Transcriptome analyses of quinoa leaves revealed critical function of epidermal bladder cells in salt stress acclimation

The ability of some halophytic plants such as Chenopodium quinoa to sequester large quantities salt into epidermal bladder cell (EBC) is considered one the traits conferring their salinity stress resilience. In current study, we used mRNA-seq characterize transcriptome differences between intact and EBC-free leaves from that were treated with 400 mM NaCl for 4 weeks. Employing K-means clustering on differentially expressed genes identified clusters showing distinct expression patterns, indicating significant or without EBCs in response stress. retained most responses normal leaves. However, specific processes increased DNA replication activity failed be induced This correlated reduced many immune response-related multiple phytohormone signaling components. These results revealed play a critical role acclimation provided important candidate further mechanistic studies.
