Plant disease risk is strongly influenced by environmental conditions [1]. While some animal hosts may provide their pathogens with a consistent range of body temperatures, plant pathogens are generally much more exposed to the elements. Plant disease will tend to respond to climate change, though a number of interactions take place among host, pathogen, potential vectors. In some cases, the ac...
The phytohormone auxin has been known to be a regulator of plant growth and development ever since its discovery. Recent studies on plant-pathogen interactions identify auxin as a key character in pathogenesis and plant defense. Like plants, diverse pathogens possess the capacity to synthesize indole-3-acetic acid (IAA), the major form of auxin in plants. The emerging knowledge on auxin-signali...
A plant-associated member of the family Enterobacteriaceae, Serratia plymuthica strain AS12 was isolated from rapeseed roots. It is of scientific interest because it promotes plant growth and inhibits plant pathogens. The genome of S. plymuthica AS12 comprises a 5,443,009 bp long circular chromosome, which consists of 4,952 protein-coding genes, 87 tRNA genes and 7 rRNA operons. This genome was...
Several plant pathogenic fungi affect soybean plant health at different growth stages (Table 1). Although infection may occur early, many of these pathogens do not cause apparent symptoms until later growth stages. Frequently seedling health is ignored because plant populations are acceptable and stem and leaves do not express symptoms during early vegetative growth. Phytophthora sojae, Pythium...
Plant pathogenic microbes deliver effector proteins inside host cells to modulate plant defense circuitry and enable parasitic colonization. As genome sequences from plant pathogens become available, genome-wide evolutionary analyses will shed light on how pathogen effector genes evolved and adapted to the cellular environment of their host plants. In the August 2007 issue of Plant Cell, we des...
abstract sclerogenic fungal pathogens, are among the most important diseases of rice plant. sheath blight caused by rhizoctonia solani is one of the economically important diseases that attack a wide range of hosts. stem rot (magnaporthe salvinii) has also been found with different severity in most fields of guilan province. to determine sclerogenic fungal pathogens of rice plant, 141 isolates ...
The significant increase in foodborne outbreaks caused by contaminated fresh produce, such as alfalfa sprouts, lettuce, melons, tomatoes and spinach, during the last 30 years stimulated investigation of the mechanisms of persistence of human pathogens on plants. Emerging evidence suggests that Salmonella enterica and Escherichia coli, which cause the vast majority of fresh produce outbreaks, ar...
Serratia plymuthica are plant-associated, plant beneficial species belonging to the family Enterobacteriaceae. The members of the genus Serratia are ubiquitous in nature and their life style varies from endophytic to free-living. S. plymuthica AS9 is of special interest for its ability to inhibit fungal pathogens of rapeseed and to promote plant growth. The genome of S. plymuthica AS9 comprises...
Pathogens have evolved elaborate mechanisms to invade plant tissues and cause disease. Plants, in turn, respond to pathogen infection by expressing multiple layers of resistance. Once low energy ‘basal’ defences of plant cells have been overcome by pathogens, the plant can employ a more energy costly system of nonself recognition that triggers an ‘acute’ immune response. The survival of plants ...
