Increased Apigenin in DNA-Edited Hexaploid Wheat Promoted Soil Bacterial Nitrogen Fixation and Improved Grain Yield Under Limiting Nitrogen Fertiliser.

ABSTRACT: Nitrogen availability remains a principal constraint to crop productivity. Plants cannot directly assimilate the abundant nitrogen available in our atmosphere; instead, they rely on the uptake of inorganic forms of nitrogen, such as ammonium and nitrate from the soil. Nitrogen is a limiting nutrient in wheat production, and wheat yields are very responsive to nitrogen fertilisation. Only diazotrophic bacteria can convert atmospheric nitrogen to ammonia via biological nitrogen fixation (BNF), and although improving BNF in wheat has been a longstanding objective, there have been no descriptions of successful modification of wheat crops showing increased BNF in the literature. Here we describe the use of polycistronic multiplexed CRISPR to modify the flavone biosynthetic pathway of hexaploid
