    Biotechnological approaches for genetic improvement of fenugreek (Trigonella foenum-graceum L.)
    (Springer Singapore, 2018) Aasim M.; Baloch F.S.; Bakhsh A.; Sameeullah M.; Khawar K.M.
    Abstract Fenugreek (Trigonella foenum-graecum L.) is one of the important medicinal plants of ancient medicinal systems due to its high nutraceutical and pharmaceutical properties. Seeds and leaves of Fenugreek contain phytochemicals like diosgenin and trigonelline. It is a cultivated plant of the modern world for medicinal uses, an edible vegetable, and a forage plant. Advancement in industrial and biotechnological techniques for the isolation of phytochemicals increase the demand of Fenugreek, and its breeding programs are based on improving the secondary metabolites compared to other uses. Recent advancement in modern biotechnological approaches enables researchers to develop elite cultivars of desired traits in a short time. Application of modern techniques like artificial mutations under in vitro conditions, characterization using molecular markers, and development of successful plant tissue culture techniques, genetic transformation techniques, and functional genomics studies have significant potential to improve Fenugreek traits. The study highlights the application of biotechnological approaches used for the development of elite Fenugreek traits for the researchers for future breeding programs. Furthermore, the research gap and areas to improve research have been highlighted in this present study. © Springer Nature Singapore Pte Ltd. 2018.

    Development of transgenic tobacco lines with pyramided insect resistant genes
    (Scientific and Technical Research Council of Turkey, 2018) Bakhsh A.; Dınç T.; Hussain T.; Demırel U.; Aasim M.; Çalişkan M.E.
    Insect pests are among the major constraints rendering drastic decreases in crop yield. The expression of stacked insecticidal genes in crops can lead to resistance durability and can delay the development of resistance in target insect pests. The present study was designed to introduce an insect resistance trait in locally cultivated Turkish tobacco cultivars (Basma and Nail) with pyramided insecticidal genes. Agrobacterium strain LBA4404 harboring plasmid pKGH4 with cry1Ac and cry2A genes under the control of 35S promoter was used to infect leaf discs of both cultivars; plasmid also contained uidA within the T-DNA region for earlier screening of putative transformants. The overall transformation efficiency was calculated as 30.7% and 18.8% in Basma and Nail, respectively. PCR results confirmed the integration of cry1Ac, cry2A, uidA, and nptII genes in 40 plants of Basma and 16 plants of Nail. ELISA results showed variation in expression of cry1Ac protein among transgenic plants varying from 0.017 to 0.607 µg/g of fresh tissue. Bioassay results with potato tuber moth (Phthorimea operculella Zeller) showed significant mortality of the targeted pest on primary transformants. Furthermore, T1 transgenic progeny exhibited the inheritance of T-DNA in Mendelian as well as non-Mendelian fashion. The results revealed that lines can serve as a source of germplasm in tobacco breeding programs. © TÜBİTAK.
