Salinity
Genetic analysis of NaCl tolerance in tomato
Authors: A. Saeed, M.Q. Shahid, S.A. Anjum, A.A. Khan, A. Shakeel, M.F. Saleem and N. Saeed
We attempted to find the suitable parents for the development of tomato hybrids for high salt soils by exploiting combining ability, gene action and heterosis. Six salt-tolerant and three salt-intolerant genotypes, along with their 18 F1 crosses, were evaluated at seedling stage under 10 and 15 dS/m (NaCl) salinity stress, com.. Read More»

Evaluation of wheat landrace genotypes for salinity tolerance at vegetative stage by using morphological and molecular markers
Authors: A. Shahzad, M. Ahmad, M. Iqbal, I. Ahmed and G.M. Ali
Identification of new sources of salt tolerance is particularly important to develop crop varieties suitable for saline soils. We evaluated 129 Pakistani and 58 exotic wheat landraces/cultivars grown in Hoagland’s hydroponic nutrient solution, under control (tap water equivalent to 10 mM salt) and salt stress (200 mM NaC..

mRNA expression profiles of heat shock proteins of wild and salinity-tolerant swimming crabs, Portunus trituberculatus, subjected to low salinity stress
Authors: X.N. Bao, C.K. Mu, C. Zhang, Y.F. Wang, W.W. Song, R.H. Li and C.L. Wang
Challenged by the low salinity, 4 parts per thousand (4 ppt), for 72h, the survivals of swimming crabs (Portunus trituberculatus) were collected as the screened group (SG, tolerant to low salinity). Aiming at identifying the mechanism of low salinity tolerance, quantitative real-time PCR was employed to investigate the express.. Read More»

Effects of exogenous 5-aminolevulinic acid on photosynthesis, stomatal conductance, transpiration rate, and PIP gene expression of tomato seedlings subject to salinity stress
Authors: Y.Y. Zhao, F. Yan, L.P. Hu, X.T. Zhou, Z.R. Zou and L.R. Cui
The effects of exogenous 5-aminolevulinic acid (ALA) on photosynthesis, plant growth, and the expression of two aquaporin genes in tomato seedlings under control and salinity conditions were investigated. Exogenous ALA application significantly improved net photosynthetic rate (Pn ), total chlorophyll content, and plant biomass accumulation of tomato seed.. Read More»

Application of denaturing gradient gel electrophoresis for detection of bacterial and yeast communities along a salinity gradient in the estuary of the Cachoeira River in Brazil
Authors: C.S.P. Rodrigues, S.S. Souza, R.P. Rezende, A. Silva, J.L. Andrioli, H. Costa, R. Fontana and J.C.T. Dias
An estuary is a transition zone between freshwater and marine ecosystems, resulting in dilution of seawater. Estuaries are also considered environments of intense biological activity related to the processes of nutrient cycling. The aim of this study was to evaluate the microbial community composition along a salinity gradient in the estuary of the Cachoe.. Read More»

Expressed sequence tag-simple sequence repeat-based molecular variance in two Salicornia (Amaranthaceae) populations
Authors: Z.L. Xu, Z. Ali, J.X. Yi, X.L. He, D.Y. Zhang, G.H. Yu, A.A. Khan, I.A. Khan and H.X. Ma
Salicornia spp is one of the most salt-tolerant vascular plants and is native to salt marshes and estuaries. We developed expressed sequence tag derived-simple sequence repeat (EST-SSR) markers for estimating genetic diversity and marker-assisted Salicornia breeding. Six polymorphic EST-SSRs of 40 detected 27 alleles, ranging .. Read More»

Proline accumulation is a general response to abiotic stress in the date palm tree (Phoenix dactylifera L.)
Authors: M.W. Yaish
Plants exposed to certain abiotic stress conditions tend to produce the amino acid proline, which acts as an active osmolyte, a metal chelator, an antioxidant, and a signaling molecule. There is increasing evidence that proline accumulates in plants due to a wide range of abiotic stress, in particular high soil salinity and drought. Therefore, proline con.. Read More»

Differential expression of TLP, ERF1, and R2R3MYB in annual Medicago species under salinity conditions
Authors: F. Gharaghani, F. Rafiei, N. Mirakhorli and E. Ebrahimie
The present study was conducted to evaluate the responses of three annual Medicago species (M. truncatula, M. laciniata, and M. polymorpha) to salinity. We analyzed publicly available microarray data in NCBI pertaining to salinity-response genes in M. truncatula. Our data search identified Tubby C2 (TLP) and ethylene responsive transcription factor 1 (ERF.. Read More»
