environmental stresses affect plant growth and cause losses worth hundreds of million dollars of agricultural industry each year. many genes induced in response to environmental stresses. the dreb1a gene is a stress-inducible transcription factor that its overexpression increased tolerance to environmental stress in transgenic plants. dna was extracted from arabidopsis thaliana var. col.0 plant...

Panax ginseng is a valuable medicinal herb of the Araliaceae family with various pharmacological activities. The Trihelix transcription factors involved in growth and secondary metabolic processes plants, but no studies have been reported on involvement genes ginseng. In this study, weighted co-expression network analysis, correlation analysis between PgGTs ginsenosides key enzyme genes, intera...

BACKGROUND Hepatitis C virus (HCV) is major cause of liver cirrhosis in humans. HCV capsid (core) protein (HCVcp) is a highly demanded antigen for various diagnostic, immunization and pathogenesis studies. Plants are considered as an expression system for producing safe and inexpensive biopharmaceutical proteins. Although invention of transgenic (stable) tobacco plants expressing HCVcp with pro...

Dehydrin is known to have an important role in plant response and adaptation abiotic stresses including drought high salinity. Previous research reported the isolation of full-length coding sequence (CDS) DHN1 from sugarcane var. PSJT 941, it shares a homology with DHN genes sorghum other varieties. In this study, CDS was cloned under constitutive CaMV35S promoter transformed into calli mediate...

expansin proteins are a type of cell-wall loosening proteins which able to cell wall expansion in ph-dependent manure without hydrolyze of main cell wall structures. the arabidopsis expa1 exhibit guard cell specific expression and trigger the stomatal movements. the objectives of this study were to transfer the atexpa1 gene into tobacco plants and evaluate their phonotypic effects on transforme...

plant growth is a result of cell division and cell enlargement. expansins are proteins that mediate long-term extension of isolated cell walls and they play a variety of roles in plant cells. in this study the atexpb2 gene was over-expressed in arabidopsis thaliana. the gene was isolated from genomics dna of arabidopsis and cloned into mediated vectors; pgemt and pbi121 vectors. transformation ...
