1.3.1.81	malfunction	Keyuan-1 remains a higher pulegone reductase activity, while that of wild-type seedlings is severely decreased, which declined to the 17.71% of the control	746411	
1.3.1.81	metabolism	p-menthane monoterpene biosynthesis in peppermint glandular trichomes, generation of a mathematical model of peppermint essential oil biosynthesis, monoterpene contents in the essential oil, overview	713312	
1.3.1.81	additional information	simulation of the effects of environmental stress conditions on essential oil profiles, glandular trichome dynamics, overview. Substantially higher proportion of large-sized glandular trichomes, fewer medium-sized trichomes, and no small trichomes on plants lead to decreased (+)-pulegone and increased (-)-menthone contents	713312	
1.3.1.81	additional information	UV-B irradiation does not affect the enzyme expression neither in field plants not in growth chamber plants, overview	712853	
1.3.1.81	physiological function	the Pr activity determines the critical intermediate step to process pulegone and increase essential oil content of the derived products menthone and menthol. Salt-tolerant peppermint Keyuan-1 cultivar maintains normal growth and keeps higher yield and content of essential oils under NaCl stress than wild-type peppermint, but shows no obvious changes in essential oil composition and transcriptional level of enzymes related to essential oil metabolism. The activity of pulegone reductase in salt-tolerant peppermint Keyuan-1 peppermint cultivar preserves the higher amount of menthol and menthone as well as the lower content of menthofuran upon the 150-mM NaCl stress.
