Coexpression network of Paspalum notatum. a Coexpression network of all analyzed transcripts; the more centralized genes shown in light gray are common to all genotypes analyzed with nondifferential expression. Node color denotes the differentially expressed transcripts among the phenotypic classes as follows: purple (2X sex vs. 4X apo), yellow (2X sex vs. 4X sex), and dark green (4X apo vs. 4X sex). Networks of exclusively expressed transcripts in each phenotypic class are highlighted as follows: (b) transcripts specific to sexual diploids (blue); (c) transcripts specific to sexual tetraploids (green); and (d) transcripts specific to apomictic tetraploids (red). Edges denote interaction strength. Circular nodes represent transcripts
