Accidental Discovery: How a Whiff of an Unusual Chemical Transforms Seedlings Into Super Plants

Improving the ability of plants to endure stress often results in plants that produce less because they put more energy into defense than into growth. These plants continued growing at a faster rate throughout their whole lifetime.The plant on the left was not primed with ethylene, while the plant on the right was. Part of photosynthesis includes what is called carbon fixation, where plants take CO ₂ from the environment and utilize the CO ₂ particles as the structure blocks to make the sugars.During photosynthesis and carbon fixation, plants take in sunshine and transform it into the sugars that they use to grow.My laboratory group revealed that there is a large boost in carbon fixation– which means the plants are taking in much more CO ₂ from the atmosphere.Correlating with the increase in photosynthesis is a large increase in carb levels throughout the plant.

Enhancing the capability of plants to make it through stress frequently results in plants that produce less since they put more energy into protection than into development. As part of this policy, plants make various hormonal agents that are part of a regulatory network that enables them to adjust to ecological conditions.Ethylene was very first discovered as a gaseous plant hormonal agent over 100 years earlier. These plants continued growing at a much faster rate throughout their entire lifetime.The plant on the left was not primed with ethylene, while the plant on the right was. Part of photosynthesis includes what is called carbon fixation, where plants take CO ₂ from the environment and use the CO ₂ molecules as the building blocks to make the sugars.During photosynthesis and carbon fixation, plants take in sunshine and convert it into the sugars that they use to grow.My lab group showed that there is a big boost in carbon fixation– which implies the plants are taking in much more CO ₂ from the atmosphere.Correlating with the increase in photosynthesis is a large boost in carbohydrate levels throughout the plant. This consists of big increases in starch, which is the energy storage molecule in plants, and two sugars, sucrose and glucose, that provide fast energy for the plants.More of these particles in the plant has been connected to both increased growth and a better ability for plants to withstand stressful conditions.Our study shows that ecological conditions throughout germination can have profound and lasting effects on plants that might increase both their size and their tension tolerance at the exact same time.
