Physiological and gene expression response mechanisms of dehydration process in Cinnamomum cassia (L.) J. Presl seeds.
Background: A critical factor in the storability of recalcitrant seeds is their moisture content (MC), but its effect on the viability of Cinnamomum cassia (L.) J. Presl (C. cassia) seeds is not fully understood.
Methods and results: Measured the germination rate, starch and soluble sugar content, and transcriptome of 8 seed samples with different MC obtained by low-temperature drying method. It was found that the germination rate was significantly negatively correlated with MC. The lethal MC was around 15.6%. During the dehydration process, there was a significant increase in the content of soluble sugars and starch. Transcriptome analysis was performed on CK, W3, W6 showed a total of 62.78 Gb of clean data. Among the 30,228 Unigenes, 28,195 were successfully annotated. In the three comparative groups (CK and W3, CK and W6, W3 and W6), 6,842, 7,640, and 11,628 differentially expressed genes (DEGs) were obtained, respectively. These DEGs were found to be involved in a variety of metabolic pathways, including carbon metabolism, amino acid biosynthesis, starch and sucrose metabolism, glycolysis/gluconeogenesis, and nucleotide and amino sugar metabolism. A total of 1,416 common genes were identified among all three comparison groups. Furthermore, among all the DEGs, a total of 71 transcription factor families were identified, with the C2H2 transcription factor family having the highest number of genes.
Conclusions: This ground-breaking study sheds light on the physiological response and gene expression profiles of C. cassia seeds after undergoing dehydration treatment, which will provide valuable insights for further research and understanding of this process.
