Literature-based GO annotation More than 400 research articles were read, and 71 genes with gene knockout mutations and with accession numbers and sequences deposited in public databases such as NCBI were manually annotated using GO terms, including newly developed Plant-Associated Microbe Gene Ontology (PAMGO) terms. Gene products were annotated with GO terms relevant to their biological functions. For example, 6 genes were

annotated with GO:0000187 (“”activation of MAPK activity”"), https://www.selleckchem.com/products/poziotinib-hm781-36b.html 5 genes with GO:0075053 (“”selleck chemical formation of symbiont penetration peg for entry into host”"), 14 genes with GO:0044409 (“”entry into host”"), 8 genes with GO:0044412 (“”growth or development of symbiont within host”"), and 43 genes with GO:0009405 (“”pathogenesis”"). The evidence code Alvocidib price IMP (inferred from Mutant Phenotype) was assigned to these annotations since gene-knockout mutants were generated

in order to determine functions of these genes. A total of 210 genes were annotated on the basis of published microarray studies [3]. Again, gene products were annotated with GO terms, including PAMGO terms, relevant to their biological functions. For example, 67 genes were annotated with GO:0044271 (“”nitrogen compound biosynthetic process”"), 27 genes with GO:0075005 (“”spore germination on or near host”"), 26 genes with GO:0075035 (“”maturation of appressorium on or near host”"), and 114 genes with GO:0075016 (“”appressorium formation on or near host”"). The evidence code IEP (Inferred from expression Pattern) was assigned to these annotations on the basis that the genes were up-regulated by at least 10-fold in very association with the particular biological process.

A further 2,433 genes were annotated on the basis of published Massively Parallel Signature Sequencing (MPSS) studies [4], including 1,041 genes annotated with GO:0043581 (“”mycelium development”"), and 1,392 genes annotated with GO:0075016 (“”appressorium formation on or near host”"). The evidence code IEP was also assigned to these annotations since the genes were up-regulated only during a certain biological process, such as mycelium formation, and the fold change was equal to or greater than 10. On the basis of whole genome T-DNA insertion mutation data [5], 120 genes were annotated with relevant GO terms and PAMGO terms. For instance, 43 genes were annotated with GO:0030437 (“”ascospore formation”"), 14 genes with GO:0009847 (“”spore germination”"), 64 genes with GO:0075016 (“”appressorium formation on or near host”"), and 106 genes with GO:0009405 (“”pathogenesis”"). An evidence code IMP (inferred from mutant phenotype) was assigned to these annotations. In total, 2,810 proteins were annotated based on experimental data from published peer-reviewed literature. Of these, 1,673 proteins were annotated with terms created by the PAMGO consortium to describe interactions between symbionts and their hosts.
