Scientists from the University of East Anglia found that certain soil bacteria can help plants grow better in salty conditions. These microbes were discovered to strengthen plant roots and increase crop yields. The team believes this discovery could lead to a new era in climate-resilient agriculture.

Soil salinity is becoming a major problem for farmers worldwide due to climate change, irrigation practices, and rising sea levels. Salt buildup in farmland can stunt plant growth, damage roots, and reduce crop yields.

A team of scientists from the University of East Anglia (UEA) led by Dr. Yanfen Zheng discovered that certain soil bacteria called pseudomonads can help plants grow better in salty conditions. These microbes were found to gather around plant roots exposed to salt stress and trigger internal changes that strengthen their physical structure and resilience.

The researchers examined root microbiomes from multiple crop species grown in different soil types and found that pseudomonads consistently gathered around plant roots exposed to salt stress. They also discovered that these bacteria carry specialized genes that help them tolerate high salt levels, including sodium transport systems and other stress-resistance mechanisms.

In a greenhouse study, the researchers introduced selected pseudomonad strains to soybean plants and found that they successfully colonized the roots and improved plant growth under salty conditions. The treated plants showed stronger root systems, better development, and higher yields compared to untreated plants grown in salty soils.

Why It Matters

This discovery could help farmers grow food on land that has become too salty for conventional agriculture, which is crucial for India's food security. Climate change is making soil salinity a major problem worldwide, so finding natural solutions like these microbes can be a game-changer for agriculture.
