pigeonpea (cajanus cajan (l) millsp.) is a drought tolerant legume widely grown in the arid and semi-arid tropics of the world which possesses a deep and extensive root system that succors a number of important physiological and metabolic functions to cope with drought. application of available functional genomics approaches to improve productivity under water deficit requires a better understa...
NCREASING attention is being focused on the use of Drosophila as a I convenient organism for investigating such fundamental problems as the formation of new species and interspecific sterility. Studies of the hybrid from the cross D. melarzogasterXD. simulans by PATAU (I935), and by HORTON (1939), and D. pseudoobscuraXD. miranda by DOBZHANSKY and TAN (1936), as well as studies of the hybrids fr...
Although environmental regulatory stringency has been invoked as one of the most important factors driving the transfer of environmentally sound technologies (ESTs), surprisingly few studies have explored its influence. Employing a recently-assembled dataset of automobile emission standards, and corresponding data on non-resident patent filing of automotive ESTs in 55 countries between 1992 and...
Expressed Sequence Tag (EST) analysis has pioneered genome-wide gene discovery and expression profiling. In order to establish a gene expression index in the rice cultivar indica, we sequenced and analyzed 86,136 ESTs from nine rice cDNA libraries from the super hybrid cultivar LYP9 and its parental cultivars. We assembled these ESTs into 13,232 contigs and leave 8,976 singletons. Overall, 7,49...
Multiple small-scale transcriptome studies have been undertaken for various members of the Penaeidae. Penaeid shrimp are important both as members of diverse ecosystems around the world and for their importance as commercial commodities. Of the many shrimps, the most important from this family is the Pacific whiteleg shrimp, Litopenaeus vannamei, as it is the primary shrimp used in worldwide aq...
The complex hexaploid wheat genome offers many challenges for genomics research. Expressed sequence tags facilitate the analysis of gene-coding regions and provide a rich source of molecular markers for mapping and comparison with model organisms. The objectives of this study were to construct a high-density EST chromosome bin map of wheat homoeologous group 2 chromosomes to determine the distr...
Expressed sequence tags (ESTs) are partial cDNA sequences read from both ends of random expressed gene fragments used for discovering new genes. DNA libraries from four different developmental stages of Schistosoma mansoni used in this study generated 141 ESTs representing about 2.5% of S. mansoni sequences in dbEST. Sequencing was done by the dideoxy chain termination method. The sequences wer...
Whither, or wither, empirically supported therapies? Increasingly rigorous research in behavioral therapies has yielded a large number of effective therapies, but comparatively little work, demonstrating that integrating empirically supported therapies (ESTs) into standard practice results in meaningful improvements in patient outcomes. Methodology and strategies for evaluating ESTs and their e...
The expressed sequence tag (EST) is an instrument of gene discovery. When available in large numbers, ESTs may be used to estimate gene expression. We analyzed gene expression by EST sampling, using the KOG database, which includes 24,154 proteins from Arabidopsis thaliana (Ath), 17,101 from Caenorhabditis elegans (Cel), 10,517 from Drosophila melanogaster (Dme), and 26,324 from Homo sapiens (H...
The US Wheat Genome Project, funded by the National Science Foundation, developed the first large public Triticeae expressed sequence tag (EST) resource. Altogether, 116,272 ESTs were produced, comprising 100,674 5' ESTs and 15 598 3' ESTs. These ESTs were derived from 42 cDNA libraries, which were created from hexaploid bread wheat (Triticum aestivum L.) and its close relatives, including dipl...
