CC-4105 npq1 lor1 arg7 mt+ [Niyogi 277-3D]
$30.00
From Krishna Niyogi, UC Berkeley, July 2006
Phenotype: carotenoid deficient; requires arginine
The npq1 mutant has normal levels of violaxanthin but cannot convert violaxanthin to antheraxanthin and zeaxanthin during exposure to excessive light, suggesting a defect in the enzyme violaxanthin de-epoxidase. For more on lor1, please see CC-2420.
