SYSTEMATIC NAME
IUBMB Comments
vestitone:NADP+ oxidoreductase
In the reverse reaction, a 2'-hydroxyisoflavone is reduced to an isoflavanone; 2'-hydroxypseudobaptigenin also acts. Involved in the biosynthesis of the pterocarpin phytoalexins medicarpin and maackiain.
transgenic rice lines overexpressing the OsIRL gene under an abscisic acid inducible promoter are tolerant against methyl viologen (MV) and glucose/glucose oxidase-induced stress in rice leave and suspension-cultured cells
FcIRL belongs to the class of pinoresinol-lariciresinol reductase, PRL, functioning in the biosynthesis of 8,8'-linked lignans, with function in catalyzing reduction of pinoresinol and lariciresinol into secoisolariciresinol, and medicinal secondary metabolism and resistance in Fagopyrum cymosum
CaIRL protein is a new member of the PIP family of NADPH-dependent reductases, enzymes are involved in the biosynthesis of plant defense metabolites such as lignans and isoflavonoids

LITERATURE
After embedding of seeds in agar containing 2',7',-dichlorofluorescin, the H2O2 is highly stimulated in the elongation region compared with the root apex. The OsIRL mRNA expression level in 3-day-old roots is weakly expressed in the apex region, it shows an increment accompanying the increase in H2O2 concentration, results indicate that the expression level and localization of OsIRL is associated with H2O2 accumulation.; OsIRL gene and protein are downregulated in young seedling roots treated with diphenyleneiodonium, known quencher of reactive oxygen species, but to a lesser extent when compared with glutathione treatment in roots; OsIRL gene and protein are downregulated in young seedling roots treated with reduced glutathione, a known quencher of reactive oxygen species, in roots of 3 day-old young seedlings grown on glutathione, reactive oxygen species levels are significantly decreased by approximately 50% in the presence of 1 mM glutathione compared with untreated controls; OsIRL gene and protein are shown to be downregulated in young seedling roots treated with reduced glutathione and diphenyleneiodonium
increased expression of GbIRL1 is detected when the seedlings are treated with ultraviolet-B, 5-aminolevulinic acid, wounding and ethephon, abscisic acid, salicylic acid
OsIRL transcript level in rice suspension-cultured cells is found to be by hydrogen peroxide, ferric chloride, methyl viologen and glucose/glucose oxidase; the expression of OsIRL is slightly increased after treatment 0.02 mM abscisic acid in wild-type calli, suggesting a possible reason for glucose/glucose oxidase stress resistance; the OsIRL transcript level in rice suspension-cultured cells is induced by FeCl3 within 4 h after treatment, but down-regulated when co-treated with glutathione; the OsIRL transcript level in rice suspension-cultured cells is induced by glucose/glucose oxidase within 4 h after treatment, but down-regulated when co-treated with glutathione; the OsIRL transcript level in rice suspension-cultured cells is induced by methyl viologen within 4 h after treatment, but down-regulated when co-treated with glutathione; the OsIRL transcript level in rice suspension-cultured cells is induced by the oxidant H2O2, but down-regulated when co-treated with glutathione
the full-length version of the CaIRL promoter directs a reporter gene expression that is stimulated by mechanical injury as the expression from the native CaIRL gene; the promoter of a gene encoding an isoflavone reductase-like protein in coffee drives a stress-responsive expression in leaves; transcript level is markedly increased in response to fungal infection and mechanical injury, a rapid and marked increase in CaIRL expression is also observed following mechanical injury of the leaves (75fold after 4 h treatment), this induction is followed by a progressive decrease in transcript accumulation at 8 and 12 h post injury, the activation of CaIRL expression by mechanical injury is faster than that observed in response to fungal inoculation
