A paper in this supplement [19] describes a recent development effort for GO terms, both general and specific, that describe processes involved https://www.selleckchem.com/products/pd-0332991-palbociclib-isethionate.html in the interactions between eukaryotic pathogens and their hosts. In the GO, the more general terms usually describe processes that are shared across diverse organisms, while more specific terms are often

created to describe organism-specific processes. For example one of the child terms of “”GO:0044406 adhesion to host”" is “”GO:0052001 type IV pili-dependent localized adherence to host”", a term relevant to bacterial symbionts. More recently added sibling terms to GO:0052001 include ones describing processes associated with adhesion of filamentous organisms to their host: “”GO:0075001 adhesion of symbiont infection structure to host”" and “”GO:0075004 adhesion of symbiont spore to host”" ([19] this supplement). Since the focus of PAMGO was primarily on microbial pathogens, initial term sets were generated to annotate genes in the microbe that are involved in interactions with the host, e.g. “”GO:0044405 recognition of host”". However,

it quickly became obvious that reciprocal terms that describe the interactions from LDC000067 the perspective of the host would also be required to meet all annotation needs (e.g. “”GO:0051855 recognition of symbiont”" Therefore, parallel sets of terms have been constructed to describe processes in the microbe as well as processes in the host that are involved in the interactions. In addition, terms were included to describe symbiotic relationships where neither organism could be clearly identified as “”host”" versus “”symbiont.”" Thus, under the GO term “”GO:0044419 interspecies interaction between organisms”", there are child

terms to accommodate symbiont genes that affect the host under “”GO:0051701 interaction with host”" and parallel terms appropriate for host genes under “”GO:0051702 interaction with symbiont”" (Figure 1). To learn more about these terms, including their definitions, CBL0137 chemical structure synonyms, child terms, and genes annotated using them, see [20] and search using the term or a keyword within the term. Annotation of selected microbial genomes with new and existing GO terms The members of the PAMGO consortium have been working on annotating the genomes of the bacteria Pseudomonas Sulfite dehydrogenase syringae pv tomato DC3000, Dickeya dadantii (Erwinia chrysanthemii) 3937, and Agrobacteriun tumefaciens; the fungus Magnaporthe oryzae (M. grisea); oomycete species. There are currently over 29,000 GO annotations as a result of the PAMGO project. The annotations can be viewed at [21]. As an example, Meng et al., [22] in this supplement report a comprehensive GO annotation of the rice pathogen Magnaporthe oryzae. In this paper, annotations were based on information from published literature as well as sequence-based analyses.
