Rosmarinic acid and its derivatives: biotechnology and applications
Rosmarinic acid (RA) is one of the first secondary metabolites produced in plant cell cultures in extremely high yields, up to 19% of the cell dry weight. More complex derivatives of RA, such asExpand

Effect of salicylic acid, methyl jasmonate, ethephon and cantharidin on anthraquinone production by Rubia cordifolia callus cultures transformed with the rolB and rolC genes.
It has been suggested that the rol genes of Agrobacterium rhizogenes could play an essential role in the activation of secondary metabolite production in plant transformed cultures. This studyExpand

Individual and combined effects of the rolA, B, and C genes on anthraquinone production in Rubia cordifolia transformed calli
It is known that the rolA, rolB, and rolC genes of Agrobacterium rhizogenes T‐DNA affect processes of plant development and activate the synthesis of secondary metabolites in transformed plant cells.Expand

Recent advances in the understanding of Agrobacterium rhizogenes-derived genes and their effects on stress resistance and plant metabolism.
It is commonly accepted that the plant pathogens Agrobacterium rhizogenes and Agrobacterium tumefaciens, acting via their T-DNA oncogenes, disturb hormone metabolism or hormone perception pathways inExpand

The rolB gene-induced overproduction of resveratrol in Vitis amurensis transformed cells.
Resveratrol is a stilbene, which prevents carcinogenesis at stages of tumor initiation, promotion and progression. In the present investigation, we developed cell cultures of wild-growing grapeExpand

The impact of plant rolC oncogene on ginsenoside production by ginseng hairy root cultures
Plasmid constructions containing rolA, rolB and rolC genes, isolated earlier from the TL-DNA of Agrobacterium rhizogenes were used to transform a cell culture (strain 1c) of Panax ginseng. The levelsExpand

Phenylalanine ammonia-lyase and stilbene synthase gene expression in rolB transgenic cell cultures of Vitis amurensis
Transformation of Vitis amurensis callus culture by the plant oncogene rolB of Agrobacterium rhizogenes results in high (up to 3.15% dry wt.) levels of resveratrol in the transformed culture. TheExpand

Occurrence of a Silicatein Gene in Glass Sponges (Hexactinellida: Porifera)
Silicatein genes are involved in spicule formation in demosponges (Demospongiae: Porifera). However, numerous attempts to isolate silicatein genes from glass sponges (Hexactinellida: Porifera)Expand

The rolB Gene Suppresses Reactive Oxygen Species in Transformed Plant Cells through the Sustained Activation of Antioxidant Defense1[C][W][OA]
The rolB (for rooting locus of Agrobacterium rhizogenes) oncogene has previously been identified as a key player in the formation of hairy roots during the plant-A. rhizogenes interaction. In thisExpand
