Moreover, a particular focus is the exploration of the biological functions of Arabidopsis phosphatidylinositol monophosphate 5-kinase 2 (PIP5K2), which catalyzes the synthesis of phosphatidylinositol (4,5) bisphosphate, the precursor of two important second messengers (inositol 1,4,5-trisphosphate and diacylglycerol). Employing molecular and genetic approaches, the author isolates and characterizes the expression pattern, physiological functions and underlying mechanism of Arabidopsis PIP5K2. In doing so, he reveals that PIP5K2 is involved in regulating lateral root formation and root gravity response through modulating auxin accumulation and polar auxin transport, and also plays a critical part in salt tolerance. These findings shed new light on the crosstalk between PI signaling and auxin response, both of which fulfill crucial regulatory roles in plant development. 410 0$aSpringer Theses, Recognizing Outstanding Ph.D. Research,$x2190-5053 606 $aPlant enzymes 606 $aRoots (Botany)$xDevelopment 606 $aPlant cellular control mechanisms 606 $aPhosphoinositides 606 $aArabidopsis 606 $aProtein kinases 606 $aCellular signal transduction 606 $aBiological Science Disciplines$3(DNLM)D001690 606 $aPlant Physiological Phenomena$3(DNLM)D018521 606 $aPlant Biochemistry$3https://scigraph.springernature.com/ontologies/product-market-codes/L14021 606 $aPlant Physiology$3https://scigraph.springernature.com/ontologies/product-market-codes/L33020 606 $aPlant Anatomy/Development$3https://scigraph.springernature.com/ontologies/product-market-codes/L24019 615 0$aPlant enzymes. 615 0$aRoots (Botany)$xDevelopment. 615 0$aPlant cellular control mechanisms. 615 0$aPhosphoinositides. 615 0$aArabidopsis. 615 0$aProtein kinases. 615 0$aCellular signal transduction. 615 2$aBiological Science Disciplines. 615 2$aPlant Physiological Phenomena. 615 14$aPlant Biochemistry. 615 24$aPlant Physiology. 615 24$aPlant Anatomy/Development. 676 $a571.94 700 $aMei$b Yu$cDr.,$01852061 801 0$bMiAaPQ 801 1$bMiAaPQ 801 2$bMiAaPQ 801 2$bNZ-WeVUL 906 $aBOOK 912 $a9910298349803321 996 $aFunctional Characterization of Arabidopsis Phosphatidylinositol Monophosphate 5-kinase 2 in Lateral Root Development, Gravitropism and Salt Tolerance$94446671 997 $aUNINA
