Aegilops species have significantly contributed to wheat breeding despite the difficulties involved in handling of wild species, such as crossability and incompatibility. A number biotic resistance genes been identified incorporated into varieties from this genus is also contributing toward improvement complex traits yield abiotic tolerance for drought heat. The D genome diploid tauschii has utilized most often programs. Other are more difficult utilize because lower meiotic recombination...
In recent years, wheat yield per hectare appears to have reached a plateau, leading concerns for future food security with an increasing world population. Since its invention, synthetic hexaploid (SHW) has been shown be effective genetic resource transferring agronomically important genes from wild relatives common wheat. It provides new sources potential, drought tolerance, disease resistance, and nutrient-use efficiency when bred conventionally modern varieties. SHW is becoming more...
Abstract Synthetic hexaploid (SH) wheat (AABBD’D’) is developed by artificially generating a fertile hybrid between tetraploid durum ( Triticum turgidum , AABB) and diploid wild goat grass Aegilops tauschii D’D’). Over three decades, the International Maize Wheat Improvement Center (CIMMYT) has utilized SH to bridge gene transfer from Ae . bread wheat. This unique example of success utilizing relatives in mainstream breeding at large scale worldwide. Our study aimed determine genetic...
Significance Globally, wheat farming is a major source of nitrogen pollution. Rapid generation soil nitrates cause leakage and damage ecosystems human health. Here, we show the 3Ns b S chromosome arm in wild grass (Leymus racemosus) that controls root nitrification inhibitor production can be transferred into elite cultivars, without disrupting agronomic features. Biological inhibition (BNI)–enabled wheats improve ammonium levels by slowing down its oxidation generate significant synergistic...
To date, the International Maize and Wheat Improvement Center (CIMMYT) has produced more than 1000 synthetic hexaploid wheats (SHWs), using diverse accessions of D genome donor species (Aegilops tauschii). Many these SHWs from many different Ae. tauschii have shown resistance or tolerance to various biotic abiotic stresses, indicating potential importance gene pool for breeding purposes. were backcrossed CIMMYT improved germplasm produce backcross-derived lines (SBLs), which are...
Abstract Severe lodging has occurred in many improved rice varieties after the recent strong typhoons East and Southeast Asian countries. The indica variety Takanari possesses culm characteristics due to its large section modulus, which indicates thickness, whereas japonica Koshihikari is subject substantial bending stress thick cortical fibre tissue. To detect quantitative trait loci (QTLs) for resistance eliminate effects of genetic background, we used reciprocal chromosome segment...
Abstract Development of winter wheat ( Triticum aestivum ) synthetics started at CIMMYT-Mexico in 2004, when durum turgidum germplasm from Ukraine and Romania was crossed with Aegilops tauschii accessions the Caspian Sea region. Chromosomes were doubled after pollination embryo rescue, but chromosome number cytological validation not performed. F 2 populations grown Mexico shipped to Turkey 2008. During 2009–2015, these subjected rigorous pedigree selection under dry, cold, disease-affected...
Wheat blast is a devastating disease in the tropical and subtropical regions of South America has recently spread to Bangladesh Zambia. Host resistance this primarily relied on 2NS/2AS translocation, making it crucial identify utilize novel sources resistance. In current study, recombinant inbred line population consisting 345 BC 1 F 4 progenies was generated, using susceptible wheat genotype 'Gladius' as female recurrent parent, resistant Aegilops tauschii 'KU-2097' male parent. Field...
Synthetic nitrification inhibitors (SNI) and biological (BNI) are promising tools to limit nitrogen (N) pollution derived from agriculture. Modern wheat cultivars lack sufficient capacity exude BNIs, but, fortunately, the chromosome region (Lr#n-SA) controlling BNI production in
We conducted genomic in situ hybridization (GISH) analyses to clarify constitutions of Thinopyrum intermedium (Host) Barkworth & D. R. The results revealed that Th. contains three kinds genomes: St, E/J, and the third genome distinct from previous two genomes which may be close V genome.However, PCR analysis denied presence present-day but showed some similarity R genome.Thus, formula can tentatively re-designated as StStJ s J (V-J-R) .We also demonstrated probe would useful characterize...
Psathyrostachys huashanica Keng (2n = 14; NhNh) is an endangered wheat-related species, with a distribution in the Huashan region of central China. It has many agronomically promising characters including resistance to disease and drought winter hardiness. We produced hybrids between common wheat as female parent P. male parent. From offspring, we selected chromosome addition lines carrying each all seven chromosomes huashanica. Four (B, D, E F) were recovered disomic three (A, C G)...
Synthetic hexaploid wheat (SHW) has shown effective resistance to a diversity of diseases and insects, including tan spot, which is caused by Pyrenophora tritici-repentis, being an important foliar disease that can attack all types several grasses. In this study, 443 SHW plants were evaluated for their spot under controlled environmental conditions. Additionally, genome-wide association study was conducted genotyping entries with the DArTSeq technology identify marker-trait associations...
Two novel repetitive DNA sequences, pCtKpnI-1 and pCtKpnI-2, were isolated from Carthamus tinctorius (2n = 2x 24) cloned. Both represent tandemly repeated sequences. The pCtKpnI-2 clones constitute repeat units of 343–345 bp 367 bp, respectively, with 63% sequence heterogeneity between the two. Fluorescence in situ hybridization (FISH) was employed on metaphase chromosomes C. using, simultaneously, found to be exclusively localized at subtelomeric regions most chromosomes. On other hand,...
Hordeum vulgare, cultivated barley, and its wild relative, H. chilense, have several important traits that might be useful for wheat improvement. Here, in situ hybridization barley expressed sequence tag (EST) markers were used to characterize compare the chromosomes of chilense with those vulgare. FISH four repetitive DNA sequences, AG, AAG, 5S rDNA 45S rDNA, was applied mitotic available wheat-H. addition substitution lines. AAG repeat differentiated individual The patterns signals two...
The main objective of this study is to produce DNA markers polymorphism between wheat and some important alien species. applicability 1,165 barley EST primer sets amplify showing ten species, covering a wide range variation in Triticeae, was investigated. These primers consisted four series. Series 1 randomly chosen from pool sets. remaining three were pre-screened previous showed polymorphic co-amplified patterns wheat. From 22% 100% the amplified single clear bands species; 29% 75% which...
