Auxin is a type of plant hormone involved in the formation of pegs in cucumber seedlings, which are a gravity-related physical trait, that develop between the plantâs roots and its stem. Understanding how plants sense gravity could enable new genetically modified variants that can grow in microgravity.he investigation examines how plants sense gravity, and how gravity affects plant hormone transportation, plant growth and root development, all of which are important for plant cultivation in space.
