An efficient protocol for hairy root induction in Berberis aristata DC. was established using two different strains of Agrobacterium rhizogenes, MTCC 532 and 2364 from IMTECH (Institute of Microbial Technology), Chandigarh, India. The strain 532 was more effective than strain 2364 in hairy root induction and in vitro grown callus (61.11 ± 1.60 % transformation frequency) was found to be suitabl...

Agrobacterium rhizogenes infects plants to induce hairy roots. It is classified into four different types such as agropine, mannopine, cucumopine and mikimopine. A.rhizogenes K599, also known as NCPPB2659, is a representative strain of the cucumopine type. In this review, we discussed the functions of 11 genes on the T-DNA of Ri plasmid pRi2659 in K599. We summarized the infectivity of K599 on ...

Root-knot nematodes (RKNs) infect many annual and perennial crops and are the most devastating soil-born pests in vineyards. To develop a biotech-based solution for controlling RKNs in grapes, we evaluated the efficacy of plant-derived RNA interference (RNAi) silencing of a conserved RKN effector gene, 16D10, for nematode resistance in transgenic grape hairy roots. Two hairpin-based silencing c...

Dopamine is one of the important medications of Portulaca oleracea L. To optimize the production of dopamine, one of the methods is the identification and engineering of metabolite pathways. To investigate the tyrosine decarboxylase (TDC) and tyrosinase, which seem to be the most important genes in dopamine synthesis pathway, hairy roots were produced from Portulaca oleracea using Agrobacterium...

Hairy root culture is a potential alternative to conventional mammalian cell culture to produce recombinant proteins due to its ease in protein recovery, low costs and absence of potentially human pathogenic contaminants. The current study focussed to develop a new platform of a hairy root culture system from Nicotiana tabacum for the production of recombinant human EPO (rhEPO), which is regula...

A lysine histidine transporter (LHT) cDNA was isolated and characterized from the roots of Panax ginseng, designated PgLHT. The cDNA is 1,865 bp with an open reading frame that codes for a protein with 449 amino acids and a calculated molecular mass of 50.6 kDa with a predicted isoelectric point of 8.87. Hydropathy analysis shows that PgLHT is an integral membrane protein with 9 putative membra...
