A study by Nagoya University reveals how Arabidopsis plants attract and repel pollen tubes using specific signals, aiding in precise fertilization and offering insights for agriculture.

One-to-one pollen tube guidance is a critical process in plant reproduction that involves precise navigation of pollen tubes to individual ovules. This mechanism ensures the successful fertilization of angiosperms by facilitating the specific coupling between ovules and individual pollen tubes. “I find the repulsion system fascinating,” Mizuta said. “The cells that generate the attraction system are mostly synergid cells, whereas the cells that generate the repulsion system include multiple types such as somatic and gametophytic cells at multistep levels. I find it very interesting that all couplings involve this mechanism of attracting and repelling.”
