in order to investigation of vermicompost effect on growth and yield of marigold in pot medium, an experiment was done by a randomized completely block design in three raplications. treatmnets were included control (30% v/v of soil plus 70% v/v of sand) and three levels of vermicompost (20, 40, 60 % v/v of vermicompost+30% v/v of sand and soil) that applied in three lit. pots. marigold seeds (t...

human growth hormone (hgh) genomic sequence containing 5 exons and 4 introns was cloned in pcdna-3 and the constructed plasmid was subsequently used for transfection ofnlli-3t3 cell line using lipofection technique. expression of hgh in stably transfected cells was assayed using elisa. total rna was extracted from transfected cells and hgh cdna was amplified by rt-pcr using specific primers. th...
