Salinity is a major environmental stress that limits agricultural production and geographical distribution of plants. In a previous study, it has been shown that OsMsr9 was induced by cold, drought and heat stresses. However, functions of OsMsr9 at physiological and molecular levels are still unknown. Here, we report that OsMsr9 plays roles in salt(More)
Abiotic stress seriously affects the yield of rice (Oryza sativa L.). Grain yield in rice is multiplicatively determined by the number of panicles, number of grains per panicle, and grain weight. Here, we describe the molecular and functional characterization of STRESS_tolerance and GRAIN_LENGTH (OsSGL), a rice gene strongly up-regulated by a wide spectrum(More)
Calmodulin-like (CML) genes regulate plant growth, development, and responses to abiotic stresses such as salinity and drought. Many genes encoding CML proteins have been identified from rice (Oryza sativa), but their functions remain largely unknown. Our characterization of one putative CML gene, OsDSR-1 (O. sativa Drought Stress Response-1), showed that(More)
The small heat shock proteins (sHSPs) are most prevalent in plants and are believed to play an important role in stress tolerance. Our microarray and qRT-PCR analyses of rice plants showed that the gene Oryza sativa Multi-Stress-Responsive 4 (OsMSR-4) is induced by heat, drought, and cold in different tissues at various developmental stages. OsMSR-4 encodes(More)
Drought is a major environmental factor that limits plant growth and crop productivity. Genetic engineering is an effective approach to improve drought tolerance in various crops, including rice (Oryza sativa). Functional characterization of relevant genes is a prerequisite when identifying candidates for such improvements. We investigated OsSGL (Oryza(More)
It is well known that β-adrenoceptors (β-ARs) play a critical role in emotional arousal and stressful events, but the specific contributions of the β2-AR subtype to the psychological disorders are largely unknown. To investigate whether β2-AR are involved in anxiety-like behavior and reward to addictive drugs, we conducted a series of behavioral tests on(More)
