RESILIENCE STRATEGIES AND PATHWAYS TOWARD ROOT TO CAPSULE FOR SESAME YIELD ENHANCEMENT UNDER WATERLOGGED CONDITION
Climate Adaptation
Sesame oil in your kitchen comes from one of the most flood-sensitive crops on earth, and as monsoon rains grow more erratic, the farmers growing it in South Asia and Africa are losing entire harvests to standing water.
When sesame fields flood, the plants essentially suffocate — their roots can't get the oxygen they need to function. Scientists have been cataloguing the clever tricks some sesame plants use to survive: growing emergency roots, building spongy air channels in existing roots, and ramping up chemical defenses. This review pulls all that knowledge together and points toward using genetic tools and smarter planting techniques — like raised beds and better drainage — to breed sesame varieties that can handle the flooding that climate change is making more common.
Key Findings
Waterlogging causes hypoxia (low oxygen) in sesame roots, severely reducing plant growth and yield, particularly in regions with erratic rainfall and poor drainage infrastructure.
Flood-tolerant sesame plants deploy multiple adaptive mechanisms simultaneously: adventitious root formation, aerenchyma (air-channel tissue) development, antioxidant enzyme activation, and accumulation of protective osmolyte compounds.
Molecular breeding tools — including gene mapping, marker-assisted selection, and gene editing — combined with raised-bed planting and farmer participatory field trials offer a combined pathway to deploy climate-resilient sesame cultivars.

Sesame plants are highly vulnerable to waterlogging, which cuts off oxygen to roots and tanks crop yields. This review synthesizes what's known about how sesame survives flooding and maps out breeding and farming strategies to develop flood-tolerant varieties for climate-stressed growing regions.

Sesame is a plant in the genus Sesamum, also called benne. Numerous wild relatives occur in Africa and a smaller number in India. It is widely naturalized in tropical regions around the world and is cultivated for its edible seeds, which grow in pods. World production in 2024 was 6.7 million tonn...
