Title:
METHOD FOR CULTIVATING AND SCREENING RICE ON BASIS OF AMYLOSE CONTENT AND USE OF NOVEL WX PROMOTERS CREATED THEREBY
Document Type and Number:
WIPO Patent Application WO/2021/147134
Kind Code:
A1
Abstract:
Provided are a method for cultivating and screening rice on the basis of an amylose content and promoters, i.e. Wx b1, Wx b2, Wx b3, Wx b4, Wx b5, Wx b6 and Wx b7, suitable for rice Wx gene expression and created on the basis of the method, the nucleotide sequences of the promoters being as shown in SEQ ID NOs: 8-14, respectively. The method comprises modifying the promoters of the rice Wx gene. The method and the promoters are used for the improved breeding of rice varieties and the regulation of the rice Wx gene expression, thereby regulating the amylose content of rice and improving the eating and cooking quality of rice.
