Amylose in rice endosperm is mainly synthesized by waxy gene (Wx) encoding granule combined with starch synthase I (GBSSI), and Wx allelic diversity is one of the main reasons for changes in rice AC.
Recently, Shandong Normal University and Shunfeng Gene Editing Research Institute Zhang Jinshan's research group published online research papers in Acta Botany The study unearthed a rare Wx allele waxy abe2 .

The researchers used two base editing systems (ABE-NG and CBE-NG) to design 10 target sites (BE1-BE10) on the 7th and 10th exons in the central region of the Wx b allele To edit.

In addition, the study successfully separated the editing tool from the progeny of waxy abe2 , and its agronomic traits were not significantly different from the control.

It is reported that the research group is mainly engaged in the research work of gene editing in the improvement of rice traits.
