From a screen of 36 plant-associated strains of Burkholderia spp., we identified 24 strains that suppressed leaf and pseudobulb necrosis of orchid caused by B. gladioli. To gain insights into the mechanisms of disease suppression, we generated a draft genome sequence from one suppressive strain,
Prosthechea karwinskii (Mart.) J.M.H. Shaw is a Mexican orchid used in traditional medicine by some indigenous communities to treat issues related to inflammation (cough, wounds, burns, and diabetes). Pharmacological research of this orchid could validate its therapeutic uses and We report the occurrence of Bacillus amyloliquefaciens in vanilla orchids (Vanilla phaeantha) and cultivated hybrid vanilla (V. planifolia × V. pompona) as a systemic bacterial endophyte. We determined with light microscopy and isolations that tissues of V. phaeantha and the cultivated hybrid were
In November 2003, two Phalaenopsis orchids from two different nurseries with symptoms of chlorotic rings on leaves were observed in Changhua County of central Taiwan. Symptomatic plants were collected and examined for the presence of viruses. Electron microscopic examination of ultrathin sections of
Background: Brasilonema is a cyanobacterial genus found on the surface of mineral substrates and plants such as bromeliads, orchids and eucalyptus. B. octagenarum stands out among cyanobacteria due to causing damage to the
In February 2013, an ornamental waxflower (Hoya calycina Schlecter) with leaves displaying concentric chlorotic and necrotic rings surrounding sunken, necrotic lesions typical of tospovirus infection was observed at a community garden in Honolulu, HI. Symptomatic leaf tissue tested negative for
Richardia brasiliensis (Rubiaceae), also known as white eye or 'poaia-branca' in Brazil, is an important agricultural weed in the tropics (2). Relatively little is known about diseases affecting this species. In March 2013, all of the plants of this weed species invading an orchid plantation in Nova
In November 2007, leaves of 79 Phalaenopsis and two Dendrobium orchid plants in a nursery in Yunnan Province showed large chlorotic/necrotic ringspot symptoms. Eight symptomatic leaves from Phalaenopsis and two from Dendrobium were sampled and tested for Impatiens necrotic spot virus (INSV), Tomato
BACKGROUND
The Orchidaceae family is one of the largest families of flowering plants. Orchids are widely used for the traditional herbal medicine, acting as aphrodisiac, antisepic, antimicrobial, anti-cancer agent, etc.
OBJECTIVE
This study was designed to elucidate the anti-inflammatory,
Spiranthes sinensis is an east Asian wild orchid used in Chinese folk medicine. In this study, an ethyl acetate fraction from S. sinensis(SSE) was found to suppress the production of LPS-stimulated inflammatory mediators in RAW264.7 cells and BALB/c mice. SSE inhibited the production of
The use of orchids in herbal medicine has a very long history. Dendrobium species are known to produce a variety of secondary metabolites such as phenanthrens, bibenzyls, fluorenones and sesquiterpenes, and alkaloids and are responsible for their wide variety of medicinal properties. For decades,
Scrub typhus is becoming a clinically important cause of acute undifferentiated febrile illness in Taiwan. The incubation period is between 6 and 21 days after exposure. It is transmitted by chiggers (larva of trombiculid mite) in long grasses and in dirt-floor homes, with infection characterized by
Local chlorotic spots resembling early lesions characteristic of citrus leprosis (CL) were observed in leaves of two sweet orange (Citrus sinensis L.) trees in Teresina, State of Piauí, Brazil, in early 2017. However, despite the similarities, these spots were generally larger than those of a
Citrus is a rapidly expanding fruit crop in Panama with a planted area of approximately 14,000 ha, with the crop destined for both table and juice industries for local and foreign markets. Chiriqui Province in extreme western Panama borders Costa Rica and grows 4,300 ha of citrus that consists
Burkholderia species have different lifestyles establishing mutualist or pathogenic associations with plants and animals. Changes in the ecological behavior of these bacteria may depend on genetic variations in response to niche adaptation. Here, we studied 15 Burkholderia strains isolated from
