Macronuclear Genome Sequence of the Ciliate Tetrahymena thermophila, a Model Eukaryote
The ciliate Tetrahymena thermophila is a model organism for molecular and cellular biology. Like other ciliates, this species has separate germline and soma functions that are embodied by distinctExpand
BRITTLE CULM1, Which Encodes a COBRA-Like Protein, Affects the Mechanical Properties of Rice Plants Article, publication date, and citation information can be found at
The classic rice mutant brittle culm1 (bc1) is characterized and isolated using a map-based cloning approach and it is suggested that BC1, a gene that controls the mechanical strength of monocots, plays an important role in the biosynthesis of the cell walls of mechanical tissues. Expand
Endophytic Bacterial Diversity in Rice (Oryza sativa L.) Roots Estimated by 16S rDNA Sequence Analysis
This is the first report that archaea has been identified as endophytes associated with rice by the culture-independent approach, and the results suggest that the diversity of endophytic bacteria is abundant in rice roots. Expand
Real-Time Evolution of New Genes by Innovation, Amplification, and Divergence
The innovation-amplification-divergence model is described in which the new function appears before duplication and functionally distinct new genes evolve under continuous selection, and one example fitting this model is a preexisting parental gene in Salmonella enterica that has low levels of two distinct activities. Expand
Mutations of genes in synthesis of the carotenoid precursors of ABA lead to pre-harvest sprouting and photo-oxidation in rice
The results suggest that the impairment of carotenoid biosynthesis causes photo-oxidation and ABA-deficiency phenotypes, of which the latter is a major factor controlling the PHS trait in rice. Expand
Structural and Regulatory Genes Required to Make the Gas Dimethyl Sulfide in Bacteria
It is demonstrated that the bacterial gene dddD is required for this process and that its transcription is induced by the DMSP substrate, and the inferred enzymatic mechanism for DMS liberation involves an initial step in which DMSP is modified by addition of acyl coenzyme A, rather than the immediate release of DMS by a DMSP lyase, the previously suggested mechanism.

Characterization of a novel plant growth-promoting bacteria strain Delftia tsuruhatensis HR4 both as a diazotroph and a potential biocontrol agent against various plant pathogens.
Comparisons of characteristics with other known species of the genus Delftia suggested that strain HR4 was a novel dizotrophic PGPB strain, and based on phenotypic, physiological, biochemical and phylogenetic studies, it could be classified as a member of D. tsuruhatensis. Expand
Novel roles for KLF1 in erythropoiesis revealed by mRNA-seq.
A cis-regulatory module bound by KLF1, GATA1, TAL1, and EP300 that coordinates a core set of erythroid genes is defined that drives high-level expression of otherwise ubiquitously expressed genes in erystroid cells. Expand
Molecular dissection of bacterial acrylate catabolism--unexpected links with dimethylsulfoniopropionate catabolism and dimethyl sulfide production.
This first description of genes involved in acrylate catabolism in any organism shows that the relationship between the catabolic pathways of acrylated and DMSP differs from that which had been suggested in other bacteria. Expand
Leifsonia ginsengi sp. nov., isolated from ginseng root.
A Gram-positive, rod-shaped, non-motile bacterium, designated strain wged11T, was isolated from the root of ginseng, and its taxonomic position was established using a polyphasic approach, showing that this organism formed a robust clade with recognized species of the genus Leifsonia. Expand
