MsaH2A.W is identified response to salt tolerance in Miscanthus sacchariflorus
GCB Bioenergy, Volume 15, Issue 8, Page 1058-1073, August 2023., 2023 To study the underlying genetic basis of Miscanthus adaptation to salt stress, the transcriptome variations of Miscanthus sinensis, Miscanthus sacchariflorus and their hybrid were analysed using RNA‐seq technology under salt treatment. According to the expression pattern of known salt‐tolerant genes, a histone variant gene MsaH2AW of M.
