Figure 1. Pollen Tube Growth and Guidance by the LURE Peptide in Arabidopsis (image) Institute of Transformative Bio-Molecules (ITbM), Nagoya University Share Print E-Mail Caption (A) Image showing the stamen and pistil in Arabidopsis. When pollen formed at the tip of the stamen (anther) reaches the pistil, the pollen tube starts to grow towards the inside of the pistil. The pollen tube grows until it eventually reaches the ovule, where it fertilizes an egg cell and develops a seed. (B) The synergid cell, located next to the egg cell, produces the pollen tube attractant, LURE. Once the pollen tube reaches the synergid cell, it releases its sperm cells, which is accepted by the egg cell, thus leading to fertilization. The LURE peptide of Arabidopsis thaliana consists of about 70 amino acids and is effective for specifically attracting the pollen tube of Arabidopsis thaliana.
