The MT-L cDNA clones pECD7, isolated from Mesembryanthemum crystallinum and pCkn16A1 from Nicotiana plumhaginifolia were used to characterize metallothionein-like mRNA expression during cytokinin treatment, copper and NaCI stress.
These data suggest a model in which basipetal auxin transport from a leaf either blocks movement of a growth-stimulatory signal (possibly cytokinin in nature) or initiates a movement of a growth inhibitory signal into the leaf from lower plant organs.
However, young shoot explants cultur ed on medium containing high cytokinin levels lacking ammonium showed typical callus induction patterns.
According to Waaland (1981), the advantages of algae as a biofertilizer are that they: (1) are free of weed seeds and fungal spores which can harm terrestrial crops, (2) are good sources of trace elements, and (3) can regulate crop growth and ripening because of the auxin, cytokinin, and gibberellin associated with them.
