Allium cepa | a significant increase in activity is observed in the leaves of the pungent cultivar Kojak in response to added sulfur but not in the less pungent cultivar Encore. In hydroponically-grown plants, levels of enzyme transcripts are significantly higher in the roots of sulfur-sufficient when compared with sulfur-deficient plants of the pungent cultivar W202A but not the less pungent cultivar Texas Grano 438. A higher level of enzyme activity is also observed in the sulfur-sufficient treatment in leaves of both cultivars before and after bulbing | up |
