Winter wheats require several weeks at low temperature to flower. This process, vernalization, is controlled mainly by the VRN1 gene. Using 6,190 gametes, we found be completely linked MADS-box genes AP1 and AGLG1 in a 0.03-centimorgan interval flanked Cysteine Cytochrome B5 . No additional were between last two 324-kb Triticum monococcum sequence or colinear regions rice sorghum. Wheat similar Arabidopsis meristem identity AGL2 , respectively. transcription was regulated vernalization both...
Plants with a winter growth habit flower earlier when exposed for several weeks to cold temperatures, process called vernalization. We report here the positional cloning of wheat vernalization gene VRN2, dominant repressor flowering that is down-regulated by Loss function whether natural mutations or deletions, resulted in spring lines, which do not require flower. Reduction RNA level VRN2 interference accelerated time transgenic winter-wheat plants more than month.
Winter wheat and barley varieties require an extended exposure to low temperatures accelerate flowering (vernalization), whereas spring do not have this requirement. In study, we show that in these species, the vernalization gene VRN3 is linked completely a similar Arabidopsis FLOWERING LOCUS T (FT). FT induction leaves results transmissible signal promotes flowering. Transcript levels of orthologues, designated as HvFT TaFT, respectively, are significantly higher plants homozygous for...
Spike architecture influences grain yield in wheat. We report the map-based cloning of a gene determining number spikelet nodes per spike common The cloned is named TaCOL-B5 and encodes CONSTANS-like protein that orthologous to COL5 plant species. Constitutive overexpression dominant TaCol-B5 allele but without region encoding B-boxes wheat cultivar increases produces more tillers spikes, thereby enhancing transgenic plants under field conditions. Allelic variation results amino acid...
Abstract Colinearity of a large region from barley (Hordeum vulgare) chromosome 5H and rice (Oryza sativa) 3 has been demonstrated by mapping several common restriction fragment-length polymorphism clones on both regions. One these clones, WG644, was hybridized to bacterial artificial (BAC) libraries select homologous clones. BAC each species with the largest overlapping segment selected fingerprinting blot hybridization three additional The complete 635P2 50-kb 36I5 were completely...
Abstract Vernalization, the requirement of a long exposure to low temperatures accelerate flowering, is an essential adaptation plants cold winters. The vernalization gene VRN-1 plays important role in this process diploid (Triticum monococcum) and polyploid wheat aestivum). We have recently shown that VRN-Am1 was similar Arabidopsis (Arabidopsis thaliana L. Heynh.) APETALA1 meristem identity gene. also showed dominant Vrn-Am1 alleles were result loss-of-function mutations regulatory regions...
Abstract Winter wheat (Triticum spp.) varieties require long exposures to low temperatures flower, a process called vernalization. The VRN2 locus includes two completely linked zinc finger-CCT domain genes (ZCCT1 and ZCCT2) that act as flowering repressors down-regulated during Deletions or mutations in these result the elimination of vernalization requirement diploid monococcum). However, natural allelic variation has not been described so far polyploid (tetraploid Triticum turgidum...
Excessive use of nitrogen fertilizer affects the sustainable development Korla fragrant pear orchard. Semi-decomposed sheep manure is favored because its advantages being pollution-free, containing more microorganisms, and friendly to soil. However, effects combined with on soil nutrient cycling microbial community in orchards are still unclear. This study involved a two-year field experiment investigate fertilization’s 0–20 cm layer 10–12-year-old trees at maturity. The purpose this was...
A precise regulation of flowering time is critical for plant reproductive success, and therefore, a better understanding the natural variation in genes regulating initiation phase required to develop well-adapted varieties. In both monocot dicot species, FLOWERING LOCUS T (FT) central integrator seasonal signals perceived by leaves. The encoded mobile protein (florigen) transmitted apical meristem where it induces flowering. FT homolog barley (Hordeum vulgare L.), designated HvFT1, was shown...
Summary Winter wheat requires a period of low temperatures to accelerate flowering (vernalization). This requirement could make winter more vulnerable elevated global temperature via insufficient vernalization. All known vernalization genes are cloned according qualitative variation in between spring and wheat, but the controlling quantitative for or less among cultivars remain unknown. We report here that gene duration was using BC 1 F 2:3 population segregated 3:1 ratio early‐flowering...
Vernalization genes determine winter/spring growth habit in temperate cereals and play important roles plant development environmental adaptation. In wheat (Triticum L. sp.), it was previously shown that allelic variation the vernalization gene VRN1 due to deletions or insertions either promoter first intron. Here, we report a novel Vrn-B1 allele has retrotransposon its conferring spring habit. The VRN-B1 mapped doubled haploid population segregated for winter-spring but derived from two...
Summary TaVrn1 , encoding a MADS‐box transcription factor (TF), is the central regulator of wheat vernalization‐induced flowering. Considering that TF usually works by forming hetero‐ or homodimers, we conducted yeast‐two‐hybrid screening and identified an SVP‐like protein TaVrt2 interacting with TaVrn1. However, specific function biological implication its interaction remained unknown. We validated transgenic experiments their through multiple protein‐binding assays. Population genetic...
Abstract The starch granules of hexaploid wheat (Triticum aestivum) contain a group three proteins known as SGP-1 (starch granule protein-1) proteins, which have apparent molecular masses 100, 108, and 115 kD. nature role these has not been defined previously. We demonstrate that polypeptides are synthases present in both the soluble fraction at early stages endosperm development, but exclusively bound mid late development. A partial cDNA clone encoding fragment 100-kD protein was obtained...
In diploid wheat (Triticum monococcum), and likely in other Triticeae species, the VRN1 gene is essential for initiation of reproductive phase, therefore, a detailed characterization its regulatory regions required to understand this process. A CArG-box (MADS-box-binding site) identified promoter upstream from transcription site has been proposed as critical element vernalization response. This hypothesis was supported by genetic linkage between natural deletions dominant Vrn1 alleles spring...
ABSTRACT Yellow rust, also known as stripe is caused by Puccinia striiformis Westend. f. sp. tritici Eriks (PST) and one of the most common persistent wheat ( Triticum aestivum L.) diseases worldwide. A mapping population recombinant inbred lines from cross ‘Jagger’ (moderately resistant) × ‘2174’ susceptible) was tested at three sites in Washington where predominant races PST‐114 PST‐116 naturally occurred, Rossville, KS, PST‐100 inoculated, Beijing, China, a Chinese rust race CYR32...
The ability of seed to germinate under favorable environmental conditions is critical for seedling emergence, plant establishment, subsequent development and growth adult plants, it controlled by internal genetic factors external factors. Winter wheat in the southern Great Plains often planted six weeks before optimal planting date produce more biomass cattle grazing during winter season. A high germination rate this higher soil temperature environment required specific management system. In...
Crop improvement is a long-term, expensive institutional endeavor. Genomic selection (GS), which uses single nucleotide polymorphism (SNP) information to estimate genomic breeding values, has proven efficient increasing genetic gain by accelerating the process in animal programs. As for crop improvement, with few exceptions, GS applicability remains evaluation of algorithm performance. In this study, we examined factors related line development stage grain yield using hard red winter wheat...
