Each step of the seed-to-seed cycle of plant development including seed germination is characterized by a specific set of proteins. The continual renewal and/or replacement of these biomolecules are crucial for optimal plant adaptation. As proteins are the main effectors inside the cells, their levels need to be tightly regulated. This is partially achieved by specific proteolytic pathways via ...

in order to study the effects of integrated application of bio-fertilizer and chemical fertilizers on yield and yield components of corn, an experiment was conducted in 2008 in dezful city, (khoozestan province) in a factorial arrangement based on complete randomized block design with four replications. treatments were integrated application of biological and chemical fertilizers in four levels...

In the course of studies on biologically active substances from pathogenic microorganisms, a new antibiotic SO-75R1 was isolated from the mycelium of Nocardia brasiliensis IFM 075. This paper describes the fermentation, isolation and structural elucidation of SO-75R1. The seed broth was prepared by inoculating mycelial elements of the producing strain (IFM 075) grown on Sabouraud dextrose agar ...

Man has always been fascinated by miscellaneous elements in nature. Amongst them all, the most astonishing is the principle of world i.e. ‘ seed’ and ‘womb’, and the vital role played for their existence is by ‘prana’ or breath. This theory led to the evolution of the cult of fertility. In almost all religious practices fertility is represented with symbols, rituals and prayers. In plain langua...

I n plants, DNA methylation plays important roles in silencing transposable elements (TEs) and endogenous genes. Several elegant examples of dynamic changes in DNA methylation during gamete or seed development have been recently described in Arabidopsis (1, 2). A considerable number of cell-to-cell variations in methylation have also been detected in vegetative tissues (3, 4); however, whether ...

The content of metal elements in plant tissues of 10-day wheat seedlings after seed pre-treatment and foliar treatment with non-ionic colloidal solution of metal nanoparticles (Fe, Mn, Cu, Zn) was determined by an atomic absorption spectrometer. It was shown that metal nanoparticles due to their physical properties (nanoscale and uncharged state) were capable of penetrating rapidly into plant c...

abstract- to investigate the effects of bio-chemical and organic fertilizers on yield and seeds npk contents of pumpkin (cucurbita pepo var. styriaca), an experiment was conducted at the research farm of kurdistan university in 2009 growing season. treatments were included 1) control, 2) seeds inoculated with free-living n fixing bacteria (nfb), 3) seeds inoculated with phosphate-solubilizing b...

The type II supernova is considered as a candidate site for the production of heavy elements. Since the supernova produces an intense neutrino flux, neutrino scattering processes will impact element formation. We examine active-sterile neutrino conversion in this environment and find that it may help to produce the requisite neutron-to-seed ratio for synthesis of the r-process elements. The r-p...

Levels of sodium, potassium, calcium and magnesium were determined in plant organs (bud, flowers, fruit, seed, leaves, stems, roots, cobs, styles, shaft, grains and efflorescences) of three Fadama farms located in Ifaki-Ekiti, Ado-Ekiti and Ikere-Ekiti of Ekiti State, Nigeria. The highest levels of Mg, K, Na and Ca were obtained in the bud of Hibiscus esculentus with respective values (ppm dry ...
