Oleanane-type triterpene is one of the most widespread triterpenes found in plants, together with the lupane type, and these two types often occur together in the same plant. Bruguiera gymnorrhiza (L.) Lamk. and Rhizophora stylosa Griff. (Rhizophoraceae) are known to produce both types of triterpenes. Four oxidosqualene cyclase cDNAs were cloned from the(More)
Glycinebetaine is an important osmoprotectant in bacteria, plants, and animals, but only little information is available on the synthesis of glycinebetaine in tree plants. Among four mangrove species, glycinebetaine could be detected only in Avicennia marina. Pinitol was the main osmoprotectant in the other three species. The level of glycinebetaine in A.(More)
Salinity is a major abiotic stress that seriously limits plant growth and crop productivity. The halophytic Rhizophora stylosa is useful for the study of the molecular mechanisms behind salinity tolerance in mangrove trees. To isolate anti-salt stress genes from mangrove plants, a cDNA library of R. stylosa roots was constructed and screened for(More)
Members of the mangrove genus Rhizophora represent the most commonly occurring and highly valued species in the Indo-West Pacific region. However, to date, few studies have been directed towards the understanding of their genetic variation. The levels and patterns of genetic variation at chloroplast and nuclear gene regions were studied in R. apiculata, R.(More)
Mangrove forests are ecologically important but globally threatened intertidal plant communities. Effective mangrove conservation requires the determination of species identity, management units, and genetic structure. Here, we investigate the genetic distinctiveness and genetic structure of an iconic but yet taxonomically confusing species complex(More)
The halophytic Kandelia candel and Bruguiera gymnorrhiza are ideal model for studying the molecular mechanisms of salinity tolerance in mangrove plants. The correlation between mRNA expression of four oxidosqualene cyclase (OSC) genes namely, KcMS multifunctional terpenoid synthase and KcCAS cyloartenol synthase (K. candel), BgbAS beta-amyrin synthase and(More)
We present appearance-based virtual view generation which allows viewers to y through a real dynamic scene. The scene is captured by synchronized multiple cameras. Arbitrary views are generated by interpolating two original camera-view images near the given viewpoint. The quality of the generated synthetic view is determined by the precision, consistency(More)
In this paper, we present an “appearance-based” virtual view generation method for temporally-varying events taken by multiple cameras of the “3D Room”, developed by our group. With this method, we can generate images from any virtual view point between two selected real views. The virtual appearance view generation method is based on simple interpolation(More)
We present an appearance-based virtual view generation method that allows viewers to fly through a real dynamic scene. The scene is captured by multiple synchronized cameras. Arbitrary views are generated by interpolating two original camera-views near the given viewpoint. The quality of the generated synthetic view is determined by the precision,(More)
Homology based PCRs with degenerate primers designed from the conserved sequences among the known oxidosqualene cylases (OSCs) have resulted in cloning of a triterpene synthase (KcMS) from the young roots of Kandelia candel (L.) Druce (Rhizophoraceae). KcMS consists of a 2286 bp open reading frame, which codes for 761 amino acids. The deduced amino acid(More)
