Today, global population has reached to 7.7 billion people, which is significantly higher than that few decades back. This rise in population has increased pressure on agriculture field at a massive rate. Feeding a huge population is challenging and scientists, researchers have been making persistent efforts to come up with solutions, and alternative that will reduce the pressure. Revolutionary steps taken in the past that included Green Revolution and now there is the need for next agriculture revolution.
In the Age of Fast and Accurate Gene Editing is Agriculture Revolution do not Dependent on Chance
Recently, Professor Zach Lippman form Cold Spring Harbor Laboratory (CSHL) collaborated with Yuval Eshed at the Weizmann Institute of Science in Israel to understand future state of agriculture. Their review showed examples form last 50 years biological research and focus on the major genetic modifications and mutation that triggered agriculture revolutions. It included, plant toleration of fertilizers and different climate, hybrid seeds that enhanced growth and resist diseases and few similar other results. These significant changes were a matter by chance, but modern genomics reveals that most of them are in-built in two core hormonal systems: Gibberrellin, which influences stem height; and Florigen, which controls flowering.
Following their review, Eshed and Lippman propose that now we need not have to wait for chance discoveries as we are in the age of fast and accurate gene editing. Instead, today a stage can be set up to overcome any modern-day challenge rather introducing a wide variety of crops to changes in these core systems.
Evidence reveals that in the past rare mutations of Gibberellin/DELLA and Florigen/Antiflorigen mutations spawned multiple revolutions. Now, creating novel diversity in these two hormone systems has higher chance and this will further unleash agriculture benefits.
