Scientists discovered a surprising way plants grow. They found that some tiny land plants have a special trick to help them make food from sunlight more efficiently. This could one day help crops like wheat and rice grow better.

Photosynthesis is the process by which plants make their own food using sunlight, water, and air. It's essential for life on Earth. However, there's a major limitation in agriculture involving an enzyme called Rubisco. Rubisco plays a crucial role in photosynthesis but works slowly and can easily interact with oxygen instead of carbon dioxide, wasting energy and reducing plant growth.

A team of international scientists led by researchers at the Boyce Thompson Institute, Cornell University, and the University of Edinburgh discovered that some land plants have evolved ways to overcome this inefficiency. They found a rare group of land plants called hornworts that contain carbon concentrating compartments similar to those found in algae.

The key element is an unusual protein component named RbcS-STAR. This additional tail behaves like molecular velcro, causing Rubisco proteins to stick together and form clustered structures inside the cell. The researchers tested this mechanism in other plants and found it works across different plant species.

This discovery could one day help scientists redesign important crops like wheat and rice so they convert sunlight into food more efficiently.

Why It Matters

Understanding how plants grow could lead to better crop yields, helping India feed its growing population. This research also highlights the importance of basic scientific discoveries in improving our daily lives.
