Figure 7From: Humic matter elicits proton and calcium fluxes and signaling dependent on Ca2+-dependent protein kinase (CDPK) at early stages of lateral plant root development Relative expression of OsCPK17 , OsCPK7 , OsA7 , and OsTPC1. Relative expression of (A) OsCPK17, (B) OsCPK7, (C) OsA7, and (D) OsTPC1 in rice root tissues treated with humic acids (HA) at 2.7 mM C L−1. Actin cDNA (AK100267) was used as endogenous control. Bars represent average ± SE (standard error) from three replicates.Back to article page
