Co-expression network analysis and cis-regulatory element enrichment determine putative functions and regulatory mechanisms of grapevine ATL E3 ubiquitin ligases.

ABSTRACT: Arabidopsis thaliana Toxicos en Levadura (ATL) proteins are a subclass of the RING-H2 zinc finger binding E3 ubiquitin ligases. The grapevine (Vitis vinifera) ATL family was recently characterized, revealing 96 members that are likely to be involved in several physiological processes through protein ubiquitination. However, the final targets and biological functions of most ATL E3 ligases are still unknown. We analyzed the co-expression networks among grapevine ATL genes across a set of transcriptomic data related to defense and abiotic stress, combined with a condition-independent dataset. This revealed strong correlations between ATL proteins and diverse signal transduction components and transcriptional regulators, in particular those involved in immunity. An enrichment analysis of cis-
