Cytoplasmic free Ca2+ in Arabidopsis roots changes in response to touch but not gravity.

abstract：:Pyridine nucleotide pools were measured in intact plastids from roots of barley (Hordeum vulgare L.) during the onset of NO2- assimilation and compared with the in vitro effect of the NADPH/NADP ratio on the activity of plastidic glucose-6-phosphate dehydrogenase (G6PDH, EC 1.1.1.49) from N-sufficient or N-starved roo...

abstract：:Pulvinar motor tissues of Samanea saman are often excised for in vitro studies of ion transport. Because ion transport may be regulated in part by hydrostatic pressure (P), this study explores how P and water potential (Psi) change when motor tissues are excised. Water potential (Psi) of excised extensor and flexor ti...
