Protonema of the moss Funaria hygrometrica can function as a lead (Pb) adsorbent
Water contamination by heavy metals from industrial activities is a serious environmental concern. To mitigate heavy metal toxicity and to recover heavy metals for recycling, biomaterials used in phytoremediation and bio-sorbent filtration have recently drawn renewed attention. The filamentous protonemal cells of the moss Funaria hygrometrica can hyperaccumulate lead (Pb) up to 74% of their dry...
متن کاملKinetin & Kinetin Analogues as Substrates & Inhibitors of Xanthine Oxidase.
The discovery of the stimulation of cell division in plant tissues by trace amounts of kinetin, 6(2-furfuryl) aminopurine (11), has resulted in a number of investigations concerned with the effects of this and related compounds on a variety of plant and animal systems (4, 5, 7,9, 10, 12, 13). One system, developed for study of the in situ effect of agents upon the maintenance of normal organiza...
متن کاملInternal Water Status of Kinetin-treated, Salt-stressed Plants.
Stomatal resistances and turgor pressures were measured during a 12-day period on leaves of bean (Phaseolus vulgaris L. cv. Contender) which were treated with kinetin, were salinized or were treated with kinetin and salinized. Stomatal resistances were highest in salt-stressed plants, and progressively lower in salt-stressed and kinetin-treated plants, control plants, and kinetin-treated plants...
متن کاملVisualization of the endoplasmic reticulum in living buds and branches of the moss Funaria hygrometrica by confocal laser scanning microscopy
Caulonemata of the moss Funaria hygrometrica were vitally stained with the fluorescent, lipophilic carbocyanine dye DiOC6(3) and examined via confocal laser scanning microscopy. Although DiOCfi(3) stained nearly all of the organdies, cortical endoplasmic reticulum (ER) could be resolved under favorable conditions and appeared as a network of irregular polygons, interspersed with lamellar cister...
متن کاملThe effect of 1,4-dihydropyridines on the initiation and development of gametophore buds in the moss funaria.
The plant hormone cytokinin stimulates target caulonemata of Funaria to form buds that develop into the leafy gametophyte. Previous reports have shown that increases in intracellular Ca(2+) occur during hormone-activated budding concomitant with an alteration in the polarity of the organelles in the bud site. In order to ascertain the involvement of voltage-dependent Ca(2+) channels in this phe...
