Low-phosphate-selected Auxenochlorella protothecoides redirects phosphate to essential pathways while producing more biomass
Fig 5
Scatter plots of gene expression expressed as log2 value showed pronounced variability between A. protothecoides subpopulations during low phosphate natural selection.
Expression was determined from RNA-Seq reads, with 1–3 biological replicate(s), and each individual dot represents a different gene. Genes that were significantly up-regulated are shown on the X-axis in red, and down-regulated genes are shown in blue. A. Comparison of gene expression between wk 2 and 6 (R2 = 0.9309), B. wk 6 and 10 (R2 = 0.8711), C. wk 10 and >14 (R2 = 0.61), D. >14 and >22 wks (R2 = 0.392), and E. 2 and >22 wks (R2 = 0.3166). F. Total number of transcripts (log2 signal >1.00 based on the FDR multiple test correction and adjusted p-value < 0.1) for the wk 2 and >22 comparisons.
