within the active site of the chymotrypsin inhibitory domain or (c…
