Cloned (Comment) Organism
quantitative RT-PCR enzyme expression analysis, the gene expression levels of COR in tetraploids are not remarkably changed compared to diploid plants. In the roots both genes COR and CODM, downstream of thebaine in the alkaloid pathway, are downregulated in tetraploids Papaver bracteatum

Protein Variants Comment Organism
additional information the in vitro tetraploidy induction through methyl jasmonate (MeJA) elicitation causes a significantly increased expression of norcoclaurine synthase (NCS) and salutaridinol (SAT), and a significantly decreased expression of berberine bridge enzyme (BBE) in the leaves. In the root tissues, the BBE, NCS, and SAT show an increased expression in tetraploid plants, while codeinone reductase (COR) shows a decreased expression. A similar alteration pattern is found in mixoploid plants when compared to their diploid counterparts. MeJA at concentrations of 0.1 and 0.5 mM causes a remarkable increase in the thebaine content in the roots of treated plants, where the highest thebaine content is identified in plants elicited with 0.5 mM MeJA. Elicitation treatment causes a substantial increase in the expression of NCS and SAT in the leaves, while it has no major effect on BBE, codeine 3-O-demethylase (CODM) and COR. Expression analysis in the roots shows that MeJA causes a significant increase in the expression of only BBE and NCS, while expression of other studied genes remains unchanged Papaver bracteatum

Expression

Organism Comment Expression
Papaver bracteatum methyl jasmonate treatment suppresses expression of codeinone reductase (COR) in roots of in tetraploid and mixoploid Papaver bracteatum plants, while the expression level of COR in leaves is unaffected by up to 0.5 mM methyl jasmonate down

General Information

General Information Comment Organism
metabolism the enzyme is involved in the downstream metabolization of thebaine, benzylisoquinoline alkaloids pathway, overview. In the roots both genes COR and CODM, downstream of thebaine in the alkaloid pathway, are downregulated in tetraploids. The gene expression levels of COR in tetraploids are not remarkably changed compared to diploid plants. Via methyljasmonate treatment, gene expression of genes upstream of thebaine is upregulated while the genes downstream of thebaine are partly downregulated in tetraploids Papaver bracteatum
