1043859 | Perceptual and Neural Olfactory Similarity in Honeybees | The question of whether or not neural activity patterns recorded in the olfactory centres of the brain correspond to olfactory perceptual measures remains unanswered. To address this question, we studied olfaction in honeybees Apis mellifera using the olfactory conditioning of the proboscis extension response. We condi... | Introduction Stimulus discrimination and generalisation constitute two major abilities exhibited by most living animals. Discrimination allows treating different signals as distinct, while generalisation allows treating different but similar stimuli as equivalents [ 1 , 2 , 3 ]. Similarity along one or several perceptu... | D:\keerthana\PMC001xxxxxx\PMC1043859.xml |
1043860 | Principles of MicroRNA–Target Recognition | MicroRNAs (miRNAs) are short non-coding RNAs that regulate gene expression in plants and animals. Although their biological importance has become clear, how they recognize and regulate target genes remains less well understood. Here, we systematically evaluate the minimal requirements for functional miRNA–target duplex... | Introduction MicroRNAs (miRNAs) are small non-coding RNAs that serve as post-transcriptional regulators of gene expression in plants and animals. They act by binding to complementary sites on target mRNAs to induce cleavage or repression of productive translation (reviewed in [ 1 , 2 , 3 , 4 ]). The importance of miRNA... | D:\keerthana\PMC001xxxxxx\PMC1043860.xml |
1043861 | Seeds of Destruction: Predicting How microRNAs Choose Their Target | null | Compare the gene number of fruitfly (13,000) to human (20,000), and it's pretty clear that complexity emerges not just from gene number but from how those genes are regulated. In recent years, it's become increasingly clear that one class of molecules, called microRNAs (miRNAs), exert significant regulatory control ove... | D:\keerthana\PMC001xxxxxx\PMC1043861.xml |
1043862 | Cracking the Olfactory Code | null | For Proust, a taste of cookie was enough to trigger vivid recollections of his childhood, the first of a long string of reveries that he fashioned into his famous memoir Remembrance of Things Past . For many animals, too, tastes and smells are evocative and play a crucial role in finding food, allowing them to build on... | D:\keerthana\PMC001xxxxxx\PMC1043862.xml |
1044830 | Recombination Difference between Sexes: A Role for Haploid Selection | Why the autosomal recombination rate differs between female and male meiosis in most species has been a genetic enigma since the early study of meiosis. Some hypotheses have been put forward to explain this widespread phenomenon and, up to now, only one fact has emerged clearly: In species in which meiosis is achiasmat... | Introduction Sex differences in recombination were discovered in the first linkage studies on Drosophila [ 1 , 2 ] and Bombyx (Tanaka [1914] in [ 3 ]) almost one century ago. However, this observation remains today largely unexplained despite several attempts. Based on very limited observations (see Table 1 ), especial... | D:\keerthana\PMC001xxxxxx\PMC1044830.xml |
