Research from National Institutes of Health provides new data about RNA research
2007 NOV 21 -- According to a study from the United States, "The salivary transcriptome of the seed-feeding hemipteran, Oncopeltus fasciatus (milkweed bug), is described following assembly of 1025 expressed sequence tags (ESTs) into 305 clusters of related sequences. Inspection of these sequences reveals abundance of low complexity, putative secreted products rich in the amino acids (aa) glycine, serine or threonine, which might function as silk or mucins and assist food canal lubrication and sealing of the feeding site around the mouthparts." "Several protease inhibitors were found, including abundant expression of cystatin transcripts that may inhibit cysteine proteases common in seeds that might injure the insect or induce plant apoptosis. Serine proteases and lipases are described that might assist digestion and liquefaction of seed proteins and oils. Finally, several novel putative proteins are described with no known function that might affect plant physiology or act as antimicrobials," wrote I.M.B. Francischetti and colleagues, National Institutes of Health. The researchers concluded: "Published by Elsevier Ltd." Francischetti and colleagues published the results of their research in Insect Biochemistry and Molecular Biology (An insight into the sialotranscriptome of the seed-feeding bug, Oncopeltus fasciatus. Insect Biochemistry and Molecular Biology, 2007;37(9):903-910). For additional information, contact J.M.C.
