  "summary": "Histone deacetylation regulates plant development, yet its role in male gametophyte development and fertility remains unclear. Here, we show that histone deacetylase 6 (HDA6), an RPD3-like histone deacetylase, epigenetically regulates timely tapetal programmed cell death (PCD) and male fertility, predominantly during early flowering in Arabidopsis. Loss of HDA6 in axe1-4 causes early-stage male…",
