Figure 3From: GmPRP2 promoter drives root-preferential expression in transgenic Arabidopsis and soybean hairy rootsGUS histochemical assays in T 3 transgenic Arabidopsis seedlings carrying GmPRP2p-1062, GmPRP2p-852, GmPRP2p-471 and GmPRP2p-369 constructs. Photographs were taken 1 d, 3 d, 5 d, 7 d, 10 d, and 20 d from seeds placed from 4°C to 22°C on 1/2 MS plates.Back to article page
