62 Desiccation-Tolerant Plant Species Discovered in Western Ghats

• 21 Jul 2023

Recently, scientists from Agharkar Research Institute (ARI), Pune, discovered 62 Desiccation-Tolerant (DT) Vascular plant species in Western Ghats. These plants have a remarkable ability to withstand extreme dehydration, losing up to 95% of their water content, and revive themselves when water is available again.

Key Points:

• Rich Biodiversity: The study sheds light on the biodiversity and ecology of Western Ghats, providing valuable information for conservation efforts.
• Global Hotspot: Among the 62 species, 16 are Indian endemic, and 12 are exclusive to the Western Ghats, highlighting the region's significance as a global biodiversity hotspot.
• Drought Resistance Potential: Understanding the mechanisms behind DT plants' dehydration tolerance may lead to the development of crops that are more drought-resistant and require less water, contributing to sustainable agriculture.
• Diverse Habitats: The DT species were found not only in rock outcrops but also on tree trunks in partially shaded forests, expanding our understanding of their habitat preferences.
• Potential Agricultural Applications: The DT plants' ability to survive in harsh, arid environments makes them potentially valuable for agriculture, especially in water-scarce regions. They could offer insights for developing drought-resistant crops.
• New Genera Reported: The research reported nine new genera of DT plants, including Tripogon capillatus, a native species found in Southern Arabian Peninsula, India to Myanmar, and the first record of an epiphytic DT angiosperm.
