Figure Lengend Snippet: Loss and retention of genes on chromosomes among the studied species. L. perrieri was used as the reference genome, and a 1 MB sliding window was used to infer the collinear genes (red) and lost genes (light blue) in each chromosome of each species. Red represents retention, and blue represents loss. From the center, the chromosomes in the circle are from O. barthii , O. brachyantha , O. sativa Jing rice, O. glaberrima , O. meridionalis , O. nivara , O. punctata , O. rufipogon, O. glumaepatula , O. sativa Xian rice, S. bicolor , S. italica , and P. americarum . The orange numbers represent chromosome numbers.

Figure Lengend Snippet: Evolutionary trajectory of grass chromosomes. The process of evolution from the ancestral chromosomes of grasses to those of rice, sorghum, foxtail millet, and pearl millet was reconstructed. Before the GCT, seven ancestral chromosomes (in different colors) were inferred. The duplicated chromosomes during the GCT were then reduced to 12 due to chromosome fusions and DNA exchanges, whose major structures have been well preserved in Oryza plants. The 12 chromosomes were then reduced in each plant under study. Os, Sb, Si, and Pg stand for O. sativa , S. bicolor , S. italica , and P. americarum .

Figure Lengend Snippet: Illustrative scheme of aromatic amino acid metabolism from sugar catabolism in S. cerevisiae . Tryptophan is produced from the precursors phosphoenolpyruvate and D‐erythrose 4‐phosphate, from glycolysis and the pentose phosphate pathway respectively, via the shikimic acid pathway. The last part of the diagram represents the pathway we have constructed for the production of serotonin from tryptophan. The enzymes shown are tryptophan decarboxylase (TDC) from C. sporogenes and tryptamine 5‐hydroxylase (T5H) from O. sativa , represented by their AlphaFold structural models.

Figure Lengend Snippet: Effect of expressing Cs TDC, Os T5H and ARO4 * in BY4743 on serotonin production. Table below the graph list heterologous genes present in the different strains. BS3 overexpresses the Cs TDC and Os T5H genes, BS4 overexpresses Cs TDC, Os T5H and ARO4 *, wild type BY4743 was used as a control. Strains were cultivated for 72 h in SD 80 medium with 300 mg/L of nitrogen in the form of ammonium sulphate and L‐TRP mixture (light blue) or ammonium sulphate exclusively (dark blue). Standard deviations from the values of three biological replicates are represented by error bars. The serotonin titres produced by the different strains and the two media were compared using one‐way ANOVA and Tukey's test for a p ‐value < 0.05. Shared letters indicate no significant difference in serotonin titres.
