Availability of rice straw Si to rice plants
Soil Science and Plant Nutrition, 1991Abstract A pot experiment was conducted to estimate the availability to rice plants of Si contained in rice straw. To separate the effect of straw application on Si availability in soil, two kinds of rice straws, which contained 15.5% (+ Si straw) and 0.2% SiO2 (—Si straw), were used at a rate of 1% of air-dry soil, respectively.

Transgenic plants are becoming indispensable tools for studies of gene regulation in higher plants (Schell, 1987; Benfey and Chua, 1989). Furthermore, with the rapid progress in isolation and characterization of plant genes, it is considered to be one of the most promising approaches for crop improvement (Gasser and Fraley, 1989).

Construction of rice cybrid plants
Molecular and General Genetics MGG, 1989The mitochondrial genomes of rice cells were transferred to a fertile rice variety (N8) from a cytoplasmic male sterile variety (CMS) by asymmetric protoplast fusion based on metabolic complementation. Protoplasts derived from CMS were X-irradiated (125 krad) and electrofused with protoplasts which had been treated with iodoacetamide.

Rice Yielding and Plant Hormones
2008Food shortage is a serious global problem in this century. According to FAO estimates, 852 million people worldwide were undernourished in 2000–2002 (FAO 2004). The global population, now at 6.4 billion, is still growing rapidly and is supposed to reach 8.9 billion by 2050 (UNFPA 2004).

Genetic Engineering in Rice Plants
1994Recently, gene transfer into higher plants has made it possible to analyse foreign gene expression in transgenic rice plants. We have constructed a chimeric gene consisting of the promoter, 1st exon, and 1st intron of a maize polyubiquitin gene (Ubi-1) and the coding sequence of the bar gene from Streptomyces hygroscopicus.

Two studies describe how regulatory variation at the rice gene OsSPL14 can lead to altered plant morphology and improve grain yield. These studies support the possibility of improving rice yield through changing plant architecture.

Publisher Summary This chapter emphasizes the nutritional physiology of the rice plant from the agronomic point of view. During the period from 1900 to 1930, rice scientists attempted to define techniques that would enable farmers to obtain maximum yields from existing varieties under the condition of minimal fertilizer use.
