Protein Shield

Introduction

The protein that plays a key role in how plant roots use water and nutrients has been identified. Endodermis or the inner skin of the plant root cells helps control the movement of water and nutrients from roots to other parts of the plant. This is achieved through Casparian strip made of lignin. The strip helps plants tolerate salinity, drought and flood stress, too. How it forms has, however, been unknown. Now it has been found that ESB1 protein is responsible for lignin deposition on the Casparian strip, a process that helps the band grow and aid plant response to various stresses. Manipula - ting ESB1 gene can help devlop sturdy plants.
