The Length Distributions of Non-Coding and Coding Sequences in Relation to Gene Expression: A Study on Arabidopsis thaliana

摘要

The availability of complete genomic sequences as well as other gene related databases, such as gene expression datasets, allows for extended exploration of the production of gene products. Using the length distribution data of the coding and non-coding regions of a gene and it corresponding gene expression values the aim was to determine if there was a relationship between these values. Pearson's correlation showed that the coding and 5' UTR lengths are negatively correlated in relation to gene expression intensity, however the 3' UTR length showed positive correlation. This was confirmed by using quantile regression analysis on the data. The results support the role and importance of these length regions in the regulation of gene expression.
