The carotenoid biosynthetic pathway was genetically manipulated using the recombinant PAC (Phytoene synthase-2A-Carotene desaturase) gene in Korean soybean (Glycine max L. cv. Kwangan). The PAC gene was linked to either the β-conglycinin (β) or CaMV-35S (35S) promoter to generate β-PAC and 35S-PAC constructs, respectively. A total of 37 transgenic lines (19 for β-PAC and 18 for 35S-PAC) were ob...
ناقلین دوتایی مرسوم مبتنی بر pBI121 که هنوز به طور گستردهای در انتقال ژن به گیاه بهوسیله آگروباکتریوم استفاده میشوند، بهعلت عدم کارآیی گزینشگر کانامایسین، در برخی از گیاهان تکلپهای قابل استفاده نیستند در حالی که مقاومت به هیگرومایسین یک نشانگر گزینشی پرکاربرد و مهم در تراریختی برخی گیاهان بهویژه تکلپهایها به شمار میرود. از این رو در مطالعه حاضر، بهبود ناقل pBI121 برای تراریختی ...
ß-glucuronidase gene (GUS) driven by a constitutive 35S CaMV-promoter in Scots pine (Pinus sylvestris L.) buds were studied by the microprojectile DNA-delivery method. Buds were collected from 5-, 15and 50-year-old trees. In buds from all age groups the amount of transient expression was dependent on the season; the highest values were found in March, and values were lowest both at the beginnin...
In cell cultures of carrot (Daucus carota L.), somatic embryogenesis can be induced by transferring cells from a medium containing 2,4-dichlorophenoxyacetic acid (2,4-D) to one devoid of 2,4-D. Previous analysis of transgenic carrot cells containing the 5' non-coding sequence of the Ri plasmid rolC and a structural gene for bacterial beta-glucuronidase (uidA) has shown that the chimeric gene is...
In cell cultures of carrot (Daucus carota l.), somatic embryogenesis can be induced by transferring cells from a medium containing 2,4-dichlorophenoxyacetic acid (2,4-D) to one devoid of 2,4-D. Previous analysis of transgenic carrot cells containing the 5' noncoding sequence of the Ri plasmid rolC and a structural gene for bacterial 0-glucuronidase (uidA) has shown that the chimeric gene is act...
Pyramiding of <i>cry</i> toxins and methanol producing genes to increase insect resistance in cotton
The idea of enhanced methanol production from cell wall by pectin methyl esterase enzymes (PME) combined with expression cry genes Bacillus thuringiensis as a strategy to improve insect pest control in cotton is presented. We constructed cassette containing two (cry1Fa and Cry32Aa) pme genes, one Arabidopsis thaliana (AtPME), other Aspergillus. niger (AnPME) pCAMBIA1301 plant vector using CAMV-...
Developing transgenic resistance in monocotyledonous crops against pathogens remains a challenging area of research. Sugarcane mosaic virus (SCMV) is a serious pathogen of many monocotyledonous crops including sugarcane. The objective of present study was to analyze transgenic expression of hairpin RNA (hpRNA), targeting simultaneously CP (Coat Protein) and Hc-Pro (helper component-proteinase) ...
Hyoscyamine-6beta-hydroxylase (H6H; EC 1.14.11.11) catalyses oxidative reactions in the biosynthetic pathway leading from hyoscyamine to the more pharmaceutically valuable tropane alkaloid scopolamine. The h6h gene encoding H6H from Hyoscyamus niger was introduced, under the control of the CaMV 35S promoter, into non-hyoscyamine-producing Nicotiana tabacum and hyoscyamine-producing Hyoscyamus m...
• An effective transformation method is described for Medicago truncatula A17, verifying its suitability as a model legume for functional genomics. • Media and culture methods are detailed that yielded an average frequency of 35% for recovery of transgenic shoots from cotyledonary node explants and 39% for root induction and regeneration of entire plants from 419 phosphinothricinresistant shoot...
