The involvement of exogenous abscisic acid (ABA) concentrations in common bean responses to saline stress was studied in two cultivars iffering in NaCl tolerance. To examine this, salt-sensitive (cv. Coco) and salt-tolerant (cv. Africa) plants in symbiosis with Rhizobium tropici IAT899 strain were grown under controlled conditions and treated with ABA previously to the saline treatment. Plants ...

Salinity is a complex trait that affects growth and productivity in many crops, including rice. Mutation induction, a useful tool to generate salt tolerant plants, enables the analysis of plants with similar genetic background, facilitating the understanding of the salt tolerance mechanisms. In this work, we generated three salt tolerant mutant lines by irradiation of a salt-sensitive cultivar ...

BACKGROUND High salinity (1-10% w/v) of tannery wastewater makes it difficult to be treated by conventional biological treatment. Salt tolerant microbes can adapt to these saline conditions and degrade the organics in saline wastewater. RESULTS Four salt tolerant bacterial strains isolated from marine and tannery saline wastewater samples were identified as Pseudomonas aeruginosa, Bacillus fl...

Iodine is an essential element in the chemical structure of thyroid hormones. The human body requires around 150 g of iodine everyday, which works out to be a teaspoonful (5gm) over a life span of 70 years. Iodine deficiency is the most common cause of brain damage. The magnitude of IDD in India includes 167 million people at risk and goitre is being considered as important public health probl...

Proline accumulation is a common response to salt stress in many plants. Salt stress also increased proline concentration in roots, stems, and leaves of Kosteletzkya virginica seedling treated with 300 mM NaCl for 24 h and reached 3.75-, 4.76-, and 6.83-fold higher than controls. Further study on proline content in leaves under salt stress showed that proline content increased with increasing N...

Salt concentration and pH have dramatic effects on enzymatic catalysis. A quantitative description on these effects is important to elucidate the energetics and mechanisms of catalysis. Here, the effects of salt concentration and pH on binding and catalysis are analyzed with Ribonuclease A (RNase A) as a model system. 11 The effects of pH and mutagenesis on the stability of RNase A-nucleic acid...

Interventions to promote behaviors to reduce sodium intake require messages tailored to local understandings of the relationship between what we eat and our health. We studied local explanations about hypertension, the relationship between local diet, salt intake, and health status, and participants' opinions about changing food habits. This study provided inputs for a social marketing campaign...

We report a systematic study of the condensation of plasmid DNA by oligocations with variation of the charge, Z, from +3 to +31. The oligocations include a series of synthetic linear epsilon-oligo(l-lysines), (denoted epsilonKn, n = 3-10, 31; n is the number of lysines equal to the ligand charge) and branched alpha-substituted homologues of epsilonK10: epsilonYK10, epsilonLK10 (Z = +10); epsilo...

Plant microRNAs (miRs) have emerged as important regulators of gene expression under normal as well as stressful environments. Rice is an important cereal crop whose productivity is compromised due to various abiotic stress factors such as salt, heat and drought. In the present study, we have investigated the role of rice-specific Osa-miR820, in indica rice cultivars showing contrasting respons...

Soil salinity is a common environmental stress factor that limits agricultural production worldwide. Plants have evolved different strategies to achieve salt tolerance. miR393 has been identified as closely related to biotic and abiotic stresses, and targets F-box genes that encode auxin receptors. The miR393-TIR1/AFB2/AFB3 regulatory module was discovered to have multiple functions that manipu...
