Methylselenocysteine (MeSeCys) is an amino acid derivative that possesses potent anticancer activity in animals. Plants that can tolerate growth on soils with high Se content, known as Se hyperaccumulators, do so by converting inorganic Se to MeSeCys by the enzyme selenocysteine methyltransferase (SMT). A cDNA encoding the SMT from a Se hyperaccumulator was(More)
Corpse morphology, nuclear DNA fragmentation, expression of senescence-associated genes (SAG) and cysteine protease profiles were investigated to understand cell death patterns in a cell cycle-synchronised Arabidopsis thaliana cell suspension culture treated with four physiological stressors in the late G2 phase. Within 4 h of treatment, polyethylene glycol(More)
The current study examines the transcription of four genes (BoCAR1A, BoCAR5, BoCAR6-4 and BoCAR25) found to be up-regulated in response to high CO(2)/low O(2) treatment in broccoli (Brassica oleracea). Messenger RNA levels for the four genes declined after tissues were removed from CA. Physiological and biochemical changes and gene expression patterns were(More)
