Functional differentiation of industrial hemp rhizosphere microbiome along environmental gradients.

The southwestern, central, and northeastern regions of China are the primary cultivation areas for industrial hemp. Microorganisms within the soil-root continuum play a crucial role in plant health. However, the mechanisms by which these microbial communities respond to environmental gradients remain unclear.

DNA metabarcode analyses reveal similarities and differences in plant microbiomes of industrial hemp and medicinal in China.

Endophytic bacteria within plant tissues play crucial roles in plant health, stress tolerance, and contribute to the metabolite diversity of host plants. L. is an economically significant plant, with industrial hemp (IH) and medicinal (MC) being the two main cultivars.

Development of recombinase polymerase amplification combined with a lateral flow dipstick assay for rapid and simple detection of Tylenchulus semipenetrans in soil.

Background: Tylenchulus semipenetrans, the causal agent of citrus slow decline disease, is one of the most destructive plant-parasitic nematodes in all citrus-growing regions of the world, causing significant reductions in citrus growth and yield. Accurate and rapid detection of T. semipenetrans is critical for the diagnosis and effective control of the disease.

Bacterial and fungal communities within and among geographic samples of the hemp pest from China.

The hemp flea beetle (Coleoptera: Chrysomelidae: Psylliodes) is a common pest of , including cultivars of both medicinal marijuana and industrial hemp. Both the larval and adult stages of this beetle can cause significant damages to , resulting in substantial crop losses. At present, little is known about the bacterial and fungal community diversity among populations of this pest insect.

Development of a Loop-Mediated Isothermal Amplification Method for the Rapid Detection of .

Brown root rot caused by is a new destructive root disease on many plants such as Gingko, Citrus, kiwifruit, and ramie. The establishment of loop-mediated isothermal amplification (LAMP) technology for detecting can help monitor and control brown root rot quickly, efficiently, and accurately. LAMP technology is known for its simplicity, sensitivity, and speed; and it does not require any specialized equipment - a water bath or a thermoblock is sufficient for isothermal amplifications.

Linking Plant Secondary Metabolites and Plant Microbiomes: A Review.

Plant secondary metabolites (PSMs) play many roles including defense against pathogens, pests, and herbivores; response to environmental stresses, and mediating organismal interactions. Similarly, plant microbiomes participate in many of the above-mentioned processes directly or indirectly by regulating plant metabolism. Studies have shown that plants can influence their microbiome by secreting various metabolites and, in turn, the microbiome may also impact the metabolome of the host plant.

Sphinganine-Analog Mycotoxins (SAMs): Chemical Structures, Bioactivities, and Genetic Controls.

Sphinganine-analog mycotoxins (SAMs) including fumonisins and f. sp. (AAL) toxins are a group of related mycotoxins produced by plant pathogenic fungi in the genus and in f.

Genome Sequence Resource for the Ramie Oomycete Pathogen HF1.

The oomycete is a causative agent of patch canker, damping-off, and crown, stem, and root rot in many economically important plants. HF1 was isolated in China, where it caused brown root rot of ramie, a fiber crop broadly cultivated in Asia. The genome of HF1 was sequenced by a combination of technologies producing short (Illumina HiSeq X) and long (PacBio RS) reads.

Molecular Diagnostics and Detection of Oomycetes on Fiber Crops.

Fiber crops are an important group of economic plants. Traditionally cultivated for fiber, fiber crops have also become sources of other materials such as food, animal feed, cosmetics and medicine. Asia and America are the two main production areas of fiber crops in the world.

Mitochondrial COI Sequence Variations within and among Geographic Samples of the Hemp Pest from China.

The hemp flea beetle (Coleoptera: Chrysomelidae: Psylliodes) is a common pest of , including cultivars of both industrial hemp and medicinal marijuana. Both the larval and adult stages of this beetle can cause significant damages to , resulting in substantial crop losses. At present, little is known about the populations of this pest, including its genetic diversity.

Molecular Diagnostics and Pathogenesis of Fungal Pathogens on Bast Fiber Crops.

Bast fibers and products derived from them are undergoing a resurgence in demand in the global market. However, fungal diseases have become an important factor limiting their yield and quality, causing devastating consequences for the production of bast fiber crops in many parts of the world. Thus, there is a high demand for effective control and prevention strategies against fungal pathogens.

A proper PiCAT2 level is critical for sporulation, sporangium function, and pathogenicity of Phytophthora infestans.

Catalase is present in prokaryotic and eukaryotic organisms and is important for the protective effects of the antioxidant system against free radicals. Many studies have confirmed that catalase is required for the growth, development, and pathogenesis of bacteria, plants, animals, and fungi. However, there has been relatively little research on the catalases in oomycetes, which form an important group of fungus-like eukaryotes that produce zoosporangia.
