Figure 8From: Reduction of photosynthetic sensitivity in response to abiotic stress in tomato is mediated by a new generation plant activatorEffects of Alethea and salinity on proline and polyamine biosynthesis. Pathway diagram illustrating conversion of arginine and glutamate to ornithine and thence proline. Significant transcriptional effects of Alethea and salinity on genes encoding relevant enzymes (italics) are shown as red arrows for up-regulation and blue bars for down-regulation.Back to article page
