Chinese scientists have highlighted two major genes responsible for Soragham’s double-anaz spikelets that dramatically increase grain number and crop yield. The DG1 (Double-Grain 1) promoters a sufficient 35.7-cilobes intracromosomal inverted DG1 to operate the expression of expression, leading to the development of double-anaz spikelets, which increases the number of daints showing the important role of genomic structural variation in the plant evolution.
