| Abstract | Nowadays, hairy root culture elicitation is an excellent platform with many advantages which make it an attractive system for using in plant biochemistry and molecular biology. Here, an efficient system for A. rhizogenes transformation in oriental poppy, Papaver orientale, was developed. Meanwhile, the expression level of various genes (COR, SalAT, SalR, T6ODM, CODM and Salsyn) in the morphinan pathway for response to methyl jasmonate (MJ) and salicylic acid (SA) at different time points (6, 12, 24 and 48 h) was examined. Afterwards, in vitro production of thebaine, morphine and codeine was investigated. The wild-type A. rhizogenes strain ATCC15834 was able to produce transformed roots with the highest frequency on the hypocotyl explant. Quantitative reverse-transcription PCR analysis showed that the expression of SalR, Salsyn, SalAT, T6ODM and CODM were significantly up-regulated with MJ treatment at 48 h. Moreover, the expression levels of Salsyn, T6ODM and CODM was up-regulated considerably in SA at 48 h treatment, while, the expression of SalR was down-regulated at 24 h. Furthermore, high-performance liquid chromatography analysis showed that MJ elicitation enhanced thebaine and morphine at 48 h by 2.63-fold (3.08 mg g$^{−1}$) and 6.18-fold (5.38 mg g$^{−1}$), respectively, and also codeine was increased at 24 h by 3.67-fold (2.57 mg g$^{−1}$). In addition, the accumulation of morphine and thebaine was increased by 4.22-fold (2.87 mg g$^{−1}$) and 2-fold (1.66 mg g$^{−1}$) in comparison with control treatment after SA treatment for 48 h. Our findings suggest that oriental poppy hairy roots can be used as a good source for producing commercial alkaloids. |

National Digital Library of India (NDLI) is a virtual repository of learning resources which is not just a repository with search/browse facilities but provides a host of services for the learner community. It is sponsored and mentored by Ministry of Education, Government of India, through its National Mission on Education through Information and Communication Technology (NMEICT). Filtered and federated searching is employed to facilitate focused searching so that learners can find the right resource with least effort and in minimum time. NDLI provides user group-specific services such as Examination Preparatory for School and College students and job aspirants. Services for Researchers and general learners are also provided. NDLI is designed to hold content of any language and provides interface support for 10 most widely used Indian languages. It is built to provide support for all academic levels including researchers and life-long learners, all disciplines, all popular forms of access devices and differently-abled learners. It is designed to enable people to learn and prepare from best practices from all over the world and to facilitate researchers to perform inter-linked exploration from multiple sources. It is developed, operated and maintained from Indian Institute of Technology Kharagpur.
