A Role for Inositol Pyrophosphates in Arabidopsis Defense Against Herbivorous Insects
Inositol pyrophosphates (PP-InsPs) are a family of molecules recently discovered to be implicated in a number of plant pathways such as auxin regulation, phosphate (Pi) sensing, and jasmonate-(JA)-regulated plant defense. Transgenic plants that overexpress inositol tetrakisphosphate 1-kinase …

Biochemical Characterization of Arabidopsis Enzymes Involved in Inositol Pyrophosphate Biosynthesis
… cues. One such signaling pathway is called inositol phosphate signaling. This research dissertation focuses on the inositol phosphate signaling pathway in plants, with emphasis on elucidating how a new class of signaling molecules collectively referred to inositol pyrophosphates are …

Inositol Pyrophosphate Phosphatases as Key Enzymes to Understand and Manipulate Phosphate Sensing in Plants
… group of secondary messenger molecules, inositol pyrophosphates (PP-InsP). PP-InsPs and their precursors, inositol phosphates (InsPs), are important for plant abiotic stress responses, hormone signaling, and other stress responses. While PP-InsPs are critical for plant survival, much …

Characterization And Identification Of Novel Regulators Of The Synthesis Of Phospholipids
… is coordinated with the synthesis of inositol, a precursor of inositol-containing lipids, by controlling expression of the genes encoding phospholipid biosynthetic enzymes. In addition to this well-characterized regulatory circuit controlled by the trans-acting factors Ino2, Ino4, and …

Connections Between Inositol Phosphate Signaling and Energy Responses in Plants
… for survival. One mechanism for this is the inositol phosphate (InsP) signaling pathway. This work focuses on the role of InsP signaling in maintaining energy homeostasis in the plant. InsP signaling is connected to energy sensing in plants via a protein complex containing both the inositol …

Polyphosphoinositide-derived signals in the regulation of vacuole membrane fusion and fission
… pathway that produces a series of water soluble inositol polyphosphate second messengers. I further found that deletion of any of the inositol polyphosphate kinases in the Plc1p pathway prevented Yck3p signalling, suggesting that the inositol pyrophosphates control Yck3p activity in some fashion. …

Elucidating the function of inositol pyrophosphate signaling pathways in Arabidopsis thaliana
… as the Phosphate Starvation Response (PSR). The inositol phosphate (InsP) signaling pathway is a crucial element of the plant's ability to regulate the PSR and respond to changing energy conditions. InsPs are synthesized from the cyclic 6-carbon polyol scaffold, myo-inositol. Inositol …

The Role of Arabidopsis thaliana P80 in Inositol Signaling
The myo-inositol signaling pathway in plants allows them to sense external environmental stimuli and respond to them. This signaling pathway depends on the dynamic levels of the second messenger, inositol(1,4,5)trisphosphate, which in turn is regulated by inositol polyphosphate 5-phosphatases …
