A new pregnane glycoside, 3-O-beta-lycotetraosyl 5alpha-pregna-3beta,26beta-diol-20-one was isolated from overripe tomato, the fruit of Lycopersicon esculentum MILL.

conclusions the vermicompost as a potential source of plant nutrients for sustainable tomato production can reduce health and environmental problems. results the analysis of the variance results revealed that the effect of the type and amount of fertilizers on tomato yield was significant at 1% level. the results of this study showed that using the vermicompost dosage to cow manure of 500 g/m2 ...

The 45S and 5S rDNA loci were physically mapped by double-probe FISH on mitotic metaphase chromosomes in the six strains of F. esculentum tataricum. Results showed that tataricum very small similar. diploid karyotype formulas these two species 2n=2x=16=12m+4m (SAT) 2n=2x=16=12m+4sm (SAT), respectively. Four pairs IS, IIS, IIIL, VL, as well IL IVS esculentum, five VIIS, three IL, IVS, VIS There ...

The diuretic activity of methanol extract of Oxystelma esculentum aerial parts (MEOE) was studied in male Wister albino rats at 5h and 24h interval. The animals were divided into 5 groups: control, urea, furosemide and 200mg/kg and 400mg/kg MEOE. The extract was administered intraperitoneally (i.p) pretreated and all animals were saline MEOE. The urine volume (in mL) and electrolytes excretio...

Regeneration and gene expression of salt/drought stress tolerant Alhagi graecrum and stress sensitive Lycopersicon esculentum under different concentrations of NaCl and mannitol were studied. Mannitol and NaCl applied at concentrations of 86, 172, 256 and 43, 86, 172 mM, respectively, in a shoot regeneration medium, caused similar water potentials. In L. esculentum, regeneration was influenced ...

background: lead, an example of heavy metals, has, for decades, being known for its adverse effects on various body organs and systems such that their functions are compromised. objective: in the present study, the ability of lycopersicum esculentum on decrease toxic effects of lead acetate on plasma superoxide dismutase, catalase and malondialdehyde in rat. lead to adversely affect the liver t...

Leaf mesophyll protoplasts of Lycopersicon esculentum were fused with suspension-culture-derived protoplasts of Solanum lycopersicoides by a PEG treatment. Both species have the same chromosome number (2n = 2x = 24). The hybrid calli were selected using the full selection method - kanamycin resistance and culture conditions critical for L. esculentum protoplast divisions. The genomic in situ hy...

The vascular tissue of higher plants is organized into a continuous and unified system that undergoes a transition between two highly differentiated structures, the root and the shoot. This transition was studied in tomato by investigating the genetic basis of morphological variation between Lycopersicon esculentum and L. hirsutum LA407. Our analysis concentrated on morphology in stem cross sec...

Glutamine synthetase was localized in leaves and cotyledons of young tomato (Lycopersicon esculentum Mill.) plants using immunogold techniques coupled to transmission electron microscopy. The enzyme occurs only in chloroplasts and is most probably a stroma constituent.
