Sumario:Bletilla striata (Thunb. ex A. Murray) Rchb. f., a species of the perennial herb Orchidaceae, has potent anti-inflammatory and antiviral biological activities. MADS-box transcription factors play critical roles in the various developmental processes of plants. Although this gene family has been extensively investigated in many species, it has not been analyzed for B. striata. In total, 45 MADS-box genes were identified from B. striata in this study, which were classified into five subfamilies (Mδ, MIKC, Mα, Mβ, and Mγ). Meanwhile, the highly correlated protein domains, motif compositions, and exon–intron structures of BsMADSs were investigated according to local B. striata databases. Chromosome distribution and synteny analyses revealed that segmental duplication and homologous exchange were the main BsMADSs expansion mechanisms. Further, RT-qPCR analysis revealed that BsMADSs had different expression patterns in response to various stress treatments. Our results provide a potential theoretical basis for further investigation of the functions of MADS genes during the growth of B. striata.
