It also is indicated that SPF (I) which mediates the auxin effect in low hormone concentration range (10 (-10)-10 (-7) M IAA) is the dominant isoform in roots, whereas SPF (II) which does in high hormone concentration range (10 (-7)-10 (-4) M IAA) is that in shoots.

Further, the vacuolar H (+)-ATPase had a peak of stimulation in a range from 10 (-8) to 10 (-10) M IAA, whereas the H (+)-pyrophosphatase was sensitive to a much broader range of IAA concentrations from 10 (-3) to 10 (-15) M.

Focal application of 2-DG resulted in local Ca (2+) alternans that was confined to the region of exposure. 2-DG and IAA slowed the decay kinetics of the [Ca (2+)](i) transient and delayed its recovery (positive staircase) after complete SR depletion, suggesting impaired activity of the SR Ca (2+)-ATPase (SERCA). 2-DG and IAA reduced the rate of reuptake of Ca (2+) into the SR which was accompanied by a 15-20% decrease of SR Ca (2+) load.

The results show that the humic fraction with low molecular size used in this study is endowed with the characteristic structural network described for most humic substances so far isolated and confirm the presence of IAA in this fraction.
Moreover, the analysis of the expression of genes encoding two putative maize nitrate transporters (ZmNrt2.1 and ZmNrt1.1) and of two maize H (+)-ATPase isoforms (Mha1 and Mha2) show that these substances may exert direct effects on gene transcription in roots, as shown for the Mha2 gene, and long-distance effects in shoots, as observed for the ZmNrt2.1 gene.
