Defensin-like polypeptide LUREs are pollen tube attractants secreted from synergid cells.
The team's previous research suggested synergid cells, which hug the embryo sac, direct the tubes once they approaches the ovary, a bit like an air traffic controller motioning a plane to the landing strip.
Networks of plunder: Archaeologists tracing the labyrinth of antiquities trafficking hope to shut it down, or at least slow it up Pollen tubes gravitate toward LURE1 protein (left, fluorescent green) expressed by synergid cells around Satohiro Okuda (left) and Tetsuya Higashiyama
In the new study, the researchers surveyed more than 2,000 proteins expressed on synergid cells to clinch the exact molecules luring pollen tubes to the embryo sac.
