Chen  et al.  (  Nature Genet . 51: 1549–1558; Oct. 2019) sequenced  Ananas comosus  var.  bracteatus  accession CB5, cultivated for its bright pink-to-red colored fruit, and yellow-fleshed  A. comosus  accession F153, reporting an improved F153 reference assembly while annotating  MICRORNA (MIRNA)  loci and gene family expressions relevant to lignin and anthocyanin biosynthesis. An independent article (Xiong  et al.   Sci. Rep . 8: 1947; 2018) reported var.  bracteatus MIRNAs  but not  MIR828 , a negative regulator of anthocyanin and polyphenolics biosynthesis by targeting  MYB  transcription factors associated with UV light- and sugar-signaling in dicots.  MIR828  has been reported in gymnosperms, Amborella (sister to flowering plants), and basal monocot orders Liliales, Asparagales, Zingiberales, Arecales, but not in the Poales, a sister order comprising grasses and ~3,000 species of bromeliads including pineapple. Here I show  MIR828  exists in pineapple and directs post-transcriptional gene silencing of mRNAs encoding MYB family members with inferred function to regulate the conspicuous red fruit trait in var.  bracteatus .   MIR828  plesiomorphy (an ancient basal trait) may shed light on monocot apomorphic fruit development, postulated for 21 monocot families with fleshy fruits as due to homoplasy/convergence driven by tropical climate and/or enticements to vertebrate endozoic seed dispersers.
