Summary Introduction

To discuss: How the TAL protein’s structure suggests its functions on the basis of its interaction with DNA.

Concept introduction:

TAL proteins are found in Xanthomonas bacterium. It stands for transcription activator–like (TAL) effector proteins. These are secreted when the bacteria infect certain plant species such as rice, citrus fruits, cotton, and tomatoes. TAL effector proteins contain DNA-binding region through which they enter the plant nucleus and activate transcription leading to infection in the plant.
