Pseudogenes in Plants: Their Associations with Long Noncoding RNAs and MicroRNAs
Research, The Plant Cell, The Plant Cell: In a NutshellXie et al. applied a multifaceted approach to study plant pseudogenes, combining RNA-seq, comparative genomics, and molecular biology. They conclude that rapid rewiring of psuedogene transcriptional regulatory regions is a major mechanism driving the origin of novel regulatory modules. Plant Cell https://doi.org/10.1105/tpc.18.00601
