Albino plants lacking photosynthetic pigments are ideal materials for studying photosynthesis. In this study, albino Artocarpus heterophyllus seedlings (AAS) were found during the preliminary investigation. AAS have larger leaves, longer survival time and stable phenotypic traits, so it is a rare woody plant albino material. The expression of photosynthesis-related genes were analyzed through transcriptome sequencing technology and found that the expression of many genes in photosynthetic pigment synthesis, photosynthesis-antenna protein, photoreaction and carbon fixation reaction pathways were down-regulated in AAS leaf, also the expression of genes encoding heat shock protein 70 (HSP70), heat shock protein 90 (HSP90) and HSP70-HSP90-organizing protein 3 (HOP3), which are considered to be key regulators in the plastid-nuclear signaling pathway, were up-regulated. This study discussed the cause of AAS from the synthesis pathway of photosynthetic pigment, and also discussed the expression of photosynthesis-related genes from the aspect of plastid-nuclear signal, which can provide reference for the research of this retrograde signaling pathway.
