روشهای مولکولی جهت ارزیابی معیارهای تاکسونومیکی ورتیسیلیومهای مرتبط با گیاهان مورد استفاده قرار گرفتند. سی و یک استرین ورتیسیلیوم به وسیله مقایسه its-rflps به چهار کلاستر تقسیم شدند. کلاستر اول در بر گیرنده استرینهای گونه تیپ v. luteo-album (link : fries) subramanian؛ کلاستر دوم شامل v. albo-atrum reinke & berthold، v. dahliae klebahn، v. nubilum pethybridge،v. tricorpus isaac؛ کلاستر س...
background: hla-g gene contains 15 alleles including a null allele, hla-g*0105n. previous studies have shown that hla-g*0105n does not encode the complete hla-g1 or hla-g5 isoforms but encodes a functional hla-g protein with the ability to in-hibit nk cell cytolysis. thus, although the biological functions of hla-g1 and hla-g5 proteins are abrogated, other isoforms such as hla-g2 can replace th...
Recombinant DNA clones carrying high-copy or low-copy sequences from Aspergillus nidulans and Neurospora crassa were used to identify restriction fragment length polymorphisms (RFLPs) diagnostic for members of the A. flavus group: A. flavus, A. parasiticus, and A. nomius. These fungi were resolved into three distinct categories when they were grouped according to RFLP patterns. Subgroups within...
The recent discovery that the gene causing Huntington's disease (HD) resides on chromosome 4 has generated increased interest in this autosome. Chromosome 4 contains two of the more informative conventional genetic markers, GC and MNS, but most loci have been assigned to it by recombinant DNA techniques. There are currently more anonymous DNA fragments detecting restriction fragment length poly...
48,XXXX and 49,XXXXY chromosome constitutions are rare and while several such polysomies have been described in the past, the parental origin of the supernumerary chromosomes has only been described in a few cases.'2 More recently, difficulties owing to the reduced informativeness of the Xg antigen marker have been overcome by the use of X linked restriction fragment length polymorphisms (RFLPs...
background: human leukocyte antigen-g (hla-g) is a non-classical class i molecule highly expressed by extravillous cytotrophoblast cells. due to a single base pair deletion, its function can be compensated by other isoforms. investigating the frequency of null allele in recurrent miscarriage (rm) subjects could be useful in understanding the relationship between frequency of this allele and rm ...
