Since seed reserves can influence seed germination, the quantitative and qualitative differences in seed reserves may relate to the germination characteristics of species. The purpose of our study was to evaluate the correlation between germination and seed reserves, as well as their mobilization during germination of six grassland species (Chloris virgata, Kochia scoparia, Lespedeza hedysaroid...

agronomic and physiological traits and protein expression were compared between non-bt glandless upland cotton variety-zhong5629 and its bt-transgenic near-isogenic lines differing in cryiac gene. results showed that the bt isogenic line had higher plant height and rate of effective bolls, more internal bolls but lower yield, than the non-bt line. the bt isogenic line had lower chlorophyll cont...

Background and Aims: Q59L mutant of L-asparaginase enzyme from Escherichia coli (E. coli) has been introduced with lower side effects. This version of the enzyme might have potential applications in the treatment of leukemia patients. We utilized SHuffle T7 strain of E. coli, to produce the mutant enzyme in the presence of chaperone molecules. Materials and Methods: Q59LAsp gene was cloned in...

Objective Paracrine disruption of growth factors in women with polycystic ovarian syndrome results in production of low quality oocyte, especially following ovulation induction. The aim of this study was to investigate the effects of metformin (MET), N-acetylcysteine (NAC) and their combination on the hormonal levels and expression profile of GDF-9, BMP-15 and c-Kit, as hallmarks of oocyte qual...

three experiments were conducted in tissue culture and biotechnology laboratory of horticulture department of mohaghegh ardabili university in 2012. for the regeneration of plant from seed, different concentrations of naoh (5, 10, 15, 20 m) and various scarification methods with sandpaper (soft scarification, medium scarification and hard scarification) were used based on completely randomized ...

in order to study the effects of foliar application of zn and k on yield and some physiological traits of spring safflower (carthamus tinctorius l.), cv. esfahan 14, under drought stress, a pot experiment was conducted in research greenhouse of yasouj university. experiment was a factorial based on completely randomized design with three replications. factors consisted of drought stress (s1- wi...

A colchicine-binding assay and quantitative sodium dodecyl sulfate gel electrophoresis have been used to determine the changes which occur in microtubule protein (tubulin) concentrations in the particulate and soluble fractions of mouse oviduct homogenates during that period of development when centriole formation and cilium formation are at a maximum. When mouse oviducts, at various ages after...
