Virus-infected plants show strong morphological and physiological alterations. Many physiological processes in chloroplast are affected, including the plastidic isoprenoid biosynthetic pathway [the 2C-methyl-D-erythritol-4-phosphate (MEP) pathway]; indeed, isoprenoid contents have been demonstrated

1-Deoxy-D-xylulose 5-phosphate synthase (DXS) catalyzes the initial step of the plastidial 2C-methyl-D-erythritol-4-phosphate (DOXP-MEP) pathway involved in isoprenoid biosynthesis. In this study, we cloned the complete cDNA of potato DXS gene that was designated StDXS1. StDXS1 cDNA encodes for 719

A new species Trichophyton fischeri was isolated as a contaminant on blood agar plates. This fungus is believed to be a saprophyte. It may be confused with T. rubrum. On peptone dextrose agar plate, the growth is white and velvety to cottony. It occasionally forms furrows. The underside of the

Protected and open field tomato crops are economically important for Portuguese agriculture. In 1983, Pseudomonas syringae pv. tomato (Okabe, 1933) Young, Dye & Wilkie, 1978 was first reported affecting protected crops (3) and then later under open field conditions (1). In the 2009 spring/summer

In 2000 and 2001, a new disease was observed on commercial spinach (Spinacia oleracea) in the Salinas Valley, Monterey County, CA. Initial symptoms were water-soaked, irregularly shaped leaf spots (2 to 3 mm diameter). As the disease developed, spots enlarged to as much as 1 to 2 cm, were

Diffuse knapweed (DK) plants were discovered in Mosier, Wasco County, OR (45.6842°N, 121.4021°W) with crown gall-like symptoms near the soil line. Specimens were collected on 27 July 2004 and sent to the USDA-ARS at Ft. Detrick, MD for identification of disease and pathogen. Pure culture of a

Because production of dry peas (Pisum sativum L.) is increasing in Spain, disease surveys were carried out from 2004 to 2006 in Castilla y Leon, the largest pea-producing region. In May of 2004, a leaf and stem blight caused an estimated 25% loss in yield in pea (cv. Messire) fields in El Cerrato

In the 1995 to 1996 winter vegetable season, a leaf spot disease of cilantro (fresh coriander) (Coriandrum sativum L.) was widespread throughout commercial plantings in the Everglades Agricultural Area south and east of Lake Okeechobee. Symptoms first appeared as water-soaked spots ≤1 mm in

In 2006, symptoms of brown blotch were observed on cultivated Pleurotus eryngii (king oyster mushroom) in Castilla-La Mancha (Spain). Subsequently, between January and May of 2008, brown blotch affected 39.75% of the blocks of substrate cultivated, resulting in a considerable loss of production.

Hypertrophy and hyperplasia resembling crown galls were found on roots of Euphorbia esula/virgata at a single site in east-central Hungary in 2005. E. esula/virgata, known as leafy spurge in North America, is an invasive species causing substantial economic losses to the value of grazing lands in

A new disease was observed during the spring and autumn of 2009 and 2010 on kiwifruit plants (Actinidia deliciosa cv. Hayward) in Rize Province of Turkey. Disease incidence was estimated as 3% in approximately 10 ha. Symptoms were characterized by dark brown spots surrounded by yellow halos on
