Fields like Computer Science, Physics/Astronomy, and Chemistry saw the largest increases in NSF GRFP awards in 2025.

Meanwhile, Life Sciences, Social Sciences, Psychology, and Mathematical Sciences experienced the steepest declines—marking a major departure from historical funding patterns.

Congrats!!

Thanks! It certainly seems that a common theme is structural DNA variation affecting allele-specific regulation of flowering genes to regulate timing. In this case, we don't find evidence that the mechanism directly involves the 3' UTR

We discuss the implications of our findings for evolution of heterodichogamy, and turnover vs stability of the genetic systems that control it.

Heterodichogamy in Cyclocarya involves a distinct pair of alleles at GFAFL with a reversed direction of dominance. The alleles are specialized in unisexual flowers and expr again implies a trans interaction. Parallel genomic structure to the Pterocarya locus suggests a similar mechanism in both
