Abstract
شناسايي ژن هايي با سطح بيان ثابت يكي از پيش نيازهاي ارزيابي تغييرات ترانسكرپيتوم است. بيان اين ژن ها بطور ايدهآل

Abstract
Identification of genes with invariant levels of gene expression is a prerequisite for validating transcriptomic
changes accompanying development. Ideally expression of these genes should be independent of the
morphogenetic process or environmental condition.We report here the validation of internal control gene
i.e.TPS (trehalose 6-phosphate-synthase) in cotton (Gossypium spp), using TaqMan system in quantitative
Real Time PCR (qRT-PCR). The Gene expression was tested in five different G. hirsutum cultivars including
Coker 312, Acala SJ, ZETA 2, Taghva, Neishabour and a diploid wild type; G. barbadense. Identical
amplicons were obtained within these cultivars. No amplifications was achieved when DNA samples from
barley (Hordeum vulgare), maize (Zea mays), rice (Oryza sativa), Fig (Ficus carica), pistachio (Pistacia
vera), yew (Taxus baccata), wheat (Tirticum aestivum), rose (Rosa hybrida) and soybean (Glycine max) were
used as template. Therefore, it was confirmed that the primers and probes designed in this study were specific
for the identification and quantification of internal control gene. These results reveal the possibility of using
the TPS gene as an internal control in cotton. In another word, this gene would be a suitable candidate as a
reference gene in examination of gene expression, detection of transgenic cotton and determining e the
zygosity as well as the copy number of the transgene.
