Integrative analysis of transcriptome and metabolome reveal molecular mechanism of tolerance to salt stress in rice.

ABSTRACT:

Background

Salt stress is considered to be one of the major abiotic stresses influencing rice growth and productivity. To improve rice crop productivity in saline soils, it is essential to choose a suitable variety for mitigating salt stress and gain a deep understanding of the underlying mechanisms. The current study explored the salt tolerance mechanism of wild rice 'HD96-1 (salt resistive)' and conventional rice 'IR29 (salt sensitive)' by evaluating morph-physiological, transcriptomic, and metabolomic approaches.

Results

Physiological data indicated that HD96-1 had higher chlorophyll content, higher photosynthetic efficiency, more stable Na⁺/K⁺, less H₂O₂, and lower electrolyte leakage under salt stress compared with IR29. Transcriptomic and metabolo
