Bicoid is one of the important Drosophila maternal genes involved in the control of embryo polarity and larvae segmentation. To clone and characterize the rice bicoid-related genes, one cDNA clone, ...

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 ...

A new generation of high yield plants could be created following a fundamental change in our understanding of how plants develop, experts say. The research provides the first evidence that plants have ...

This release is available in German. In flowering plants, the beginning of embryogenesis is almost exclusively governed by maternal gene activity. Maternal factors regulate the development of the ...

In the seed of the thale cress, the embryo forms from the fertilised egg cell that initially divides into two daughter cells. One of these two cells later goes on to form almost the entire embryo, ...

Plant embryogenesis is intimately associated with programmed cell death. The mechanisms of initiation and control of programmed cell death during plant embryo development are not known. Proteolytic ...

While pregnancy in humans and seed development in plants look very different, parallels exist - not least that the embryo develops in close connection with the mother. In animals, a whole network of ...

Via ScienceDaily (May 30, 2011) — In flowering plants, the beginning of embryogenesis is almost exclusively governed by maternal gene activity. Maternal factors regulate the development of the embryo ...
