“…In the present study, acute Zn stress did not induce PC production, neither in the roots nor the shoots of the M and NM ecotypes of D. carthusianorum, in accordance with the results reported for Sedum alfredii (Sun et al 2005) and Armeria maritima (Olko et al 2008), indicating that other mechanisms must be crucial for Zn detoxification. Although an important role of PCs was suggested for Zn detoxification in Arabidopsis thaliana (Tennsttedt et al 2009;Sofo et al 2013), comparative studies of Zn-tolerant and -sensitive lines of Silene vulgaris showed higher PC accumulation in the sensitive line, arguing at least against their role in enhanced Zn tolerance (Harmens et al 1993;Schat et al 2002).…”

“…Similarly, the metallicolous population of Armeria maritima responded to Zn excess with a higher increase in the GSH level than the nonmetallicolous one (Olko et al 2008). In contrast to these results, no significant variation in the GSH levels was observed in the roots of the Zn-treated D. carthusianorum, whereas a decrease in the GSH concentration was found in the shoots of the M ecotype at the highest Zn treatment.…”

“…The chromatograms were recorded and analysed using 32 Karat 7.0 software (Beckman, Fullerton, USA). Organic acids were analysed spectrophotometrically as described by Olko et al (2008) (for the hydroponic experiment) and by capillary electrophoresis (CE) as described by Dresler et al (2014) (for the soil experiment).…”

“…Among them, intraspecies investigations of Zn tolerance have also been conducted on several species occurring in both metalliferous and non-metalliferous habitats (Thurman and Rankin 1982;Harmens et al 1993Harmens et al , 1994Köhl 1997;Bert et al 2000;Sun et al 2005;Deng et al 2007;Olko et al 2008;Colzi et al 2014). These studies were mainly focused on plants exposed to acute short-term metal stress in hydroponic cultures.…”

Physiological mechanisms of adaptation of Dianthus carthusianorum L. to growth on a Zn-Pb waste deposit - the case of chronic multi-metal and acute Zn stress

Aims This study investigates the response of metallicolous (M) and nonmetallicolous (NM) ecotypes of Dianthus carthusianorum L. to chronic multi-metal and acute Zn stress. Methods Plants were cultivated on the Zn-Pb waste heap substrate and under Zn excess in hydroponics. Growth parameters as well as accumulation of organic acids and thiol peptides were determined as a function of metal accumulation. Results When grown on the metalliferous substrate, the M plants showed less phytotoxicity symptoms, lower foliar metal (Zn, Pb, Cd) accumulation, higher malate and citrate but lower glutathione content than the NM plants. When exposed to Zn excess in hydroponics, the M ecotype was also more tolerant but accumulated more Zn in comparison with the NM ecotype, accompanied by greater malate and citrate concentrations in the shoots, which were however not affected by increasing Zn doses. No phytochelatins were detected under any experimental conditions. Conclusions Both constitutive and adaptive tolerance was found in D. carthusianorum. Under chronic metal stress, enhanced tolerance results from restricted metal uptake to the shoots and probably from detoxification by organic acids; however, under acute Zn stress it is not related to diminished metal uptake or organic acids. Glutathione and phytochelatins are not implicated in adaptive metal tolerance.

“…The formation of new plant forms in anthropogenic habitats has been also discussed with reference to areas heavily polluted with heavy metals, such as zinc-lead dumps (e.g. Przedpełska and Wierzbicka 2007;Olko et al 2008;Wierzbicka and Panufnik 1998;Załęcka and Wierzbicka 2002;Wierzbicka and Pielichowska 2003), which has been recently confirmed in genetic studies (Abratowska et al 2012).…”

Geranium robertianum L., plant form adapted to the specific conditions along railway: “railway-wandering plant”

The question of whether any specific plant species are typically growing along railway tracks (the socalled ''railway-wandering plants'') has been discussed for many years. This study proves the existence of a form of Geranium robertianum species growing along railway tracks in North-Eastern Poland. Floristic studies have been carried out in 246 areas along railway tracks. This particular species was found in 70 studied areas (28 %). Comparative studies were carried out on 12 plant populations growing in the fieldwork and in glasshouse cultivation. Plants growing along the railway tracks in Waliły were different from all other studied populations. They were small (smaller by 31 %, max. by 57 % than other plants), with little leaf blades representing different shapes and colour. In studies of light absorption by photosynthetic apparatus (chlorophyll fluorescence) under conditions of exposure to high light intensity, the plants from Waliły were proved to have a better adaptation capacity to stress conditions. Increased levels of anthocyanins-which provided better protection of the photosynthetic apparatus against insolation-were shown. The protective properties against water deficiencies and excessive insolation were genetically preserved and were found in the second generation of plants cultivated in a glasshouse. For the first time, a new plant form of G. robertianum-a ''railway-wandering plant'' adapted to the conditions prevailing along railway tracks-was confirmed to exist. The form has developed probably after 1886, when the Białystok-Zubki railway was built, featuring the Waliły railway station.
