in order to evaluate the relationships between some traits of iranian rice seedlings under saline conditions,,75 iranian cultivars as traditional, improved and introduced cultivars were used, as a randomized complete block design experiment with 3 replications at rice research institute of iran in three levels of salinity (normal ,1.2 , 4 and 8 ds.m-1) in 2006. root and shoot length, root and s...

in order to study of the effect of priming and salinity on physiological and chemical characteristics of wheat(triticum aestivum l.), an experiment was carried out at the experimental farm of shiraz university. results showedthat primed plants significantly reduced its gas exchanges by accelerating senescence under a series of salt stress,which became more serious along with the increasing of s...

DNA polymerase λ (DNA pol λ) is the only reported X-family DNA polymerases in plants and has been shown to play a significant role in dry quiescent seeds, growth, development and nuclear DNA repair. cDNA for DNA pol λ has been reported in Arabidopsis and japonica rice cultivar and has been characterized from E. coli expressed protein, but very little is known about its activity at protein level...

the objective of this study was evaluation of salt tolerance of elite forage sorghum lines in laboratory and field conditions. salinity treatments were 5, 10, 15, 20, 25, 30 decisimens per meter in laboratory and distilled water as control. lines were kfs1, kfs2, kfs3, kfs4, mfs1, mfs2 and lfs56. the lines also cultivated in saline and non saline field conditions during 2004-2005. electrical co...

The response of Spirulina platensis cells to salinity stress was studied. Once adapted to the higher osmoticum, photosynthetic parameters such as the maximum rate of photosynthesis under saturating irradiance (Px) and the initial slope of the P-I curve (a) are reduced by 15% and 25% in 0.5 M NaCl grown cells, respectively. Salt-adapted cells have a modified biochemical composition; reduced prot...

Epizootics of an infectious cuticular epithelial necrosis virus (ICENV) occurred in cultured Penaeus vannamei in Ecuadorian shrimp farms from 1994 to 1996. There were few reports of outbreaks during 1997, but in the second half of 1998 epizootics were again reported. Histopathological examination revealed extensive tissue changes and necrosis as described for infections by what others have call...

Physical and chemical boundaries for microbial multiplication on Earth are strongly influenced by interactions between environmental extremes. However, little is known about how interactions between multiple stress parameters affect the sensitivity of microorganisms to antibiotics. Here, we assessed how 12 distinct permutations of salinity, availability of an essential nutrient (iron) and atmos...
