  1. a)Membrane-associated include plasma membrane (PM), transmembrane (TM), kinases/receptors/signal transduction, TM transport, porins, and Wall/PM proteins
  2. b)Number of genes and percentages (parentheses) per memory group and function are reported, with a comparison to the percentage of genes found in Arabidopsis thaliana [square brackets]. Only percentages equal or higher than 0.7 are reported, and higher than 1% are rounded to the nearest integer. For the Arabidopsis comparison, 0% means detected but smaller than 0.7%, while ND denotes Not Detected. The specific transcription factor subcategories (AP2/ERF, bZIP, etc.) show percentages based on the overall number of memory genes encoding transcription factors.
