Transcriptional and post‐transcriptional mechanisms regulating salt tolerance in plants

Abstract

Amid mounting global human population, particularly in the developing world, climate change continues to challenge food security and crop cultivation. Hence, mitigation strategies are needed to sustain and invigorate the crop resources needed for agriculture. Within the broad purview and compliance of sustainable development goals (SDG), it is also a compelling task to improve the way food is produced and, in this context, research advances should provide solutions. Among the different abiotic stresses, soil salinity is a critical threat for sustainable agriculture. Changing climatic scenario and the rising seawater levels have created undue pressure on new, novel strategies for developing plants with salinity tolerance. Soil salinity at ≥4 dS m À1

Mitigating the impact of soil salinity: recent developments and future strategies

“…Salt-tolerant plants are defined as halophytes, and employ effective salt-tolerance mechanisms to avoid salt damage and survive salinity stress (Tester, 2003). Stress tolerance to salinity is a complex phenomenon, involving fine-tuned plant responses to osmotic and oxidative stress such as ionic homeostasis, membrane stabilization and phytohormones production (Kumar et al, 2021). Tolerant plants involve diverse regulatory mechanisms thanks to the reprogramming of the expression of several key genes, which is crucial to restore and re-establish cellular homeostasis during stress and the recovery phase (Kumar et al 2021).…”

Vita et al (2021) compared the transcript profiling of two quinoa genotypes with contrasting salt tolerance, providing insights into the early-stage molecular mechanisms, both at the shoot and root level.…”
