Functional categorization of GO terms. Multilevel pie chart with the lowest node per branch from the annotations graph. GO terms were distributed into: (A) biological process, (B) cellular component, (C) molecular function. A: response to stress, catabolic processes and carbohydrate metabolic processes were the most common. B: cytoplasmic membrane-bounded vesicles, plasma membrane and plastids were the most common. C: Nutrient reservoir activity and nucleotide binding were most common.
