What is it about?
In plants under submergence, the translation for the majority of mRNAs is repressed, but a group of mRNAs are selected for translation. The mechanism of this selection remains largely unknown. We show here a kinase-translation initiation factor signaling relay regulates the translation of specific mRNAs in Arabidopsis under submergence.

Why is it important?
It was known for a long time that under hypoxia a group of mRNAs were selected for translation. Identification of the SnRK1-eIFiso4G1 signaling relay as the key regulator to achieve this selection opens a new route to dissect the regulatory networks controlling translational dynamics in plants under flooding stress.
Perspectives
Our findings contribute significant information toward our understanding of how plants respond to flooding stress and can be used toward crop improvement.
