Several Bacteria (like Escherichia Coli) exhibit a form of sexual reproduction called Bacterial Conjugation. It is the transfer of genetic material between bacterial cells by direct cell-to-cell contact or by a bridge-like connection between two cells. It was discovered by Nobel Prize winners, Joshua Lederberg and Edward L. Tatum in 1946.

Explants are small pieces of plant parts or tissues that are aseptically cut and used to initiate a culture in a nutrient medium. Explants can be taken from different parts of a plant such as shoots, leaves, stems, flowers, roots, and from many types of mature cells provided they can de-differentiate into totipotent cells. Continue reading What are Explants?
Cellular Totipotency is the innate ability of a single cell to produce all cell types and to organize them into an entire organism when cultured in a suitable culture medium at an appropriate temperature and aeration conditions. Plant spores and Zygote are examples of single cells that show cellular totipotency. Continue reading What is meant by Cellular Totipotency?
