Control of heat and oxidative stress adaptation by the DJ-1 paralogs in Arabidopsis thaliana

This study identifies AtDJ-1C and AtDJ-1E as critical antioxidants in Arabidopsis thaliana that enhance survival under heat and oxidative stress by regulating redox homeostasis and improving plant growth.

Conservation of heat stress acclimation by the inositol polyphosphate multikinase, IPMK responsible for 4/6-InsP7 production in land plants

This study identifies IPMK as the enzyme responsible for producing 4/6-InsP7 in land plants and shows its role in heat stress acclimation through regulation of HSF transcription activity.

ITPK1 regulates jasmonate-controlled root development in Arabidopsis thaliana

This study shows that ITPK1 regulates JA-dependent root development in Arabidopsis by controlling JAZ repressor protein expression, without affecting JA biosynthesis or protein levels.

Arabidopsis PFA-DSP-type phosphohydrolases target specific inositol pyrophosphate messengers

This study identifies Arabidopsis PFA-DSP proteins as specific inositol pyrophosphate phosphohydrolases, revealing their role in regulating these signaling molecules.

Arabidopsis inositol polyphosphate kinases IPK1 and ITPK1 modulate crosstalks between SA-dependent immunity and phosphate-starvation responses

This study shows that Arabidopsis IPK1 and ITPK1 modulate crosstalk between SA-dependent immunity and phosphate-starvation responses by affecting SA levels and PSI-gene expression.

Arabidopsis inositol polyphosphate kinases regulate COP9 signalosome deneddylase functions in phosphate-homeostasis

This study shows Arabidopsis InsP-kinases IPK1 and ITPK1 regulate CSN-CRL dynamics, affecting phosphate homeostasis and stress responses through deneddylation of cullins.

ITPK1 is an InsP6/ADP phosphotransferase that controls systemic phosphate homeostasis in Arabidopsis

This study shows ITPK1 generates PP-InsPs from InsP6 and regulates phosphate homeostasis in Arabidopsis by controlling InsP7 and InsP8 synthesis.

ITPK1-Dependent Inositol Polyphosphates Regulate Auxin Responses in Arabidopsis thaliana

This study shows that ITPK1 produces 5-InsP7, which binds to auxin receptors and influences plant growth responses.
