Plant scientists unravel a molecular switch to stimulate leaf growth
Date:1/24/2014

Ghent 22 January 2014. Mechanisms that determine the size of plants have fascinated plant scientists of all times, however they are far from understood. An international research team led by plant scientists from VIB and Ghent University report an important breakthrough in the scientific journal The Plant Cell. They identified a protein complex that controls the transition from cell division to cell specialization. By extending the activity of the complex during leaf growth, more cells divide, giving rise to larger leaves. These insights can now be used to guide plant breeding initiatives towards higher plant productivity.

More dividing cells, larger leaves

Cell division is essential for growth and development of all multicellular organisms. In plants, leaf growth consists of two different phases. A first phase is characterized by intense cell division, which leads to the formation of many new cells. During the second phase, cell division activity declines, the cells elongate and acquire a certain expertise. In a small leaf that just initiated from the stem, almost all cells are in the active division phase. Later on, when the leaf matures, cells at the top of the leaf switch to the specialization phase. The more time cells stay in the first phase, the more cells are being formed and the bigger the ultimate leaf size will be. It was already known that the protein ANGUSTIFOLIA3 (AN3) fulfils an important role in determining the timing and activity of cell division in the leaf. However, the precise mode of action of AN3 was not yet understood.

State-of-the-art techniques

To unravel a biological process on a molecular level, scientists typically develop plants in which genes are switched on or off. Studying the effect of these "aberrant" situations on plant growth can in some cases resolve the function of these genes. However, this approach often is like finding a needle in a haystack.
