Mutations across Diverse Domains of CjXDR1 Lead to Multidrug Resistance in .

Recently, has emerged as a significant pathogen threatening turfgrass, and its escalating resistance to multiple drugs often undermines field interventions. This study highlighted the critical role of the fungus-specific transcription factor CjXDR1 (formerly ShXDR1) in regulating multidrug resistance (MDR) in . This was demonstrated through experiments involving CjXDR1-knockout and CjXDR1-complemented strains.

A rapid real-time PCR assay for detecting Microdochium paspali causing sparse leaf patch on seashore paspalum and in environmental samples.

Background: Sparse leaf patch (SLP) is one of the most significant diseases affecting seashore paspalum (Paspalum vaginatum Sw.), caused by Microdochium paspali. Fast and accurate detection of this pathogen is crucial for effective disease management.

Genome-wide transcriptional analyses of isolates associated with multi-drug resistance.

Emerging multidrug resistance (MDR) in spp. is a huge challenge to the management of dollar spot (DS) disease on turfgrass. Insight into the molecular basis of resistance mechanisms may help identify key molecular targets for developing novel effective chemicals.

Comparative genomics and transcriptome analysis reveals potential pathogenic mechanisms of on seashore paspalum.

The sparse leaf patch of seashore paspalum ( Sw.) caused by seriously impacts the landscape value of turf and poses a challenge to the maintenance and management of golf courses. Little is known about the genome of or the potential genes underlying pathogenicity.

Activity of the Succinate Dehydrogenase Inhibitor Fungicide Benzovindiflupyr Against spp.

Dollar spot (DS), caused by spp. (formerly ), is one of the most important diseases of turfgrasses worldwide. Benzovindiflupyr, a pyrazole carboxamide fungicide belonging to succinate dehydrogenase inhibitors, was recently registered for DS control.

Genome Resources for Four Species Causing Dollar Spot on Diverse Turfgrasses.

Dollar spot (DS) is a destructive fungal disease impacting almost all warm- and cool-season turfgrasses worldwide. Multiple fungal species in the genus are causal agents of DS. Here, we present whole-genome assemblies of nine fungal isolates in the genus , including four species (, , , and ) causing DS on seashore paspalum ( Sw.

Distribution and Prevalence of Plant-Parasitic Nematodes of Turfgrass at Golf Courses in China.

We sampled 127 turfgrass soil samples from 33 golf courses in NC, EC, and SC for plant-parasitic nematodes (PPNs). PPNs were extracted from soil samples using the shallow dish method and were identified at the genus or species levels with a combination of morphological and molecular methods. The results revealed 41 species of nematode belonging to 20 genera and 10 families.

Fluorescent salicylaldehyde hydrazone as selective chemosensor for Zn2+ in aqueous ethanol: a ratiometric approach.

4-N,N-diethylaminosalicylaldehyde hydrazone Schiff base (1) and its analogues (2-6) were synthesized and characterized by NMR, MS and elemental analysis. Compound 1 exhibited ratiometric fluorescent response to Zn(2+) over other metal ions in aqueous ethanol solution with neutral buffer. The complexation ratio, site and constant and the effect of pH value and water fraction on its fluorescent response to Zn(2+) were investigated.

Bifunctional Au-Fe3O4 nanoparticles for protein separation.

In this article, we report the synthesis of bifunctional Au-Fe(3)O(4) nanoparticles that are formed by chemical bond linkage. Due to the introduction of Au nanoparticles, the resulting bifunctional Au-Fe(3)O(4) nanoparticles can be easily modified with other functional molecules to realize various nanobiotechnological separations and detections. Here, as an example, we demonstrate that as-prepared Au-Fe(3)O(4) nanoparticles can be modified with nitrilotriacetic acid molecules through Au-S interaction and used to separate proteins simply with the assistance of a magnet.

New fluorescent rhodamine hydrazone chemosensor for Cu(II) with high selectivity and sensitivity.

[reaction: see text] A new fluorescent probe, salicylaldehyde rhodamine B hydrazone (1), was synthesized and displayed selective Cu(II)-amplified absorbance and fluorescence emission above 500 nm in neutral buffered media. Upon the addition of Cu(II), the spirolactam ring of 1 was opened and a 1:1 metal-ligand complex was formed. The detection of Cu(II) by 1 at a lower micromolar level was successful even in buffered water.
