A rare alle of TabZIP45-4B enhances wheat adaptation to low nitrogen growth conditions

Key Points

The aim was to investigate the effects of a rare allele of TabZIP45-4B on wheat's adaptation to low nitrogen conditions.
Isolated a rare allele of TabZIP45-4B through gene allele frequency quantification.
Knockout experiments performed to assess the role of TabZIP45-4B.
Introgressed the rare allele into modern wheat cultivars.
The knockout of TabZIP45-4B increased spike number and grain yield per plant under nitrogen deficiency.
The introgression improved multiple agronomic traits with reduced nitrogen input.
TabZIP45-4B downregulation led to enhanced tolerance to nitrogen starvation.

Abstract

We isolated a rare allele of TabZIP45-4B that tolerated nitrogen starvation by pooling gene allele frequency quantification. The knock out of TabZIP45-4B enhances spike number and grain yield per plant in wheat under nitrogen starvation conditions through downregulating the expression level of TaDWARF4. Introgression the rare allele into modern commercial cultivar improved multiple agronomic traits with little nitrogen input.
