Stomatal movement in Arabidopsis is driven by guard cell-localized and copper-insensitive CSD1 splice variant

Maryna Tsinyk, Kateřina Hlaváčková, Miroslav Ovečka…·Petr Dvořák

This study identifies a cell-type-specific CSD1 splice variant in Arabidopsis guard cells that promotes ABA-induced stomatal closure independently of Cu availability and miR398 regulation.

Protein and genetic interactions between RACK1A and FSD1 modulate plant development and stress granule-dependent response to salt in Arabidopsis.

Pavol Melicher, Petr Dvořák, Maryna Tsinyk…·Tomáš Takáč

This study identifies a protein and genetic interaction between RACK1A and FSD1 that modulates salt stress response and development in Arabidopsis by regulating ROS levels and stress granule formation.
