this experiment was carried out to evaluate the effect of rhizobium strains and plant growth promoting rhizobacteria (pgpr) on dry matter partitioning and some growth parameters of chickpea (cicer arietinum l.) arman cultivar. this research was conducted as split plot based on complete random block design at zanjan university research farm. irrigation levels (optimum irrigation during season gr...
Development of vegetative and floral buds was found to be a key factor in establishing the way carbon is distributed among growing leaves and fruits in Phaseolus vulgaris L. plants. Leaves emerged principally during a period 14 to 32 days after planting while flowers were produced during a 10- to 12-day period near the end of leaf emergence. Timing of anthesis established the sigmoidal time cou...
The aim of this work was to investigate the occurrence of phosphoenolpyruvate carboxykinase (PEPCK) in different tissues of Arabidopsis thaliana throughout its vegetative and reproductive growth. The A. thaliana genome contains two PEPCK genes (PCK1 and PCK2), and these are predicted to generate 73,404 and 72,891 Da protein products, respectively. Both genes were transcribed in a range of tissu...
The study was conducted to determine the specific chemical constituents of cattle urine and indigenous plant extracts. Chemical analysis revealed that the specific chemical composition i.e., chloride, sulphate, nitrite and phosphorus pentaoxide contents of fresh and fermented cattle urine were 1556, 364, 2.0, 26.8 and 4514, 252, 22.4, 7.49 mg l-1, respectively. The proximate chemical compositio...
PURPOSE To determine the minimum inhibitory concentration (MIC) and minimum fungicidal concentration (MFC) for the extracts of the leaves and seeds of the plant Azadirachta indica against various dermatophytes. METHODS Clinical isolates of dermatophytes(Trichophyton rubrum, Trichophyton mentagrophytes and Microsporum nanum) were treated with extracts of leaves and seeds of the plant Azadirach...
The stems and leaves of the Dolichos biflorus plant contain a lectin that cross-reacts with antiserum against the seed lectin. This cross-reactive material (CRM) was followed during early seedling growth, stem elongation, and seed development using a specific radioimmunoassay.No CRM was detected in developing seeds, but very low levels were found in dormant and imbibed seeds. As germination pro...
We isolated two transcription factor genes, heterotrimeric G protein beta 2 subunit (Gβ2) and ArcA1, from pepper (Capsicum annuum). The complete coding sequences were amplified using reversed transcriptase PCR based on conserved sequence information of Solanum lycopersicum and several other plant species. Nucleotide sequence analysis of these two genes revealed that the pepper Gβ2 gene encodes ...
Nystroemiaceae is proposed as a new family of gymnosperms from the Permian of Cathaysia that adds to the diversity of gymnosperms known from this critical time in seed plant evolution. This family is characterized by bifurcating and highly branched pinnate ovuliferous organs bearing bicornute ovules (seeds) and entire leaves with anastomozing veins that are born on complex and modern-looking br...
BACKGROUND Zizyphus lotus L. (Desf.) also known as Jujube, is a deciduous shrub which belongs to Rhamnaceae family. This plant is used in Algerian traditional medicine for its anti-diabetic, sedative, analgesic, anti-inflammatory and hypoglycaemic activities. In the present study, we determined the concentrations of different vitamins (vitamin A, C and E) and fatty acids in root, stem, leaves, ...
A general method has been developed for determination of the total cyanide content of all cyanogenic plants and foods. Ten cyanogenic substrates (cassava, flax seed, sorghum and giant taro leaves, stones of peach, plum, nectarine and apricot, apple seeds and bamboo shoot) were chosen, as well as various model compounds, and the total cyanide contents determined by the acid hydrolysis and picrat...
