Isolation and functional validation of stress tolerant gene and its comparative physio-biochemical analysis with transgenic tobacco plants overexpressing and .

MYB transcription factors are one of the most important mediators for the survival of plants under multiple stress responses. In the present study, , encoding a single R3 repeat MYB DNA binding domain was isolated from stress-tolerant wild relative species of sugarcane . In silico analysis of 948 bp coding mRNA sequence of exhibited the presence of four exons and three introns.

Biochemical characterization and identification of differentially expressed candidate genes in salt stressed sugarcane.

Sugarcane productivity is worldwide subjected to increasing environmental constraints, predominantly to drought and salinity owing to their high magnitude of impact and wide distribution. The present study provides insights into the knowledge of sugarcane responses at germination, tillering and respective recovery stages to high salinity at physio-biochemical and molecular level. Our results indicated that there was a negative relationship between catalase, and peroxidase activity with lipid peroxidation and SOD activity.
