Cell cultures of Linum album Kotschy ex Boiss. (Linaceae) showing high accumulation of the lignan podophyllotoxin (PTOX) were established. Enzymological studies revealed highest activities of phenylalanine ammonia-lyase, cinnamyl alcohol dehydrogenase, 4-hydroxycinnamate:CoA ligase and
UNASSIGNED
Elicitation of Linum album hairy roots by Piriformospora indica cell wall induced the target genes and specific metabolites in phenylpropanoid pathway and shifted the amino acid metabolism toward the phenolic compound production. Plants have evolved complex mechanisms to defend themselves
UNASSIGNED
Induction of tetraploidy was performed and podophyllotoxin production increased by upregulating the expression level and enzyme activity of genes related to its biosynthesis in tetraploid compared to diploid Linum album. Linum album is a valuable medicinal plant that produces antiviral
Linum album has been shown to accumulate anti-tumor podophyllotoxin (PTOX) and its related lignans. In the present study, we examined the effects of five fungal extracts on the production of lignans in L. album cell cultures. Fusarium graminearum extract induced the highest increase of PTOX
Feeding experiments with hairy root cultures of Linum album have established that the extracellular coniferaldehyde is a good precursor for production of two lignans: lariciresinol (LARI) and pinoresinol (PINO). The accumulation of the LARI, PINO, and podophyllotoxin (PTOX) in hairy roots were
Podophyllotoxin (PTOX) is a naturally occurring phenolic compound isolated as an active anti-tumor agent. The stimulatory influence of light on the formation of phenolic compounds has been reported, but the molecular mechanism underlying the effect of light on the expression of genes involved in
The accumulation of podophyllotoxin (PTOX) and 6-methoxypodophyllotoxin (6MPTOX) was enhanced about twofold in the suspension culture of Linum album line 2-5 aH following the addition of methyl jasmonate (MeJas) to the cultivation medium, reaching 7.69+/-1.45 mg/g dry weight and 1.11+/-0.09 mg/g dry
Hydrogen sulfide (H2S) has been recently found as an important signaling molecule especially in root system architecture of plants. The regulation of root formation through H2S has been reported in previous works; while the profiling of metabolites in response to H2S
Treatment of Linum album cell cultures with 10 μM salicylic acid (SA) for 3 days improved podophyllotoxin (PTOX) production up to 333 μg/g dry weight (DW): over three times that of the control cultures. qPCR analyses showed that in SA-treated cells, the expression of the genes coding for
