Uranium accumulation in Brassica juncea plant facilitated by calcium in carbonate water
The role of calcium (Ca) on the cellular distribution of U(VI) in Brassica juncea roots and root-to-shoot translocation was investigated using hydroponic experiments, microscopy, and spectroscopy. Uranium accumulated mainly in the roots (727−9376 mg kg−1) after 30 days of exposure to 80 μM dissolved U in water containing 1 mM HCO3 − at different Ca concentrations (0−6 mM) at pH 7.5. However, the concentration of U in the shoots increased 22 times in experiments with 6 mM Ca compared to 0 mM Ca. In the Ca control experiment, transmission electron microscopy−energy-dispersive spectroscopy analyses detected U−P-bearing precipitates in the cortical apoplast of parenchyma cells. In experiments with 0.3 mM Ca, U−P-bearing precipitates were detected in the cortical apoplast and the bordered pits of xylem cells. In experiments with 6 mM Ca, U−P-bearing precipitates aggregated in the xylem with no apoplastic precipitation. These results indicate that Ca in carbonate water inhibits the transport and precipitation of U in the root cortical apoplast and facilitates the symplastic transport and translocation toward shoots. These findings reveal the considerable role of Ca in the presence of carbonate in facilitating the transport of U in plants and present new insights for future assessment and phytoremediation strategies.
Aphid-induced phytochemicals in Brassica juncea (L.) Czern & Coss. afflicting host preference and bionomics of Lipaphis erysimi (Kaltenbach)
<p>Bionomics of an insect and metabolic flux of the host plant are important tools to decipher the status of plant resistance against insect species. This study illuminates vital information on aphid-induced levels of phytochemicals in the siliquae<em> </em>of <em>Brassica juncea</em> cultivars and their effect on host selection and population growth parameters of <em>Lipaphis erysimi</em>. The current study unveiled that the siliquae preference, intrinsic rate of increase (r), finite rate of increase (λ), gross reproductive rate (GRR) and net reproductive rate (R0) were significantly lower on Pusa Mustard 27, DRMR 150-35, RLC 3, NRCHB 101, Pusa Mustard 26 and Pusa Mustard 25. However, mean generation time (T) and doubling time (DT) of <em>L. erysimi</em> were significantly longer (P<0.001) in these genotypes. These cultivars were also found with elevated levels of aphid-induced phytochemicals and their associated enzymes, except in a few cases. Total antioxidants, FRAP, chlorophyll A, total chlorophyll, AO, catalase, PAL and myrosinase were found to contribute 49.18 to 85.30% variation for siliquae preference and bionomics of <em>L. erysimi</em> on the test <em>B. juncea</em> cultivars. The study revealed that phenols, antioxidants, chlorophyll A, chlorophyll B, total carotenoids, AO, APX, PAL, TAL and myrosinase had significant and negative direct consequences on the siliquae preference and bionomics, thus can be exploited as biochemical markers to identify sources of resistance against <em>L. erysimi</em>. Further, DRMR 150-35, NRCHB 101, RLC 3, Pusa mustard 26, RH 749, and Pusa Mustard 27 were found with greater aphid-induced defence phytochemicals and detrimental effects on the host selection and bionomics of <em>L. erysimi</em>, thus can be deployed in <em>Brassica</em> improvement program.</p>
