The Bacillus velezensis GJ-7 strain isolated from the rhizosphere soil of Panax notoginseng showed high nematicidal activity and therefore has been considered a biological control agent that could act against root-knot nematode Meloidogyne hapla. However, little was known about whether produce volatile organic compounds (VOCs) were effective in biocontrol M. In this study, we evaluated VOCs produced by fermentation three-compartment Petri dishes. results revealed mortality rates hapla J2s...
Root rot disease is a major threat to the sustainable production of Panax notoginseng. Tetramycin has broad-spectrum fungicidal efficacy, low toxicity, and high efficiency, However, prevention control root P. notoginseng specific mechanism action are still unclear. In this paper, combination indoor pot experiments was used assess effectiveness tetramycin at alleviating challenges encountered by Amplicon sequencing, metagenomic analysis with microbial verification were investigate...
Root-knot nematodes (RKNs) are soil-borne pathogens that severely affect Panax notoginseng growth and productivity. Thus, there is an urgent need for biological control agents or green nematicides to root-knot nematodes. Rhizosphere bacteria can effectively RKNs through different mechanisms. In this study, the three rhizosphere Bacillus strains, isolated from root of P. notoginseng, were evaluated nematicidal activity efficacy against addition, we also colonization ability two bacterial...
Panax notoginseng (P. notoginseng) is an invaluable perennial medicinal herb. However, the roots of P. are frequently subjected to severe damage caused by root-knot nematode (RKN) infestation. Although we have observed that possessed adult-plant resistance (APR) against RKN disease, defense response mechanisms disease in different age groups remain unexplored. We aimed elucidate at stages development infection employing transcriptome, metabolome, and histochemistry analyses. Our findings...
The occurrence of root-knot nematode disease has seriously constrained the development Chinese herbal medicine industry. China is one largest producers Polygonatum sibiricum and Peucedanum praeruptorum in world, but unidentified nematodes have become important pests these two medicines China. Both morphological characteristics molecular identification were used to identify nematodes. results showed that Meloidogyne incognita M. arenaria causal species infection P. sibiricum, hapla was...

Objective: To explore the safety and feasibility of colonoscopy - assisted transanal minimally invasive surgery via glove port (CA-TAMIS-GP) in treatment early rectal tumors. Methods: A total 67 patients evaluated as tumors (adenoma limited within mucosal layer) with diameter ≤4.0 cm at Department Anal-Colorectal Surgery, Hangzhou Third People's Hospital from July 2013 to March 2017 were prospectively enrolled study. Benign diagnosed by preoperative imaging all distance anal edge 4 20 cm....
Maidong (Ophiopogon japonicus) is a perennial evergreen plant of the Asparagaceae, occurring mainly in China, Japan, Vietnam, and India. It grows damp place on hillside below 2000 meters above sea level, under forest or beside stream;It has been widely cultivated Sichuan ofhina for medicinal uses; it included Chinese Pharmacopoeia. During April 2019, plants exhibiting symptoms stunting, leaf wilting, multiple galls roots associated with root-knot nematode (Meloidogyne sp.) were detected...
Abstract In September 2020, samples of galled roots with rhizosphere soil were collected from declining Gentiana macrophylla in Yulong County, China. The pathogenic nematodes identified by observing morphological characteristics females, second-stage juveniles and perineal pattern, sequence alignments, specific amplification characterized amplified region (SCAR). results showed that the pattern this nematode was round or oval, dorsal arch moderately high low, one side both lateral field...
Bletilla striata Rchb.f., is a perennial herbaceous bulbous plant known as the Chinese ground or hyacinth orchid classified in Orchidaceae. It native to southeast Asia and mainly distributed China, Japan northern Myanmar (He et al. 2017). has functions of astringent hemostasis analgesia, can also be used treat traumatic bleeding, ulcers, swelling chapped skin. Therefore, it occupies an important position traditional medicine (Xu 2019). In June 2023, three farmers Mengzi (103.39°N, 23.21°E),...
Root-knot nematodes (Meloidogyne spp.) are soil-borne pathogens that can cause severe damage to agricultural production. The most common approaches prevent root-knot nematode infections based on crop rotation with non-host plants, use of chemical insecticides, biological control methods, and nematode-antagonistic or trap plants. Marigolds (Tagetes erecta) used as nematode-killing but there is controversy over the mechanism through which they nematodes. This study confirmed marigold...
Growth of the Chinese herbal medicine industry has resulted in several new pests and diseases. China is one world largest producers monkshood (Aconitum carmichaelii Debx.), but an unidentified root-knot nematode become a significant pest southwestern provinces Yunnan Sichuan. Morphological characteristics ribosomal DNA-internal transcribed spacer D2-D3 region 28S RNA gene sequences were used to identify as Meloidogyne hapla. Through investigation, this first report M. hapla infecting Sichuan...
The rhizosphere bacteria Bacillus velezensis GJ-7, as a biological control agent (BCA), has significant effects on Meloidogyne hapla, and strong colonization ability in the root of Panax notoginseng. In this study, we conducted comparative transcriptome analysis using P. notoginseng plant roots treated with B. GJ-7 or sterile water alone combination M. hapla inoculation to explore interactions involving plant, hapla. Four treatments from were sequenced, twelve high-quality total clean bases...
Abstract Root-knot nematode (RKN) is a soil-borne pathogen that severely damages Panax notoginseng . It has been recently shown intercropping P. in forests constitutes an innovative system can promote growth and suppress the spread of disease. However, there little research on interspecific interaction between pine trees Here, two years field experiments were designed to explore effects RKN infestation –pine tree saponin synthesis The results showed could significantly reduce root biomass,...
