摘要: Abstract The aquatic plant Trapa natans L. is highly resistant to Mn and moderately Mo, mainly thanks its ability sequestrate the metals by chelation in vacuole. Excess of Mo causes somewhat aspecific toxicity symptoms plants, but main target their seems be photosynthetic process. In this work, we aimed at understanding how effect on photosynthesis caused (130 μM, full recovery) or (50 μM, partial T. natans linked changes occurring apparatus, with emphasis Photosystem II (PSII), during a 10 day treatment these metals. time-course net photosynthesis, pigment content, amount PSII peripheral antenna LHCII, room-temperature fluorescence emission ratios F694/F680 F700/(F685 + F695) showed that early inhibiting (one exposure) was essentially non-specific respect metal, though more marked Mo- than Mn-treated plants. During subsequent recovery phase, still impaired assembly and, consequently, could not reach control values. Conversely, plants fully re-established, as metal induced accumulation LHCII. extent inhibition effectiveness are proposed reflect different safely excess vacuoles.
