Spatial and single-nucleus transcriptomics reveal the complexity of genomic imprinting in maize

Genomic imprinting is a classic epigenetic phenomenon first discovered in maize, which occurs predominantly in the triploid endosperm and is thought to mediate parental influences on seed development. Previous studies based on bulk RNA sequencing of manually dissected endosperm h...

Polycomb protein ZmEMF1a restricts endosperm proliferation and directs differentiation via stage‐specific H2Aub1 and H3K27me3 landscapes in maize

Polycomb group (PcG) proteins serve as pivotal epigenetic repressors that govern the transcriptional programs underlying cell growth and differentiation. However, their functional roles in maize endosperm remain largely unexplored. Here, we characterize the recessive maize small-...
