Plants of the genus Taraxacum Wigg., have long been used as medicinal herbs. A phytochemical investigation of the aerial parts of Taraxacum bessarabicum (Hornem.) Hand.-Mazz. subsp. bessarabicum (Hornem.) Hand.-Mazz. (Asteraceae) yielded two coumarins [esculetin (1), cichoriin (2)], three flavonoids [ luteolin (3), luteolin 7-O-β-D-glucoside (4), gossypetin (5)] and six phenolic acids and their...

Abstract Utilization of modern breeding techniques for developing high yielding and uniform plant types ultimately narrowing the genetic makeup most crops. Narrowed these crops has made them vulnerable towards disease insect epidemics. For sustainable crop production, variability must be broadened against various biotic abiotic stresses. One ways to widen configuration is identify novel additio...
Speciation and allopolyploidization in cereals may be accompanied by dramatic changes in abundance of centromeric repeated transposable elements. Here we demonstrate that the reverse transcriptase part of Ty3/gypsy centromeric retrotransposon (RT-CR) is highly conservative in the segmental hexaploid Thinopyrum intermedium (JrJvsSt) and its possible diploid progenitors Th. bessarabicum (Jb), Pse...
Durum wheat (Triticum turgidum L., 2n = 4x = 28; AABB genomes) is a natural hybrid-an allotetraploid between 2 wild species, Triticum urartu Tumanian (AA genome) and Aegilops speltoides Tausch (BB genome). Even at the allotetraploid level, durum wheat can tolerate chromosomal imbalance, for example, addition of alien chromosome 1E of diploid wheatgrass, Lophopyrum elongatum. Therefore, one way ...
synthetic plants as well as wild crop species are valuable genetic resourses. to determine the genetic variation in triticale, tritipyrum as well as wheat lines, genomic dna of this amphiploid including thinopyrum bessarabicum and durum wheat were amplified using 32 random and 22 semi random primers. primers that could produce clear, polymorphic and repetitive bands are used for determination o...
