| Title: The Rice COLEOPTILE PHOTOTROPISM1 gene encoding an ortholog of Arabidopsis NPH3 is required for phototropism of coleoptiles and lateral translocation of auxin .
| | Author: Haga K Takano M Neumann R Iino M | | Journal: Plant Cell Citation: V : 17 ( 1 ) P : 103-15 Year: 2005 Type: ARTICLE | | Literature: oryza Field: abstract Doc ID: pub15598797 Accession (PMID): 15598797 | | Abstract: We isolated a mutant , named coleoptile phototropism1 ( cpt1 ) , from gamma-ray-mutagenized japonica-type rice ( Oryza sativa ) .
This mutant showed no coleoptile phototropism and severely reduced root phototropism after continuous stimulation .
A map-based cloning strategy and transgenic complementation test were applied to demonstrate that a NPH3-like gene deleted in the mutant corresponds to CPT1 .
Phylogenetic analysis of putative CPT1 homologs of rice and related proteins indicated that CPT1 has an orthologous relationship with Arabidopsis thaliana NPH3 .
These results , along with those for Arabidopsis , demonstrate that NPH3/CPT1 is a key signal transduction component of higher plant phototropism .
In an extended study with the cpt1 mutant , it was found that phototropic differential growth is accompanied by a CPT1-independent inhibition of net growth .
Kinetic investigation further indicated that a small phototropism occurs in cpt1 coleoptiles .
This response , induced only transiently , was thought to be caused by the CPT1-independent growth inhibition .
The 3H-indole-3-acetic acid applied to the coleoptile tip was asymmetrically distributed between the two sides of phototropically responding coleoptiles .
However , no asymmetry was induced in cpt1 coleoptiles , indicating that lateral translocation of auxin occurs downstream of CPT1 .
It is concluded that the CPT1-dependent major phototropism of coleoptiles is achieved by lateral auxin translocation and subsequent growth redistribution . | Matching Sentences:

| Title: Lower weight gain and hepatic lipid content in hamsters fed high fat diets supplemented with white rice protein , brown rice protein , soy protein , and their hydrolysates .
| | Author: Zhang H Bartley GE Mitchell CR Zhang H Yokoyama W | | Journal: J Agric Food Chem Citation: V : 59 P : 10927-33 Year: 2011 Type: In-Process | | Literature: oryza Field: abstract Doc ID: pub21913675 Accession (PMID): 21913675 | | Abstract: The physiological effects of the hydrolysates of white rice protein ( WRP ) , brown rice protein ( BRP ) , and soy protein ( SP ) hydrolyzed by the food grade enzyme , alcalase2 . 4 L , were compared to the original protein source .
Male Syrian Golden hamsters were fed high-fat diets containing either 20% casein ( control ) or 20% extracted proteins or their hydrolysates as the protein source for 3 weeks .
The brown rice protein hydrolysate ( BRPH ) diet group reduced weight gain 76% compared with the control .
Animals fed the BRPH supplemented diet also had lower final body weight , liver weight , very low density lipoprotein cholesterol ( VLDL-C ) , and liver cholesterol , and higher fecal fat and bile acid excretion than the control .
Expression levels of hepatic genes for lipid oxidation , PPARalpha , ACOX1 , and CPT1 , were highest for hamsters fed the BRPH supplemented diet .
Expression of CYP7A1 , the gene regulating bile acid synthesis , was higher in all test groups .
Expression of CYP51 , a gene coding for an enzyme involved in cholesterol synthesis , was highest in the BRPH diet group .
The results suggest that BRPH includes unique peptides that reduce weight gain and hepatic cholesterol synthesis .

| Title: Black rice ( Oryza sativa L ) extract attenuates hepatic steatosis in C57BL/6 J mice fed a high-fat diet via fatty acid oxidation .
| | Author: Jang HH Park MY Kim HW Lee YM Hwang KA Park JH Park DS Kwon O | | Journal: Nutr Metab ( Lond ) Citation: V : 9 P : 27 Year: 2012 Type: In-Data-Review | | Literature: oryza Field: abstract Doc ID: pub22458550 Accession (PMID): 22458550 | | Abstract: ABSTRACT : BACKGROUND : Two major risk factors for the onset of fatty liver disease are excessive alcohol intake and obesity , the latter being associated with non-alcoholic fatty liver disease ( NAFLD ) .
The aim of this study was to examine the effects of black rice extract ( BRE ) on hepatic steatosis and insulin resistance in high-fat diet-fed mice , providing a model of NAFLD .
METHODS : Twenty-four mice were randomly divided into three groups ( n = 8 in each group ) : normal fat diet ( ND ) , high fat diet ( HF ) , and high fat diet supplemented with 1% ( w/w ) BRE ( HF +1% BRE ) .
The experimental diets were fed for seven weeks .
RESULTS : A HF induced hepatic steatosis with significant increases in the serum levels of free fatty acids ( FFAs ) , triglyceride ( TG ) , total cholesterol ( TC ) , and insulin .
By contrast , supplementary BRE ( 10 g/kg of diet ) included in the HF alleviated hepatic steatosis and significantly decreased serum TG and TC levels ( p < 0 . 01 for both ) .
Dietary BRE also increased expression of fatty acid metabolism-related genes , including carnitine palmitoyltransferase ( CPT1A ) , acyl-CoA oxidase ( ACO ) , cytochrome P450 ( CYP4A10 ) , and peroxisome proliferator activated receptor ( PPAR ) -alpha ( p < 0 . 05 for all ) .
CONCLUSIONS : Dietary BRE supplementation improved serum lipid profiles and significantly enhanced mRNA expression levels of fatty acid metabolism-related genes , primarily via beta-oxidation and omega-oxidation in the liver .
Taken together , these findings suggest that a BRE-supplemented diet could be useful in reducing the risks of hepatic steatosis and related disorders , including hyperlipidemia and hyperglycemia .
