Mutation Pressure and Gene‐Specific Selection Shape Codon Usage Bias in the Chloroplast Genomes of Isoetes, an Ancient Aquatic Vascular Plant Lineage
ABSTRACT Isoetes is one of the most ancient extant vascular plant genera and represents a distinct evolutionary lineage within lycophytes. Its chloroplast genome preserves molecular signatures relevant to early land plant evolution. However, the evolutionary forces shaping codon usage bias (CUB) in Isoetes chloroplast...
