Fig. 4From: Adaptation mechanism and tolerance of Rhodopseudomonas palustris PSB-S under pyrazosulfuron-ethyl stressEffect of pyraxosulfuron-ethyl treatment on photo-pigments biosynthesis. Accumulation of carotenoid and bacteriochlorin in the pyraxosulfuron-ethyl treated (pyraxosulfuron-ethyl) or non-treated control (CK) PSB-S cells was measured using a modified methanol/acetone extraction method. Each treatment had three biological replicates. *, p < 0.05. Car, Carotenoid accumulation; Bchl, Bacteriochlorin accumulation; Total, total amount of Carotenoid and BacteriochlorinBack to article page
