agrobacterium-mediated transformation of pomegranate (punica granatum l.) ‘yousef khani’ using the gus reporter gene
نویسندگان
چکیده
in this study, an efficient agrobacterium-mediated transformation method was developed forpomegranate (punica granatum l.), a difficult-to-transform plant. in vitro shoot segments wereinoculated with agrobacterium tumefaciens strain lba4404 harboring the binary vectorpbi121 carrying the neomycin phosphotransferase (nptii) gene as a selectable marker and β-glucuronidase (gus) gene as a reporter. after 28 d in wpm selection medium containing 50 mgl-1 kanamycin, 59 new shoots proliferated. gus analysis was performed on these putativetransgenic shoots, of which 32 stained positive. positive staining shoots were cut and culturedin selection medium for 2 subsequent subcultures until final gus analysis. after three months ofthe selection period, 6 putative transgenic shoots were obtained. presence of the gus and nptiigenes was confirmed by polymerase chain reaction. southern blot analysis confirmed that tdnawas stably integrated into the genome of three out of six pcr-positive plants. thetransgenic plants were rooted and successfully acclimatized.

متن کاملThe role of pomegranate (Punica granatum L.) in colon cancer.
Colon cancer is one of the major causes of cancer-related death in the Western world. Although cytotoxic chemotherapeutic agents are available to treat the disease, these agents become ineffective as the disease advances to an invasive state. An alternative but viable approach to reduce the incidence of this deadly disease is then, to increase the dietary intake of relatively non-toxic fruits a...

متن کاملINVITED REVIEW Biotechnological advances in pomegranate (Punica granatum L.)
Pomegranate (Punica granatum L.) is known for its nutritional, medicinal, and ornamental importance. It is conventionally propagated by hardwood and softwood cuttings, but about 1 yr is needed before the rooted cuttings can be transplanted to the field. Propagation by seed is undesirable as populations are heterozygous and seed propagation leads to wide variations in tree and fruit characterist...

متن کاملSeed Characterisation of Five New Pomegranate (punica Granatum L.) Varieties
This study evaluated the production of five new pomegranate varieties (MAP 14 , AKP15 , DMWP 2, NMRP 7 and JBP 1), being all indigenous to Southeastern India where the species shows high variability. A morphological and organoleptic characterisation of the edible portion of the seeds were investigated. Some chemical characteristics of the juice, including total soluble solids, pH, acidity and m...
