To determine the expression levels of genes related to the salt stress response in rice, gene expression profiles were investigated through microarray analysis using the rice mutant line Till-II-877. There were no significant changes in physiological response under salt stress of the mutant increased less than that in the WT. The intensity of gene expression was analyzed and compared between the wild type and mutant lines using a microarray. Among the most significantly affected pathways, α-linolenic acid metabolism and linoleic acid metabolism (in lipid metabolism), fructose and mannose metabolism and glycolysis-gluconeogenesis (in carbohydrate metabolism), cysteine and methionine metabolism (in amino acid metabolism), and carbon fixation (in the energy metabolism of photosynthetic organisms) showed changes in gene expression levels under salt stress. These results further our understanding of the effects of salt stress in rice and may aid in the development of salt-tolerant rice cultivars.

This study was carried out to confirm the effects of climate change to growth, yield and quality of rice by the global warming. By the study of Korea Meteorology Administration, the temperature of Korea increased 0.95℃ during last 34 years and the width of temperature increase be on an increasing trend gradually. As temperature increases, rice is faced with critical change such as growth duration shortening, heading acceleration, yield decrease and quality deterioration. So, we studied the rice growth and yield change by the temperature increase. To confirm the effects of temperature increase, rice cultivars such as early maturing Unkwangbyeo, medium maturing Hwayoungbyeo and late maturing Nampyeongbyeo were transplanted on 1, 15, 30 of June inner transparent vinyl house which was treated by different temperature. The increased mean temperature were 1.4℃～3.5℃, respectively, compared to outer field. The growth duration from transplanting to heading were shortened by the temperature increase. In June 1 transplanting, especially the growth duration of early maturing Unkwangbyeo was shortened greatly by temperature increase. As temperature increases, rice yield decreased in most cases. In 1.4℃ temperature increase, rice yield of June 15 transplanting were higher than those of other transplanting, but in 2.1℃ or more temperature increase, the rice yield of June 30 transplanting were similar or more than those of other transplanting.

The influence of elevated CO2 and temperature on growth parameters, biomass production and its partitioning of rice (Oryza sativa L.cv. Chukwangbyeo) were investigated in the three experiments (1991-1993). Rice plants were grown from transplanting to harvest at either ambient(350ppm) or elevated CO2 concentrations (690 or 650ppm) in combination with either four or seven temperature regimes ranging form ambient temperature (AT) to AT plus 3℃.From transplanting to panicle initiation, crop growth rate (CGR) was enhanced by up to 27% with elevated CO2 , primarily due to an an increase in leaf area index. although net assimilatiion rate was also greater at elevated CO2. The effect of elevated CO2 varied with temperature. During the reproductive phase, CGR declined linearly with increased temperature, and was greater at elevated CO2 . Elevated CO2 increased final crop biomass and panicle weight 30% respectively at AT(27.6℃ : 1991) . However, there was no significant effect of elevated CO2 on panicle weight at AT plus 3℃, where severe spikelet sterility occurred. There was no significant effect of elevated CO2 on panicle weight at AT plus 3℃, where severe spikelet sterility occurred. There was also no effect of CO2 on biomass pratitioning into vegetative and reproductive organs (harvest index)) at AT, although higher temperature could affect that by inducing spikelet sterility. These results suggest that elevated CO2 could enhance rice producivity througth promoted growth and biomass production , but its positive effects may be less at higher temperatures.
