Plants have evolved intracellular immune receptors to detect pathogen proteins known as effectors. How these immune receptors detect effectors remains poorly understood. Here we describe the structural basis for direct recognition of AVR-Pik, an effector from the rice blast pathogen, by the rice intracellular NLR immune receptor Pik. AVR-PikD binds a dimer of the Pikp-1 HMA integrated domain wi...

Ischaemum rugosum is a competitive weed in direct-seeded rice systems. Developing integrated weed management strategies that promote the suppression of weeds by crop density, cultivar selection, and nutrition requires better understanding of the extent to which rice interferes with the growth of this weed and how it responds to resource limitation due to rice interference. The growth of I. rugo...

Understanding farmers’ perception is important in the development of sustainable and cost-effective integrated pest management strategies. Hence, farmers’ perception on rice insect pests and pesticide use was evaluated by selected 112 farmers composed of 77% males and 23% females, over the rice growing areas of North Cotabato, Central Mindanao, Philippines. 62% of farmers that were interviewed ...

Rice is the major source of food for over half of the world’s population. As a model cereal crop, the complete genome sequence of rice has become fundamental for analyzing gene functions and relating them to practical applications in plants. At present, rice researchers devote much effort to generating mutants and tagged lines, or utilizing elite germplasms to clone important genes and identify...

The MIPS Rice (Oryza sativa) database (MOsDB; http://mips.gsf.de/proj/rice) provides a comprehensive data collection dedicated to the genome information of rice. Rice (O. sativa L.) is one of the most important food crops for over half the world's population and serves as a major model system in cereal genome research. MOsDB integrates data from two publicly available rice genomic sequences, O....

Rice is an important food grain crop and is consumed by majority of the human population. Nutrient management is an important aspect in rice to be given pivotal importance so as to attain sustainability of grain yield production. In the present chapter, aspects’ relating to integrated nutrient management in rice is critically reviewed. The effects of integrating chemical fertilizers with organi...

Do markets in less-developed countries abate consequences of climate stress? Rainfall is an important factor in rice production in Indonesia. This paper uses changes in regional rice prices across the 19 residencies in less-developed Java to assess how rice markets responded to variations in rainfall during 1935-1940. It finds that rice markets were highly integrated across Java. The El Niño-in...

Rice, Oryza sativa, also known as paddy rice is produced by at least 95 countries around the globe with China and India are the largest producers of rice in the world; while Thailand, Vietnam and America are the largest world rice exporters. To sustain rice productivity, advance agriculture technologies have always been deployed to increase the productivity of this food grain. This is due to th...

UNLABELLED The National Agricultural Biotechnology Information Center (NABIC) in South Korea reconstructed a RiceQTLPro database for gene positional analysis and structure prediction of the chromosomes. This database is an integrated web-based system providing information about quantitative trait loci (QTL) markers in rice plant. The RiceQTLPro has the three main features namely, (1) QTL marker...
