Dissection of genomic drivers of spike morphology changes in wheat by high-throughput phenotyping.

Spike morphology is crucial for wheat (Triticum aestivum L.) yield and environmental adaptation. We developed a high-throughput phenotyping platform to dissect spike morphology traits based on 54 traits in 1,359 wheat accessions.

Position sensitive silicon photomultipliers with an intrinsic continuous resistive layer for charge division.

Position sensitive silicon photomultipliers that utilize an intrinsic continuous resistive layer (CRL SiPMs) for charge division are reviewed, and new developments of one-dimensional (1D) CRL SiPMs are reported. This study compares and analyzes the position and timing characteristics of three 1D CRL SiPM configurations: square ring (SR) electrodes with microcell sizes of 15 μm and 20 μm, and a dual parallel side strip (DPSS) electrode with a 10 μm microcell size. The position resolution degrades as microcell size increases, whereas the position measurement error remains independent of microcell size.

Genomics-driven discovery of superior alleles and genes for yellow rust resistance in wheat.

Yellow rust (YR), caused by Puccinia striiformis f. sp. tritici, poses a significant threat to wheat production worldwide.

Stripe rust fungi hijack a host transcriptional repressor to induce TaSWEET14d for enhanced sugar uptake in wheat.

Biotrophic pathogens rely on host plants for carbon acquisition, making plant sugar transporters, such as Sugars Will Eventually be Exported Transporters (SWEETs), key targets in sugar competition between plants and pathogens. In this study, we identified as a f. sp.

Wheat TaNADPO Promotes Spot Blotch Resistance.

Bipolaris sorokiniana is a prevalent fungal pathogen that resides in the soil and affects various parts of wheat, leading to diseases such as spot blotch, common root rot, head blight and black point. The genetic mechanisms that confer resistance in wheat against this pathogen are not completely known. In this research, 1302 wheat germplasms from around the world were evaluated for resistance to spot blotch at the seedling stage, and it was found that merely 3.

Haplotype-resolved telomere-to-telomere genome assembly of the dikaryotic fungus pathogen Rhizoctonia cerealis.

Rhizoctonia cerealis, the causal agent of sharp eyespot, is a highly destructive pathogen of wheat. Despite its global importance, the genetic and molecular mechanisms underlying virulence of R. cerealis remain poorly understood.

Rapid isolation of Yr9 via MutIsoSeq and QTL analysis of durable stripe rust resistance in wheat cultivar Xingzi 9104.

The fungus Puccinia striiformis f. sp. tritici (Pst) is the causal agent of wheat stripe rust which constitutes a major limitation to wheat production.

TaLAC129 is a negative regulator of arbuscular mycorrhizal symbiosis but enhanced the growth and yield of bread wheat.

Arbuscular mycorrhizal (AM) symbiosis enhances nutrient acquisition and stress resilience in plants, yet the genetic mechanisms regulating this interaction in wheat remain poorly understood. This study explores the variation in AM colonization rates across a diverse set of wheat varieties and aims to identify key genes that regulate the wheat-AM symbiosis. Understanding these molecular mechanisms is crucial for improving nutrient uptake efficiency and stress resistance in wheat breeding programs.

Genome-Wide Association Study of Grain Manganese Content in Bread Wheat ( L.) Under Four Environments.

Microelements play important roles to maintain the normal metabolism of the human body, and deficiency of microelements always leads to a serious diseases. Manganese (Mn) is an essential microelement for the human body. However, the mechanism for regulating grain Manganese (Mn) content (GMnC) in wheat is rarely studied.

The combination of a QTL on chromosome arm 4BL and Yr29 provides durable resistance with no significant yield penalty. Wheat stripe rust or yellow rust (YR), caused by Puccinia striiformis f. sp.

Development and application of the GenoBaits WheatSNP16K array to accelerate wheat genetic research and breeding.

Single-nucleotide polymorphisms (SNPs) are widely used as molecular markers for constructing genetic linkage maps in wheat. Compared with available SNP-based genotyping platforms, a genotyping by target sequencing (GBTS) system with capture-in-solution (liquid chip) technology has become the favored genotyping technology because it is less demanding and more cost effective, flexible, and user-friendly. In this study, a new GenoBaits WheatSNP16K (GBW16K) GBTS array was designed using datasets generated by the wheat 660K SNP array and resequencing platforms in our previous studies.

Variation in TaSPL6-D confers salinity tolerance in bread wheat by activating TaHKT1;5-D while preserving yield-related traits.

Na exclusion from above-ground tissues via the Na-selective transporter HKT1;5 is a major salt-tolerance mechanism in crops. Using the expression genome-wide association study and yeast-one-hybrid screening, we identified TaSPL6-D, a transcriptional suppressor of TaHKT1;5-D in bread wheat. SPL6 also targeted HKT1;5 in rice and Brachypodium.

Using UAV-Based Temporal Spectral Indices to Dissect Changes in the Stay-Green Trait in Wheat.

Stay-green (SG) in wheat is a beneficial trait that increases yield and stress tolerance. However, conventional phenotyping techniques limited the understanding of its genetic basis. Spectral indices (SIs) as non-destructive tools to evaluate crop temporal senescence provide an alternative strategy.

Identification of Two Novel QTL for Fusarium Head Blight Resistance in German Wheat Cultivar Centrum.

Fusarium head blight (FHB) is a devastating disease that occurs in warm and humid environments. The German wheat 'Centrum' has displayed moderate to high levels of FHB resistance in the field for many years. In this study, an F recombinant inbred line (RIL) population derived from cross 'Centrum' × 'Xinong 979' was evaluated for FHB response following point inoculation in five environments.

Host genotype-specific rhizosphere fungus enhances drought resistance in wheat.

Background: The severity and frequency of drought are expected to increase substantially in the coming century and dramatically reduce crop yields. Manipulation of rhizosphere microbiomes is an emerging strategy for mitigating drought stress in agroecosystems. However, little is known about the mechanisms underlying how drought-resistant plant recruitment of specific rhizosphere fungi enhances drought adaptation of drought-sensitive wheats.
