Transcriptome-Based Comparative Analysis of Transcription Factors in Response to NaCl, NaOH, and Na2CO3 Stresses in Roots of Autotetraploid Rice (Oryza sativa L.)

Soil salinity is a severe constraint on crop productivity that triggers plant salt stress response pathways. The responses are controlled by transcriptional regulatory networks enhance tolerance manipulating the expression of transcription factor (TFs)-encoding genes. Identifying TFs associated with contributes to salt-tolerant breeding. In this study, comparative transcriptome analysis was performed investigate global gene entire in diploid and autotetraploid rice different levels, considering NaCl stress, NaOH Na2CO3 stress. A total 54, 54 55 TF families were co-expressed tetraploid roots under three stresses, respectively. Furthermore, we investigated differentially expressed (DE-TFs) based comparisons, statistical indicated DE-TFs derived from types as follows: (53 families, 1356 DE-TFs) > (19 214 (18 152 DE-TFs). These results imply induced more obvious biological than other two stresses. GO KEGG pathway enrichment revealed importance hormone signal transduction MAPK signaling pathways may contribute saline–alkaline rice. This study provides resources valuable for exploring mechanism involved polyploid
