“Although it is a major freshwater gastropod species, genetic diversity of Bellamya aeruginosa was completely unknown. Eighteen microsatellite loci were isolated and characterized from (AC)(15)-enriched genomic libraries of the freshwater snail B. aeruginosa. Most of the 18 loci were SB-715992 successfully amplified and high polymorphic information content values were found, ranging from 0.244 to 0.792 (mean 0.541). The number of alleles per locus ranged from 5 to 13 (mean 8.8), the expected heterozygosity varied from 0.347 to 0.950 (mean 0.815) and Daporinad concentration the observed heterozygosity varied from 0.087 to 0.782 (mean 0.431). Eight loci showed significant deviation from Hardy-Weinberg equilibrium after Bonferroni’s correction and no significant genotypic linkage disequilibrium was detected between most locus pairs, except for TXH79-TXH97 and TXH113-TXH121. These 18 polymorphic microsatellite loci should be useful for population genetics analysis and species identification of Bellamya.”
“P>The Tic20 protein was identified in pea (Pisum sativum) as a component of the chloroplast protein import apparatus. In Arabidopsis, there are four Tic20 homologues,
termed atTic20-I, atTic20-IV, atTic20-II and atTic20-V, all with predicted topological similarity to the pea protein (psTic20). Analysis of Tic20 sequences from many species indicated that they are phylogenetically unrelated to mitochondrial find more Tim17-22-23 proteins, and that they form two evolutionarily
conserved subgroups [characterized by psTic20/atTic20-I/IV (Group 1) and atTic20-II/V (Group 2)]. Like psTic20, all four Arabidopsis proteins have a predicted transit peptide consistent with targeting to the inner envelope. Envelope localization of each one was confirmed by analysis of YFP fusions. RT-PCR and microarray data revealed that the four genes are expressed throughout development. To assess the functional significance of the genes, T-DNA mutants were identified. Homozygous tic20-I plants had an albino phenotype that correlated with abnormal chloroplast development and reduced levels of chloroplast proteins. However, knockouts for the other three genes were indistinguishable from the wild type. To test for redundancy, double and triple mutants were studied; apart from those involving tic20-I, none was distinguishable from the wild type. The tic20-I tic20-II and tic20-I tic20-V double mutants were albino, like the corresponding tic20-I parent. In contrast, tic20-I tic20-IV double homozygotes could not be identified, due to gametophytic and embryonic lethality. Redundancy between atTic20-I and atTic20-IV was confirmed by complementation analysis.
