ژنهای rooting locus) rol) بر روی Transferred DNA) T-DNA) باکتری Agrobacterium rhizogenes قرار دارند که با انتقال به میزبان گیاهی باعث ایجاد تغییرات مورفولوژیک و رشد و نموی در گیاه می شوند. این تحقیق با هدف بررسی تاثیر ژن rolC از این باکتری و هومولوگ گیاهی آن یعنی ژن trolC از گیاه توتون، بر رشد و نمو گیاه Nicotiana tabacum cv.samsun انجام گرفته است. در این تحقیق ابتدا DNA گیاهان تراژن rolC و tr...
BACKGROUND Homology-dependent selective degradation of RNA, or post-transcriptional gene silencing (PTGS), is involved in several biological phenomena, including adaptative defense mechanisms against plant viruses. Small interfering RNAs mediate the selective degradation of target RNA by guiding a multicomponent RNAse. Expression of self-complementary hairpin RNAs within two complementary regio...
The application of strain into GeSn alloys can effectively modulate the band structures, thus creating novel electronic and photonic devices. Raman spectroscopy is a powerful tool for characterizing strain; however, lack coefficient makes it difficult accurate determination in alloys. Here, we have investigated Raman-strain function Ge1-xSnxalong ?1 0 0? 1 directions. nanomembranes (NMs) with d...
OBJECTIVE To assess the prevalence of synchronous roentgenographically occult lung carcinoma (ROLC) in patients with resectable roentgenographically visible lung cancer (RVLC). METHODS Patients undergoing surgery for RVLC in the same University Hospital were prospectively evaluated before surgery by fluorescence bronchoscopy under local anesthesia to detect synchronous ROLC. All abnormal area...
Potato plants harboring Phytochrome B (PHYB) gene from Arabidopsis thaliana or rol genes from Agrobacterium rhizogenes were used to study the effect of transgene expression on structure and properties of starch in tubers. Thermodynamic characteristics of starch (melting temperature, enthalpy of melting, thickness of crystalline lamellae) were shown to be variable depending on the transgene expr...
