Maize Plant Genetics Shape Root Health and Growth

Rodielon Putol, an Earth.com staff writer, writes that maize genetics plays an important role in determining the health and efficiency of plant roots. There is a connection between the genetic makeup of maize plants and the composition of microorganisms surrounding their roots. The roots are an important for of plants because they are their lifelines. Roots anchor an enable nutrient & water absorption. They also have a tiny microbial layer that is vital for plant health. The microorganisms are crucial for the health and fitness of plants. This research takes a Segway from the original belief that only soil influences the root microbiome. It shoes that maize genetics are equally important in determining which microorganisms surround the roots. 

Since maize has been cultivated through selective breeding in diverse climates over centuries, researchers decided they would harness its genetic diversity. Specific genes were studied to see how the plant interacts with bacteria which could enhance the plant’s resilience to environmental challenges. Massilia bacteria was found around maize roots that helped improve nutrient and water absorption. We can use the findings in this study to breed maize to be more resilient when it comes to droughts and food shortages. This plant is known to be a big food sources for the locals and it would be greatly beneficial to genetically modify them be resilient to certain bacteria. We can develop tougher maize varieties which can also lead to significant advancements towards sustainable agriculture. I’m glad that we are finding ways of making maize plants last longer in their life spans as it will help feed a lot of people who depend on it as their food source.
