The pectic polysaccharide rhamnogalacturonan II (RG-II), a highly conserved structural component in plant cell walls (Caffall and Mohnen, 2009), has been shown to crosslink via borate-diol ester bonds and to be necessary for plant growth (Kobayashi et al., 1996; O’Neill et al., ...

History of genetic engineering

Genetic modification caused by human activity has been occurring since around 12,000 BC, when humans first began to domesticate organisms. Genetic engineering as the direct transfer of DNA from one organism to another was first accomplished by Herbert Boyer and Stanley Cohen in 1973. Advances have allowed scientists to manipulate and add genes to a variety of different organism and induce a range of different effects. Since 1976 the technology has been commercialised, with companies producing and selling genetically modified food and medicine.
