Appropriate leaf rolling enhances erect-leaf habits and photosynthetic efficiency, which consequently improves grain yield.Here, we reported the novel lateral organ boundaries domain (LBD) gene OsLBD3-7, which is involved in the regulation of leaf rolling.OsLBD3-7 works as a transcription activator and its protein is located on the plasma membrane and in the nucleus.Overexpression of OsLBD3-7 leads to narrow and adaxially rolled leaves.

Microscopy lock shock and barrel art of flag leaf cross-sections indicated that overexpression of OsLBD3-7 led ngetikin to a decrease in both bulliform cell size and number.Transcriptional analysis showed that key genes that had been reported to be negative regulators of bulliform cell development were up-regulated in transgenic plants.These results indicated that OsLBD3-7 might acts as an upstream regulatory gene of bulliform cell development to regulate leaf rolling, which will give more insights on the leaf rolling regulation mechanism.
