| Title: Organization of the 1 . 9-kb repeat unit RCE1 in the centromeric region of rice chromosomes .
| | Author: Nonomura KI Kurata N | | Journal: Mol . Gen . Genet . Citation: V : 261 ( 1 ) P : 1-10 Year: 1999 Type: ARTICLE | | Literature: oryza Field: abstract Doc ID: pub10071204 Accession (PMID): 10071204 | | Abstract: This paper presents the first report on the structure of a 14-kb centromere sequence in a cereal genome that includes 1 . 9-kb direct repeats .
The cereal centromeric sequence ( CCS1 ) conserved in some Gramineae species contains a 17-bp motif similar to the CENP-B box , which serves as the binding site for the centromere-specific protein CENP-B in human .
To isolate centromeric units from rice ( Oryza sativa L ) , we performed PCR using the CENP-B box-like sequences ( CBLS ) as primers .
A 264-bp clone was amplified by this method , and called RCS1516 .
It appeared to be a novel member of the CCS1 family , sharing about 60% identity with the CCS1 sequences of other cereals .
Then , a 14-kb genomic clone , lambda RCB11 , carrying the RCS1516 sequence was isolated and sequenced .
It was found to contain three copies of a 1 . 9-kb direct repeat , RCE1 , separated by 5 . 1 and 1 . 7-kb .
A 300-bp sequence at the 3 end of RCE1 is highly conserved in all three copies ( >90% ) and is almost identical to the RCS1516 sequence including the CBLS motif .
The copy number of RCE1 was estimated to range from 10 ( 2 ) to 10 ( 3 ) in the haploid genome of rice .
Cloned RCE1 units were used for fluorescent in situ hybridization ( FISH ) analysis , and signals were observed on almost every primary constriction of rice chromosomes .
Thus it was concluded that RCE1 is a significant component of the rice centromere .
The lambda RCB11 clone contained at least four A/T-rich regions , which are candidate for matrix attachment regions ( MARs ) , in the sequences between the RCE1 repeats .
Other elements that are homologous to the short centromeric repetitive sequences pSau3A9 and pRG5 , detected in both sorghum and rice , were also found in the clone . | Matching Sentences:
[ Sen. 9, subscore: 1.00 ]: The copy number of RCE1 was estimated to range from 10 ( 2 ) to 10 ( 3 ) in the haploid genome of rice .

| Title: Needs assessment following hurricane Georges--Dominican Republic , 1998 .
| | Author: . | | Journal: MMWR Morb .
Mortal Wkly . Rep . Citation: V : 48 ( 5 ) P : 93-5 Year: 1999 Type: ARTICLE | | Literature: oryza Field: abstract Doc ID: pub10072265 Accession (PMID): 10072265 | | Abstract: Hurricane Georges struck the Carribean Islands in September 1998 , causing numerous deaths and extensive damage throughout the region .
The Dominican Republic was hardest hit , with approximately 300 deaths ; extensive infrastructure damage ; and severe agricultural losses , including staple crops of rice , plantain , and cassava .
Two months after the hurricane , the American Red Cross ( ARC ) was asked to provide food to an estimated 170 , 000 families affected by the storm throughout the country .
To assist in directing relief efforts , CDC performed a needs assessment to estimate the food and water availability , sanitation , and medical needs of the hurricane-affected population .
This report summarizes the results of that assessment , which indicate that , 2 months after the disaster , 40% of selected families had insufficient food > or =5 days per and 28% of families reported someone in need of medical attention .

| Title: Use of urea-molasses-multinutrient block and urea-treated rice straw for improving dairy cattle productivity in Vietnam .
| | Author: Vu DD Cuong LX Dung CA Hai PH .
| | Journal: Prev . Vet . Med . Citation: V : 38 ( 2-3 ) P : 187-93 Year: 1999 Type: ARTICLE | | Literature: oryza Field: abstract Doc ID: pub10081798 Accession (PMID): 10081798 | | Abstract: After conducting a preliminary survey , a feeding trial was carried out to determine the effect of urea-molasses-multinutrient block ( UMMB ) and urea-treated rice straw ( UTRS ) as a feed supplement on the productivity of dairy cows .
Sixty Holstein-Friesian crossbred cows on 11 smallholder farms were divided equally into control , UMMB and UTRS supplementation groups .
Milk yield and feed intake were recorded daily .
Milk fat content , body weight and body condition score ( BSC ) of each cow were determined at two week intervals .
Milk samples for progesterone analysis were collected once a week commencing one month after parturition .
Data were recorded for date of onset of ovarian activity , estrus , insemination , and conception rate .
Milk production increased by 10 . 3-11 . 9% and milk fat content increased by 3-5% , therefore , profit for farmers increased by US $0 . 55-0 . 73 per cow per day ( exchange rate US $1 = VN $11 , 000 ) .
The intervals from calving to onset of ovarian activity ( 91-94 days ) , to estrus ( 110-114 days ) , to conception ( 121-122 days ) and the calving interval ( 13 . 4-13 . 6 months ) in the trial groups were significantly shorter than those in the control group ( 112 , 135 , 152 days and 14 . 4 months , respectively . | Matching Sentences:
