NPR1 as a transgenic crop protection strategy in horticultural species

Abstract

Plant immunity: Engineering for enhanced resistance Introducing the plant immunity gene NPR1 into fruits and vegetables may help to protect them against diseases and pests, which are emerging and migrating faster than resistance can be developed using traditional breeding methods. Pandemics currently threaten crops such as banana, cacao, citrus, and avocado, and genetic engineering may offer a rapid, low-input alternative for crop protection. Kevin Folta at the University of Florida and co-workers reviewed the use of NPR1 to boost immunity in horticultural plants. NPR1 was first tested in high-acreage crops such as rice, and it is now being tested in strawberry, grapevine, tomato, carrot, cotton, citrus, tobacco, and many others. Introducing NPR1 usually improves resistance, and researchers are testing ways to minimize undesirable side effects, such as reduced yield. Transgenic approaches show promise for helping plants adapt to modern stresses.
