Genetic analysis identifies key loci for traits and resistance in Qinghai plateau wheat F populations.

The Qinghai Plateau's high-altitude conditions present significant challenges for wheat cultivation, demanding varieties with enhanced adaptability and stress resistance. However, the genetic basis for key traits like grain yield and stress tolerance in wheat adapted to these conditions remains poorly understood. This knowledge is crucial for developing wheat varieties that can thrive in the harsh environment of the Qinghai Plateau.

Development of a semi-dwarf dominant genic male sterile wheat with seed red fluorescence as a visible marker.

Unlabelled: Taigu genic male-sterile wheat, containing the dominant gene () , shows completely male-sterility in different genetic background and under various environments. The development of Aibai wheat with tightly linked and (), offers possibility for identifying the male-sterile plants by investigation of reduced plant height. However, due to the extreme dwarfism of Aibai wheat caused by , it inhabits a shadowed microenvironment caused by its fertile sibling plants.

The complete chloroplast genome sequence of , a widespread grass in Tibet, China.

The complete chloroplast genome of was sequenced and reported here. The total genome size was 138,294 bp in length, containing a large single-copy region of 81,229 bp, a small single-copy region of 12,419 bp, and a pair of inverted repeat regions of 22,288 bp. The GC content of chloroplast genome was 38.

Identification of Two New Loci for Adult Plant Resistance to Leaf Rust and Stripe Rust in the Chinese Wheat Variety 'Neimai 836'.

The characterization of leaf rust (caused by ) and stripe rust (caused by f. sp. ) resistance genes is the basis for breeding resistant wheat varieties and managing epidemics of these diseases in wheat.

Genome-Wide Mapping of Adult Plant Resistance to Leaf Rust and Stripe Rust in CIMMYT Wheat Line Arableu#1.

Leaf (brown) rust (LR) and stripe (yellow) rust (YR), caused by and f. sp. , respectively, significantly reduce wheat production worldwide.

Four Consistent Loci Confer Adult Plant Resistance to Leaf Rust in the Durum Wheat Lines Heller#1 and Dunkler.

The durum wheat lines Heller#1 and Dunkler from the International Maize and Wheat Improvement Center Global Wheat Program showed moderate and stable adult plant resistance to leaf rust under high disease pressure over field environments in northwestern Mexico. Leaf rust phenotyping was performed on two recombinant inbred line (RIL) populations derived from crosses of Heller#1 and Dunkler with the susceptible parent Atred#2, conducted under artificially induced epidemics in 2013, 2014, 2015, and 2016. The Atred#2 × Heller#1 and Atred#2 × Dunkler populations were genotyped by single nucleotide polymorphism (SNP) platforms and diversity arrays technology markers, respectively.

Development and Application of Transposable Element-Based Chromosomal Markers for the St Genome in Triticeae.

The St genome, originating from Pseudoroegneria (Nevski) Á. Löve, plays an important role in Triticeae. In this study, the Pseudoroegneria stipifolia genome (2n = 2x = 14, StSt) was screened to identify sequences that could be used for FISH.

Cold-dependent alternative splicing of a Jumonji C domain-containing gene MtJMJC5 in Medicago truncatula.

Histone methylation is an epigenetic modification mechanism that regulates gene expression in eukaryotic cells. Jumonji C domain-containing demethylases are involved in removal of methyl groups at lysine or arginine residues. The JmjC domain-only member, JMJ30/JMJD5 of Arabidopsis, is a component of the plant circadian clock.

Developmental Stage-Specific Hepatocytes Induce Maturation of HepG2 Cells by Rebuilding the Regulatory Circuit.

On the basis of their characteristics, we presume that developmental stage-specific hepatocytes should have the ability to induce maturation of hepatoma cells. A regulatory circuit formed by hepatocyte nuclear factor (HNF)-4α, HNF-1α, HNF-6 and the upstream stimulatory factor (USF-1) play a key role in the maturation of embryonic hepatocytes; however, it is unclear whether the regulatory circuit mediates the embryonic induction of hepatoma cell maturation. In this study, 12.

Effect of degradation intensity on grassland ecosystem services in the alpine region of Qinghai-Tibetan Plateau, China.

The deterioration of alpine grassland has great impact on ecosystem services in the alpine region of Qinghai-Tibetan Plateau. However, the effect of grassland degradation on ecosystem services and the consequence of grassland deterioration on economic loss still remains a mystery. So, in this study, we assessed four types of ecosystem services following the Millennium Ecosystem Assessment classification, along a degradation gradient.

Protein nitration promotes inducible nitric oxide synthase transcription mediated by NF-κB in high glucose-stimulated human lens epithelial cells.

Although an important event in hyperglycaemia-induced oxidative stress is the nuclear factor-kappa b (NF-κB)-activated inducible nitric oxide synthase (iNOS) expression, the underlying mechanism is not fully characterized. Peroxynitrite, formed from NO and superoxide, can induce multiple proteins nitration, even including NF-κB and iNOS, to alter their functions. In this study, we found high glucose caused conspicuous nitration of nuclear NF-κB p65 and its co-activator p300 in human lens epithelial cells.
