Description
Bo Zhu leads a team mapping gene control in rice pollen formation in a 2026 journal article. Making male reproductive cells, the cells that form sperm, requires deep resetting of chemical marks on DNA and its packing proteins. The team profiled these marks and gene activity cell by cell, from early dividing cells through to sperm cells.
Gene programs in later cells were largely set up by packing states laid down earlier, they found. One activating mark placed during the key division stayed in place, while a repressive mark faded over time. DNA methylation, a silencing chemical tag, stayed mostly stable, with one brief dip. Blocking the enzyme that places the activating mark disrupted later gene activity and pollen growth.
