预览提示词
A publication-quality comparative genomics figure pairing a phylogenetic tree on the left with an aligned presence/expression heatmap on the right, sharing a common y-axis of 8 species tips. Draw a rooted cladogram with branch lengths and a scale bar (0.05 substitutions/site), leaf labels in italics (Escherichia coli, Salmonella enterica, Bacillus subtilis, Staphylococcus aureus, Pseudomonas aeruginosa, Klebsiella pneumoniae, Mycobacterium tuberculosis, Streptococcus pneumoniae), and bootstrap support values (98, 87, 100, 76) at internal nodes. Color two or three clades distinctly with a small legend. Align each tip to a heatmap row spanning 10 gene columns (recA, gyrB, rpoB, mecA, blaTEM, sodA, katG, ftsZ, dnaK, groEL); use a blue-to-red gradient with a labeled colorbar for log2 expression, plus a faint grid. Clean white background, legible sans-serif labels, tidy spacing, balanced panel proportions.
