Grapevine Subtilase Family: Update on New Sequences and Nomenclature Proposal

Abstract

In grapevine, serine peptidases from the subtilase family were recently associated to Plasmopara viticola resistance. This family in grapevine, first characterized in 2014, was re-analyzed last year and 82 subtilase genes were identified. However, in November of 2016, the National Center for Biotechnology Information database (NCBI) made a new public release of the grapevine genome annotation based on new sequencing data and better prediction algorithms. As a consequence, some gene annotations and lengths changed. Here we present an update to the grapevine subtilase gene family sequences (SBT), namely sequence identifiers, bioinformatic predictions and recommend a nomenclature for the grapevine SBT genes. Our results show that grapevine subtilase gene family is now constituted by 87 subtilase genes encoding for 109 subtilase proteins and, despite the reported alterations, expression data on subtilases associated to grapevine resistance to P. viticola pathosystem did not suffer any alteration.
