Abstract:
Modern genetics and biochemistry have revolutionized our understanding of plant biology. However, biochemical genetics can be traced to the foundation of Mendelian genetics indeed one of the milestone discoveries of Mendels seven characteristics of pea plants could later be ascribed to be due to mutation in starch branching enzyme. Here we review both current and historical strategies for the elucidation of plant metabolic pathways and the genes which encode their component enzymes and regulators. We utilize this historical review to discuss a range of classical genetic phenomena including, epistasis, canalization and heterosis as viewed through the lens of contemporary high-throughput data obtained via the array of approaches currently adopted in multi-omics studies.
