FIGURE 9.

Overview of seasonal changes in metabolite and lipid abundances in poplar twigs. Seasonal differences in metabolite and lipid abundances in the twig buds/leaves, bark, and wood is summarized for dormancy, spring and summer. Bold and bigger font demonstrated higher abundance of the compound in relation to other season(s). Vice versa smaller letter indicate lower amount of the compound in relation to other season(s). Magenta written compounds relate to the P metabolism, green written compounds relate to the N nutrition while black or gray written compounds refer to the C and S metabolism. Light gray and light green fonts indicated the low abundance of TAG, glycerol, and of protein at this time of the year. Black arrows show the places of phospholipids. Broken lines of protein body, amyloplasts and oleosome in spring indicated their degradation. a, amyloplast; o, oleosome; p, proteine body; AAs, proteinogenic amino acids.
