Glutamate receptor-like channels are essential for chemotaxis and reproduction ...
Ortiz-Ramírez, Carlos; Michard, Erwan; Simon, Alexander A.; Damineli, Daniel S. C.; Hernández-Coronado, Marcela; Becker, Jörg D.; Feijó, José A.Glutamate receptors are well characterized channels that mediate cell-to-cell communication during neurotransmission in animals. Nevertheless, information regarding their functional role in organisms without nervous systems is still limited. In plants, Glutamate Receptor-like (GLR) genes have been implicated in defence against pathogens, reproduction, control of stomata aperture and light signal transduction(1-...
A Transcriptome Atlas of Physcomitrella patens Provides Insights into the Evolu...
Ortiz-Ramírez, Carlos; Hernandez-Coronado, Marcela; Thamm, Anna; Catarino, Bruno; Wang, Mingyi; Dolan, Liam; Feijó, José A.; Becker, Jörg D.Identifying the genetic mechanisms that underpin the evolution of new organ and tissue systems is an aim of evolutionary developmental biology. Comparative functional genetic studies between angiosperms and bryophytes can define those genetic changes that were responsible for developmental innovations. Here, we report the generation of a transcriptome atlas covering most phases in the life cycle of the model br...
HydroxyprolineO-arabinosyltransferase mutants oppositely alter tip growth inAra...
MacAlister, Cora A.; Ortiz-Ramírez, Carlos; Becker, Jörg D.; Feijó, José A.; Lippman, Zachary B.Hydroxyproline O-arabinosyltransferases (HPATs) are members of a small, deeply conserved family of plant-specific glycosyltransferases that add arabinose sugars to diverse proteins including cell wall-associated extensins and small signaling peptides. Recent genetic studies in flowering plants suggest that different HPAT homologs have been co-opted to function in diverse species-specific developmental contexts....
