| [molecular markers linked to dwarf gene rht3 in wheat]. | the dwarf gene rht3 derived from tom thumb variety, a tibetan wheat of china, is a dominant gene with the insensitivity to gibberellic acid. rht3 shows to depress alpha-amylase activity and hence enchance the resistance to preharvest sprouting mainly through its effect on the expression of alpha-amy1. near isogenic lines with rht3 and their segregating population were analyzed by pcr and rflp techonology. in rapd analysis, out of 310 random primers (10 bp) screened, only three primers of ubc389, ... | 2001 | 11725637 |
| assessment of genetic diversity of yunnan, tibetan, and xinjiang wheat using ssr markers. | a total of 206 ssr (simple sequence repeats) primer pairs were used to detect genetic diversity in 52 accessions of three unique wheat varieties of western china. a total of 488, 472, and 308 allelic variants were detected in 31 yunnan, 15 tibetan and 6 xinjiang wheat accessions with an average of pic values 0.2764, 0.3082, and 0.1944, respectively. substantial differences in allelic polymorphisms were detected by ssr markers in all the 21 chromosomes, the 7 homoeologous groups, and the three ge ... | 2007 | 17643948 |
| identification of quantitative trait loci for seedling root traits from tibetan semi-wild wheat (triticum aestivum subsp. tibetanum). | as a primitive hexaploid wheat resource distributed only in tibet, tibetan semi-wild wheat (triticum aestivum subsp. tibetanum shao) possesses unique characteristics that could be exploited in wheat breeding programs. its good root system could offer a stable platform for above-ground components. to detect possible excellent locus for root traits from tibetan semi-wild wheat, we identified qtls for root traits using a recombinant inbred line population derived from a cross between tibetan semi-w ... | 2017 | 28841403 |
