FIGURE 7

Proposed model showing the role of ABA, ethylene, and HSPs in seed germination. Red and blue dashed boxes indicate genes expected to positively and negatively regulate the seed germination, respectively. Arrows indicate positive regulation, and bars indicate negative regulation. Bold lines indicate gene functions supported by strong evidence, and dashed lines indicate gene function with limited evidence in seed germination, which requires further investigation.
