摘要

Fourteen isolates of the entomopathogenic fungus Beauveria bassiana could be introduced as an endophyte into jute plant (Corchorus capsularis) through seed inoculation. Only four endophytic isolates induced the activation of salt stress-tolerant gene pathways in the jute plants that were treated. RNA Sequencing identified 1017 differentially expressed genes between the ‘endophyte colonized plant’ and the ‘untreated plant’. A total of 1117 genes exhibited upregulation, while 279 genes showed downregulation in the treated plant. The expression of salinity stress resistant genes (SLT1, GDSL, KAT3) were significantly up regulated. Furthermore, the analysis revealed the presence of genes encoding transcription factors MYB, bHLH, NAC, bZIP, WRKY, and zinc finger among the 1017 differentially expressed genes.
