The ability of a seed to germinate and establish a plant at the right time of year is of vital
importance from an ecological and economical point of view. Due to the fragility of these …

In angiosperms, double fertilization triggers the concomitant development of two closely
juxtaposed tissues, the embryo and the endosperm. Successful seed development and …

Programmed cell death (PCD) is a collective term for diverse processes causing an actively
induced, tightly controlled cellular suicide. PCD has a multitude of functions in the …

Epigenetic reprogramming consists of global changes in DNA methylation and histone
modifications. In mammals, epigenetic reprogramming is primarily associated with sexual …

The endodermis represents the main barrier to extracellular diffusion in plant roots, and it is
central to current models of plant nutrient uptake. Despite this, little is known about the …

The plant embryonic cuticle is a hydrophobic barrier deposited de novo by the embryo
during seed development. At germination, it protects the seedling from water loss and is …

The root cap surrounding the tip of plant roots is thought to protect the delicate stem cells in
the root meristem. We discovered that the first layer of root cap cells is covered by an …

The seed represents the unit of reproduction of flowering plants, capable of developing into
another plant, and to ensure the survival of the species under unfavorable environmental …
