Progress on the research and development of insect-resistant transgenic rice, especially expressing insecticidal proteins from Bacillus thuringiensis (Bt), in China has been rapid in recent years. A number of insect-resistant transgenic rice lines/varieties have passed restricted and enlarged field testing, and several have been approved for productive testing since 2002 in China, although none...

Principal component analysis (PCA) is a classical statistical method. It is based on the statistical representation of a random variable. This linear transform has been widely used in data analysis and compression.Impact of PCA is affecting the research work in now a days in the various field like application of Image Processing, pattern recognition ,Neural network and etc . We know that rice i...

A rice (Oryza sativa) experiment was conducted to determine the accuracy of a fast tissue testing method using a Horiba Cardy K+ meter. Rice was field-grown in three soil potassium regimes. At three early reproductive growth stages (R0, R1, and R2), stem samples from the basal six inches of rice plants were collected and analyzed for K content. Basal stem samples were tested with extracted sap ...

OsEBP-89 gene encodes an ethylene responsive element binding protein (EREBP) transcription factor from rice (Oryza sativa). Northern blot analysis revealed that OsEBP-89 was expressed in root, stem, seeds, flowers and leaves of rice. Histochemical assay showed that GUS expressed mainly in phloem of vascular tissues of the root and stem transition region (RST), basal part of sheath roots, stem n...

2 Morphological Structure of the Dene Verb The morphological structure of verbs in Dene languages is considered to be about as complex as it can get among the languages of the world. However, the overall structure, with outer (disjunct), inner (conjunct), and stem ‘zones’ of verb (cf. Kari 1989) is not generally, and thus computationally, difficult to model. What is seen as most challenging pri...

The leaf angle between stem and sheath (SSA) is an important rice morphological trait. The objective of this study was to develop and validate a dynamic SSA model under different nitrogen (N) rates for selected rice cultivars. The time-course data of SSA were collected in three years, and a dynamic SSA model was developed for different main stem leaf ranks under different N rates for two select...

rice is the world's most important food crop. to decrease the damage of  rice pests, development of insect pest management strategies in rice is necessary. biennial results for determination of a suitable method to control striped stem borer in rice showed that integration of two methods of control (biological and mechanical) is a feasible effort to reduce stem borer infestation. to assure...

The objective of this study is to investigate tungsten (W) contamination in soil and its enrichment in rice in the area of the world's largest and longest-operating W mines in China. Root zone soil and rice plants were sampled at 15 sites in the agricultural field adjacent to W mines and analyzed for Al, Fe, Mn, Sc, and W contents and W chemical forms in the soil samples and W contents in the r...

In this study, the hydrolysis of pretreated sorghum stem and rice husk was investigated at various initial enzyme concentrations and substrate loadings. The slowdown in enzymatic hydrolysis of lignocellulosic materials with conversion has often been attributed to decreasing the activity of enzyme. A kinetic model was developed and expressed mathematically based on enzyme deactivation for enzyma...
