Growth and physiological adaptation of whole plants and cultured cells from a halophyte turf grass under salt stress
Understanding the mechanisms used by halophytic members of the Poaceae to cope with salt stress will contribute to the knowledge necessary to genetically engineer salt-tolerant crops. In this study, we identified a genotype of Sporobolus virginicus, a halophytic turf grass collected in Japan, and investigated its growth rate, ion concentration and secretion, and proline concentration in compari...
متن کاملComparative Activity of Isomers of Zeatin and Ribosyl-Zeatin on Funaria hygrometrica.
The activities of isomers of zeatin, ribosyl-zeatin, and 6-(gamma,gamma-dimethylallylamino) purine (i(6)Ade) on the moss Funaria hygrometrica are compared by measuring the ability of the cytokinins to induce callus or gametophores. The cis- and trans-ribosyl-zeatins were inactive, and therefore this kind of bioassay cannot be used as evidence for the presence or absence of a cytokinin in tests ...
متن کاملDetermination of Some Heavy Metals Levels in Funaria Hygrometrica in Dutsinma Town of Katsina State, Nigeria
The levels of some heavy metals were determined in Funaria hygrometrica (moss plant) harvested from the streets of Dutsinma town of Katsina State of Nigeria using atomic absorption spectrometry. Over the years the town has witnessed influx of people from neighbouring villages, as a Local government headquarters. The mean level of the metals in the study area varied between Cd (0.06μgg and 0.43μ...
متن کاملProtonema 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 کاملDehydration protection provided by a maternal cuticle improves offspring fitness in the moss Funaria hygrometrica.
BACKGROUND AND AIMS In bryophytes the sporophyte offspring are in contact with, nourished from, and partially surrounded by the maternal gametophyte throughout their lifespan. During early development, the moss sporophyte is covered by the calyptra, a cap of maternal gametophyte tissue that has a multilayered cuticle. In this study the effects on sporophyte offspring fitness of removing the mat...
