AMMI Analysis of Wheat Substitution Lines for Detecting Genes Controlling Adaptability
To locate the genes controlling adaptability in bread wheat using AMMI (additive main effect and multiplicative interaction) model, twenty-one substitution lines derived from the parents Chinese Spring (recipient) and Chayan (donor) were used in a randomized complete block design with three replications in three different environments in the Agricultural College of Razi University, Kermanshah, ...
متن کاملFrequency of Human Platelet Antigens (HPA-2/3/5) Polymorphism in Iranians Evaluated by RFLP-PCR
ackground: Knowing the human platelet antigens (HPA) and genes frequency in different populations is important not only for population studies but also for clinical transfusion practice. HPA genes frequency in Iran is not evaluated, so we investigated the HPA-2, HPA-3, and HPA-5 frequency and their polymorphism. Materials and Methods: DNA from 120 Iranians (99 Iranian blood donors and 21 patie...

متن کاملFluorinated vitamin D analogs to probe the conformation of vitamin D in its receptor complex: 19F-NMR studies and biological activity.
To investigate vitamin D conformation, specifically the A-ring and seco-B ring parts, in its complex with the vitamin D receptor (VDR), we have previously suggested the use of 19F-NMR spectroscopy and have synthesized three fluorovitamin D derivatives to be used for the study, 4,4-difluoro-1alpha,25-dihydroxyvitamin D3 [4,4-F2-1,25-(OH)2D3, 2a], and (10Z)- and (10E)-19-fluoro-1alpha,25-dihydrox...
