“…1a). Similar to these results, photosynthesis was decreased by copper in the sensitive Silene paradoxa L. populations, black mangle, and in red algae Antithamnion plumula (Gonzalez-Mendoza et al, 2013;Bazihizina et al, 2014;Zou et al, 2015). In addition, the excess copper decreased chloroplast pigment (including chlorophyll and carotenoids) concentration in the dinoflagellate Cochlodinium polykrikoides , as well as in the diatom Phaeodactylum tricornutum .…”

“…Photosynthesis in photosynthetic organisms is sensitive to environmental variation (Jamers et al, 2006;Gonzalez-Mendoza et al, 2013;Bazihizina et al, 2014;Zou et al, 2015). As expected, excess Cu 2+ caused a decrease in the photosynthetic efficiency of Prorocentrum minimum (Fig.…”

“…The effects of copper on S. alterniflora showed that the excess of Cu with ameliorate membrane permeability lead to the production of superoxide radicals and oxidative stress in plants, and then lead to the enhancement of lipid per oxidation in cell membrane [34]. This issue has been confirmed in several studies concerning the: 1) effect of lead and Cd in mung bean [35], 2) lead on sedum [36], 3) Cd on in Linum usitatissimum L [37], and 4) copper on duckweed, cucumber, and Silene paradoxa L [8,[38][39].…”

“…Generally, HMs lead to the inhibition of net photosynthetic rate (Pn) and intracellular CO 2 concentration [45]. Bazihizina et al (2015) [38] have shown that "stomatal closure attribution" is the most important reason for reducing photosynthesis in plants that are exposed to copper.…”

Nowadays, the contaminations generated by anthropogenic activities have had damaging effects on the life cycle of plants, particularly on the plants living in the vicinity of urban areas that are more associated with the life of people. Bamboo, as a local plant, is one of the most widely used plants in China. So, a pot experiment was conducted to investigate the effects of three HMs (Cu, Pb, and Zn) in four different concentrations (0 (for control), 500 mg/kg, 1000 mg/kg, and 200 mg/kg), with complete randomized design (CRD) by five replications for each treatment to measure the antioxidant enzymes, lipid per oxidation (LP), soluble protein (SP), gas exchange parameters, and morphological indexes in Sasa kongosanensis f. aureostriatus. The results indicated that the antioxidant responses had an arc-shaped trend with various alterations in which POD and CAT first increase with low concentration of HMs (500 mg/kg) and then decrease with the increase of heavy metal (1000 mg/kg and 2000 mg/kg). Additionally, measuring of MDA content and soluble protein illustrated that MDA content and soluble protein increase with excess of HMs in different levels, and also the excess of HMs significantly decreases the photosynthesis properties. Moreover, the results obtained by morphological indices showed that low concentration of HMs increases both percentage of shoot length and percentage of emerge plants at all three kinds of HMs, but observe a downward trend with excess of heavy metal in 1000 mg/kg and 2000 mg/kg. Overall, in "Sasa kongosanensis f. aureo -striatus, results indicated that low concentration of HMs (500 mg/kg) can help the plant growth, while excess of HMs (1000-2000 mg/kg) alleviates the plant growth. On the other hand, Pb revealed the lowest antioxidant

“…At different time points in both experiments, net photosynthetic rate and stomatal conductance were calculated on young fully expanded leaves in each treatment, using the open gas exchange system Li-6400 (LiCor Inc., Lincoln, NE, USA) as described in Bazihizina et al, 2015. Briefly leaf gas exchange measurements were taken on four plants from each treatment at ambient relative humidity (50-60%), ambient CO 2 , flow rate of 400 mmol s…”

A B S T R A C TPlants survive stressful conditions by employing three main strategies: escape, tolerance, and survival. Experiments were conducted to pinpoint the response strategy adopted by Tetradenia riparia to cadmium (Cd) stress by monitoring several physiological parameters and plants' ability to recover once the stress receded. Cadmium (30 and 150 mM) strongly affected shoot and root growth in a dose dependent manner, with almost complete inhibition of shoot growth, stomatal opening and CO 2 assimilation in plants exposed to 150 mM CdSO 4 . Independently of the CdSO 4 concentrations, plants excluded Cd from the aboveground tissues, with concentrations in shoots remaining around 0.1 mmol g À1 dry mass.Furthermore, Cd stress was associated with a decline in methylation of Lys4 of histone H3, likely associated with the transition from an active to a quiescent state. Surprisingly, Cd also induced the initiation of root primordia in T. riparia stems, which, once placed in a Cd-free media, quickly (24 h) developed into adventitious roots, which were likely the driving factor of the rapid resumption of leaf elongation and photosynthetic activity, which increased almost 20-fold over the 3 weeks of recovery. Therefore T. riparia ability to survive Cd stress was mediated by quiescence, which associated with an excluder strategy and stem root primordia formation, enabled rapid resumption of growth under Cd-free conditions.
