We report here the isolation and characterization of a new endo-1,3-β-glucanase (1,3-β-GLU) cDNA, OsGLN2, that is expressed both in flowers and in germinating seeds of rice (Oryza sativa L.). The isolated OsGLN2 gene encoded a protein which displayed 72%, 93% and 92% identity at the amino acid level with those encoded by barley GII, rice Gns4 and glu1(More)
Arabidopsis thaliana was thought to contain two spermine synthase genes, ACAULIS 5 (ACL5) and SPMS. Recent investigations, however, revealed that the ACL5 gene encodes thermospermine synthase. In this study, we have established a simple method to separate two isomers of tetraamine, spermine and thermospermine, in extracts from plant tissues of less than 500(More)
We have investigated the regulation of the rice ( Oryza sativa) gene OsSAMDC, which encodes an S-adenosyl-L-methionine decarboxylase (SAMDC) involved in polyamine biosynthesis. Clones representing genes differentially expressed at 5°C and 20°C were isolated from a cDNA library prepared from the chilling-tolerant japonica -type cultivar Yukihikari. The(More)
Good indoor air quality (IAQ) can contribute to the safety, health and comfort of the people. Since indoor exposure to air contaminants penetrating from the indoor air contaminant sources depends on a number of parameters such as the ventilation rate, the geometric characteristics of the indoor environment, the indoor removal mechanisms and the(More)
Indoor air quality (IAQ) is a key factor for ensuring the safety, health and comfort of the people. Since physical variables describing IAQ, such as the concentration of volatile organic compounds (VOCs), concentrations of gaseous air contaminants and that of other toxic gases need to be closely monitored, concept of distributed monitoring and control(More)
In acoustic energy, harvesting energy is captured from external noise sources, controlled and stored for various applications. Despite the prevalence of acoustic energy a major challenge of energy harvesting is the low power density. Acoustic Energy Harvester consists of a resonator, an acoustic transducer and a storage device. When acoustic resonator is(More)
A model is presented of a composite beam with one elastic and one piezoelectric layer. A reduced set of piezoelectric equations of state that has only the longitudinal components of stress and strain and the transverse components of electric field and charge density is consistently used to include the effect of piezoelectric coupling in all the equations.(More)
Differential clones from submergence stress and control treatment from rice seedlings were isolated by the differential screening method. One of the clones, OsGAPDH, represented a gene that was expressed at high level during 12-h submergence. A homology search of GenBank databases showed that OsGAPDH had significant sequence homology with maize(More)
