additional information | DXR gene silencing by RNAi using Agrobacterium tumefaciens strain LBA4404, mutants phenotype, detailed analysis, overview. AaDXR-RNAi plants show no significant variation of stomatal length and density at the abaxial side of leaves. No significant alteration of floral initiation and flower opening is observed in the transgenic plants. The trichome density and area in leaves and flower buds are analyzed by fluorescence microscopy. It is evident that leaves of transgenic Artemisia annua in vegetative stage carry considerably lower density of trichomes than that of control. The trichome area of transgenic Artemisia annua is larger than that of control. During the flower formation, there is no difference of trichome density and area on flower bud surface between transgenic plants and control. Significant decline in chlorphylls Chla and Chlb is found in various growth stages of transgenic plants. Net photosynthesis rate of in DXRRNAi plants is decreased by 20.0-31.4% compared with that of the controls | Artemisia annua |
