Transforming Agriculture: Plants, Genetics, and Climate

The Role of Plants in Solving Climate Change: A Plant Geneticist’s Perspective

I recently had an epiphany. It dawned on me that I could actually play a role in solving one of the biggest problems facing mankind today – climate change. After dedicating over 30 years of my life to reach this point, I realized that every experiment I conducted and every person who worked with me in my lab was leading up to this one last big experiment.

As a plant geneticist, I live in a world where excessive CO2 levels in the atmosphere pose a significant threat due to human activity. However, I’ve come to appreciate plants as amazing machines whose job has been to absorb CO2. They have been doing this remarkably well for over 500 million years. They are truly skilled at it.

Having a sense of urgency as a mother, I want to leave my two children a better world than the one I inherited from my parents. It’s crucial to keep moving in the right direction and not the wrong one. Additionally, I’ve been dealing with Parkinson’s for the past 15 years, which has given me an even greater sense of urgency to make a difference while I still have the opportunity to be an active part of this endeavor.

Now, let’s shift our focus to CO2. Most people perceive it as a pollutant or even the villain in the story. However, as plant biologists, we see the other side of CO2. We remember something you may have forgotten – plants engage in photosynthesis. This vital process is responsible for all carbon-based life on Earth and is made possible by plants and photosynthetic microorganisms absorbing CO2 from the atmosphere.

Interestingly, plants and other photosynthetic organisms have a remarkable capacity to absorb CO2 – twentyfold or more than the amount released due to human activities. Even though we are struggling to reduce our emissions effectively, plants possess the potential, as photosynthetic organisms, to assist us in this challenge. Our hope is that they will play their part.

However, there’s a catch. We need to lend plants a helping hand because their natural inclination is to convert most of the absorbed CO2 into sugars. When the growing season ends, the plants decompose, and all the CO2 they worked so hard to remove from the atmosphere is released back into it. How can we encourage plants to distribute the absorbed CO2 into something more stable?

This is where a natural product called suberin comes into play. It is present in all plant roots and possesses remarkable carbon storage capabilities. Suberin breaks down into small particles that improve the soil with carbon, creating a new texture and enhancing its ability to retain water and essential minerals required for plant growth.

Now, you might wonder why this is the right time for a biological solution. Over the past 30 years, we have made significant progress in understanding the functions of genes in various organisms, including plants. Moreover, advancements in genomics have enabled us to expedite research at a faster and more affordable rate than ever before.

By transferring traits from one plant to another, we can make predictions about their behavior and potential impact. Additionally, breakthroughs like CRISPR have provided us with genetic editing tools to make targeted modifications in plants. All these factors align and make it possible to propose a solution to the climate change problem that involves leveraging the remarkable capabilities of plants.

So, how are we going to achieve this? Biology is coming to the rescue. We aim to enhance the production of suberin in plants, increase the number of roots, and promote deeper root growth. By combining these traits in a single plant, we can harness their collective power. We are already making progress in model plants like Arabidopsis, where we can conduct experiments more efficiently.

Once we identify plants with the desired traits and increased suberin production, we will transition our findings to crop plants. However, there are challenges ahead. We need farmers and seed companies to hug these innovations and make them accessible to all. We can’t afford to sacrifice yields or overlook the need to feed the growing population, which is projected to reach 11 billion by the end of the century.

Furthermore, the competition for land poses a significant obstacle. Conducting carbon sequestration experiments requires substantial land use, which cannot be at the expense of food production. The Earth’s ecosystems are already strained, and climate change is impacting agricultural yields worldwide. We must ensure that plants making more carbon and improving the soil do not deplete it of essential nutrients but instead enhance its fertility.

Despite these challenges, I remain optimistic. The urgency of the climate crisis is evident, and we cannot deny the need for action. With advancements in science and our understanding of plants, we have the tools and knowledge to make a difference. The science behind our approach is solid, and we have already discovered single genes that influence the desired traits. Moreover, we have multiple paths to achieve our goals, providing us with even more possibilities.

The vision of using plants as a solution to climate change is astonishing, but it’s not too good to be true. We have an audacious project to scale up our research, pave the way for pilots, and bring this incredible vision to life. I firmly believe that plants, with a little assistance from us, can achieve remarkable feats and secure a gold medal for humanity.

In conclusion, we have an exciting journey ahead of us. The role of plants in combating climate change is significant, and it’s time to give them the support they need.
