GV3101 (pSoup) competent cells are widely used in plant biotechnology for Agrobacterium-mediated transformation. These cells are particularly effective for transferring genetic material into plant cells due to their ability to carry and transfer T-DNA from binary vectors. They are commonly used in the generation of transgenic plants, including model species like Arabidopsis thaliana and various crops. The presence of the pSoup plasmid provides essential replication functions for the helper plasmid, enabling stable maintenance of gene constructs. This strain is favored for its high transformation efficiency and compatibility with a broad range of plant expression vectors, making it a standard tool in plant genetic engineering and functional genomics studies.
