چکیده: در گل های شاخه بریده به حداقل رساندن ضایعات پس از برداشت و افزایش عمر ماندگاری با در نظر گرفتن هزینه های بالای تولید امری بسیار مهم و ضروری است به خصوص در مورد گل های شاخه بریده رز که جایگاه خاصی در تجارت گیاهان زینتی دنیا دارند. گل رز از تیره گلسرخیان، با نام علمی rosahybrida می باشد. این تحقیق به منظور بررسی اثرات کاربرد سطوح مختلف نانو ذرات نقره بصورت تیمار مداوم و محلول پاشی در ارق...
Recent advances in fluorescence microscopy, coupled with CRISPR/Cas9 gene editing technology, provide opportunities for understanding gene regulation at the single-cell level. The application of direct imaging shown here provides an in situ side-by-side comparison of CRISPR/Cas9-edited cells and adjacent unedited cells. We apply this methodology to the steroidogenic acute regulatory protein (St...
We report the development of a new technology for simultaneous quantitative detection of multiple targets in a single sample. Scalable transcriptional analysis routine (STAR) represents a novel integration of reverse transcriptase-polymerase chain reaction and capillary electrophoresis that allows detection of dozens of gene transcripts in a multiplexed format using amplicon size as an identifi...
Steroidogenic acute regulatory protein (StAR) delivers cholesterol to the inner mitochondrial membrane, where the cholesterol side-chain cleavage enzyme carries out the first committed step in steroid hormone biosynthesis. StAR expression is restricted to steroidogenic cells and is rapidly induced by treatment with trophic hormones or cAMP. We analyzed the 5'-flanking region of the mouse StAR g...
Cyclic AMP-dependent expression of the steroidogenic acute regulatory (StAR) protein is thought to be the controlling step for steroid production, but the mechanisms through which external signals are translated into increased transcription of the StAR gene are unknown. We demonstrate that cyclic AMP-induced steroid synthesis is dependent upon the phosphorylation and activation of ERKs and that...
let $d$ be an integral domain and $star$ a semistar operation stable and of finite type on it. we define the semistar dimension (inequality) formula and discover their relations with $star$-universally catenarian domains and $star$-stably strong s-domains. as an application, we give new characterizations of $star$-quasi-pr"{u}fer domains and um$t$ domains in terms of dimension ine...
The sea star Asterias rubens reacts specifically to the antigen:HRP (horse-radish peroxydase) and produces an antibody anti-HRP. We previously identified a candidate Ig kappa gene corresponding to this manuscript. We show now the gene referred to as: "sea star Ig kappa gene in its specificity".
Transcriptional regulation of the steroidogenic acute regulatory (StAR) protein gene by cAMP-dependent mechanisms occurs in the absence of a consensus cAMP-response element (CRE; TGACGTCA) and is mediated by several sequence-specific transcription factors. We previously identified three CRE-like sites (within the -151/-1 bp cAMP-responsive region of the mouse StAR gene), of which the CRE2 site ...
The multispecies coalescent model describes the generation of gene trees from a rooted metric species tree and thus provides a framework for the inference of species trees from sampled gene trees. We prove that the STAR method of Liu et al. (2009) and generalizations of it, are statistically consistent methods of topological species tree inference under this model. We discuss the impact of gene...
