Cheiran thus cheiri wall flowerIberis amara candituft Lobularia, Matthiola stockHesperis rocketAlyssum, Lunaria honesty etc. In contrast to the more common reports with other metals, Gupta et al. Stem leaves present; base sessile but not auriculate or amplexicaul, or auriculate, amplexicaul, or sagittate; divisions and margins entire or repand, or dentate, serrate, incised, crenate, sinuate. Camelina Annual or biennial; herbs; terrestrial; thorns and spines absent; hairs trichomes a mixture of simple and branched, or at least some dendritic tree-like ; multicellular glands absent; not a weed, or a weed. Fruit a silique fruit more than 3 times longer than broad ; linear, or oblong; latiseptate flattened parallel to septumor terete not flattened, cylindrical circular in cross sectionor quadrangular 4-angled square or rectangular in cross section ; fruit or segments wall neither woody or papery normal ; dehiscent readily releasing seeds ; gynophore at least 1. Iberis amara is used in rheumatism and gout.
There is an increasingly large body of literature describing the effects of heavy metals in different Brassica species, confirming the relatively high tolerance that they have towards this abiotic stress, however the exact mechanism for this tolerance remains to be fully clarified [ 616 ]. Brassica juncea Indian mustard is important in oil production, has medicinal properties and is used as a condiment. Powell, M. The experiments in soil are usually more complex as the number of variables affecting heavy metal uptake also increase like soil type, pH, organic matter etc.
Fruits are capsules that open with two valves, usually towards the top. Petals subequalling sepals; white; obovate; margin and apex entire. The family includes genera and species according to Willis. Petals distinctly longer than sepals, or subequalling sepals, or absent; white; obovate, or oblong to elliptic, or spatulate to oblanceolate; margin and apex entire. The experiments in soil are usually more complex as the number of variables affecting heavy metal uptake also increase like soil type, pH, organic matter etc. Fruit segmentation not segmented.

In two publications Quartacci et al. Hahn, S. Stamens six; lower part of filaments and petal claws without anything; filaments of median stamens free.
Stamens six; lower part of filaments and petal claws without anything; filaments of median stamens united at least along lower third; stamens included within calyx or partially exserted.
Roots: Tap root, swollen on account of stored food materials. Whitten, K. Nixon, and J. Another explanation given is the increase in the induction of metal transporters involved in vacuolar sequestration and the increase in the expression of genes that are involved in the synthesis of glutathione and phytochelatins see below.
One of the problems regarding the applicability of plants for phytoremediation purposes is the difficulty in establishing representative experimental setups. Leaves alternate. There is effect of sulphate on the establishment of two members of Brassicaceae book increasingly large body of literature describing the effects of heavy metals in different Brassica species, confirming the relatively high tolerance that they have towards this abiotic stress, however the exact mechanism for this tolerance remains to be fully clarified [ 616 ].
Although the general response to the evaluated parameters was similar, some cultivars presented higher Cd tolerance than others.
Therefore, the exact mechanisms through which plants get rid of excess hydrogen peroxide is highly dependent not only of the species but on all the different exogenous factors affecting the experiment although at least one of these enzymes is usually found to increase its activity.
Many of these have sticky seed coats, assisting long distance dispersal by animals, and this may also explain several intercontinental dispersal events in the genus, and its near global distribution. Minglin et al. Afghanistan, or Tajikistan. Petals distinctly longer than sepals; white; obovate, or orbicular; margin and apex entire.
From Table S2 we can see that there is a general trend for the increase in SOD activity in different Brassica species and different metals, although there are some exceptions, but the subsequent decomposition of hydrogen peroxide to water seems to be more genera and metal dependent.
Portland, OR: Timber Press. In Table S2 we present selected results of the reported activities of enzymes involved in the antioxidative stress defense mechanisms. A frequently described effect of metal toxicity is the increase in the levels of citrate and this seems to be an important factor in heavy metal tolerance in these plants, as this organic acid could be implicated in chelating the metals facilitating its translocation and accumulation in the shoots and reducing its toxicity.
Soltis, D.Feb 01, · The Brassicaceae Family Shows Aberrant Shoot-Skewed NLR Gene Expression. To determine which of these contrasting patterns of NLR gene expression was predominant among flowering plants, we analyzed additional species for which root and shoot tissues had been subjected to global expression profiling in the same magicechomusic.com by: 6.
