Fig. 4From: Systematic analysis of the basic/helix-loop-helix (bHLH) transcription factor family in pummelo (Citrus grandis) and identification of the key members involved in the response to iron deficiencyChromosomal localizations and gene duplications of CgbHLH genes. The green and red colors represent tandem duplicated and segmental duplicated genes, respectively. The CgbHLH genes followed by the same number (highlighted with blue circles) are collinear genesBack to article page
