Our previous observation that host plant extracts induce production and secretion of mannitol in the tobacco pathogen Alternaria alternata suggested that, like their animal counterparts, plant pathogenic fungi might produce the reactive oxygen quencher mannitol as a means of suppressing reactive
Apium virus Y (ApVY) has been detected for the first time in New Zealand. In January 2006, leaf mosaic and vein-banding symptoms were observed on cultivated celery (Apium graveolens cv. Tongo) in Wanganui, New Zealand. Symptoms were widespread and seen in several paddocks. Similar symptoms were also
To investigate its potential application as a selectable marker for plant transformation, the mannitol producing, celery mannose-6-phosphate reductase gene (M6PR) was transformed into Arabidopsis and tobacco using Agrobacterium tumefaciens-mediated transformation. Mannose-tolerance assays in
Celery latent virus (CeLV) is an incompletely described plant virus known to be sap and seed transmissible and to possess flexuous filamentous particles measuring about 900 nm in length, suggesting it as a possible member of the family Potyviridae. Here, an Italian isolate of CeLV was transmitted by
Rapid and low-cost methods of detecting mutations and polymorphisms are crucial for genotyping applications including mutagenesis and gene editing. S1 family endonucleases such as T7E1, EndoV and CELI can potentially be used in enzymatic mismatch detection. Among them, CELI has been shown to be
A second mannitol transporter, AgMaT2, was identified in celery (Apium graveolens L. var. dulce), a species that synthesizes and transports mannitol. This transporter was successfully expressed in two different heterologous expression systems: baker's yeast (Saccharomyces cerevisiae) cells and
Salinity is a major limiting factor affecting crops production, survival and distribution worldwide. Engineering dehydration stress tolerance in commercial crops is a trait of economic importance, especially in saline-affected areas. In this work, we are reporting the cloning of the M6PR gene
Human cytochrome P450 (CYP) 2A6 participates in the metabolism of nicotine and precarcinogens, thus the deliberate inhibition of CYP2A6 may reduce cigarette consumption and therefore reduce the risk of developing the types of cancer associated with smoking. The inhibitory effects and mechanisms of
'Candidatus Liberibacter solanacearum' (Lso) is a phloem-limited bacterium that severely affects important Solanaceae and Apiaceae crops, including potato, tomato, pepper, tobacco, carrot and celery. This bacterium is transmitted to solanaceous species by potato psyllid, Bactericera cockerelli, and
Alfalfa mosaic virus (AMV) has a wide host range and is distributed throughout the world. It causes disease in several vegetable crops, including bean, celery, lettuce, pea, pepper, and tomato (1). In Spain, it has been found naturally infecting alfalfa, pepper, and tomato. During the autumn of
The kalanchoe (Kalanchoe blossfeldiana) is an important ornamental species belonging to Crassulaceae. This plant is grown in commercial greenhouses. A survey revealed infections of broomrape, Orobanche aegyptiaca Pers. (syn. Phelipanche aegyptiaca Walp.), on kalanchoe plants in the province of
Italian dandelion (Cichorium intybus L.) is a leafy chicory plant grown as a fresh vegetable in salads. In August 2011, necrotic lesions were observed on leaves of about 20% of the Italian dandelion plants in an experimental field at the Tropical Research and Education Center (TREC) of the
A new disease was observed during the early spring of 2011 and 2012 on coriander (Coriandrum sativum L.) in the Himachal Pradesh state of India. Disease incidence was estimated as 10% in approximately 5 ha. Symptoms were observed as brown leaf spots (1 to 2 × 3 to 5 mm) surrounded by a water soaked
A novel potyvirus was discovered in Angelica lucida L. (wild celery) and A. genuflexa Nutt. (kneeling Angelica) (family Apiaceae) in the Matanuska- Susitna Valley, Alaska. The experimental plant host range of the virus included species in three families: Chenopodiaceae (Chenopodium amaranticolor
Cell lines from selected lepidopteran species were established for the overall purpose of use in baculovirus production. A total of 36 new cell lines from 10 lepidopteran species were generated, including cell lines from a pyralid, the European corn borer, Ostrinia nubilalis, a plutellid, the
