Scientists Discover Mechanism Controlling Plant Cell Growth, Potential Implications for Human Cells
Researchers have identified a mechanism that controls the growth of peroxisomes in plant cells, which could have implications for understanding similar processes in human cells. The study, conducted by a team led by Bonnie Bartel, focused on the protein PEX11 in Arabidopsis plants. This protein is known to assist in the division of peroxisomes, which are crucial for breaking down fatty acids during the early stages of plant growth. Using CRISPR technology, the researchers selectively disabled combinations of the five genes responsible for producing PEX11, revealing its role in controlling peroxisome size. The findings suggest that PEX11 helps manage the expansion and contraction of peroxisomes, a process that may be conserved across different species, including humans.
