Abstract:
A novel floral organ mutant of rice (Oryza sativa L. subsp. indica), termed pistilloid-stamen (ps) here, has flowers with degenerated lemma and palea, with some stamens transformed into pistils and pistil–stamen chimeras. Genetic analysis confirmed that the ps trait is controlled by a single recessive gene. F2 and F3 segregation populations derived from PS ps heterozygote crossed with Oryza sativa subsp. indica 'Luhui-17' (PS PS) were used for molecular mapping of the gene using simple sequence repeat (SSR) markers. With 97 recessive individuals from an F2 segregation population, the ps locus

Abstract:
RNA recognition motifs as important regulators of gene expression are highly conserved in animals and plants. The FCA floral promotion gene in Arabidopsis encodes a protein, containing two RNA recognition motifs (RRM) and a WW protein interaction domain. Here we isolated FCA cDNA from rice. FCA in rice (rFCA) was homologous to FCA-gamma of Arabidopsis and contained conserved domains. To investigate the function of RRM domain, fragment RRM1 and RRM2 of rFCA were introduced into rice subspecies Oryza sativa L. subsp. Indica var. 9311 and another rice subspecies Oryza sativa L. subsp. Japonica va

Abstract:
The functional stay-green trait gives leaves a longer duration of greenness and photosynthetic capacity during the grain-filling period. We developed two independent recombinant inbred line populations from the intra- and intersubspecific crosses of Oryza sativa L. subsp. japonica ‘Suweon490’ (japonica) × O. sativa subsp. japonica ‘SNU-SG1’ (japonica) and O. sativa subsp. indica ‘Andabyeo’ (indica) × O. sativa subsp. japonica ‘SNU-SG1’ (japonica), respectively. The common parental line ‘SNU-SG1’ was the functional source for the stay-green trait. Quantitative trait locus (QTL) mapping based on

The taxonomic position of three Lactobacillus -like micro-organisms (strains SG293T, SG296 and SG310) isolated from fermented rice grain (Oryza sativa L. subsp. japonica) in Japan was investigated. These heterofermentative lactic acid bacteria were Gram-stain-positive, rod-shaped, facultatively anaerobic, non-motile, non-spore-forming and did not show catalase activity. 16S rRNA gene sequence analysis of strain SG293T revealed that the type strains of Lactobacillus malefermentans (98.3 %), Lactobacillus odoratitofui (96.2 %), Lactobacillus similis (96.1 %), Lactobacillus kimchicus (96.1 %), La

Abstract:
Retrotransposons are ubiquitous in higher plant genomes. The presence or absence of retrotransposons in whole genome and high throughput genomic sequence (HTGS) from cultivated and wild rice was investigated to understand the organization and evolution of retrotransposon insertions in promoter regions. Approximately half of the Oryza sativa subsp. japonica ‘Nipponbare’ promoters with retrotransposons conserved in Oryza sativa subsp. indica ‘93-11’ and four wild rice species showed higher sequence conservation in retrotransposon than nonretrotransposon regions. We further investigated, in detai

Abstract:
The objective of this work was to evaluate the physiological changes that occur in different leaves during the early and late grain-filling stages of two rice genotypes (Oryza sativa subsp. indica , BRS Pelota cultivar, and O. sativa subsp. japonica , BRS Firmeza cultivar), which present differences in grain yield potential. The plants were cultivated in greenhouse. Pigment content, chlorophyll fluorescence, electron transport and oxygen evolution rate were determined in the grain-filling stage, from the first to the forth leaf (top to bottom).

Abstract:
Thionins are a family of antimicrobial peptides. We performed in silico expression analyses of the 44 rice (Oryza sativa) thionins (OsTHIONs). Modulated expression levels of OsTHIONs under different treatments suggest their involvement in many processes, including biotic, abiotic, and nutritional stress responses, and in hormone signaling. OsTHION15 (LOC_Os06g32600) was selected for further characterization based on several in silico analyses. OsTHION15 in O. sativa subsp. indica ‘KDML 105’ was expressed in all of the tissues and organs examined, including germinating seed, leaves, and roots o

Abstract:
The mutations that convey the white pericarp phenotype to rice ( Oryza sativa subsp. japonica) are in a regulatory gene, Rc. We have identified a genetic difference between the cultivar ‘Perla’ and its natural red rice mutant ‘Perla Rosso’ in the Rc gene. The deletion of a G base restores the reading frame for the Rc gene, lost by the original 14 bp deletion that gave rise to white rice.
