Microbiology of flooded rice paddies FEMS Microbiology

1 Introduction. Rice is the world's most important agronomic plant, with 143 million ha under cultivation globally. In about 75% of this land rice grows under flooded conditions,and such anoxic soil conditions lead to the emission of CH 4.This compound has a high potential for absorbing infrared light and therefore is one of the major greenhouse gases [2, 3].

Disease- and pest- resistant rice International Rice

Blast is considered a major disease of rice because of its wide distribution and extent of destruction under favorable conditions. Although blast is capable of causing very severe losses of up to 100%, little information exists on the extent and intensity of actual losses in farmers' fields. Losses of 5-10%, 8%,and 14% were recorded in India (1960-1961), Korea (mid-1970s), and in China (1980

Plant-mediated transport is the primary mechanism for the emission of methane from rice paddies, with as much as 90% of CH 4 transported to the atmosphere through the aerenchymal system of the rice plants (Cicerone & Shetter, 1981; Holzapfel-Pschorn and Seiler, 1986; Schütz et al., 1989). The rice aerenchymal system not only transports methane from the flooded rice to the atmosphere but also
