Targeting of pollen tubes to ovules is dependent on nitric oxide (NO) signaling.

Molecular plant - 1 Jul 2008

Prado Ana Margarida, Colaço Renato, Moreno Nuno, Silva Ana Catarina, Feijó José A

Abstract excerpt

The guidance signals that drive pollen tube navigation inside the pistil and micropyle targeting are still, to a great extent, unknown. Previous studies in vitro showed that nitric oxide (NO) works as a negative chemotropic cue for pollen tube growth in lily (Lilium longiflorum). Furthermore, Arabidopsis thaliana Atnos1 mutant plants, which show defective NO production, have reduced fertility. Here, we focus in...
