Genes, Genomes and Genetic Engineering in Citrus
Living organisms have many cells – each with genetic information to specify how plants look, taste and feel. This genetic information also determines whether plants can be infected by disease-causing organisms, like the bacterium causing HLB and the degree of damage caused by the disease. That genetic information, containing long strings of chemicals called DNA, is organized in individual units, called genes, that specify traits, like a lemon’s tartness or a tangerine’s color. This article explores classical breeding and genetic engineering techniques.
