The brown planthopper (BPH) is the most serious insect pest of rice in Asia. The indica rice cultivar ADR52 carries two BPH resistance genes, BPH26 (brown planthopper resistance 26) and BPH25. Map-based cloning of BPH26 revealed that BPH26 encodes a coiled-coil-nucleotide-binding-site-leucine-rich repeat (CC-NBS-LRR) protein. BPH26 mediated sucking inhibition in the phloem sieve element. BPH26 ...

To identify the major factors contributing to the quality of commercial gochujang (fermented red pepper paste), metabolites were profiled by mass spectrometry. In principal component analysis, cereal type (wheat, brown rice, and white rice) and species of hot pepper (Capsicum annuum, C. annuum cv. Chung-yang, and C. frutescens) affected clustering patterns. Relative amino acid and citric acid l...

Article History: Received 14, June, 2015 Received in revised form 23, June, 2015 Accepted 13, July, 2015 Published online 28, July, 2015 Aqueous extract of leaves of Azadirachtaindica, Emblicaofficinalis, Pongamiaglabra and Acacia nilotca were tested in-vitroat 0.2% and 0.5% concentration using poisoned food technique for antimicrobial activity against mycelial growth of Magnaportheoryzaecausin...

Rice kernel dimensions affect the performance of various post-harvest processes. This study assessed variability trends in kernel dimensional distributions of Bengal (medium-grain), Cypress, and Drew (long-grains) rice varieties. Rice was harvested at various stages of maturity from Stuttgart and Keiser, Arkansas during the autumns of 1998, 1999, and 2000. Brown rice kernel dimensions decreased...

Bipolaris oryzae is a phytopathogenic fungus causing a brown spot disease in rice, and produces substance that strongly perturbs motility and membrane integrities of boar spermatozoa. The substance was isolated from the liquid culture of the fungal strain using extraction and a multi-step semi-preparative HPLC procedures. Based on the results of mass spectrometric and 2D NMR techniques, the bio...

This paper introduces an agent-based framework to modeling and simulate assessing rice area infested by brown plant hoppers from field to regional scales using agent-based and upscaling approach. Because detail levels of infestation rice area information are different from small scale to large scale, infestation rice area information are collected from fields in the Mekong Delta region-Vietnam ...

Rice is the staple food for nearly two-thirds of the world's population. Food components and environmental load of rice depends on the rice form that is resulted by different processing conditions. Brown rice (BR), germinated brown rice (GBR) and partially-milled rice (PMR) contains more health beneficial food components compared to the well milled rice (WMR). Although the arsenic concentration...

In 2006~2010, leaf spot symptoms, that is, small, yellow spots that turned into dark brown-to-black lesions surrounded by a yellow halo, were observed on Cymbidium spp. in Gongju, Taean, and Gapyeong in Korea. A Fusarium species was continuously isolated from symptomatic leaves; in pathogenicity testing, isolates caused leaf spot symptoms consisting of sunken, dark brown lesions similar to the ...

In Asia, more than 2000 million people obtain their 60–70% calories from a wide variety of rice cultivars and its products (Lin et al. 2011). The chemical composition of rice grain varies widely, depending on variety, soil and environment. Brown rice is the name given to dehusked paddy which retains the embryo and bran layers of the grain. Brown rice is rich in fibres, minerals, vitamins and ph...

Problems related to brown plant hopper outbreaks management in the Mekong Delta-Vietnam are complex and need aggregating information across administrative scales. Brown plant hoppers density and environmental indicators are main factors that support stakeholders have suitable decision making. Due to detail levels of information are different from field scale to region scale, upscaling informati...
