Molecular evidence on the origin and evolution of glutinous rice.
Glutinous rice is a major type of cultivated rice with long-standing cultural importance in Asia. A mutation in an intron 1 splice donor site of the Waxy gene is responsible for the change in endosperm starch leading to the glutinous phenotype. Here we examine an allele genealogy of the Waxy locus to trace the evolutionary and geographical origins of this phenotype. On the basis of 105 glutinou...
متن کاملFunctional Properties of Glutinous Rice Flour by Dry-Heat Treatment
Glutinous rice flour (GRF) and glutinous rice starch (GRS) were modified by dry-heat treatment and their rheological, thermal properties and freeze-thaw stability were evaluated. Compared with the native GRF and GRS, the water-holding ability of modified GRF and GRS were enhanced. Both the onset and peak temperatures of the modified samples increased while the endothermic enthalpy change decrea...
متن کاملMolecular analysis of Salamander family: the new alpine salamander Salamandra atra aurorae
A portion of the mitochondrial DNA from the 3' terminal of gene 12S rRNA to the 5' extremity of 16S rRNA gene has been amplified by PCR from Salamandra atra aurorae genomic DNA in order to define the taxonomic position of S. atra aurorae within the Salamandra species. Analysis of the molecular data indicated that S. a. aurorae is quite different from S. salamandra, whereas S. a. aurorae and S. ...
متن کاملThe First Salamander Defensin Antimicrobial Peptide
Antimicrobial peptides have been widely identified from amphibian skins except salamanders. A novel antimicrobial peptide (CFBD) was isolated and characterized from skin secretions of the salamander, Cynops fudingensis. The cDNA encoding CFBD precursor was cloned from the skin cDNA library of C. fudingensis. The precursor was composed of three domains: signal peptide of 17 residues, mature pept...
متن کاملOptimal Filtering in the Salamander Retina
The dark-adapted visual system can count photons wit h a reliability limited by thermal noise in the rod photoreceptors the processing circuitry bet.ween t.he rod cells and the brain is essentially noiseless and in fact may be close to optimal. Here we design an optimal signal processor which estimates the time-varying light intensit.y at the retina based on the rod signals. \Ve show that. the ...
