CC-4101 npq2 [Niyogi 145.2]
$30.00
From Krishna Niyogi, UC Berkeley, July 2006
Phenotype: carotenoid deficient
The npq2 mutant accumulates zeaxanthin and completely lacks antheraxanthin and violaxanthin under all light conditions. This is consistent with a defect in the enzyme zeaxanthin epoxidase.
