The fungus Blumeria graminis f. sp. tritici causes wheat powdery mildew disease. Here, we study its spread and evolution by analyzing a global sample of 172 genomes. Our analyses show that B.g. emerged in the Fertile Crescent during domestication. After it throughout Eurasia, colonization brought to America, where hybridized with unknown grass species. Recent trade USA strains Japan, European China. In both places, they local ancestral strains. Thus, although spreads wind regionally, our...
AbstractAbstractA low cadmium (Cd) concentration in wheat grain is desirable because of Cd toxicity to humans. Grain concentrations Japanese differed among the varieties previous study. In this study, we hypothesized that with a have (1) uptake from soil through roots during early growth and/or (2) translocation shoots, and also, (3) affected by root morphology. These hypotheses were verified investigating quantity root, shoot leaf tissues, examining morphology young seedlings high...
Abstract Fusarium head blight ( FHB ) remains a serious problem due to yield loss and mycotoxin accumulation in wheat production worldwide. We previously reported that the closed‐flowering (no anther extrusion) characteristic was effective for increasing resistance infection. In this study, we investigated relationships between degree of extrusion AE damage using double haploid lines DHL s), derived from F 1 plants crosses opened‐flowering varieties. These s exhibited various degrees ,...
RNA-targeted small molecule drug discovery is widely recognized as an important modality. However, not enough knowledge on the interaction between RNAs and molecules accumulated yet. In present study, 46 were designed with various internal loops or hairpin based a 29-mer model RNA. The of three kind molecules, risdiplam, naphthyridine carbamate dimer (NCD) ciprofloxacin, examined by NMR spectroscopy. results experiments quantitatively analyzed interacting selected. Among compounds, NCD shows...
Wheat blast caused by
In wheat (Triticum aestivum L.), Fusarium head blight (FHB) resistance is an important breeding target to reduce yield losses and mycotoxin contamination. We hypothesized that cleistogamous (CL, closed flowering) cultivars have a lower risk of FHB infection than chasmogamous (CH, opened because usually occurs in the inside florets or extracted anthers CL decreases accumulation. To test these hypotheses, we produced 126 recombinant inbred lines (RILs) derived from cross between common...
A quantitative trait locus (QTL) controlling wheat grain protein content (GPC) and flour (FPC) was identified using doubled haploid (DH) lines developed from a cross between the hard red winter variety 'Yumechikara' with high used for bread making, soft 'Kitahonami' low Japanese white salted noodles. single major QTL, QGpc.2B-yume, on short arm of chromosome 2B both GPC FPC over 3 years testing. QGpc.2B-yume mapped flanking region microsatellite marker Xgpw4382. The DH grouped by haplotype...
Shiratae Nijo is a new two-rowed food barley cultivar bred at the National Agricultural Research Center for Kyushu Okinawa Region (KONARC) in collaboration with Institute of Crop Science (NICS) and released 2009. proanthocyanidin-free by backcross breeding using leading Nishinohoshi as recurrent parent foreign mutant ant28-494 non-recurrent parent. The agronomic characteristics are almost same those which has high yield performance resistance to yellow mosaic virus (BaYMV) type I powdery...
The timing of heading is largely affected by environmental conditions. In wheat, Vrn-1 and Ppd-1 have been identified as the major genes involved in vernalization requirement photoperiod sensitivity, respectively. To compare effects alleles on time under different environments, we genotyped homoeologues measured at Morioka, Tsukuba Chikugo Japan for two growing seasons. A total 128 Japanese six foreign varieties, classified into four populations based 519 genome-wide SNPs, were used...

もち性コムギは世界で初めて日本で育成されたが,その利用は菓子や日本麺等のブレンド用にとどまっている.その理由の一つとして,グルテンの強い硬質もち性コムギ品種が存在しないことが挙げられる.すなわち,国内外のグルテンの力が強いコムギ品種は一般的にGlu-D1d遺伝子をもつが,現在,日本で栽培されているもち性コムギ品種はこの遺伝子をもたないため,グルテンの力が弱い.このため,強力コムギ特性が求められるパン等へ食感改良を目的としてブレンドした場合,小麦粉全体のグルテンの力を弱めることになる.農業・食品産業技術総合研究機構・次世代作物開発研究センター(現作物研究部門)は,DNAマーカー選抜,連続戻し交配,世代促進等の技術を用いてGlu-D1d遺伝子をもつ硬質コムギ品種「ユメシホウ」にもち性を導入し,グルテンの強い硬質もち性コムギ品種「モチハルカ」を,熊本製粉株式会社と共同育成した.「モチハルカ」は「ユメシホウ」と比較して穂長がやや長く,容積重と千粒重がやや小さく,外観品質は同程度かやや劣る.穂発芽性は"やや難~難",コムギ縞萎縮病抵抗性は"やや弱",赤かび病は"やや弱"で1ランク劣る.それ...
