Overview of the functional classification of the P. nigra ESTs. In total, 10,829 of the 19,841 nonredundant ESTs that comprised the 5' or 3' reads that yielded the lowest E value for each clone were assigned to eukaryotic clusters of KOGs. Designations of functional categories and the proportion of each: A, RNA processing and modification; B, chromatin structure and dynamics; C, energy production and conversion; D, cell cycle control and mitosis; E, amino acid transport and metabolism; F, nucleotide transport and metabolism; G, carbohydrate transport and metabolism; H, coenzyme transport and metabolism; I, lipid transport and metabolism; J, translation, ribosomal structure, and biogenesis; K, transcription; L, replication and repair; M, cell wall/membrane/envelope biogenesis; O, posttranslational modification, protein turnover, and chaperone functions; P, inorganic ion transport and metabolism; Q, secondary metabolite biosynthesis, transport, and catabolism; T, signal transduction; U, intracellular trafficking, secretion, and vesicular transport; V, defense mechanisms; W, extracellular structures; Y, nuclear structure; Z, cytoskeleton; R, general functional prediction only; and S, function unknown.
