J Syst Evol Microbiol .
Citation: V : 50 Pt 2 ( ) P : 823-9 Year: 2000 Type: ARTICLE | | Literature: oryza Field: abstract Doc ID: pub10758893 Accession (PMID): 10758893 | | Abstract: Eight Gram-negative , aerobic , rod-shaped and peritrichously flagellated strains were isolated from flowers of the orchid tree ( Bauhinia purpurea ) and of plumbago ( Plumbago auriculata ) , and from fermented glutinous rice , all collected in Indonesia .
The enrichment culture approach for acetic acid bacteria was employed , involving use of sorbitol medium at pH 3 . 5 .
All isolates grew well at pH 3 . 0 and 30 degrees C They did not oxidize ethanol to acetic acid except for one strain that oxidized ethanol weakly , and 0 . 35% acetic acid inhibited their growth completely .
However , they oxidized acetate and lactate to carbon dioxide and water .
The isolates grew well on mannitol agar and on glutamate agar , and assimilated ammonium sulfate for growth on vitamin-free glucose medium .
The isolates produced acid from D-glucose , D-fructose , L-sorbose , dulcitol and glycerol .
The quinone system was Q-10 .
DNA base composition ranged from 59 . 3 to 61 . 0 mol% G + C Studies of DNA relatedness showed that the isolates constitute a single species .
Phylogenetic analysis based on their 16S rRNA gene sequences indicated that the isolates are located in the acetic acid bacteria lineage , but distant from the genera Acetobacter , Gluconobacter , Acidomonas and Gluconacetobacter .
On the basis of the above characteristics , the name Asaia bogorensis gen . nov . , sp . nov . is proposed for these isolates .
The type strain is isolate 71T ( = NRIC 0311T = JCM 10569T ) . | Matching Sentences:

| Title: Coronatine elicits phytoalexin production in rice leaves ( Oryza sativa L ) in the same manner as jasmonic acid .
| | Author: Tamogami S Kodama O | | Journal: Phytochemistry Citation: V : 54 ( 7 ) P : 689-94 Year: 2000 Type: ARTICLE | | Literature: oryza Field: abstract Doc ID: pub10975503 Accession (PMID): 10975503 | | Abstract: The phytotoxin coronatine induced the accumulation of the flavonoid phytoalexins sakuranetin and momilactone A in rice leaves .
Coronatine-inducible sakuranetin production was under the control of kinetin and ascorbic acid ( AsA ) , as observed with jasmonic acid ( JA ) .
The effects of kinetin and AsA on the activity of coronatine indicated that coronatine might elicit sakuranetin production in a manner similar to JA .
The similarity of both their structures and the manner of elicitation of coronatine and JA suggest that they might interact at the same active site ( s ) to lead to phytoalexin production . | Matching Sentences:

| Title: Moisture desorption isotherms of medium-grain rough rice .
| | Author: Basunia MA Abe T | | Journal: Citation: V : 37 ( 3 ) P : 205-219 Year: 2001 Type: ARTICLE | | Literature: oryza Field: abstract Doc ID: pub11172858 Accession (PMID): 11172858 | | Abstract: Moisture desorption isotherms ( EMC/ERH ) of medium-grain rough rice ( Japonica variety ) were determined using a constant environment chamber for various combinations of air temperature ( 11 . 8-51 . 0 degrees C ) and relative humidity ( 37 . 1-89 . 7% ) .
The initial moisture contents were in the range of 24 . 7-41 . 6% dry basis .
A thin-layer technique was used to achieve uniform drying .
Each test was continued until the moisture content change in 24h was less than 0 . 1% dry basis .
The final moisture content was considered as the dynamic equilibrium moisture content .
Four three-parameter EMC/ERH equations , the modified Henderson , modified Chung-Pfost , modified Oswin and modified Halsey equations , were compared for their ability to fit the experimental EMC/ERH data .
The residual sum of squares ( RSS ) and standard error of estimate ( SEE ) were adopted as the criteria to evaluate the fitting performance of the models .
The modified Chung-Pfost equation was identified as the most appropriate equation for representing the EMC/ERH desorption isotherms of rough rice .
Coefficients for equilibrium moisture content as a function of equilibrium relative humidity and temperature are given .
The EMC/ERH data obtained in this study agreed well with previously published data .
However the average isotherm , combining desorption and adsorption data , of ASAE does not predict the desorption EMC of rough rice accurately .

| Title: Characterization of rice anthranilate synthase alpha-subunit genes OASA1 and OASA2 .
Tryptophan accumulation in transgenic rice expressing a feedback-insensitive mutant of OASA1 .
| | Author: Tozawa Y Hasegawa H Terakawa T Wakasa K | | Journal: Plant Physiol .
Citation: V : 126 ( 4 ) P : 1493-506 Year: 2001 Type: ARTICLE | | Literature: oryza Field: abstract Doc ID: pub11500548 Accession (PMID): 11500548 | | Abstract: Anthranilate synthase ( AS ) is a key enzyme in the synthesis of tryptophan ( Trp ) , indole-3-acetic acid , and indole alkaloids .
Two genes , OASA1 and OASA2 , encoding AS alpha-subunits were isolated from a monocotyledonous plant , rice ( Oryza sativa cv Nipponbare ) , and were characterized .
A phylogenetic tree of AS alpha-subunits from various species revealed a close evolutionary relationship among OASA1 and Arabidopsis ASA2 , Ruta graveolens AS alpha 2 , and tobacco ASA2 , whereas OASA2 , Arabidopsis ASA1 , and R graveolens AS alpha 1 were more distantly related .
OASA1 is expressed in all it issues tested , but the amount of its mRNA was greater in panicles than in leaves and roots .
The abundance of OASA2 transcripts is similar among it issues and greater than that of OASA1 transcripts ; furthermore , OASA2 expression was induced by a chitin heptamer , a potent elicitor , suggesting that OASA2 participates in secondary metabolism .
Expression of wild-type OASA1 or OASA2 transgenes did not affect the Trp content of rice calli or plants .
However , transformed calli and plants expressing a mutated OASA1 gene , OASA1 ( D323N ) , that encodes a protein in which aspartate-323 is replaced with asparagine manifested up to 180 and 35-fold increases , respectively , in Trp accumulation .
These transgenic calli and plants were resistant to 300 microM 5-methyl-Trp , and AS activity of the calli showed a markedly reduced sensitivity to Trp .
These results show that OASA1 is important in the regulation of free Trp concentration , and that mutation of OASA1 to render the encoded protein insensitive to feedback inhibition results in accumulation of Trp at high levels .
The OASA1 ( D323N ) transgene may prove useful for the generation of crops with an increased Trp content . | Matching Sentences:
