In plants, it has been clear for a while that maternal signals regulate embryo development. However, the signal itself was unknown -- until now. Plant scientists have now found that a plant hormone called auxin from the mother is one of the signals that pattern the plant embryo.

Bacteria engineered to create fertilizer out of thin air     2018/07/16 19:59

Researchers have created a bacteria that uses photosynthesis to create oxygen during the day, and at night, uses nitrogen to create chlorophyll for photosynthesis. This development could lead to plants that do the same, eliminating the use of some -- or possibly all -- human-made fertilizer, which has a high environmental cost.
