GENETIC ENHANCEMENT OF PLANTS

July 7, 2018

1. GENETIC ENHANCEMENT OF PLANTS. INTRODUCTION The genetic improvement of plants consists in creating new varieties from existing varieties (genetic diversity) . This gene transfer is done by directed crosses and selection of the best plants from these crosses (this requires knowledge of reproduction methods ). Other means of creating successful varieties exist including mutagenesis, protoplast fusion, transgenesis and somatic variations. Genetic improvement of plants is […]

Natural instability of the genome, basis of plant improvement

July 7, 2018

Plants like animals multiply their cells throughout their lives. The genetic material is copied, copied, generally identical. But sometimes a small change can induce interesting new features! This is Darwin’s theory on the evolution and adaptation of species. Today, with the explosion of knowledge in genetics, it becomes possible to improve grain more precisely, but also many fruits and […]

Spider silk: the secrets of its resistance finally revealed

July 1, 2018
