"Unveiling the Genetic Inheritance Mechanism of Plants: Insights from a Groundbreaking Study"

Scientists have discovered how the protein DDM1 aids in the methylation process that silences "jumping genes" in plants, ensuring the preservation of epigenetic controls across generations. The study provides insights into how plants pass down genetic memories and could have implications for agriculture and human genetics. The research also sheds light on the role of DDM1-like proteins in maintaining DNA methylation in humans.

Cracking the Code: Unveiling How Plants Pass on Genetic Memories

Scientists at Cold Spring Harbor Laboratory have discovered how plants pass along chemical markers, known as epigenetic inheritance, that control the activation of transposons or "jumping genes." The researchers identified the protein DDM1, which helps place regulatory marks on DNA strands to keep transposons inactive. They found that DDM1 displaces specific histones, which are packing proteins that wrap around DNA, to expose sites needing methylation. The study also revealed that a histone found only in pollen acts as a placeholder during cell division, preserving epigenetic controls across generations. This research may have implications for agriculture, food supplies, and understanding how similar proteins maintain DNA methylation in humans.
