“…Some of these soils are so rich in Zn that excess of this nutrient becomes a major factor limiting plant growth (Ernst 2006) and only some plants were able to adapt to such extreme environments (e.g. Przedpelska and Wierzbicka 2007;Abratowska et al 2012). It is highly probable that Zn metabolism and the impact of this metal on physiological processes could be different in plants from Zn-poor and Zn-rich soils.…”

We investigated the impact of low zinc (Zn) concentrations in the substare on the onset of flowering in Arabidopsis arenosa (Brassicaceae). Experiments were carried out in controlled conditions using plants from four different populations. The research was aimed to verify experimentally the following hypotheses: (1) Zn content in the growth medium promote the onset of flowering in A. arenosa, (2) Changes in the onset of flowering induced by Zn depend on Zn concentration employed; (3) Zn-induced early onset of flowering is an universal plant response present within the species and is not an effect of stress or physiological adaptation to high Zn content in the environment. Investigated plants were subjected to four different Zn concentrations: 0.4 (control), 155, 775 and 1,550 lM Zn 2? . To asses stress level in investigated plants we calculated biomass accumulation and employed fluorometric methods. Zn content was estimated in shoots using atomic absorption spectroscopy. Differences in the onset of flowering were assessed using Kaplan-Meier curves. Our results showed that Zn was transported form growth medium to roots and shoots of investigated plants and that the content of Zn increased with the increase of Zn concentration in the growth medium. We evidenced that apart from one (1,550 lM Zn 2? ) applied Zn concentrations did not caused stress in investigated plants what was confirmed by two independent experimental approaches: measurement of biomass accumulation and chlorophyll a fluorescence. Flowering curves obtained on the basis of calculation of Kaplan-Meier estimator showed that: (1) control plants originating from four different populations did not differ in terms of the onset of flowering, (2) plants from each population tested tends to enter flowering phase earlier in response to applied Zn concentrations than control plants, (3) plants treated with the lowest tested Zn concentration (155 lM Zn 2? ) tend to flower earlier than plants treated with the higher concentration (775 lM Zn 2? ), (4) the impact of Zn on the onset of flowering did not depend on the origin on the plant material used (Zn-rich or Zn-poor soils). Our results indicate that Zn ions present in the growth medium promote early flowering in A.arenosa and that this effect may depend on Zn concentration used. Zn-induced early flowering in A. arenosa seems to be an universal plant response present within the species and is not an effect of stress or physiological adaptation to high Zn content in the environment.

“…MetAFLP platforms proved to be a valuable tool for analyzing changes induced by cryopreservation in Gentiana cruciata tissue (Mikuła et al 2011), or for evaluating the genetic distinctiveness of metallicolous and non-metallicolous populations of Armeria maritime (Abratowska et al 2012). Population genetic analysis of Poa annua (Chwedorzewska and Bednarek 2012) demonstrated that the approach could be used to extract information on epigenetic variation even in the case of population studies.…”

Extended metAFLP approach in studies of tissue culture induced variation (TCIV) in triticale

We present the development of the theoretical background of the metAFLP approach which allows for partition of complex variation into sequence changes, de novo methylation and demethylation of the regenerants derived via in vitro tissue culture methods in the case of triticale. It was demonstrated that, independent of whether andro- or embryogenesis was used for plant regeneration, the level of sequence changes identified between regenerants is about 10 %. Moreover, DNA demethylation prevails over de novo methylation of the regenerants compared to the donor plant. The metAFLP approach allows for the evaluation of numerous quantitative characteristics. For instance, one may quantify the number of sites unaffected by tissue culture approaches, global site DNA methylation etc. It is suggested that the approach could be useful for breeders in order to control plant material uniformity or for the evaluation of modified in vitro tissue culture approaches allowing for control of the (epi)mutation level. The extended metAFLP approach presented here delivers sufficient background for the evaluation of software that could facilitate analyses of the tissue culture induced variation.Electronic supplementary materialThe online version of this article (doi:10.1007/s11032-014-0079-2) contains supplementary material, which is available to authorized users.

“…In addition, nickel could lead to modification missing in histone H2A, H2B, H3, and H4, and bring about increased demethylation of H3K9 and generally improved ubiquitination level of H2A and H2B [16,17,18,19,20,21,22,23,24]. The plant genomic DNA changed and rapidly responded to the environmental stress such as chilling, salts, heavy metal and pollutants [25,26,27]. The heritable methylation and phenotypic variations in these responses have been much vital for the research of plant breeding.…”

Background: In recent years, nickel (Ni) has been widely applied in industrial and agricultural production and has become a kind of environmental pollution. In this study, the effect of nickel chloride (NiCl 2 ) with different concentrations on Arabidopsis genomic stability and DNA methylation has been demonstrated. The nucleolus variation and 18S rDNA methylation after NiCl 2 treatment have been analyzed.Results: The results are as follows: (1) The NiCl 2 could result in heritable genomic methylation variations. The genomic DNA methylation variations have been detected by methylation-sensitive amplified polymorphism (MSAP) molecular markers, and the result showed that after NiCl 2 treatment, there was methylation variation in T 0 generation seedlings, and partial site changes maintained in T 1 generation, which suggested that the effects of NiCl 2 on DNA methylation could be heritable in offspring. (2) NiCl 2 brought deformity and damage to nucleolar structure in Arabidopsis root tip cells, and the damage was positively correlated with the NiCl 2 concentration. 3. In the nucleolus, there was an increased cytosine methylation in 18S rDNA. The plant nucleolus variation and 18S rDNA methylation may be used as an examination indicator for Ni pollution in soil or plant. Conclusions: NiCl 2 application caused variation of DNA methylation of the Arabidopsis genomic and offspring's. NiCl 2 also resulted in nucleolar injury and deformity of root tip cells. The methylation rate of 18S rDNA also changed by adding NiCl 2 .
