Fortalis, calcium mobility and plant stress signalling

The CaT technology in Fortalis® works by mobilizing calcium within the soybean plant as part of its natural stress signalling process. You may wonder, why does calcium mobility play such an important role in soybean yield?

Calcium typically has low mobility in the soybean plant. The distribution of calcium is poor in tissues of low transpiration and little apoplastic flow, such as in flowers and pods. This factor is even more problematic where flowers and pods are further away from the main stem. Poor mobility and distribution of calcium leads to flower and pod abortion.

  • Stress during flowering and pod formation results in abortion.
  • Abortion of flowers and pods reduces productivity.
  • Abortion rate may reach 84%, with the probability being highest for developing flowers and pods furthest from the main stem.

CaT technology stimulates selective ion transport channels in membranes, increasing the calcium concentration within the cytoplasm of cells as part of the stress signaling process. This improves localized calcium movement via the cytoplasm (symplastic pathway) rather than via the cell wall (apoplastic pathway) which is important in tissues with low transpiration, such as flowers and pods.

For numerous reasons, better distribution of calcium within the soybean plant leads to higher yield.

  • Strengthens the cell wall and plant membrane.
  • Enhances the formation of pollen tubes and germination of pollen.
  • Assists with the transport of nutrients.
  • Enables a healthier soybean plant to retain more flowers and pods.

By improving calcium mobility and causing better fixation of flowers and pods, Fortalis® increases the productive potential of soybean crops. The result is more soybean pods per plant and bigger seeds, and consistently higher overall yield.
