To overview the gene content of important pathogen Phytophthora infestans, large-scale cDNA and genomic sequencing was performed. A set 75,757 high-quality expressed sequence tags (ESTs) from P. infestans obtained 20 libraries representing a broad range growth conditions, stress responses, developmental stages. These included infestans-potato -tomato interactions, which 963 ESTs were identified. complement ESTs, onefold coveragethe genome regions coding potential unigene 18,256 sequences...
Phosphorus, a limited resource, is also an environmental pollutant that should be removed from wastewater and ideally reused. A pilot-scale facility was set up used to precipitate recover phosphorus wastewater. The return activated sludge in hydrolysis tank flocculated separated the solid material returned tank; flocculation process did not harm microorganisms. Phosphate reject water precipitated with different calcium salts phosphorus-containing recovered. consisted mainly of phosphate...
Development of reproductive tissue and control cell division are common challenges to all sexually reproducing eukaryotes. The Arabidopsis thaliana TSO1 gene is involved in both these processes. Mild tso1 mutant alleles influence only ovule development, whereas strong have an effect on floral tissues cause defects. mutants described so far carry point mutations a conserved cysteine-rich domain, the CRC but reason for range phenotypes observed poorly understood. In present study,...
Iron is an important micronutrient for all living organisms. Almost 25% of the world population affected by iron deficiency, a leading cause anemia. In plants, deficiency leads to chlorosis and reduced yield. Both animals plants may suffer from when their diet or environment lacks bioavailable iron. A sustainable way reduce malnutrition in humans develop staple crops with increased content Knowledge where how accumulates seeds crop will increase understanding plant metabolism assist...
To establish a reliable and rapid protocol to simultaneously obtain high quality DNA from an infected host plant the infecting pathogen. develop accurate sensitive low-cost assay for quantification in planta monitoring of Phytophthora infestans growth.In this study, we describe SYBR Green-based quantitative real-time PCR (qPCR) method P. infestans. The is based on simultaneous plant-pathogen purification followed by qPCR which relative pathogen performed. Besides assuring quantification, use...
Nodulin genes are specifically expressed in the nitrogen-fixing root nodules. We have identified a novel type of DNA-binding protein (CPP1) interacting with promoter soybean leghemoglobin gene Gmlbc3 . The domain CPP1 contains two similar Cys-rich domains 9 and 10 Cys, respectively. Genes encoding been Arabidopsis thaliana, Caenorhabditis elegans, mouse, human. also some homology to region present polycomb proteins. cpp1 is induced late nodule development expression confined distal part...
Summary Eight genes that are upregulated during sexual development in the heterothallic oomycete, Phytophthora infestans , were identified by suppression subtractive hybridization. Two showed very low but detectable expression vegetative hyphae and became induced about 40‐ to > 100‐fold early mating, before gametangial initials appeared. The remaining six loci not until later coincident with formation of gametangia oospores, induction levels ranging from 60‐ 100‐fold. Five single copy,...
Model legumes such as Lotus japonicus have contributed significantly to the understanding of symbiotic nitrogen fixation. This insight is mainly a result forward genetic screens followed by map-based cloning identify causal alleles. The L. ecotype 'Gifu' was used common parent for inter-accession crosses produce F2 mapping populations either with other ecotypes, MG-20 and Funakura, or related species filicaulis. These all been studies but segregation distortion, suppression recombination,...
During the past decade, legume Lotus japonicus has emerged as an important model system for study of symbiotic nitrogen fixation. Controlled expression genes involved in symbiosis from inducible promoter at specific time points would be a valuable tool investigating gene function L. japonicus. We have attempted to putative transcription factors LjNDX and LjCPP1 by GVG system. This showed that itself causes growth disturbances Shoot internode elongation root pericycle cell division are...
ABSTRACT A gene from Phytophthora infestans that was previously identified as being induced during the development of sexual spores also found to be active asexual sporulation. The gene, M90 , expressed a 3.1-kb primary transcript containing two introns and predicted encode member Puf family translational regulators. protein showed up 51% amino acid identity other proteins within its 353-amino-acid RNA-binding domain. Little similarity extended beyond this region, noted for members family....
The defence responses of potato against Phytophthora infestans were studied using the highly resistant Sarpo Mira cultivar. effects plant integrity, meristems, and roots on hypersensitive response (HR), resistance, regulation PR genes analysed. shoots grafted with susceptible Bintje cultivar as well non-grafted different parts plants inoculated P. infestans. progress infection number HR lesions monitored, was compared in detached attached leaves. Additionally, antimicrobial activity extracts...
This study compares the distribution and concentrations of micro- macronutrients in different bean cultivars with aim optimizing biofortification, a sustainable approach towards improving dietary quality. Micro-PIXE was used to reveal Fe, Zn, Mn, Ca, P, S seeds common beans (Phaseolus vulgaris) runner coccineus). Average elements tissues were obtained using ICP-AES. The highest Zn studied found embryonic axis, but an increased concentration this element also detected provascular bundles...
Filtration is an effective method for removing particles larger than 10–15 µm in swimming pool water. However, the removal of smaller poses a significant challenge. Tests were conducted to improve filter's performance. These tests included choice filter cloth, long-term filtration operation, pre-coating with aids (Arbocel and Harbolite). As expected, cloth affects particle rejection, but other strategies can be employed process. During rejection continuously improved all cloths, after 30...
