Acknowledgments

The authors are grateful to Mar González Ceballos for her excellent technical support. Moreover, we acknowledge the critical discussion of our work with experts in the field, including Ingo Dreyer (Universidad de Talca, Chile) and Begoña Benito (CBGP), who also kindly shared mutant seeds with us. In addition, the authors thank the NASC and ABRC for providing T-DNA insertion mutant seeds and plasmids for yeast two-hybrid studies.
