ABSTRACT- In order to produce transgenic rice lines lacking selectable marker gene, biolistic co-transformation technique using gold nanoparticles was adopted. In the first step, the efficiency of different sizes of gold particles was evaluated. The results showed that the efficiency of the nanoparticles in the transformation was comparable to that of the micro particles. Subsequently, two sepa...

abstract lettuce (lactuca sativa l.) is a major leafy vegetable and belongs to the asteraceae family (compositae). the genetic manipulation of lettuce requires a reliable and efficient regeneration method. since lettuce is a suitable bioreactor for production of recombinant proteins especially edible vaccines. this study was conducted to identify an appropriate method for lettuce gene transform...

The introduction of exogenous DNA sequences into cultured cells is a cornerstone in the study of mammalian gene expression. For most cell types, the efficiency of stable gene transfer is usually quite low, which mandates the use of selectable markers to isolate a population of transfected cells with the desired phenotype. In simple gene expression experiments, only one type of selectable marker...

We developed an efficient electrotransformation system for the pathogenic fungus Histoplasma capsulatum and used it to examine the effects of features of the transforming DNA on transformation efficiency and fate of the transforming DNA and to demonstrate fungal expression of two recombinant Escherichia coli genes, hph and lacZ. Linearized DNA and plasmids containing Histoplasma telomeric seque...

Transcription of the Neurospora crassa gene con-10 is induced during conidiation and following exposure of vegetative mycelia to light, but light activation is transient due to photoadaptation. We describe mutational analyses of photoadaptation using a N. crassa strain bearing a translational fusion of con-10, including its regulatory region, to a selectable bacterial gene conferring hygromycin...

Present investigation was carried out to identify DNA polymorphism of IL-2Rγ and ChB6 genes. Sixty five birds belonging to the indigenous chicken of Himachal Pradesh were utilized. Good quality DNA samples were subjected to PCR-RFLP analysis using chicken specific primers. Overnight restriction enzyme digestion was carried out at 37°C with IU Hph I and Pvu II for IL-2Rγ and ChB6 genes, respecti...

A mutant screen was conducted in Arabidopsis that was based on deregulated expression of auxin-responsive transgenes. Two different tightly regulated (i.e., very low expression in the absence of auxin treatment and very high expression after exogenous auxin treatment) auxin-responsive promoters were used to drive the expression of both a beta-glucuronidase (GUS) reporter gene and a hygromycin p...

The completion of genome-sequencing projects for a number of fungi set the stage for detailed investigations of proteins. We report the generation of versatile expression vectors for detection and isolation of proteins and protein complexes in the filamentous fungus Neurospora crassa. The vectors, which can be adapted for other fungi, contain C- or N-terminal FLAG, HA, Myc, GFP, or HAT-FLAG epi...
