| Title: Short grain1 decreases organ elongation and brassinosteroid response in rice .
| | Author: Nakagawa H Tanaka A Tanabata T Ohtake M Fujioka S Nakamura H Ichikawa H Mori M | | Journal: Plant Physiol Citation: V : 158 P : 1208-19 Year: 2012 Type: MEDLINE | | Literature: oryza Field: abstract Doc ID: pub22209874 Accession (PMID): 22209874 | | Abstract: We identified a short-grain mutant ( Short grain1 ( Sg1 ) Dominant ) via phenotypic screening of 13 , 000 rice ( Oryza sativa ) activation-tagged lines .
The causative gene , SG1 , encodes a protein with unknown function that is preferentially expressed in roots and developing panicles .
Overexpression of SG1 in rice produced a phenotype with short grains and dwarfing reminiscent of brassinosteroid ( BR ) -deficient mutants , with wide , dark-green , and erect leaves .
However , the endogenous BR level in the SG1 overexpressor ( SG1 : OX ) plants was comparable to the wild type .
SG1 : OX plants were insensitive to brassinolide in the lamina inclination assay .
Therefore , SG1 appears to decrease responses to BRs .
Despite shorter organs in the SG1 : OX plants , their cell size was not decreased in the SG1 : OX plants .
Therefore , SG1 decreases organ elongation by decreasing cell proliferation .
In contrast to the SG1 : OX plants , RNA interference knockdown plants that down-regulated SG1 and a related gene , SG1-LIKE PROTEIN1 , had longer grains and internodes in rachis branches than in the wild type .
Taken together , these results suggest that SG1 decreases responses to BRs and elongation of organs such as seeds and the internodes of rachis branches through decreased cellular proliferation .

| Title: [ Interactions between macromolecular adjuvants and drugs .
Part 18 : The binding behaviour of sodium carboxymethylcellulose and other macromolecules towards streptomycin sulphate ( authors transl ) ] | | Author: Keipert S Voigt R | | Journal: Pharmazie Citation: V : 34 ( 9 ) P : 548-51 Year: Type: ARTICLE | | Literature: oryza Field: abstract Doc ID: pub542488 Accession (PMID): 542488 | | Abstract: Unlike the other macromolecules under investigation ( polyvinylpyrrolidone , methylcellulose , polyvinyl alcohol ) , sodium carboxymethylcellulose acts on streptomycin sulphate , which leads to isolable precipitates .
By equilibrium dialysis in electrolyte-free and electrolyte-containing solutions , the interaction was characterized in more detail and described by Donnan curves .
The associates ( which contained , on an average , 40% of streptomycin ) proved to be resistant to light and air , and stable to thin-layer chromatography .
Microbiological assays on the test strain Bacillus subtilis SG119 revealed a decrease in activity of the streptomycin-sodium carboxymethylcellulose associates compared to pure streptomycin ( tested in the solid form , using rice granulate as a carrier substance ) .
In contrast , the associate was as efficient as the antibiotic when dissolved in a concentrated solution of sodium chloride .
