**About the Editors**

**V´ıctor Quesada** is an Associate Professor at the Universidad Miguel Hernandez de Elche ´ (UMH), Spain. He completed his undergraduate studies in Biology at the Universidad de Alicante, Spain, in 1993, and received his Ph.D. at the UMH, working on the isolation and characterization of salt tolerant mutants in the plant model system, *Arabidopsis thaliana* (1999). He moved then to the John Innes Centre (JIC) in Norwich, UK, with a post-doctoral fellowship from 2000 to 2003, to study the regulation of the *FCA* gene and its function in the promotion of flowering in Arabidopsis, at the laboratory of Dr. Caroline Dean. After finishing his post-doc at the JIC, he moved to the Bioengineering Institute of the UMH to research leaf morphogenesis at the laboratory of Dr. Jose´ Luis Micol, until December 2008. He became an Assistant Professor (December 2003) and an Associate Professor in 2009 at the UMH. Since 2009, his research activity has been focused on the functional characterization of Arabidopsis nuclear genes involved in organellar gene expression, principally those encoding mitochondrial transcription termination factors (mTERFs) and organellar ribosomal proteins, to shed light on the understanding of their roles in plant growth, development and adaptation to abiotic stress. He is currently Guest Editor and Topic Editor of the *International Journal of Molecular Sciences*, and member of the Editorial Board of the journal *Plants*.

**Pedro Robles** is currently an Associate Professor in Genetics at the Universidad Miguel Hernandez de Elche (UMH), Spain. He obtained, in 1993, a bachelor's degree in Biology at the ´ Universidad de Alicante, Spain, and received his Ph.D., in 2000, at the UMH, working on the isolation, characterization and mapping of leaf developmental mutants in *Arabidopsis thaliana* (2000) at the laboratory of Dr. Jose Luis Micol. After finishing his Ph.D., he joined the laboratory of Dr. Martin ´ Yanofsky at the University of California San Diego, UCSD, USA, with a post-doctoral fellowship, contributing to ascertaining the role of several *MADS-Box* genes in *Arabidopsis* flower and fruit development. After this post-doctoral period, he moved in 2003 to the Bioengineering Institute of the UMH, as an Assistant Professor, to resume his research on leaf morphogenesis until 2008. He became an Associate Professor in 2009 and, together with Dr. V´ıctor Quesada, found a new research group interested in the control of the flux of genetic information inside chloroplasts and plant mitochondria, and how this regulates plant development and stress responses.
