Partial amino acid sequences of two proteins, purified from barley leaves reacting hypersensitively to the powdery mildew fungus, showed a high degree identity PR-1 proteins originally described in tobacco. The subsequently designated HvPR-1a and HvPR-1b, show apparent pI values approximately 10.5 11, respectively M(r) 15,000. Independently, differential screening cDNA library prepared leaves, exhibiting compatible interaction with resulted isolation species representing homologs. With...
Twenty seven accessions of sorghum conserved in the national gene bank Zambia, representing two three agroecological regions country, were investigated using simple sequence repeats (SSR) markers order to determine extent and distribution its genetic diversity. We used 10 microsatellite primer-pairs, which generated 2–9 alleles per locus a total 44 across 27 accessions. The observed heterozygosity (HoP) among ranged from 0 0.19 with an average 0.04 whereas expected (HeP) was 0.07 line fact...
Coffea arabica L. (arabica coffee), the only tetraploid species in genus , represents majority of world’s coffee production and has a significant contribution to Nicaragua’s economy. The present paper was conducted determine genetic diversity Nicaragua for its conservation breeding values. Twenty-six populations that represent eight varieties were investigated using simple sequence repeat (SSR) markers. A total 24 alleles obtained from 12 loci across 260 individual plants. Nei’s gene...
Common bean ( Phaseolus vulgaris L.) is an important export crop in Kyrgyzstan. The aim of this study was to assess the extent genetic diversity, determine population structure, and relate main gene pools grown Twenty-eight common accessions (including five Kyrgyz cultivars, references from Mesoamerica South America) were evaluated with microsatellites. Nine polymorphic microsatellites used estimate diversity heterozygosity. number alleles per microsatellite locus ranged 2 4 there a total 24...
We have developed RFLP and RAPD markers specific for the genomes involved in evolution of Elymus species, i.e., St, Y, H, P, W genomes. Two P genome repetitive DNA sequences, pAgc1 (350 bp) pAgc30 (458 bp), three pAuv3 (221 pAuv7 (200 pAuv13 (207 were isolated from Agropyron cristatum Australopyrum velutinum, respectively. Attempts to find Y sequences not successful. Primary-structure analysis demonstrated that (P genome) share 81% similarity over a 227-bp stretch. The also highly...
The effect of infestation by the birdcherry‐oat aphid ( Rhopalosiphum padi L.), on induction PR‐proteins was investigated in barley Hordeum vulgare using lines susceptible or resistant to R. padi. PR‐1a (unknown function), PR‐5a (acidic thaumatin) and peroxidase (EC 1.11.1.7) were not affected, whereas one chitinase 3.2.1.14) 4 β ‐1,3‐glucanases 3.2.1.39) induced treatment. In breeding line CI 16145, but cultivar Golf, accumulation basic two acidic increased with time from 2 until 11 days...
Abstract Common bean ( P haseolus vulgaris L .) is one of the most important legume crops for human consumption. However, its grain yield can be reduced by up to 90% seedborne disease, anthracnose. Fungicide treatment costly and time‐consuming. The introduction host plant resistance against this disease appears, therefore, crucial enhancing productivity crop in K yrgyzstan. use DNA ‐based markers backcrossing programmes may help speed breeding resistance. In study, we used a combination...
The phylogenetic relationship between four basic genomes designated H, I, Xa, and Xu in the genus Hordeum was studied using a nuclear DNA sequence. sequence, cMWG699, is single copy H. vulgare genome, tightly linked to vrs1 locus which controls two- six-rowed spikes. fragments homologous cMWG699 were amplified from diploid species nucleotide sequences determined. A phylogeny based on both base substitutions an insertion-deletion event showed that H- Xa-genome groups are positioned one...
