Contribución al estudio del fósforo en suelos ácidos del noroeste de España. II. Relaciones entre valores representativos del P del suelo, obtenidos por incubación o agitación con solución 0.01 M de CaCl subíndice 2, y su absorción por trébol violeta por Arines, J, Alvarez, M.T.

“…P- adsorption uptake by red clover grown in an acid brown soil heavily fertilized 6 years before sampling, was correlated with soil P estimated after the procedure followed to obtain their adsorption isotherm, with the value X/logC proposed by Bache and Williams, and with the p extracted by shaking soil samples during 1 h with 0.01 M CaC12 solution. The high determination coefficient (R2 = 0.9847) between P uptake and P extracted with 0.01 M CaC12, suggest the possibility of using this extractant to test soil P status A diagram to estimate fertilizer needs is showed.…”

Mobilization of intrasporozoite Ca(2+) is essential for Theileria parva sporozoite invasion of bovine lymphocytes por Shaw, M.K.

“…First, reagents that produced an influx of Ca2+ into the parasite (A23187) blocked entry. Second, depletion of intrasporozoite Ca2+ levels (10 micro M A23187 + 1.0 mM EGTA) or an increase in the cytoplasmic buffering capacity of the sporozoite cytoplasm (by preloading sporozoites with MAPT/AM) inhibited invasion. …”

Down-regulation of catalase activity contributes to senescence induction in wheat leaves exposed to shading stress por Causin, Humberto Fabio, Marchetti, Cintia Florencia, Pena, Liliana Beatriz, Gallego, Susana Mabel, Barneix, Atilio Jose

“…Previous data suggest that the radiation signal transduction pathway may involve changes in Ca2+ and H2O2 homeostasis. For better a understanding of the interaction among the spectral composition of radiation, Ca2+ availability, and the antioxidant metabolism in the regulation of shade-induced senescence, detached wheat leaves were placed in a growth chamber and exposed to either blue (B, high BR transmittance) and/or green (G, very low BR transmittance) Lee® filters in the absence or presence of 0.8 mM verapamil (a Ca2+ channels blocker), 4.0 mM EGTA (a Ca2+chelator), or 8.0 mM 3-amino-1,2,4-triazole (a CAT inhibitor). …”