ムギ類の育種で行われる形質評価・選抜は多くの時間と労力を要するため,これらの高速化・自動化は非常に大きな役割をもつ.深層学習などの登場により飛躍的に発展した画像センシング技術は,画像から様々な情報を高速かつ高精度に取得することを可能にし,育種の効率化に貢献する.そこで,本研究ではこうした画像センシング技術を利用した育種の効率化を目的とし,その一例として物体検出技術を活用したムギ類の穂の検出と穂数調査方法の開発を試みた.穂の検出には,コムギ・オオムギを合わせて2,023枚の訓練画像と674枚の検証画像を供試し,YOLOv4を利用したモデルを作成した.作成した検出モデルは未学習のデータに対するmAP(mean Average...
Wheat yellow mosaic disease is a soilborne caused by wheat virus (WYMV). Symptoms include coloring of leaves, stunting, and growth inhibition. Here we conducted detailed analysis resistance to this in winter 'Hokkai 240' carrying out inoculation tests WYMV conducting field tests. The level observed was compared with those varieties harboring known genes. In the tests, showed Pathotypes I II partial Pathotype III. This result contrary sensitive responses three pathotypes exhibited variety...
Abstract Wheat blast caused by Pyricularia oryzae Triticum pathotype (MoT) has been transmitted from South America to Bangladesh and Zambia is now spreading in these countries. To prepare against its further spread Asian countries, we introduced Rmg8 , a gene for resistance wheat blast, into Japanese elite cultivar, Chikugoizumi (ChI), through recurrent backcrosses, established ChI near-isogenic lines, #2-1-10 with the / genotype #4-2-10 rmg8 genotype. A molecular analysis suggested that at...
Abstract Wheat blast, a devastating disease having spread recently from South America to Asia and Africa, is caused by Pyricularia oryzae pathotype Triticum which emerged in 1985. Rmg8 Rmg7 , genes for resistance wheat blast found common tetraploid wheat, respectively, recognize the same avirulence gene, AVR-Rmg8 . Here, we show an evolutionary process gene(s), had obtained ability before differentiation of Aegilops has expanded its target pathogens. Molecular cloning revealed that was one...
九州地域のコムギ品種について登熟期間中の遭雨が小麦粉色相に及ぼす要因解明を試みた．3回の遭雨によって，種子容積重は1％程度低下し，SKCS種子硬度は7ポイント低下した．さらに電子顕微鏡観察により遭雨小麦粒種皮を観察したところ，遭雨処理したコムギ種子の外皮細胞層間の空隙の増大が観察された．この空隙部分の増加が外皮の脆弱化，ひいては製粉性の低下の要因と考えられた．すなわち，脆弱化した外皮部が製粉時に崩壊するため，製粉効率が低下し，さらに小麦粉に混入することにより，小麦粉の色相が悪化すると推察した．
パン用コムギ品種の育成を目的とした雑種集団種子に対して,塩化カルシウム水溶液を用いた比重選を行い,その効果を調査した.その結果,種子硬度,たんぱく質含有率および容積重の向上が確認できた.特に,たんぱく質含有率については,今回供試した材料においては,F3,F4の両世代で選抜の効果が確認でき,その差も百分率で0.5ポイントと大きかった.また,容積重や種子硬度は,選抜する世代によってその効果が異なったが,一定の効果が確認できた.ただし,比重選により粒重低下や小粒化する傾向が観察され,これを回避するため篩などによる粒径選抜を併用する必要があることが分かった.
Abstract Waxy wheat lines carrying null alleles at the loci Wx‐A1 and Wx‐B1 a mutated Wx‐D1 allele ( Wx‐D1f ) generate unique pasting curves on Rapid Visco Analyzer. The initial temperature, peak viscosity, final viscosity are found to not differ markedly between waxy Wx‐D1b , but hot‐paste is more stable in case of . study seeks determine cause for this starch property. Whereas amylopectin chain‐length distribution similar #211 Wx‐A1b Wx‐B1b Wx‐D1a #234 ), contained 7.0% amylose 1.3%...
