Genome-wide profiling of alternative splicing genes in hybrid poplar (P.alba×P.glandulosa cv.84K) leaves
Fig 3
Association between AS events and each factor in the poplar leaves.
All the transcribed genes in the poplar leaves were classified into three groups according to AS frequency in each gene as high AS genes (>5 AS events/gene), low AS genes (1–4 AS events/gene), and non-AS genes. A: Intron length, B: Exon length, C: Exon number, D: GC content, E: Expression level. The different letters indicate significant differences at the level of P < 0.05. The bars indicate SE.
