Pollination type recognition from a distance in the ovary is revealed by a global transcriptomic analysis.

ABSTRACT: Sexual reproduction in flowering plants involves intimate interactions between the growing pollen tube and the female reproductive structure. These interactions start immediately after pollen landing on the stigma and continue during the pollen tube journey through the style and the ovary. Thus, well before fertilization, genes in the gynoecium are affected by the growing pollen tubes. Genes activated at a distance in the ovary before pollen tubes arrival represent one class of such genes. Using a global transcriptomic approach, expression profiles obtained from compatible (SC), incompatible (SI), semi-compatible (SeC) and interspecific (IS) pollinations revealed that these pollinations are perceived differently from a distance in the ovary. As the pollen tubes grew along the style, more a
