Effects of Streptomyces sp. HU2014 inoculation on wheat growth and rhizosphere microbial diversity under hexavalent chromium stress
Ecotoxicol Environ Saf. 2024 Apr 15;276:116313. doi: 10.1016/j.ecoenv.2024.116313. Online ahead of print.ABSTRACTWheat (Triticum aestivum L.) is a major foodstuff for over 40% of the world's population. However, hexavalent chromium [Cr(VI)] in contaminated soil significantly affects wheat production and its ecological environment. Streptomyces sp. HU2014 was first used to investigate the effects of Cr (VI) stress on wheat growth. We analyzed the Cr(VI) concentration, physicochemical properties of wheat and soil, total Cr content, and microbial community structures during their interactions. HU2014 reduced the toxicity of C...

Ozone variability, its formation potential and crops losses in the himalayan foothills
AbstractSurface ozone observations in Doon Valley (Dehradun: 30.3oN, 78.0oE, 700 m), which acts as a bridge between the Himalayas and the Indo-Gangetic Plain, showed daytime higher values, suggesting a typical urban behaviour in proximity of the Himalayas. Ozone exhibited a maximum in spring (49.2 ± 24.8 ppbv in May) with an hourly average of more than 110 ppbv, followed by a secondary maximum in autumn and the lowest level occurring in the summer-monsoon (~ 13 ppbv in July-August). Ozone levels exceeded the 8-hour National Air Quality Standard limit (50 ppbv) throughout the year, except in July-September. The obs...

Whether and when to biopsy coeliac patients: A never-ending story
Coeliac disease (CD) is an autoimmune enteropathy that primarily affects the small intestine, causing mucosal inflammation and variable villous atrophy. It occurs in genetically predisposed subjects following the ingestion of gluten, a protein complex of cereals such as wheat, barley, rye, whose main fractions are prolamins (including gliadin) and gluten [1].

Fecal calprotectin levels in patients with non-celiac wheat sensitivity: a proof of concept
AbstractSome data suggest the existence of intestinal inflammation in patients with non-celiac wheat sensitivity (NCWS). We aimed to verify whether fecal calprotectin (FCP), a marker of intestinal inflammation, could be used to confirm this inflammatory status and to test its diagnostic performance in differentiating NCWS from irritable bowel syndrome/functional dyspepsia (IBS/FD). We conducted a multicenter study, comparing NCWS patients, diagnosed by a double-blind placebo-controlled wheat challenge, with IBS/FD subjects. In the retrospective phase, FCP values were analyzed to define the prevalence of its positivity an...

Peroxidase like Zn doped Prussian blue facilitates salinity tolerance in winter wheat through seed dressing
This study synthesized a highly active nanozyme catalyst known as ZnPB (Zn-modified Prussian blue) to improve the yield and quality of wheat in saline soil. According to the Michaelis-Menten equation, ZnPB demonstrates exceptional peroxidase-like enzymatic activity, thereby mitigating oxidative damage caused by salt stress. Additionally, studies have shown that the ZnPB nanozyme is capable of regulating intracellular Na+ efflux and K+ retention in wheat, resulting in a decrease in proline and soluble protein levels while maintaining the integrity of macromolecules within the cell. Consequently, field experiments demonstrat...

Transcriptome and proteome analyses reveal that upregulation of GSTM2 by allisartan improves cardiac remodeling and dysfunction in hypertensive rats
In conclusion, the present study demonstrated that allisartan can effectively control blood pressure in SHRs, and improves cardiac remodeling and cardiac dysfunction. Allisartan may also upregulate the expression levels of GSTM2 in the hearts of SHRs and significantly affect glutathione metabolism, as determined by transcriptome and proteome analyses. The cardioprotective effect of allisartan may be mediated through activation of the PI3K-AKT-Nrf2 signaling pathway, upregulation of GSTM2 expression and reduction of cardiomyocyte apoptosis in SHRs.PMID:38590561 | PMC:PMC11000455 | DOI:10.3892/etm.2024.12508 (Source: Experim...

Investigating Circadian Gating of Temperature Responsive Genes
Methods Mol Biol. 2024;2795:213-225. doi: 10.1007/978-1-0716-3814-9_20.ABSTRACTUnderstanding gene expression dynamics in the context of the time of day and temperature response is an important part of understanding plant thermotolerance in a changing climate. Performing "gating" experiments under constant conditions and light-dark cycles allows users to identify and dissect the contribution of the time of day and circadian clock to the dynamic nature of stress-responsive genes. Here, we describe the design of specific laboratory experiments in plants (Arabidopsis thaliana and bread wheat, Triticum aestivum) to investigate ...

TaWRKY50-TaSARK7 module-mediated cysteine-rich protein phosphorylation suppresses the programmed cell death response to Chinese wheat mosaic virus infection
Virology. 2024 Apr 5;595:110071. doi: 10.1016/j.virol.2024.110071. Online ahead of print.ABSTRACTWRKY transcription factors are widely involved in plant responses to biotic and abiotic stresses. However, there is currently a limited understanding of the regulation of viral infection by WRKY transcription factors in wheat (Triticum aestivum). The WRKY transcription factor TaWRKY50 in group IIb wheat exhibited a significant response to Chinese wheat mosaic virus infection. TaWRKY50 is localized in the nucleus and is an activating transcription factor. Interestingly, we found that silencing TaWRKY50 induces cell death followi...

Halophytic Bacterial Endophyte Microbiome from Coastal Desert-Adapted Wild Poaceae Alleviates Salinity Stress in the Common Wheat Triticum aestivum L
Curr Microbiol. 2024 Apr 9;81(5):132. doi: 10.1007/s00284-024-03649-1.ABSTRACTAbiotic stresses threaten the strategic crops of Poaceae (Gramineae) worldwide. Habitat-adapted microbiome of wild plants has the potential to alleviate abiotic stresses in alternate hosts. Persian Gulf's coastal deserts are colonized by halophyte plants hosting habitat-adapted halophytic microbiota. Here, endophytic bacteria from wild Poaceae in coastal deserts of the north Persian Gulf at Hormozgan province, Iran, were isolated and screened for mitigating salinity stress in wheat. Accordingly, seven dominant species of wild Poaceae in the regio...

Genes, Vol. 15, Pages 475: Advances in Understanding Fusarium graminearum: Genes Involved in the Regulation of Sexual Development, Pathogenesis, and Deoxynivalenol Biosynthesis
g
Jiangang Kang
The wheat head blight disease caused by Fusarium graminearum is a major concern for food security and the health of both humans and animals. As a pathogenic microorganism, F. graminearum produces virulence factors during infection to increase pathogenicity, including various macromolecular and small molecular compounds. Among these virulence factors, secreted proteins and deoxynivalenol (DON) are important weapons for the expansion and colonization of F. graminearum. Besides the presence of virulence factors, sexual reproduction is also crucial for the infection process of F. graminearum and is indisp...
