We isolated cDNAs encoding betaine aldehyde dehydrogenase (BADH, EC from the salt-tolerant Poaceae, Zoysia tenuifolia by polymerase chain reactions. Zoysia betaine aldehyde dehydrogenase 1 (ZBD1) is 1892bp long and codes for 507 amino acids. The deduced amino acid sequence of ZBD1 is 88% similar to the sequence of rice BADH. Ten cDNA clones were(More)
Apomixis is an intriguing asexual mode of reproduction, because it produces maternal clones that permit vegetative reproduction through seeds. Guineagrass (Panicum maximum) has both facultative aposporous apomixis and obligate sexual modes of reproduction. Despite the importance of apomixis in guineagrass, expressed sequence tags (ESTs) for this condition(More)
Polyembryony, in which multiple somatic nucellar cell-derived embryos develop in addition to the zygotic embryo in a seed, is common in the genus Citrus. Previous genetic studies indicated polyembryony is mainly determined by a single locus, but the underlying molecular mechanism is still unclear. As a step towards identification and characterization of the(More)
Restoration of a high potential (HP) form of cytochrome b-559 (Cyt b-559) from a low potential (LP) form was the primary process in the reconstitution of O2-evolving center during the photoreactivation of Tris-inactivated chloroplasts. In normal chloroplasts, about 0.5 to 0.7 mol of Cyt b-559 was present in the HP form per 400 chlorophyll molecules.(More)
Erianthus arundinaceus, a member of the Saccharum complex, is of interest as a potential resource for sugarcane improvement and as a bioenergy crop. Genetic analyses of germplasm collections of E. arundinaceus are being used increasingly. To expand the genomic resources in E. arundinaceus, we aimed at developing simple sequence repeat markers. Using(More)
The genera Erianthus and Miscanthus, both members of the Saccharum complex, are of interest as potential resources for sugarcane improvement and as bioenergy crops. Recent studies have mainly focused on the conservation and use of wild accessions of these genera as breeding materials. However, the sequence data are limited, which hampers the studies of(More)
Rhodes grass (Chloris gayana) is one of the most important warm-season forage grasses. It is cultivated in tropical and subtropical parts of the world and is mostly used for grazing and hay production. We have established a particle-bombardment transformation protocol for rhodes grass using multiple-shoot clumps (MSCs) as the target tissue. A vector pAHC25(More)
We evaluated the ploidy levels and tissue culture responses of 16 Japanese Miscanthus accessions, which are registered and vegetatively maintained in the National Agriculture and Food Research Organization GeneBank, Japan, to screen suitable genotypes for the molecular breeding of Miscanthus species. A ploidy analysis showed that most M. sinensis and M.(More)
Erianthus arundinaceus, part of the Saccharum complex, is increasingly important as a bioenergy crop and a potential resource for sugarcane improvement. Germplasm is widely distributed in the tropical zone in Southeast Asia and southern China, and has been found in the subtropical and temperate zones in Japan. Here, we investigated the 2C DNA content and(More)
