Restriction map variation in two 5-6-kb chloroplast DNA regions of five diploid Aegilops species in the section Sitopsis and two wild tetraploid wheats, Triticum dicoccoides and Triticum araraticum, was investigated with a battery of four-cutter restriction enzymes. A single accession each of Triticum durum, Triticum timopheevi and Triticum aestivum was included as a reference. More than 250 re...
A mitochondrial (mt) transcriptional unit, nad3-orf156, was studied in the nucleus-cytoplasm hybrids of wheat with D/D2 plasmons from Aegilops species and their parental lines. A comparative RFLP analysis and sequencing of the random PCR clones revealed the presence of seven sequence types and their polymorphic sites were mapped. All the hybrids possessed the paternal copies besides the materna...
در این تحقیق تعداد 120 نمونه Aegilops crassa (با ژنوم MMDD) بومی ایران از نظر پروتئینهای گلوتنین با وزن مولکولی بالا مورد بررسی قرار گرفتند. پس از ارزیابی نوارهای باندی از بین متنوعترین نوارها، 17 الگوی باندی انتخاب و جهت تعیین نوع پروتئین آنها از روش اسپکترومتری جرمی استفاده گردید. از بین 17 باند تنها 6 باند با احتمال بالا شناسایی گردیدند. از باندهای شناسایی شده 2 باند با باندهای موجود در Ae...
We have used network analysis to study gene sequences of the Triticum and Aegilops 5S rDNA arrays, as well as the spacers of the 5S-DNA-A1 and 5S-DNA-2 loci. Network analysis describes relationships between 5S rDNA sequences in a more realistic fashion than conventional tree building because it makes fewer assumptions about the direction of evolution, the extent of sexual isolation, and the pat...
We agree with Sandve et al. (2015) that the nomenclature of Aegilops /Triticum lineages is complex. Indeed, there is a contradiction in how they themselves have defined ‘theDgenome lineage’ in their Letter (Sandve et al., 2015), compared to their earlier paper (Marcussen et al., 2014). Fig. 1 of Sandve et al. (2015) defines it as a clade comprising D + S* + M genome species; this definition is ...
