Berlin, September 24 : Molecular biologists at the Max Planck Institute for Developmental Biology in Tubingen, Germany, have discovered how the growth of leaves and the aging process of plants are coordinated, which can be referred to as the formula for longer plant life.
In their study, now published in PLoS Biology, scientists at the institute have shown that certain small sections of genes, so-called microRNAs, coordinate growth and aging processes in plants.
These microRNAs inhibit certain regulators, known as TCP transcription factors. These transcription factors in turn influence the production of jasmonic acid, a plant hormone.
