De novo derivation of proteomes from transcriptomes for transcript and protein identification
Identification of proteins by tandem mass spectrometry requires a database of the proteins that could be in the sample. This is available for model species (e.g. humans) but not for non-model species. Ideally, for a non-model species the sequencing of expressed mRNA would generate a protein database for mass spectrometry based identification, allowing detection of genes and proteins using high throughput sequencing and protein identification technologies. Here we use human cells infected with human adenovirus as a complex and dynamic model to demonstrate this approach is robust. Our Proteomics Informed by Transcriptomics technique identifies >99% of over 3700 distinct proteins identified using traditional analysis reliant on comprehensive human and adenovirus protein lists. This facilitates high throughput acquisition of direct evidence for transcripts and proteins in non-model species. Critically, we show this approach can also be used to highlight genes and proteins undergoing dynamic changes in post transcriptional protein stability

Molecular aspects of somatic-to-embryogenic transition in plants
Somatic embryogenesis (SE) is a model system for understanding the physiological, biochemical, and molecular biological events occurring during plant embryo development. Plant somatic cells have the ability to undergo sustained divisions and give rise to an entire organism. This remarkable feature is called plant cell totipotency. SE is a notable illustration of plant totipotency and involves reprogramming of development in somatic cells toward the embryogenic pathway. Plant growth regularities, especially auxins, are key components as their exogenous application recapitulates the embryogenic potential of the mitotically quiescent somatic cells. It has been observed that there are genetic and also physiological factors that trigger in vitro embryogenesis in various types of plant somatic cells. Analysis of the proteome and transcriptome has led to the identification and characterization of certain genes involved in SE. Most of these genes, however, are upregulated only in the late developmental stages, suggesting that they do not play a direct role in the vegetative-to-embryogenic transition. However, the molecular bases of those triggering factors and the genetic and biochemical mechanisms leading to in vitro embryogenesis are still unknown. Here, we describe the plant factors that participate in the vegetative-to-embryogenic transition and discuss their possible roles in this process
