Their expression is developmentally regulated, often by their own promoter and regulatory elements, similar to developmental protein coding factors [ 10].
I tested the assumption of size as a proxy for age by regressing size (PC1) against developmental age codes ([ 30], ages 1 to 6) separately for males and females.

Genes related to developmental processes code for the AAA-ATPase (At5g40010) which participates in plastidial transport [ 84], for the CAFFEOYL-COA 3-O-METHYLTRANSFERASE (At1g67980) which catalyses lignin monomer biosynthesis [ 85], and the CATION/H+ EXCHANGER17 (At4g23700) which regulates cation and pH homeostasis [ 86].
Transcripts with decreased detection in this tissue are significantly enriched for genes associated with developmental processes and coding calcium binding proteins.
Sequencing plant genomes along the evolutionary path will be very helpful in elucidating how modifications in expression of key developmental genes and/or coding sequences during evolution are somehow responsible for major trait changes or innovations.
Furthermore, the majority of our predictions is known to play a role during development and is associated with one or more CGIs that are distributed along the miRNA primary transcript, indicating that these ST miRNAs may be subject to the same type of Polycomb-mediated repression seen in protein coding developmental genes.
They are therefore functionally related to a number of key protein coding developmental genes, that form genomic regulatory blocks (GRBs) with arrays of highly conserved non-coding elements (HCNEs) functioning as long-range enhancers that collaboratively regulate the expression of their target genes.
Because the amount and type of parental assistance provided during this task had the potential to be influenced by the child's developmental level, the coding system was devised to isolate and focus on the portions of the child's behavior that were equivalent across the entire age-span and range of ability levels.
Alternatively, divergent transcription might reflect an intrinsic property of promoters of genes coding for developmental regulators.
