With the increase in frequency and intensity of extreme rainfall events causing severe damage to crops worldwide, a new study has paved way to enhance flood tolerance of more crops species through genetic engineering.

In a new research published in peer-reviewed journal, Science, scientists studied how other crops behaved when submerged in water and found that the plants- a wild-growing tomato used for farming and a plant similar to alfalfa – all share at least 68 families of genes in common that are activated in response to flooding.

The rice variety chosen for research was one that is grown in tropical countries like India where it is well-adapted to endure monsoons and water-logging. Scientists found that some of the genes involved in that adaptation exist in few other plants but have not evolved to switch on when the roots are being flooded. Read more …
