Intracellular Localization of the Neurotoxin 2,4-Diaminobutyric Acid in Lathyrus sylvestris L. Leaf Tissue

Intracellular Localization of the Neurotoxin 2,4-Diaminobutyric Acid in Lathyrus sylvestris L. Leaf Tissue.

The intracellular distribution of the neurotoxin 2,4-diaminobutyric acid (DABA) in mature leaves of the perennial legume Lathyrus sylvestris L. var ;Lathco' (flatpea) was determined using subcellular fractions from mesophyll protoplasts. Chloroplasts contained about 15% of the cellular DABA. At least 75% of the DABA was vacuolar, based on the assumptions that each protoplast contained a single ...

Intracellular localization of nitrate reductase, nitrite reductase, and glutamic Acid dehydrogenase in green leaf tissue.

Greenhouse grown seedlings of corn (Zea mays L.) and foxtail (Setaria faberii Herrm.) were used as source material in determining the intracellular localization of nitrate reductase, nitrite reductase, and glutamic acid dehydrogenase, Nonaqueous and aqueous isolation techniques were used to establish that nitrite reductase is localized within the chloroplasts, but that nitrate reductase and glu...

Excitotoxicity of lathyrus sativus neurotoxin in leech retzius neurons.

The effects of Lathyrus sativus neurotoxin were studied on the cell membrane potential and cellular cation composition in Retzius nerve cells of the leech Haemopis sanguisuga, with ion-selective microelectrodes using liquid ion-exchangers. Bath application of 10(-4) mol/l Lathyrus sativus neurotoxin for 3 min depolarized the cell membrane potential and decreased the input resistance of directly...
