摘要: The Arabidopsis vascular system is composed of xylem and phloem, which form a well-defined collateral pattern in bundles. Xylary element fibers develop secondary cell walls (SCWs) that provide mechanical strength to support plant growth transport water minerals all above ground organs. SCWs also constitute the majority terrestrial biomass for biofuel production. biosynthesis are known be under transcriptional regulation. Transcription factors, such as NAC (NAM, ATAF1/2 CUC2) MYB domain proteins, serve master regulators SCW development. Recent studies indicated Class III homeodomain leucine zipper transcription factors (HD-ZIP TFs) microRNA 165/166 (miR165/166) may play important roles formation. Here we discuss diverse functions miR165/166 HD-ZIPIII development their interaction with regulatory pathways biosynthesis.
