Overexpressing lncRNA LAIR increases grain yield and regulates neighbouring gene cluster expression in rice

The effect of long noncoding RNAs (lncRNAs) on crop yield is unknown. Here, the authors show overexpression of a lncRNA, transcribed from the antisense strand of the previously discovered gene cluster LRK, can upregulate LRK genes’ expression, change histone modification status of LRK1, and increase rice grain yield.
