aerial - The subset of genes with preferential gene expression in aerial tissues.

seed - The subset of genes with preferential gene expression in seed developmental stages.

underground - The subset of genes with preferential gene expression in underground tissues.

Relationship between exon length, percent GC content and specific tissue groups for three classes of exons: the first exon (first), the internal exons (internal) and last exon (last).
