Timeline of Plant Tissue Culture and Selected Molecular Biology Events Tens of thousands of years ago. .. People wandered the earth, collecting and eating only what they found growing in nature. By about 8,000 BC, however, the first farmers decided to stay in one place and grow certain plants as crops — creating agriculture and civilization, in that order Thousands of years ago People first learn to use bacteria to make new and different foods, and to employ yeast and fermentation processes to make wine, beer and leavened bread Prior to 1750 Plants used for food; Plants domesticated, selectively bred for desired characteristics 1750-1850 Increased cultivation of leguminous crops and crop rotations to increase yield and land use 1838 Cell theory, suggesting totipotentiality of cells. Schleiden M. J., Arch. Anat., Physiol. U. wiss. Med. (J. Muller), 1838: 137-176; Schwann T., W. Engelman, No. 176 (1910). 1850's Horse drawn harrows, seed drills, corn planters, horse hoes, 2-row cultivators, hay mowers, and rakes Industrially processed animal feed and inorganic fertilizer 1859 Charles Darwin hypothesizes that animal and plant populations adapt over time to best fit the environment 1861 Louis Pasteur defines the role of micro-organisms and establishes the science of microbiology 1865 Gregor Mendel investigates how traits are passed from generation to generation - called them factors 1869 Johann Meischer isolates DNA from the nuclei of white blood cells 1882 Plants synthesize organ-forming substances that are polarly distributed. A 1900 European botanists use Mendel's Law to improve plant species. This is the beginning of classic selection. 1902 First but unsuccessful attempt of tissue culture using monocots. Haberlandt G., Sitzungsber Akad. Wiss. Wien, Math.-Naturwiss. Kl., 111: 69-92. Walter Suton coined the term "gene" and proposed that chromosomes carry genes (factors that Mendel said that could be passed from generation to generation) 1904 First attempt in embryo culture of selected Crucifers. Hannig B., Bot. Zeitung, 62: 45-80. 1909 Fusion of plant protoplasts though the products failed to survive. Kuster E., Ber. Dtsch. Bot. Ges., 27: 589-598.

1910 Thomas H. Morgan proved that genes are carried on chromosomes The term “biotechnology" coined 1921 Cultivation of fragments of plant embryos. Molliard M., C. R. Soc. Biol. (Paris), 84: 770-772 1922 Asymbiotic germination of orchid seeds. Knudson L., Bot. Gaz., 73: 1-25. In vitro culture of root tips. Robbins W. J., Bot.
