LITERATURE
BjSMT responds to selenite [Se(IV)] and selenate [Se(VI)] stress in Brassica juncea. BjSMT expression is nearly undetectable in the Brassica juncea plant without Se exposure, but in the plant leaves it can be rapidly and significantly upregulated upon a low level of selenite stress, and enormously upregulated upon selenate treatment
-
concentrations higher than 40 microM show a negative effect on BoSMT mRNA accumulation. At very high selenate concentrations e.g. 100 microM, the expression of BoSMT mRNA substantially reduced
high sulfate levels in growth medium significantly reduce accumulation of BoSMT transcripts in plants
selenocysteine methyltransferase gene expression and antioxidant enzyme activities in Astragalus chrysochlorus are selenium-induced. Transcript level of callus tissues grown at 0.0052 mM and 0.0264 mM Se-enriched media is lower than that of the control callus. In contrast, a high level of Se (0.132 mM) in the medium causes an approximately 4.26times higher level of SMT transcript in callus than the control
-
treating Brassica oleracea plants with selenate results in a rapid accumulation of BoSMT mRNA and reaches a maximum expression at selenate levels between 20 and 40 microM. This is in contrast to 40 microM selenite, which causes only a slight accumulation of the transcript
