Abstract excerpt
Maize breeding has greatly improved yield through single-cross hybrids, but the underlying gene regulatory changes remain unclear. This study analysed transcriptomes of landmark maize hybrids and their parents across developmental stages and planting densities. Compared with their parents, hybrids showed a trade-off in the expression of photosynthesis-related genes and stress-responsive genes. This expression...
