Combining two main <i>NAL1</i> functional alleles can increase rice yield.

ABSTRACT: NARROW LEAF1 (NAL1) is one of the key genes in regulating photosynthesis and plant architecture. As the antagonistic effects of NAL1 have concurrent impacts on photosynthesis and yield component traits, how we can effectively utilize the NAL1 gene to further increase rice yield is not clear. In this study, we used two different main functional NAL1 alleles, each of which has previously been proven to have specifically advantageous traits, and tested whether the combined NAL1 alleles have a higher yield than the homozygous alleles. Our results exhibited that the combined NAL1 alleles had better parent heterosis (BPH) for panicle number and the total filled grain number per plant, and had middle parent heterosis (MPH) for spikelet number per p
