In a groundbreaking advancement for agriculture and biotechnology, researchers at the Institute of Agricultural Biotechnology, Jilin Academy of Agricultural Sciences, have successfully enhanced maize resilience to nitrogen stress using third-generation nanopore sequencing technology.
Led by Qing Liu, the study, published in the journal Scientific Reports, focuses on introducing the ZmNRT1.1A gene into the maize variety y822, resulting in two transgenic maize events: ND4401 and ND4403. These maize varieties demonstrated improved nitrogen efficiency, a critical trait for modern agriculture grappling with soil nutrient depletion and sustainable farming challenges.
Using nanopore single-molecule sequencing, the team accurately identified the precise locations of the gene insertions and their surrounding genomic regions. This precision is a game-changer for evaluating the safety and effectiveness of transgenic crops, paving the way for clearer assessments of potential risks and benefits.
