Discovery of a gene that helps plants control their response to disease could aid efforts to develop crops that are resistant to infection, research suggests.<\/p>\n

The findings could lead to ways to fine-tune the gene\u2019s activity to boost disease resistance, pointing towards more resilient crop breeds or new treatments for infections.<\/p>\n

It could help curb crop losses incurred by plant diseases. These are the leading cause of crop losses worldwide, accounting for 10 per cent of lost produce in key varieties.<\/p>\n

Fighting infection<\/strong><\/p>\n

Edinburgh scientists studied how, when plants are under attack from bacteria or viruses, they produce tiny amounts of a gas known as nitric oxide.<\/p>\n

This gas accumulates in plant cells and triggers a response from the plant\u2019s immune system.<\/p>\n

Researchers used a common cress plant, Arabidopsis thaliana, to study the genes that were triggered as nitric oxide levels rose.<\/p>\n

They found that a previously unknown gene \u2013 called SRG1 \u2013 is rapidly activated by nitric oxide and is also triggered during bacterial infection.<\/p>\n

Key regulator<\/strong><\/p>\n

Further analysis showed that SRG1 unleashes the plant\u2019s defence mechanism by limiting the activity of genes that suppress the immune response.<\/p>\n

By altering the activity of the SRG1 gene, the team was able to demonstrate that plants with higher levels of defence proteins produced by the gene were more resistant to infection.<\/p>\n

They also found that nitric oxide regulates the immune response, ensuring the plant\u2019s defence system does not over-react.<\/p>\n

An overactive immune system damages plants and stunts their growth, in the same way that auto-immune diseases in people cause the immune system to attack the body.<\/p>\n

Common mechanism<\/strong><\/p>\n

Researchers say that similar mechanisms, are likely to be found in many other species, and their findings could enable insights into fundamental processes that underlie immune regulation.<\/p>\n

The study, published in the journal Nature Communications, was funded by the BBSRC and the National Natural Science Foundation of China.<\/p>\n
