摘要： Pepper (Capsicum annuum L.) fruit development is a complex and genetically programmed process. In this study, we conducted integrative analysis of transcriptome and proteome profiles during pepper fruit development. A total of 23 349 transcripts and 5455 protein groups were identified in four fruit developmental stages of two pepper varieties. The numbers of transcripts and proteins identified were decreased gradually across fruit development, and the most significant changes in transcript and protein levels happened from the mature green (MG) to breaker (Br) stages. Poor correlation between differentially expressed transcript and differentially expressed protein profiles was observed during pepper fruit development. We then analyzed expression profiles of transcripts and proteins involved in cell wall metabolism, and capsanthin, tocopherol, and ascorbate biosynthetic pathways during fruit development, and identified key regulatory proteins in these pathways. We presented a dynamic picture of pepper fruit development via comprehensive analysis of transcriptome and proteome profiles at different fruit developmental stages and in different varieties, revealing the temporal specificity of key protein expression. Our report provides insight into the transcription and translation dynamics of pepper fruit development and a reference for other nonclimacteric species.
