Distinct short-range ovule signals attract or repel Arabidopsis thaliana pollen tubes in vitro
Abstract Background Pollen tubes deliver sperm after navigating through flower tissues in response to attractive and repulsive cues.Genetic analyses in maize and Arabidopsis thaliana and cell ablation studies in Torenia fournieri have shown that the female gametophyte (the 7-celled haploid embryo sac within an ovule) and surrounding diploid tissues
