Agrobacterium tumefaciens incites crown gall tumors when bacterial DNA integrates into plant nuclear DNA. Plant cells can express these integrated bacterial genes. Following insertion of desired genes into bacterial DNA using recombinant DNA techniques, this system permits introduction of these new genes into plant DNA. We discuss the potential for genetic manipulation of plants using Agrobacterium tumefaciens and the related organism Agrobacterium rhizogenes.

Introduction: Cisplatin is extensively employed in the treatment of multiple solid malignant tumors. Nevertheless, side effects such as cisplatin-induced ototoxicity (CIO) pose obstacles to tumor therapy.The important natural product chiisanoside from has abundant activity against CIO.

has been widely used in traditional Chinese medicine for several thousands of years. This plant is known for tonifying kidney Yang, strengthening muscles and bones, and dispelling wind and dampness. It is worth noting that icaritin, a prenylated flavonoid isolated from , has received increasing attention in recent years due to its wide range of pharmacological activities.

Background: To date, there is no effective cure for the highly malignant brain tumor glioblastoma (GBM). GBM is the most common, aggressive central nervous system tumor (CNS). It commonly originates in glial cells such as microglia, oligodendroglia, astrocytes, or subpopulations of cancer stem cells (CSCs).

To enhance the treatment of tumors that are resistant to radio- and chemotherapy while minimizing the side effects of radiochemotherapy, researchers are continuously seeking new active compounds for use in combination with radiotherapy. Therefore, the aim of our study was to examine the cytotoxic and radiosensitizing effects of an extract from St. John's Wort (, referred to as HP01, on human epithelial tumor cells in vitro.

Crown gall disease in plants is caused by "Agrobacteria", bacteria belonging to the family, which carry a tumor-inducing (Ti) plasmid. Unexpectedly, we found evidence that a natural isolate from a rose crown gall, called NBC51/LBA8980, was a bacterium that did not belong to the family. Whole-genome sequencing revealed that this bacterium contained three large DNA circles with rRNA and tRNA genes, representing one chromosome and two chromids, respectively, and two megaplasmids, including a Ti plasmid.
