Soilless culture, known as hydroponics, offers an alternative way to plant growers who faced soil and waterrelated problems such as soilborne pathogens and pests, soil and water salinity, chemical residues, nutrient deficiency and water shortage in soil. Since hydroponic systems are designed to recirculate nutrient solution in closed devices, plants in these systems can be exposed to the risk ...

A novel insertion site inside the potyvirus P1 cistron allows expression of heterologous proteins and suggests some P1 functions.
Rajamaki,-M-L et al. 
The P1 cistron encodes the first and most variable part of the polyprotein of potyviruses. A site tolerant to a pentapeptide insertion at the N-terminus of Potato virus A P1 (Genome Res. 12, 584-594) was used to express heterologous proteins (insertions up to 783 nucleotides) with or without flanking new proteolytic sites. Aequorea victoria green fluorescent protein (GFP) accumulated to high l ...

Downy mildew caused by Peronosclerospora sorghi is a major disease of sweet corns in Thailand. Reactions of 29 sweet corn varieties to downy mildew were examined at farmer's field, Uthaithani province during the early rainy season of 2010. A randomized complete block design with 3 replicates was deployed. Spore suspension at a concentration of 5*10**(4) spores/cc was used. The results showed t ...

A total of 13 actinomycete strains were isolated from mangrove sediment in which 5 actinomycete strains showed potential ntibacterial activity against 5 fish pathogens and 8 human pathogens.Actinomycetes viz., ACT-1, ACT-4, ACT-9, ACT-10 and ACT-12 were showed broad spectrum of sensitivity against all pathogens. The minimum MIC value of 10 μg.ml-1 was recorded with ACT-1 against the fish patho ...

Himachal Pradesh has vast water resources that comprise of rivers, rivulets, reservoirs, irrigation channels adn village ponds. The fish fauna of the state is also distinct, having various genera and species in the aquatic habbitat. Intensive fish production, however, is usually accompanied by increased disease problems as several physical and environmental stresses are predisposing them to in ...

Brichkova, G.G. et al. 
Rhamnolipids by Pseudomonas aeruginosa have been found to exhibit both antimicrobial and antifungal activities. The application of rhamnolipid suspension in planta suppressed diseases caused by pathogen infection. Thus, transgenic plants with rhamnolopid biosynthesis genes have been created. It was shown that the introduction of the rh1B gene provided plants with the tolerance to some pathogen ...

Plant disease specimen samples caused by fungal pathogens were collected and brought to the laboratory at the Department of Plant Pathology, Faculty of Agriculture, Kasetsart University,Bangkhen campus,Thailand. The specimen samples were recorded for disease symptoms with a flat bed scanner. A closed-up symptom of the disease tissues was then, taken for photomicrographs under a stereo zoomed m ...
