Splicing regulation by RS2Z36 controls ovary patterning and fruit growth in tomato

Stavros Vraggalas, Remus R. E. Rosenkranz, Mario Keller, Yolanda Pérez‐Pérez, Samia Bachiri, Kerstin Zehl, Jessica Bold, Stefan Simm, Arindam Ghatak, Wolfram Weckwerth, Leila Afjehi‐Sadat, Palak Chaturvedi, Pilar S. Testillano, Michaela Müller-McNicoll, Kathi Zarnack, Sotirios Fragkostefanakis

This study identifies RS2Z36 as a splicing regulator that controls ovary patterning and fruit growth in tomato by affecting cell expansion and alternative splicing.

A plant-specific clade of serine/arginine-rich proteins regulates RNA splicing homeostasis and thermotolerance in tomato

Remus R. E. Rosenkranz, Stavros Vraggalas, Mario Keller, Srimeenakshi Sankaranarayanan, François McNicoll, Karin Löchli, Daniela Bublak, Moussa Benhamed, Martin D. Crespi, Thomas Berberich, Christos Bazakos, Michael Feldbrügge, Enrico Schleiff, Michaela Müller-McNicoll, Kathi Zarnack, Sotirios Fragkostefanakis

This study identifies RS2Z35 and RS2Z36 as plant-specific splicing factors that regulate HSFA2 intron splicing and thermotolerance in tomato under heat stress.

Phenotypic analysis of Arabidopsis transgenic plants constitutively expressing the P6 protein from Cauliflower mosaic virus or mutant alleles thereof

Angèle Geldreich, Christophe Himber, Gabrielle Haas, Mario Keller, Olivier Voinnet

The paper confirms that constitutive expression of CaMV P6 in Arabidopsis causes stunted growth and chlorotic leaves, while mutant alleles do not.
