Sucrose (Suc):Suc 1-fructosyltransferase (1-SST) is the key enzyme in plant fructan biosynthesis, since it catalyzes de novo fructan synthesis from Suc. We have cloned 1-SST from onion (Allium cepa) by screening a cDNA library using acid invertase from tulip (Tulipa gesneriana) as a probe. Expression assays in tobacco (Nicotiana plumbaginifolia) protoplasts showed the formation of 1-kestose fro...

The molecular structure of the exceptional telomeres of six plant species belonging to the order Asparagales and two species of the order Liliales was analyzed using Southern blot and fluorescence in situ hybridization. Three different situations were found, namely: i) In the two Liliales species, Tulipa australis (Liliaceae) and Merendera montana (Colchicaceae), the chromosome ends display hyb...

Our research was carried out in the ridges of Western Tien Shan (Uzbekistan). The study analyzed age structure 9 local populations (LP) Tulipa greigii Regel. ontogenetic T. is represented by two types spectrum – left-sided (LP 1, 2, 4, 5, 6, 8, 9) and centered 3, 7). studied are normal, incomplete. It noted that young mature. scientific justification ways ecological improvement coenopopulation....

Next Generation Sequencing (NGS) may enable estimating relationships among genotypes using allelic variation of multiple nuclear genes simultaneously. We explored the potential and caveats of this strategy in four genetically distant Lilium cultivars to estimate their genetic divergence from transcriptome sequences using three approaches: POFAD (Phylogeny of Organisms from Allelic Data, uses al...

Ring chromosomes, long of interest in cytogenetics, have been intensively studied in corn and Drosophila (McClintock, 1932, 1938; Morgan, 1933; Battacharya, 1950) and also described in Crepis, Tulipa, Tradescantia, and other species. In the past few years, a number of reports of ring chromosomes in man have appeared (Table I). We recently encountered a mentally retarded patient with multiple co...
