Transcriptome Analysis Reveals Complex Defensive Mechanisms in Salt-Tolerant and Salt-Sensitive Shrub Willow Genotypes under Salinity Stress

Figure 7

A schematic complex regulatory mechanism of salinity stress tolerance in shrub willow. Upon exposure to salinity stress, genes involved in cell wall integrity, antioxidant regulation, heat shock protein, hormone regulation, and transcription factor were upregulated in shrub willow. Red arrows represent upregulated genes. POD: peroxidase; GST: glutathione S-transferase; ABA: abscisic acid; HSP: heat shock protein.
