Physiological response of Solanum nigrum to salt stress

Physiological response of Lactobacillus plantarum to salt and nonelectrolyte stress.

In this report, we compared the effects on the growth of Lactobacillus plantarum of raising the medium molarity by high concentrations of KCl or NaCl and iso-osmotic concentrations of nonionic compounds. Analysis of cellular extracts for organic constituents by nuclear magnetic resonance spectroscopy showed that salt-stressed cells do not contain detectable amounts of organic osmolytes, whereas...

Salinity stress enhances production of solasodine in Solanum nigrum L.

Various in vitro grown tissues (non-regenerative callus, regenerative callus and microshoot derived leaves) of Solanum nigrum L. were cultured under salinity stress (0-150 mM NaCl) for enhanced production of solasodine, a steroidal alkaloid and an alternative to diosgenin, which is used as a precursor for the commercial production of steroidal drugs. The role of plant growth regulators and vari...

Response of Two Indica Rice Varieties to Salt Stress

  Salinity is one of the most challenging problems that adversely affects growth and development of plants. Therefore, understanding of the mechanisms that enable plants to adapt to salinity stress will ultimately help in the selection of stress tolerant cultivars for exploiting saline soils. The main objective of this study was to examine the effects of NaCl on some physiological and biochemic...

Antimicrobial activity of fruits of Solanum nigrum and Solanum xanthocarpum.

Current study was conducted to investigate antimicrobial activity of fruit extracts of two Solanaceous plants (Solanum nigrum and Solanum xanthocarpum) found in Pakistan. Petroleum ether, chloroform, dichloromethane, ethyl acetate, acetone, methanol and water were utilized for extraction. The highest percentages of polar components of both the species were extracted by water; little amount of n...
