“…However, the accumulation of Zn was much greater in cucumber, up to twice the amount, than in tomato with ZnSO 4 alone (Table 2). This is not surprising since Cucurbits have been described as Zn bio-accumulators (Gyulai et al, 2012), and, therefore, the plants should be more resistant to Zn levels. In agreement, the levels of Ca, Mg and Fe in cucumber were not affected under such conditions, while the concentration of all the nutrients strongly decreased in tomato plants, pointing to a higher sensitivity to Zn.…”

Salinity and excess zinc are two main problems that have limited agriculture in recent years. Aquaporins are crucial in regulating the passage of water and solutes through cells and may be essential for mitigating abiotic stresses. In the present study, the adaptive response to moderate salinity (60 mM NaCl) and excess Zn (1 mM ZnSO4) were compared alone and in combination in Cucumis sativus L. and Solanum lycopersicum L. Water relations, gas exchange and the differential expression of all aquaporins were analysed. The results showed that cucumber plants under salinity maintained the internal movement of water through osmotic adjustment and the overexpression of specific PIPs aquaporins, following a “conservation strategy”. As tomato has a high tolerance to salinity, the physiological parameters and the expression of most aquaporins remained unchanged. ZnSO4 was shown to be stressful for both plant species. While cucumber upregulated 7 aquaporin isoforms, the expression of aquaporins increased in a generalized manner in tomato. Despite the differences, water relations and transpiration were adjusted in both plants, allowing the RWC in the shoot to be maintained. The aquaporin regulation in cucumber plants facing NaCl+ZnSO4 stress was similar in the two treatments containing NaCl, evidencing the predominance of salt in stress. However, in tomato, the induced expression of specific isoforms to deal with the combined stress differed from independent stresses. The results clarify the key role of aquaporin regulation in facing abiotic stresses and their possible use as markers of tolerance to salinity and heavy metals in plants.

“…Our study aimed to evaluate the response of poplar to NO gas. Soils around Gödöllő (Hungary) have naturally high levels of Zn content (53.3 ± 2.3 mg kg −1 DW soil; Gyulai et al 2012b), and due to the overuse of paraquat in agriculture (Bittsánszky et al 2009), experiments were designed to study zinc and paraquat tolerance of poplars. Primary and secondary soil salinity is also a major environmental hazard not only in Hungary but in the USA and Australia (Csillag et al 1993;Metternicht and Zinck 2003), which is a challenge to study plant salt tolerance (Yamaguchi and Blumwald 2005;Binh et al1992).…”

Phytoextraction potentials of two transgenic (TR) poplar (Populus x canescens) clones TRggs11 and TRlgl6 were compared with that of wild-type (WT) following exposure to paraquat, zinc sulfate, common salt and nitric oxide (NO), using a leaf-disc system incubated for 21 days on EDTA-containing nutritive WPM media in vitro. Glutathione (GSH) contents of leaf discs of TRlgl6 and TRggs11 showed increments to 296% and 190%, respectively, compared with WT. NO exposure led to a twofold GSH content in TRlgl6, which was coupled with a significantly increased sulfate uptake when exposed to 10(-3) M ZnSO4. The highest mineral contents of Na, Zn, Mn, Cu, and Mo was observed in the TRggs11 clone. Salt-induced activity of catalase enzyme increased in both TR clones significantly compared with WT under NaCl (0.75% and 1.5%) exposure. The in silico sequence analyses of gsh1 genes revealed that P. x canadensis and Salix sachalinensis show the closest sequence similarity to that of P. x canescens, which predicted an active GSH production with high phytoextraction potentials of these species with indication for their use where P. x canescens can not be grown.
