MicroRNA (miRNA) is one class of newly identified, small, non-coding RNAs that play versatile and important roles in post-transcriptional gene regulation. All miRNAs have similar secondary hairpin structures; many of these are evolutionarily conserved. This suggests a powerful approach to predict the existence of new miRNA orthologs or homologs in other(More)
Seventy-five previously known plant microRNAs (miRNAs) were classified into 14 families according to their gene sequence identity. A total of 18,694 plant expressed sequence tags (EST) were found in the GenBank EST databases by comparing all previously known Arabidopsis miRNAs to Genbank plant EST databases with BLAST algorithms. After removing the EST(More)
MicroRNAs (miRNAs) represent a newly identified class of non-protein-coding approximately 20nt small RNAs which play important roles in multiple biological processes by degrading targeted mRNAs or repressing mRNA translation. After searching a genomic survey sequence database using homologs and secondary structures, we found 188 maize miRNAs belonging to 29(More)
MicroRNAs (miRNAs) are an abundant new class of non-coding approximately 20-24 nt small RNAs. To date, 872 miRNAs, belonging to 42 families, have been identified in 71 plant species by genetic screening, direct cloning after isolation of small RNAs, computational strategy, and expressed sequence tag (EST) analysis. Many plant miRNAs are evolutionarily(More)
Perchlorate (CLO4-) occurrence in groundwater has previously been linked to industrial releases and the historic use of Chilean nitrate fertilizers. However, recently a number of occurrences have been identified for which there is no obvious anthropogenic source. Groundwater from an area of 155,000 km2 in 56 counties in northwest Texas and eastern New(More)
No study has been performed on identifying microRNAs (miRNAs) and their targets in cotton although cotton is one of the most important fiber and economic crops around the world. In this study, we found 30 potential cotton miRNAs using a comparative genomic approach based on genomic survey sequence analysis and miRNA secondary structure. These cotton miRNAs(More)
One of the most important advances in biology in recent years may be the discovery of RNAs that can regulate gene expression. As one kind of such functional noncoding RNAs, microRNAs (miRNAs) form a class of endogenous 19-23-nucleotide RNAs that can have important regulatory roles in animals and plants by targeting transcripts for cleavage or translational(More)
Previous papers have postulated that traditional schemes for the management of replicated data are doomed to failure in practice due to a quartic (or worse) explosion in the probability of deadlocks. In this paper, we present results of a simulation study for three recently introduced protocols that guarantee global serializability and transaction atomicity(More)
The accumulation of perchlorate in vegetation is becoming a concern, with increasing numbers of sites reporting the presence of perchlorate in groundwater and surface water. This study investigated potential perchlorate uptake and distribution by a variety of forage and edible crops in both the laboratory and the field. Perchlorate concentrations in soybean(More)
Metastasizing prostate tumor cells invade along nerves innervating the encapsulated human prostate gland in a process known as perineural invasion. The extracellular matrix laminin class of proteins line the neural route and tumor cells escaping from the gland express the laminin binding integrin alpha6beta1 as a prominent cell surface receptor. Integrin(More)
