Simple Spectroscopic Determination of Nitrate, Nitrite, and Ammonium in Arabidopsis thaliana
[Abstract]  Plants use nitrate, nitrite, and ammonium as inorganic nitrogen (N) sources. These N compounds are included in plant tissues at various concentrations depending on the balance between their uptake and assimilation. Thus, the contents of nitrate, nitrite, and ammonium are physiological indicators of plant N economy. Here, we describe a protocol for measurement of these inorganic N species in A. thaliana shoots or roots.

Measurement of ATP Hydrolytic Activity of Plasma Membrane H+-ATPase from Arabidopsis thaliana Leaves
[Abstract]  Plant plasma membrane H+-ATPase, which is a P-type ATPase, couples ATP hydrolysis to H+ extrusion and thereby generates an electrochemical gradient across the plasma membrane. The proton gradient is necessary for secondary transport, cell elongation, and membrane potential maintenance. Here we describe a protocol for measurement of the ATP hydrolytic activity of the plasma membrane H+-ATPase from Arabidopsis thaliana leaves.

Preparation of Knockdown Transformants of Unicellular Charophycean Alga, Closterium peracerosum-strigosum-littorale Complex
[Abstract]  To prepare the knockdown transformants of the Closterium peracerosum-strigosum-littorale (C. psl.) complex, particle bombardment was applied with a newly constructed vector (pSA0104) with an endogenous constitutive promoter fused to a DNA fragment corresponding to an antisense strand of a target gene. Using a hygromycin resistance gene (aph7”), hygromycin-resistant colonies were selected. After the second screening, integration of the vector into the genome was ...
