Drought induced stress is one of the most significant environmental challenges. This study was designed to evaluate the effects of drought stress on crop yield and antioxidant systems during the vegetative period of wheat. The study was carried out in a greenhouse using factorial experiment based on complete randomized block design (RCBD) in three replications in Razi University in Iran from 20...

The effect of leachates of different phenological stages of Cassia occidentalis L. on Parthenium hysterophorus L. was studied. Seed germination, radicle length, plumule length and fresh and dry weight of Parthenium were recorded. Pigments and protein contents were also measured to evaluate relation between biochemical and biophysical parameters of Parthenium under stress. The leaf leachate of C...

in order to study of sodium nitroprusside(snp) application effect on growth indices and water use efficiency of kidney beans cultivars(akhtar and derakhshan) under water deficit stress, an experiment was conducted in split factorial based in randomized complete block design with three replications in bu-ali sina university research field at 2012. water stress treatments included vegetative stre...

The chemical and enzymatic properties of the cytochrome system in the particulate preparations obtained from dormant spores, germinated spores, young vegetative cells, and vegetative cells of Bacillus subtilis PCI219 were investigated. Difference spectra of particulate fractions from dormant spores of this strain suggested the presence of cytochromes a, a(3), b, c(+c(1)), and o. All of the cyto...

Translationally controlled tumor protein (TCTP) is a highly conserved and ubiquitously expressed protein present in all eukaryotes. Cellular functions of TCTP include growth promoting, allergic response and responses to various cellular stresses, but the functions in filamentous fungi have not been reported. In this report, we characterized an Aspergillus nidulans TCTP (TcpA) with high similari...

Two Þeld experiments were conducted in 1995Ð1996 to determine if there are common photosynthetic and vegetative growth responses among genotypes of maize, Zea mays L., to larval western corn rootworm, Diabrotica virgifera virgifera LeConte injury. SpeciÞc variables measured from rootworm infested and noninfested plants were midday leaf photosynthetic rate, plant growth stage, and plant height d...

Bacillus subtilis strains lacking penicillin-binding protein 1 (PBP1), encoded by ponA, required greater amounts of Mg2+ or Ca2+ for vegetative growth or spore outgrowth than the wild-type strain and strains lacking other high-molecular-weight (HMW) PBPs. Growth of ponA cells in a medium low in Mg2+ also resulted in greatly increased cell bending compared to wild-type cells or cells lacking oth...
