Key Findings
- The study by the Chinese Academy of Sciences explored how histone modification H3K4me3 affects gene expression during sperm cell development in tomatoes
- H3K4me3 was mainly found in promoter regions of genes and increased as sperm cells differentiated from somatic cells
- After microspore division, generative and sperm cells showed similar H3K4me3 patterns, distinct from vegetative cells
- There was a selective loss of H3K4me3 in hormone signaling genes, affecting brassinosteroid in generative cells and cytokinin in vegetative cells
