New perspectives on botanic sciences

Plant biology has acquired a great interest in biotech company, because of the opportunity to modify plant genome and introduce genetic improvement. Of course, selecting the best types and matching them to obtain more productive species is a current practice since long time. We remember how Mendel performed his studies about genetics and hereditary law, matching different plants of pees in order to observe how phenotypical characteristics were transmitted to progeny.
So, how to match plants is an ancient knowledge for us. Now the diffusion of molecular biology techniques allows to fast the matching process and directly introduce genetic alterations in the exact point of genome. This new approach has the great advantage to be specific, fast and all the progeny has the new gene and the new quality. Modern botanic sciences can also use biochemical knowledge to activate or block signalling pathways and have new properties of plants in reversible manner. This could be useful to increase the productivity only in a limited period of the year, for instance when the environmental conditions are more favourable. In conclusion, molecular biology and biochemistry have a revolutionary impact also in ancient sciences, such as botanic, that have accompanied humans since the beginning.
