For example, sunflowers can absorb uranium, certain ferns have high affinity for As, alpine herbs absorb Zn, mustards can absorb Pb, clovers take up oil, and poplar trees destroy dry-cleaning solvents (New York Times, 2001). Pteris vittata L. can absorb and accumulate high arsenic levels in soil. Arsenite can be oxidized to arsenate in a short time by Pteris vittataroots [15]s . Answer: Pteris vitata can absorbthe arsenic present in the environment. 2 College Kotdwar Pauri Garhwal. 3 IIIM Jammu.

Because the potential of P. vittata to hyperaccumulate As contamination has been This plant could be a practical, wide-ranging tool for soil cleanup. Chinese brake fern (Pteris vittata) can accumulate arsenic during growth. Pteris vittata and Pteris multifida are widely studied As hyperaccumulators that absorb As mainly via roots. This allows the fern to tolerate the otherwise toxic substance. Scientists have discovered a fern that thrives on arsenic. The hyperaccumulator P vittata can take up 4.8 to 5.6 times higher arsenic than the non hyperaccumulator Pteris ensiformis Once taken up, P. vittata is highly efficient in translocating As from the roots, rhizomes and the fronds compared to P. ensiformis which was ineffective in reducing AsV to AsIII (Singh and Ma, 2006). Hence, rhizobacteria exhibit promising potential in phytoextraction owing to their immense microbial diversity and interactions with plants. This plant is being grown in areas surrounding old mines to clean the soil of harmful toxins. As the male and female sex organs have differing maturation times, the sperm seeks a separate individual on which the archegonia are already Wang JR, Zhao FJ, Meharg AA, Raab A, Feldmann J, et al. Environ Exp Bot 50: 243–251. P. vittata can directly absorb arsenite from growth media. It is defined as "the use of green plants and the associated microorganisms, along with proper soil amendments and agronomic techniques to either contain, remove or render toxic environmental contaminants harmless".

Amin Mir 1, Anuj Kumar 2, Abhishek Goal 2 and Priya Singh 3. Brassica rapa is a common field mustard, which has a rapid lifecycle and can be grown under a variety of conditions. The eminence of hyperaccumulators was validated by discovery of the first known As-hyperaccumulating Pteris vittata L. ... Chinese brake fern is very efficient in absorbing As from soil and translocating it from roots to shoots (Ma et al., 2001; Xie et al., 2009). The complexity of this interaction, controlled by climatic conditions, argues against generic and in favor of site-specific phytoremediation approaches. In Pteris vittata fern, however, GAPC1 has a higher affinity for arsenate than phosphate, allowing the plant to grab arsenate and convert it into a compound that OCT4 can then pump into the vacuole for storage, where GST then chemically converts the trapped arsenate into arsenite. Explanation: There are many ferns and shrubs and plant types that can observe different types of pollutants present in environment one such example isPteris vittata, This site is using cookies under cookie policy. (1)being absorb directly by Pteris vittatas;(2) being oxidize to arsenate and then to be absorbed by Pteris vittatas. As(III) uptake is important for the high efficiency of arsenic assimilation, which is the prerequisite for arsenic hyperaccumulation. example, the trichomes of Pteris vittata can absorb the heavy metal arsenic and protect the plant from arsenic contamination (Li et al., 2005a). Phytoremediation cleans up environmental pollution using plants to extract metals from the contaminated soil in the same way a white rose would absorb red food colouring from dyed water and grow red petals. In fact a fern species called Pteris vittata L. can accumulate large amounts of arsenic and the plant has been even commercialized for soil remediation. researches reported that ferns can highly absorb toxic and carcinogenic substances, heavy metals, from contaminated soils, that opened up the possibility for its use for remediation of soils. For example, the Chinese brake fern ( Pteris vittata ) can absorb arsenic from soil. Genetic engineering of the cysteine biosynthesis pathway, involved by AtCYS-3A in leaf trichomes, displays preferable heavy … The plants absorb metals and chemicals – sometimes even changing the pH balance of the soil in the process. • P. vittata grows at less than 1200 m altitudes. Both thallium (Tl) and arsenic (As) bear severe toxicity. Role of Phytoremediation. P. cretica grows between 1200 – 2400 m altitudes. Explanation: There are many ferns and shrubs and plant types that can observe different types of pollutants present in environment one such example is Pteris vittata. Arsenite was transferred to Pteris vittata by two ways, i.e. Tu C, Ma LQ. Edit Summary. The Arsenic Hyperaccumulator Fern Pteris vittata L. ... like stems), which absorb vital nutrients and sufficient water from the surrounding environment. Explanation: There are many ferns and shrubs and plant types that can observe different types of pollutants present in environment one such example isPteris vittata Pteris vittata (brake fern), used to absorb arsenic from the soil Polypodium glycyrrhiza (licorice fern), roots chewed for their pleasant flavor Tree ferns, used as building material in some tropical areas Pteris vittata ferns growing in uncontaminated sites (0.44–7.56 mg kg −1) accumulated between 11.8 mg kg −1 and 64 mg kg −1 in its fronds (Ma et al., 2001). Option - B. The fern uses phosphate ion channels in root cell membranes to absorb and transport the metal to its leaves where it hyperaccumulates and functions as a deterrent to would-be predators. …, explain the 3 ways in which glucose is broken down in human body. PTERIS • Genus Pteris has 280 species distributed in tropical and sub-tropical regions. Consequently, P. vittata encounters a mixed pool of As(V) and As(III) in aerobic environment and P. vittata can directly absorb As(III) from growth medium (Wang et al., 2011). Brake fern (Pteris vittata L.) is well-known for its hyperaccumulation capacity of As, yet its role on Tl accumulation remains unknown. The Chinese fern, whose scientific name is Pteris vittata L, has a "strong capacity" to extract arsenic from the soil, a researcher said. ... pteris vittata is known to be able to absorb high quantities of arsenic from the soil by a process known as ‘hyperaccumulation’. Pteris vittata (brake fern), used to absorb arsenic from the soil Polypodium glycyrrhiza (licorice fern), roots chewed for their pleasant flavor Tree ferns , used as building material in some tropical areas Nearly all arsenic accumu- Nearly all arsenic accumu- lated in the root cells and xylem of P . 3. The purpose of this study was to determine Brassica rapa‘s ability to absorb arsenic and lead from soil. The studies identified two arsenic (As) hyperaccumulators, Pteris vittata and Pityrogramma calomelanos, and four grasses suitable for treatment of lead (Pb)- and zinc (Zn)-contaminated soils, Eleusine indica, Cyperus rotundus, Cynodon dactylon, and Equisetum ramosissimum, of which E. indica was found as Pb hyperaccumulator. 1 Department of Mathematics and Natural Sciences PMU University Al Khobar Kingdom of Saudi Arabia. To clarify the occurrence characteristics of pyrene (PYR) and arsenate (As) as well as their interaction in P. vittata L., the hosting and distribution rules of PYR were determined via two-photon laser scanning confocal microscopy (TPLSCM). An ideal plant for phytoremediation would have a well-developed root system so that it can absorb a large amount of heavy metal ions, and have a large shoot biomass for storage.
