REL2, A Gene Encoding An Unknown Function Protein which Contains DUF630 and DUF632 Domains Controls Leaf Rolling in Rice.

ABSTRACT:

Background

Rice leaves are important energy source for the whole plant. An optimal structure will be beneficial for rice leaves to capture light energy and exchange gas, thus increasing the yield of rice. Moderate leaf rolling and relatively erect plant architecture may contribute to high yield of rice, but the relevant molecular mechanism remains unclear.

Results

In this study, we identified and characterized a rolling and erect leaf mutant in rice and named it as rel2. Histological analysis showed that the rel2 mutant has increased number of bulliform cells and reduced size of middle bulliform cells. We firstly mapped REL2 to a 35-kb physical region of chromosome 10 by map-based cloning strategy. Further analysis revealed that REL2 encodes a protein containing DUF630 and D
