Despite the fact that roots are organs most subject to microbial interactions, very little is known about response of microbe-associated molecular patterns (MAMPs). By monitoring transcriptional activation beta-glucuronidase reporters and MAMP-elicited callose deposition, we show three MAMPs, flagellar peptide Flg22, peptidoglycan, chitin, trigger a strong tissue-specific in Arabidopsis thaliana roots, either at elongation zone for Flg22 peptidoglycan or mature parts chitin. Ethylene...
Allergic rhinitis affects the quality of life millions people worldwide. Air pollution not only causes morbidity, but nearly 3 million per year die from unhealthy indoor air exposure. Furthermore, allergic and interact. This report summarizes discussion an International Expert Consensus on management aggravated by pollution. The begins with a review outdoor pollutants followed epidemiologic evidence showing impact climate change upper airway rhinitis. Mechanisms, particularly oxidative...
Phytophthora is an important, highly destructive pathogen of many plants, which causes considerable crop loss, especially durians in Thailand. In this study, we selectively isolated Streptomyces from the rhizosphere soil with a potent anti-oomycete activity against palmivora CbP03. Two strains (SNN087 and SNN289) demonstrated exceptional plant growth-promoting properties pot experiment. Both promoted mung bean (Vigna radiate) growth effectively both sterile non-sterile soils. Metagenomic...
This cross-sectional study aimed to investigate the prevalence and clinical characteristics of cross-reactivity co-allergy other plant foods among adult patients with IgE-mediated banana allergy in Thailand. A structured questionnaire was used assess reactivity, diagnoses were based on reactions occurring within 2 years onset, 3 h intake, confirmed by allergists. Among 133 participants, most commonly associated kiwi (83.5%), avocado (71.1%), persimmon (58.8%), grapes (44.0%), durian (43.6%)....
Mosquito allergy is common in tropical countries but remains under-diagnosed. This may be due to the lack of knowledge and diagnostic tools for mosquito allergens. We aimed characterize allergens from species investigate IgE reactivity mosquito-allergic patients salivary gland proteins these mosquitoes. Salivary extract (SGE) 4 species, highly distributed tropics, including Aedes aegypti, albopictus, Culex quinquefasciatus, Anopheles dirus b, were studied. SGE-specific IgG ELISA developed,...
Durian (Durio zibethinus L.) is susceptible to Phytophthora palmivora, which causes rot disease, leading significant yield loss. This study aimed investigate local defense responses of durian P. palmivora and compare the infection dynamics high virulence (HV) low (LV) isolates. leaves on 1-year-old seedlings were inoculated with mycelial plugs. Symptoms observed within 24 h. The HV-isolate was more aggressive, larger lesions, earlier denser colonization, higher sporulation. lifestyle related...
Allergic rhinitis (AR) is a prevalent public health concern globally, significantly impacting quality of life. In Thailand, the prevalence AR rising, with grass and weed pollen identified as primary outdoor triggers. This study aimed to (1) assess patterns sensitization in Thai patients (2) investigate correlations between demographics/clinical data SPT results. A total 121 individuals aged ≥18 years clinically diagnosed were recruited. Skin prick testing (SPT) was performed using panel...
Aeropollen can induce detrimental effects, particularly in respiratory airways. Monitoring local aeropollen is essential for the management of pollen allergic patients each area. However, without resources constant monitoring, counts are subjected to biases imposed by choices sampling season, time collection, and location. Therefore, effects these factors must be better understood. This study investigated dynamics types through seasonal variation, diurnal cycle different heights from ground...
Metalaxyl is an effective approach to control Phytophthora palmivora infection in durian plantation. However, inappropriate metalaxyl usage may increase production cost, pathogen with fungicide resistance, and environmental toxicity. This study established validated a simple reproducible procedure measure concentration the leaf using HPLC. Linearity of detection ranged from 1–100 µg/mL. The limits (LOD) quantification (LOQ) were 0.27 0.91 µg/mL, respectively. extraction method gave recovery...
Stress-induced effect on Arabidopsis thaliana seeds due to high-intensity electrical pulses is described. The pulsed electric field (PEF) treatment system was constructed under the concept of electroporation deliver 10-nanosecond, 5-Hz pulse train with energy density per up 4 kJ ·kg (-1). analysis growth responses revealed that optimal specific ∼ 1 · kg (-1) delivered positive early significant enhancement in germination percentage and leaf area expansion. same energy, addition, contributed...
Background and objectives: Group-1 grass allergens or beta-expansins (EXPBs) are major from pollen of all species. Previous studies showed that they highly conserved (64-85%) in Pooideae species, which found mostly the temperate regions. However, information about group-1 common species subtropical areas is still lacking. This study aimed to assess sequence diversity areas, especially Southeast Asia. Materials Methods: were cloned eight using a single set primers. Sequences analyzed IgE IgG4...
Group 1 grass pollen allergens, or beta-expansins, are the most important major allergens from tropical/subtropical grasses.This study aimed to investigate sequence similarity and immunoreactivity of group para (Urochloa mutica).Three isoforms (Uro m 1.01, Uro 1.02, 1.03) were cloned cDNA pollen.The acidic-neutral rUro 1.01 1.02 could effectively inhibited beta-expansins in extract Bermuda Johnson grasses, suggesting that these be cross-reacting among grasses.In contrast, basic isoform 1.03...
Background: Pollen of grasses in Chloridoideae and Panicoideae subfamilies is a major source grass group-1 allergens tropical/subtropical areas.Previously, most studies subtropical pollen have focused on Cynodon dactylon (Bermuda grass-Chloridoideae) Sorghum halepense (Johnson grass-Panicoideae).However, little information available about allergenicity from Zoysia matrella (Manila or grass-Chloridoideae), which among the popular turfgrasses areas.Objective: This study aimed to investigate...
Periglandula is a fungal genus that associated with plants in the family Convolvulaceae. They produce medicinally important constituents called ergot alkaloids, which are stored their host plants. Previously, fungi were reported to mainly interact young leaves and seeds of Convolvulaceae species. However, knowledge about how alkaloid-producing still lacking. Therefore, we investigated interaction fungus different plant parts Ipomoea asarifolia, using molecular, histochemical, anatomical...
Abstract Ergot alkaloids are renowned for their pharmacological significance and were historically attributed to fungal symbioses with cereal crops grasses. Recent research uncovered a symbiotic relationship between the fungus Periglandula ipomoea Ipomoea asarifolia (Convolvulaceae), revealing new source ergot alkaloid synthesis. While past studies have emphasized storage of both in leaves seeds, recent work has found they also occur other plant parts. This study aimed (1) examine expression...
