SFL1 and SFl2 (SETH Four Like) genes are two members of SETH4 gene family in Arabidopsis thaliana expressed in saprophytic tissues. In this study, expression of SFL1 and SFL2 genes were studied using Gateway Cloning Technology. Primers were designed for PCR amplification of promoter region of SFL1 (900 bp) and SFL2 (930 bp) genes having attB1 recombination sites using Kod Hi Fi DNA polymerase e...

artemisia annua is an annual herb native to asia most probably china produce one of the most important sesquiterpene namely artemisinin which has antimalarial and anticancer activity. three transcription factors belonging to wrky family, two transcription factors belonging to myb family and two enzymes dbr2 and opr3 were isolated from a.  annua leaves and first inserted into pjet1.2 vector then...

camv 35s promoter activity has not been analysed in different stages of growth in oil-seed (b. napus). higher plants lack intrinsic β-glucuronidase activity, thus enhancing the sensitivity with which measurements can be made. the binary transformation vector pvw432 (buchanan-wollaston, unpublished), carrying the gus gene fused to the camv 35s promoter, was used to test transformation efficienci...

sfl1 and sfl2 (seth four like) genes are two members of seth4 gene family in arabidopsis thaliana expressed in saprophytic tissues. in this study, expression of sfl1 and sfl2 genes were studied using gateway cloning technology. primers were designed for pcr amplification of promoter region of sfl1 (900 bp) and sfl2 (930 bp) genes having attb1 recombination sites using kod hi fi dna polymerase e...

current investigations indicate different in vitro infection patterns for oka and dumas strains. infection of cells in culture with dumas strain produces lower number of infectious particles while the oka strain is highly infectious in vitro. it is postulated that weak expression of the replication genes in dumas strain may be the reason for the attenuated phenotype. the objective of this stud...

introduction: follicle stimulating hormone (fsh) is one of the pituitary glycoproteines that it consists of two subunits alpha and beta. the beta subunit is responsible for the biological activity of fsh. the aim of present study was isolation of the β subunit coding sequence containing its signal sequence from human genome and then cloning of the isolated sequence in ppic9 shuttle vector under...

BENCHMARKS Understanding gene regulation is of fundamental importance to virtually all biological systems. A gene is regulated through cis-acting regulatory DNA sequences (elements) in conjunction with transacting regulatory proteins. The cis-acting regulatory elements involved in transcription include, for example, the promoter, enhancer, silencer, specific activator binding sites, and specifi...
