Ovule perforation technique and media components (plant growth regulators and L-glutamine) were tested on in vitro growth of immature (<3 mm) embryos of "Springerest" and "Earligrande" peaches. Ovule ...
Pollen tube guidance towards the ovule is an important step for fertilization in flowering plants. In order for this to happen, a pollen tube attractant peptide LURE guides the pollen tube precisely ...
A gradient (red) in the concentration of the plant hormone auxin determines that only one of the eight nuclei in a plant's embryo sac will become an egg. (The blue island in the image is a cell ...
Structure of a flower, consisting of a pistil (female part) in the center and stamen (male part) on each side. The pistil has ovules containing egg cells, and the stamen consists of pollen containing ...
A gradient (red) in the concentration of auxin, a plant hormone, determines that only one of the eight undifferentiated nuclei in a plant's embryo sac will become an egg. (In this image, a large ...
In the flowering plant world, reproduction means an intricate succession of events. It begins when a pollen grain that carries the sperm cells lands on the top of the pistil, the female reproductive ...
