Fig. 6: Comparison of the N-C balance systems in Asteraceae and other species.
From: Comparative genomics reveals a unique nitrogen-carbon balance system in Asteraceae

a Canonical N-C balance system in species containing PII. The structure of trimeric PII was downloaded from Protein Data Bank (https://www.ncbi.nlm.nih.gov/Structure/pdb/2O67). b The deduced N-C balance system in Asteraceae lacking PII. The strengthened uptake of N, and N and C assimilation processes are shown in bold red font. The regulation processes were indicated by lines, while the dotted ones represented the biological process that has not been directly confirmed but highly speculative.
