“…Figure 2 shows the functional categories of the identified proteins. The most abundant category is belonging to DNA/RNA metabolism (75), followed by plant growth related proteins (65), hypothetical (29), miscellaneous (28), signalling (27), stress protein (26), lipid metabolism (19), cell protein (19), hormone metabolism (14), development (14), transport (14), secondary metabolism (11), amino acid metabolism (8), C-1 metabolism (9), cell wall proteins (6), metal handling (6), photosynthesis (4), redox (4), major CHO metabolism (3), co-factor and vitamin metabolism (3), tetrapyrrole synthesis (3), minor CHO metabolism (2), mitochondrial electron transport (2), nucleotide metabolism (2) and finally protein related to biodegradation of xenobiotics (1). Only proteins related to C1-metabolsim are selected and their matched peptide sequences are listed in Table 1.…”
