Abstract
Provided are a gene KWE2 for regulating corn car grain weight and yield, a protein encoding same, and an expression vector thereof. Further provided are an InDel1 marker of the gene KWE2 for regulating corn car grain weight and yield, and the use thereof in plant trait improvement.
Claims10
A gene KWE2 for regulating ear grain weight and yield, comprising a nucleotide sequence selected from at least one of the following:
- a DNA molecule shown in SEQ ID NO.2;
- and
- a DNA molecule, wherein in the DNA molecule, based on sequence shown in SEQ ID NO.1 or SEQ ID NO.2, through insertion and/or deletion of one to several bases, the gene is down-regulated or silenced to positively regulate the ear grain weight and the yield.
An InDel1 marker of a gene KWE2 for regulating ear grain weight and yield, wherein a fragment at a chr2:
- 25587558-25585754 position is deleted/inserted in a promoter region of a Zm000010002882 gene based on a fourth edition of corn reference genome B73.
