Figure 6From: A rice calcium-dependent protein kinase OsCPK9 positively regulates drought stress tolerance and spikelet fertilityExpression analysis of selected ABA- and stress-responsive genes in OsCPK9 -OX, OsCPK9- RNAi, and control lines under no stress, ABA, or PEG6000 treatments. Three-day-old rice seedlings were treated with 1 μM ABA for 14 days. Two-week-old rice seedlings were treated without (normal conditions) or with 20% PEG6000 for 8 h. Leaves were collected to detect transcript levels of those ABA- and stress-responsive genes. The mRNA fold difference is relative to that of WT samples under normal conditions. Data are means ± SE of three independent experiments.Back to article page
