Differential expression of the TFIIIA regulatory pathway in response to salt stress between Medicago truncatula genotypes.

abstract：:At least two hydroxypyruvate reductases (HPRs), differing in specificity for NAD(P)H and (presumably) utilizing glyoxylate as a secondary substrate, were identified by fractionation of crude maize leaf extracts with ammonium sulfate. The NADH-preferring enzyme, which most probably represented peroxisomal HPR, was prec...
