GhMPK17, a Cotton Mitogen-Activated Protein Kinase, Is Involved in Plant Response to High Salinity and Osmotic Stresses and ABA Signaling
Figure 3
Quantitative RT-PCR analysis of GhMPK17 expression in cotton under normal conditions and different stresses.
(A) Quantitative RT-PCR analysis of GhMPK17 expression in cotton tissues. Total RNA was isolated from roots (R), hypocotyls (H), cotyledons (C), leaf (L), anthers (A), petals (P), ovules (O), and fibers (F). (B) Quantitative RT-PCR analysis of GhMPK17 expression in cotton under different stresses. Total RNA was isolated from 6-day-old cotyledons treated with 100 µM abscisic acid (ABA), 200 mM NaCl and 200 mM manntiol (Man), respectively, using the untreated 6-day-old cotyledons as control (MS). Relative value of the expression of GhMPK17 in cotton was shown as percentage of GhUBI1 expression activity. Mean values and standard errors (bar) were shown from three independent experiments. *, P<0.05.
