CIMBL55: a repository for maize drought resistance alleles

Droughts threaten crop yields worldwide. Compared to other major staple cereal crops, maize (Zea mays) is especially sensitive to drought, which can cause dramatic fluctuations in its yield potential.

description Droughts threaten crop yields worldwide. Compared to other major staple cereal crops, maize (Zea mays) is especially sensitive to drought, which can cause dramatic fluctuations in its yield potential. Natural maize populations contain many superior alleles that can enhance drought resistance through complex regulatory mechanisms. We recently de novo assembled the genome of a prominent drought-resistant maize germplasm, CIMBL55, and systematically dissected the genetic basis for its drought resistance on the genome, transcriptome, and epigenome levels. These analyses revealed 65 favorable drought resistance alleles in CIMBL55. Subsequently, we genetically verified the functions of the drought resistance genes ZmABF4, ZmNAC075, and ZmRtn16 and unraveled the function of ZmRtn16 on a molecular level.
