Expression of Clementine Asp-Rich Proteins (CcASP-RICH) in Tobacco Plants Interferes with the Mechanism of Pollen Tube Growth by Luigi Parrotta, Lavinia Mareri, Iris Aloisi, Claudia Faleri, Gaetano Distefano, Alessandra Gentile, Angela Roberta Lo Piero, Verena Kriechbaumer, Marco Caruso, Giampiero Cai, Stefano Del Duca

“…In this article, we analyzed the effects induced by clementine ASP-RICH proteins (CcASP-RICH) when expressed in the tobacco heterologous system, focusing on the male gametophyte. The aim was to gain insight into the mechanism of action of ASP-RICH in a well-known cellular system, i.e., the pollen tube. …”

Deciphering <i>S</i>-RNase Allele Patterns in Cultivated and Wild Accessions of Italian Pear Germplasm by Stefania Bennici, Mario Di Guardo, Gaetano Distefano, Giuseppina Las Casas, Filippo Ferlito, Paolo De Franceschi, Luca Dondini, Alessandra Gentile, Stefano La Malfa

“…The genus <i>Pyrus</i> is characterized by an <i>S</i>-RNase-based gametophytic self-incompatibility (GSI) system, a mechanism that promotes outbreeding and prevents self-fertilization. …”

The origin and the genetic regulation of the self-compatibility mechanism in clementine (Citrus clementina Hort. ex Tan.) by Stefania Bennici, Lara Poles, Mario Di Guardo, Lawrence Percival-Alwyn, Mario Caccamo, Concetta Licciardello, Alessandra Gentile, Gaetano Distefano, Stefano La Malfa

“…In Citrus, recent evidences have shown the presence of a gametophytic SI system based on S-ribonucleases (S-RNases) ability to impair self-pollen tube growth in the upper/middle part of the style. …”
