[2]) Dioscorea is a genus of over 600 species of flowering plants in the family Dioscoreaceae, native throughout the tropical and warm temperate regions of the world.
[11] Several species, known as yams, are important agricultural crops in tropical regions, grown for their large tubers.
This behavior is dependent on the species, but these shoots typically move in a clockwise or counterclockwise direction, induced by circadian rhythms.
[15] This tendril can control the amount of tension and squeeze the object to stay attached to it and prevent falling.
Furthermore, Dioscorea is a twiner, this means that the plant undergoes circumnutation which is a helical movement that allows stems to wrap around objects.
[17] In 2009, an experiment was conducted to address the mechanism of force generation in the twining plant, Dioscorea bulbifera.
Authors found that the amount of force being applied to the pole when the vine is twining is due to the stretching of the stipule.
[19] Overall, Dioscorea has a vining mechanism that allows it to obtain nutrients while living under a canopy; it has evolved to do this by seeking out surfaces to climb and latch onto.
The Alangan Tribe of Mangyan in the Island of Mindoro in the Philippines, locally known as Karot/Nami; Uses this type of tuber as an alternative of rice.
