AbstractHairy root culture system is a valuable tool to study the characteristics of gene expression, gene function, root biology, biochemical properties and biosynthesis pathways of secondary metabolites. In the present study, hairy roots were established in Anise hyssop (Agastache foeniculum) via Agrobacterium rhizogenes. Three strains of Agrobacterium rhizogenes (A4, A7 and 9435), were used for induction of hairy roots in four various explants (hypocotyl, cotyledon, one-month-old leaf and five-month-old leaf) of Anise hyssop. The highest frequency of transformation was achieved using A4 strain in one-month-old leaves (51.1%). The transgenic states of hairy root lines were confirmed by PCR (Polymerase chain reaction) method. High performance liquid chromatography analysis revealed that the production of rosmarinic acid (RA) in transformed roots of A. foeniculum was almost 4-fold higher than that of the non-transformed roots. In a separate experiment, hairy roots obtained from one-month-old leaves inoculated with A4 strain, were grown in liquid medium and the effects of different concentrations of salicylic acid (0.0, 0.01, 0.1 and 1 mM) and chitosan (0, 50, 100 and 150 mg L−1) (as elicitor) and sucrose (20, 30, 40 and 50 g L−1) on the growth of hairy roots were evaluated. The results showed that, 30 g L−1 sucrose and 100 mg L−1 chitosan increased the biomass of hairy root cultures and application of salicylic acid reduced the growth of hairy roots compared with control roots.

Abstract Leaves and internodes from Stevia rebaudiana Bertoni plants growing in different conditions were used for transformation with two strains of Agrobacterium rhizogenes: ATCC 15384 and LBA 9402. Hairy roots formation was observed and the percentage of the transformed explants depended on the type of explant, time of inoculation and inoculum concentration. Inoculation of explants from ex vitro and in vitro plants with LBA 9402 strain led to higher efficiency of transformation than inoculation with ATCC 15384 strain. Growth rate of hairy roots in liquid culture was assessed under light and dark conditions. It was found that the growth of hairy roots decreased significantly under light conditions. Transformation of hairy roots growing in different culture conditions was confirmed at the molecular level using PCR method with primers constructed against rolB and rolC genes from A. rhizogenes.

Background: Hairy root culture has been widely used in the production of metabolites in dicotyledons, and a large number of food crops and medicinal plants in monocotyledons need to be developed, but there are many difficulties in the induction of hairy roots in monocotyledons. The purpose of this paper is to introduce the inducing methods, influencing factors and application of hairy roots in monocotyledons, and to promote the development of hairy root system in monocotyledons. Methods: The mechanism of action of Agrobacterium rhizogenes and the current situation of hairy root induction, induction methods and influencing factors of monocotyledons were summarized so as to provide convenience for efficient acquisition of hairy root of monocotyledons. Results: Monocotyledons are not easy to produce phenols, cells are prone to lignification, adverse differentiation and selective response to Agrobacterium rhizogenes strains. It is proposed that before induction, plant varieties and explants should be selected, and different infection strains should be screened. In the process of hairy root induction, exogenous inducers such as acetosyringone can be added. Although these factors can provide some help for the induction of hairy roots in monocotyledons, we still need to pay attention to the disadvantages of monocotyledons from dicotyledons at the cellular level. Conclusion: A large number of food crops and medicinal plants are monocotyledons. Hairy root culture can be used to help the breeding and production of medicinal substances. Therefore, it is necessary to pay attention to the selection of varieties and explants, the selection of Agrobacterium rhizogenes and the addition of acetosyringone in the process of hairy root induction so as to improve the production efficiency and facilitate the development and utilization of monocotyledons.

Senna Alata

Hairy roots of Senna alata transformed with Agrobacterium rhizogenes, strain ATCC 15834 were induced and grown in half-strength Murashige and Skoog (MS) medium. Effects of sucrose contents and hormones on the growth and sennosides A, B production were investigated. Hairy roots cultured on hormone-free half-strength MS medium containing 5% sucrose under dark condition mostly stimulated the growth of hairy roots and increased the content of sennosides A and B yielding (169 ± 4) and (34 ± 3) μg g-1 dry wt, respectively.
