Over the past 10 years, genomes of cultivated rice cultivars and their wild counterparts have been sequenced although most efforts are focused on genome assembly and annotation of two major cultivated rice (Oryza sativa L.) subspecies, 93-11 (indica) and Nipponbare (japonica). To integrate information from genome assemblies and annotations for better analysis and application, we now introduce a...

The concept of critical nitrogen (Nc) concentration can be implemented to diagnose in-season plant nitrogen (N) status for optimizing N fertilizer management. The Nc dilution curves have been established for rice (Oryza sativa L.) grown in different climatic regions, yet no attempt has been made to develop the Nc dilution curve for double cropping rice regions. This study was undertaken to deve...

In modern agriculture, climate change, environmental degradation, and natural resource depletion constitute one of the major potential issues for sustainable crop production management. Integrated pest management (IPM) is a promising technology environment. Insect pests weeds have long posed danger to rice systems, resulting in severe output losses. Although insect, pest, weed control has remai...

barnyardgrass has always been considered as the most important weed of rice all over the world. meanwhile, establishment of new species of this genus which is more adaptable to paddy ecosystem will increase the importance of this genus as a new threat to rice. in order to evaluate the competition of two species of barnyardgrass with rice, an experiment was conducted at rice research institute o...

This paper attempts to model the price relationship between two leading exporters of rice, being Thailand and Vietnam. The motivation of such research is to reveal whether prices are integrated and determine whether any causal relationships exist among prices for rice. Given the perception that exists regarding the imperfectly competitive nature of the rice market, especially in the high qualit...

SUMMARY Rice (Oryza sativa L.) is an important model monocot and cereal crop. While the rice genome sequence has been published and annotated, relatively little is known about the transcriptional networks that regulate rice gene expression. For this reason, we have developed Osiris, a database containing promoter sequences, predicted transcription factor (TF) binding sites, gene ontology annota...

[1] Modification of continental land for agricultural use has increased over the last century. Atmospheric impact of this land use change has only been addressed for a few ecosystems and compounds. This paper provides, to date, the most comprehensive examination of gaseous emissions from rice paddies. We report seasonal emission ranges and integrated emission totals for 55 chemical species. Thi...
