abstract：:The uptake of liposomal contents into Catharanthus roseus protoplasts has been quantitated. Hi.phest uptake was obtained from positively charged vesicles (1.09% of vesicle contents per 10(7) protoplasts) in the presence of 10% w/v polyethylene glycol 4000. Significant uptake was also observed from negatively charged v...

abstract：:Two kinds of effects of water stress on flag leaves of spring wheat (Triticum aestivum L. cv. Kolibri) were recognized: the direct effect, when drought affected the expanded blade of the flag leaf and the indirect one, when drought pretreatment affected the leaf blade during tissue differentiation. As a direct effect ...

abstract：:In the highly vacuolated epidermis cells of leaf explants of Nautilocalyx we investigated whether inhibition of cytokinesis by 2,6-dichlorobenzonitrile (DCB) could be caused by a suppression of the formation of phragmosome and band of microtubules (BMT), two structures which are probably involved in cytokinesis and in...

abstract：:Change of extracellular ion concentration in the main pulvinus of Mimosa pudica L. during a slow downward movement induced by white light (0.24 mW cm(-2)) was investigated using K(+)- and Cl(-)-selective electrodes and a pH electrode. The photostimulation induced a transient and concurrent efflux of K(+) and Cl(-) fro...

abstract：:Half-lives of tRNA and the initial rates of tRNA accumulation are correlated with the growth rates of cell suspension cultures of Lupinus angustifolius cv. Turkus and Petroselinum hortense cv. Berlinska. Half-lives of tRNA are approximately proportional to the doubling times of cells in these cultures. The initial rat...

abstract：:Somatic embryogenesis was initiated in immature embryos of rye (Secale cereale L.) cultured on Murashige and Skoog's (1962) medium supplemented with various concentrations of 2,4-D and sucrose. The developmental stage of the embryo (optimal embryo length 0.5-2.0 mm) and concentration of 2,4-D (optimal concentration 2....

abstract：:Chlorophyll-oxidase in barley thylakoids was activated by linolenic acid. The reaction products from endogenous chlorophylls were investigated by thin layer and high performance liquid chromatography. Within 2-10 min a new pigment was formed which migrated identically with authentic 13(2)-hydroxychlorophyll a (1a). Af...
