2013/8/9· The quaternary gene pool (GP-4) does not allow any transfer of DNA between the crop of interest or other organism by mating and ual recoination. In this case the process of transgenesis must be used to insert a DNA sequence from any biological or synthetic source known as a transgeneinto the crop plant of interest.
1996/6/1· Production of fertile transgenic maize plants by silicon carbide whisker-mediated transformation. The Plant Tissue culture protocols for gene transfer and …
Direct gene transfer into plant cells or protoplasts by the use of microinjection, electroporation or biolistic systems, or mediated by Agrobacteria is described in detail for various plant species, including relevant crops and cereals.
1.VECTOR MEDIATED GENE TRANSFER Agrobacterium mediated gene transfer Plant viral vectors Very efficient but limited to a selected group of plants Ineffective, hence not widely used 2.DIRECT OR VECTORLESS DNA TRANSFER
Plant transformation refers to the transfer and incorporation of engineered genes or plasmids into the plant genome. It is not only an essential biotechnological approach for in-depth research of plant growth, but also a promising tool for modern agriculture, specifically
organized plant tissues (Dekeyser et al., 1990), silicon carbide fiber-mediated DNA transfer into maize suspension cells (Kaeppler et al., 1990; Sood et al., 2011) and the microprojectile boardment or biolistic method (Klein et al., 1987

We review here the most recently developed technique for maize transformation which involves the vortexing of silicon carbide whiskers with maize cells in the presence of plasmid DNA. Fertile transgenic plants have been regenerated following whisker-mediated transformation which is compared with the alternatives described to date, namely protoplast uptake, particle boardment and

Silicon carbide fiber-mediated transformation of maize. DNA fragment containing the genetically engineered aad -1 gene cassette was released from plasmid pDAS1740 by FseI digestion and introduced into recipient maize line Hi-II through silicon carbide fiber (Whiskers)-mediated transformation ( 26 ).

synthase (CHS) gene for flower colour change [22]. Other methods include electroporation, chemical method and silicon carbide Whisker-mediated method. Chemical methods such as transfection by calcium phosphate has been used in plant gene
2019/8/8· For efficient transformation of plants and microalgae in the laboratory, a binary vector system based on the principles of T-DNA transfer is used in Agrobacterium mediated transformation. The T-DNA region is loed on a T-DNA binary vector while the Vir genes which express virulence proteins required for T-DNA transfer are contained in a separate Ti plasmid (Figure 2).
– Use silicon carbide fibers to punch holes through cultured plant cells – Silicon carbide fibers and cultured plant cells are added to a tube and vortexed vigorously – The mechanical force generated by the vortex drives the fibers into the cell
silicon carbide whiskers (Wang et al., 1995; Petolino et al., 2000), ultrasound (Joersbo and Brunstedt, 1990) or laser mediated gene-transfer (Weber et al., 1988) are of rather theoretical importance and were reviewed by Barcelo and Lazzeri (1998). n order to
