Duckweed Genome GC bias assessment

Summary: Duckweed's CDS sequences are GC biased, while the rest of the non-CDS genome is AT biased.

Screen shot of a region of the duckweed genome. Background is colored based on underlying GC content such that GC rich regions are green and AT rich regions are white. Gene models are composite colored arrows drawn above and below the dashed line in the center of the image. Green regions of gene models are CDS regions. Note that CDS regions correspond to an elevate GC content in genomic sequence.
