Story summary

An international team of researchers has uncovered more than 200,000 regulatory DNA regions that shape key maize traits, including plant and ear height. With a remarkable heritability of 92-95%, these traits are strongly genetically controlled. Their studies identified 70 significant SNPs for plant height and 28 for ear height, highlighting stable SNPs that enhance drought resilience and adaptability.
