Activating Compound

Activating Compound Comment Organism Structure
2,4-dinitrophenol 2,4-dinitrophenol increases the expression of HVP1, treatment with abscisic acid and 2,4-dinitrophenol increases Na+/H+ antiport activity and proton translocating activities by H+-PPase and H+-ATPase in tonoplast vesicles, and treatment with abscisic acid also increases the amount of V-PPase protein of tonoplast vesicles, overview Hordeum vulgare
abscisic acid abscisic acid markedly induces the expression of HVP1 and slightly increased the expression of HVP10, treatment with abscisic acid and 2,4-dinitrophenol increases Na+/H+ antiport activity and proton translocating activities by H+-PPase and H+-ATPase in tonoplast vesicles, and treatment with abscisic acid also increases the amount of V-PPase protein of tonoplast vesicles, overview Hordeum vulgare
additional information HVP1 transcripts also increase 5 h after treatment with another synthetic auxin, 1-naphthaleneacetic acid, and native auxin, 3-indoleacetic acid, while the level of HVP10 transcript does not increase after treatment with the two auxins, no effect on gene expression by gibberellic acid, salt stress increases the levels of HVP and HVP10 transcripts in the roots of barley seedlings, osmotic stress also increases the levels of HVP1 transcripts in the roots Hordeum vulgare
