Nitric oxide
- Peroxisomal plant metabolism – an update on nitric oxide, Ca2+ and the NADPH recycling network
Summary: Plant peroxisomes are nodes at the crossroads of different metabolic pathways (nitro-oxidative metabolism, lipid mobilization and photorespiration) which also house relevant molecules (H2O2, NO, NADPH, Ca2+ and lipid-derived signals).
- Calmodulin antagonist affects peroxisomal functionality by disrupting both peroxisomal Ca2+ and protein import
Editor's choice: Ca2+ is indispensable for the physiological functioning of peroxisomes in roots and leaves because its absence negatively affects the activity of key enzymes as well as the nitric oxide generation.
- Nitric oxide mediates stretch-induced Ca2+ oscillation in smooth muscle
Summary: Stretching of myocytes and maintenance at the stretched length results in a Ca2+ oscillation that is dependent on NO, but not on soluble guanylyl cyclase (sGC) or cGMP. This results from the activation of PI3K.
