Eleven salt tolerant bacteria isolated from different sources (soil, plants) and their transformed strains were used to study their influence on Triticum aestivum var. Inqlab-91 growth under salt (100 mM NaCl) stress. Salt stress caused reduction in germination (19.4%), seedling growth (46%) and fresh weight (39%) in non-inoculated plants. In general, both wild and transformed strains stimulate...

a two years (2006–2007 and 2007-2008) experiment was conducted at national salinity research center, yazd, to evaluate salt-tolerant genotypes of brassica napus, b. rapa and b. juncea. to screen genotypes in the first growing season, 58 genotypes were grown under two irrigation water salinity levels of 2 and 12 ds m-1 in an augmented randomized complete block design with six replicated checks. ...

Repetitive rounds of differential subtraction screening, followed by nucleotide sequence determination and northern-blot analysis, identified 84 salt-regulated (160 mM NaCl for 4 h) genes in Arabidopsis wild-type (Col-0 gl1) seedlings. Probes corresponding to these 84 genes and ACP1, RD22BP1, MYB2, STZ, and PAL were included in an analysis of salt responsive gene expression profiles in gl1 and ...

The existing question whether ethylene is involved in the modulation of salt-induced cell death to mediate plant salt tolerance is important for understanding the salt tolerance mechanisms. Here, we employed Arabidopsis plants to study the possible role of ethylene in salt-induced growth inhibition and programmed cell death (PCD) profiles. The root length, DNA ladder and cell death indicated by...

BACKGROUND AND AIMS In Tunisia, salt water is largely used for tomato irrigation. In this work, a study was made of the changes in the nitrate reduction and ammonium assimilation into amino acids in tomato seedlings under salinity in order to providee further insight into the salt effects on plant growth. Methods Ten-day-old tomatoes (Solanum lycopersicum) were subjected to 100 mm NaCl stress, ...

This study was carried out to study the proteome of date palm under salinity and drought stress conditions to possibly identify proteins involved in stress tolerance. For this purpose, three-month-old seedlings of date palm cultivar "Sagie" were subjected to drought (27.5 g/L polyethylene glycol 6000) and salinity stress conditions (16 g/L NaCl) for one month. DIGE analysis of protein extracts ...

Stress-induced proline accumulation in plants is thought to result primarily from enhanced proline biosynthesis and decreased proline degradation. To identify regulatory components involved in proline transport, we screened for Arabidopsis thaliana T-DNA mutants with enhanced tolerance to toxic levels of exogenous proline (45 mM). We isolated the proline resistant 1-1 (pre1-1) mutant and map-ba...

Salinity is one of the most important problems that restrict cultivation of crops in arid and semi-arid regions. Pistachio (Pistacia vera L.) is one of the most important trees that grow in these restricts. In this greenhouse study, the effects of salinity on growth of pistachio rootstock Badami evaluated. Seedlings were grown in plastic bags containing perlite. Salinity was imposed, by adding ...
