The advancement in functional genomics, such as DNA microarrays along with the genome availability of important pathogens as well as of human and livestock species has allowed scientists to study the expression of thousands of genes in a single step. In the past decade, DNA arrays have been employed to study infectious processes of pathogens, in diagnostics, and to study host-pathogen interactions. The generation of enormous data sets by microarray experiments also stimulated the growth of a new generation of analytical software. The information provided by microarray experiments has been useful in generating new hypotheses for future research. The concept of DNA array technology has been utilized in the development of novel diagnostic methods. This review highlights the application of microarrays in the field of veterinary research. 相似文献

Rice (Oryza sativa L.) is one of the three major food crops of the world and India is the largest rice growing country accounting for about one-third of the world average under the crop. Rice is being cultivated in Northern India since ca 2000 BC as evident from archaeological studies. A total of 103 traditional varieties of rice collected from interior parts, during the study period. The present study was designed with the aim to document the rice diversity and its socio-economic and cultural importance for local farming communities of Garhwal Himalaya in Central Himalayan Region. For collection of information 324 households from 116 villages in the study area were sampled. The study revealed different agro-eco-niches of the study area, traditional processing pathways, socio-economic and cultural development, diversity available, factors responsible for erosion/replacement of diversity, aesthetic values and specialized food quality of local rice varieties etc. The number of rice varieties grown and available for cultivation in ten valleys of Garhwal Himalaya were documented so as these can be utilized and conserved for research and development in the future. 相似文献

Water probably flowed across ancient Mars, but whether it ever exists as a liquid on the surface today remains debatable. Recurring slope lineae (RSL) are narrow (0.5 to 5 meters), relatively dark markings on steep (25° to 40°) slopes; repeat images from the Mars Reconnaissance Orbiter High Resolution Imaging Science Experiment show them to appear and incrementally grow during warm seasons and fade in cold seasons. They extend downslope from bedrock outcrops, often associated with small channels, and hundreds of them form in some rare locations. RSL appear and lengthen in the late southern spring and summer from 48°S to 32°S latitudes favoring equator-facing slopes, which are times and places with peak surface temperatures from ~250 to 300 kelvin. Liquid brines near the surface might explain this activity, but the exact mechanism and source of water are not understood. 相似文献

Bamboo shoots can be harvested at different ages but the data on the changes in nutritional composition with age are scanty. We standardized harvesting age of bamboo shoots in central India to obtain best quality produce with respect to nutritional composition. The shoots harvested on different days (2 20 days after emergence from ground) were analyzed for their nutritional (dietary fibres, carbohydrates, proteins, total phenols, ascorbic acid, sodium, potassium, phosphorus, calcium, magnesium and phenolic acids) and anti nutritional (cyanogen) constituents. A significant variation (at p≤0.5) was observed in the nutritional composition of shoots of Dendrocalamus asper, D. strictus and Bambusa tulda harvested at different days. An overall decrease was observed in proteins and total phenols while dietary fibres and carbohydrates increased with ages. Significant variation (at p≤0.5) was also observed in phenolic acids while minerals did not vary significantly. Results revealed that the optimum harvesting age for D. asper, D. strictus and B. tulda was on 10 14 days, 6 10 days and 10 16 days (after emergence from the ground) respectively. These results can be used to obtain quality bamboo shoots. 相似文献
