Coleoptile elongation - characteristics determining the ability of rice anaerobic germination tolerance Nghi Khac Nhu Abstract Flooding or submergence is one of the natural calamities which a ects the growth and development of rice especially at the germination stage. Rice is the only crop in the cereal group capable of germinating in submerged conditions. e rice anaerobic germination tolerance is characterized by the capacity of rice coleoptile elongation underwater. Over the last several decades many great studies have been conducted to elucidate the mechanism controlling this characteristic. TPP7 gene has been found to play an important role in the anaerobic germination of rice variety Khao Hlan On. Besides the role of some hormones such as Auxin related to elongation ability of rice coleoptile has also been reported. Because of labor shortage for rice production in the Mekong Delta the farming method has changed almost entirely from transplanted rice to direct sown rice dry sowing underground sowing . Studying and utilizing the rice varieties with the ability of rice anaerobic germination tolerance is extremely important. In this review we documented the latest reports on the ability of anaerobic coleoptile elongation of rice and the mechanisms behind this trait as well
