Figure 2From: Functional annotation of 19,841 Populus nigra full-length enriched cDNA clonesFlow chart of the functional annotation of PnFL cDNA clones. In total, 19,841 nonredundant PnFL clones were subjected to functional annotation. Parallelogrammatic elements with a left number indicate the results of each adjacent procedure (see Results and discussion). The annotation lists are summarized in aAdditional file 2, bAdditional file 3 and cTable 1.Back to article page
