[ Sen. 1, subscore: 1.00 ]: A novel population consisting of 35 single-segment substitution lines ( SSSLs ) originating from crosses between the recipient parent , Hua-jing-xian 74 ( HJX74 ) , and 17 donor parents was evaluated in six cropping season environments to reveal the genetic basis of genetic main effect ( G ) and genotype-by-environment interaction effect ( GE ) for panicle number ( PN ) in rice . [ Sen. 4, subscore: 1.00 ]: At least 18 QTLs for PN in rice were detected and identified on 9 of 12 rice chromosomes . [ Sen. 11, subscore: 1.00 ]: Information provided in this paper could be used in the application of marker-assisted selection to manipulate PN in rice .

| Author: Jin YL Jo YY Kim KY Shim JH Kim YW Park RD .
| Journal: J Biochem . Mol . Biol . Citation: V : 35 ( 3 ) P : 313-9 Year: 2002 Type: ARTICLE | Literature: oryza Field: abstract Doc ID: pub12297015 Accession (PMID): 12297015 | Matching Sentences: [ Sen. 6, subscore: 2.00 ]: The enzyme catalyzed the hydrolysis of both p-nitrophenyl-N-acetyl-beta-D-glucosaminide ( pNP-GlcNAc ) and p-nitrophenyl-N-acetyl-beta-D-galactosaminide ( pNPGalNAc ) as substrates , which are typical properties of beta-HexNAcase . [ Sen. 7, subscore: 2.00 ]: The ratio of the pNP-GlcNAcase activity to the pNP-GalNAcase activity was 4 . 0 . [ Sen. 8, subscore: 2.00 ]: However , it could not hydrolyze chitin , chitosan , pNP-beta-glucopyranoside , or pNP-beta-galactopyranoside . [ Sen. 10, subscore: 2.00 ]: The comparison of kinetic values for pNPGlcNAc and pNP-GalNAc revealed that the two enzyme activities are associated with a single binding site . [ Sen. 9, subscore: 1.00 ]: The enzyme showed K ( M ) , V ( max ) and K ( cat ) for pNP-GlcNAc of 1 . 65mM , 79 . 49mM min ( 1 ) , and 4 . 79 x 10 ( 6 ) min ( 1 ) , respectively . [ Sen. 11, subscore: 1.00 ]: The purified enzyme exhibited optimum pH and temperature for pNPGlcNAc of 5 . 0 and 50 degrees C , respectively . [ Sen. 12, subscore: 1.00 ]: The enzyme activity for pNP-GlcNAc was stable at pH 5 . 0-5 . 5 and 20-40 degrees C The enzyme activity was completely inhibited at a concentration of 0 . 1 mM HgCl ( 2 ) and AgNO ( 3 ) , suggesting that the intact thiol group is essential for activity .

Score: 9.00 | Title: A circadian rhythm set by dusk determines the expression of FT homologs and the short-day photoperiodic flowering response in Pharbitis .
| Author: Hayama R Agashe B Luley E King R Coupland G | Journal: Plant Cell Citation: V : 19 P : 2988-3000 Year: 2007 Type: In-Process | Literature: oryza Field: abstract Doc ID: pub17965272 Accession (PMID): 17965272 | Matching Sentences: [ Sen. 8, subscore: 3.00 ]: In these assays , Pn FT mRNA abundance was not related to Pn CO expression , suggesting that Pn FT may be regulated by a different transcription factor in Pharbitis . [ Sen. 4, subscore: 2.00 ]: We studied Pharbitis ( Ipomoea nil ; formerly , Pharbitis nil ) , a widely used SD model species and a member of the Convolvulaceae , and showed using transgenic plants together with detailed expression analysis that two putative orthologs of FT ( Pn FT1 and Pn FT2 ) promote flowering specifically under SDs . [ Sen. 7, subscore: 2.00 ]: Furthermore , Pharbitis accessions that differ in their critical night-length responses express Pn FT at different times after dusk , demonstrating that natural genetic variation influencing the clock regulating Pn FT expression alters the flowering response . [ Sen. 6, subscore: 1.00 ]: We demonstrate that in Pharbitis a circadian rhythm set by the light-to-dark transition at dusk regulates Pn FT expression , which rises only when the night is longer than 11 h . [ Sen. 9, subscore: 1.00 ]: We conclude that SD response in Pharbitis is controlled by a dedicated light sensitive clock , set by dusk , that activates Pn FT transcription in darkness , a different mechanism for measuring daylength than described for Arabidopsis and rice .

Score: 8.00 | Title: [ Analysis of additive and AE interaction effects of QTLs controlling plant height , heading date and panicle number in rice ( Oryza sativa L ) ] | Author: Yuan AP Cao LY Zhuang JY Li RZ Zheng KL Zhu J Cheng SH .
| Journal: Yi Chuan Xue Bao Citation: V : 30 ( 10 ) P : 899-906 Year: 2003 Type: ARTICLE | Literature: oryza Field: abstract Doc ID: pub14669505 Accession (PMID): 14669505 | Matching Sentences: [ Sen. 6, subscore: 2.00 ]: QTLMapper 1 . 01 was applied to detect QTLs and QTL x environment ( QE ) interaction for HD ( heading data ) , PH ( plant height ) and PN ( panicle number ) , and conditional mapping for PH and PN was performed as well . [ Sen. 1, subscore: 1.00 ]: Plant height ( PH ) , heading date ( HD ) and productive panicle number ( PN ) are important agronomic trait in rice . [ Sen. 8, subscore: 1.00 ]: Ten QTLs with additive x additive epistatic effects for PH , HD and PN were detected , among which none showed significant epistatisis x environment interaction . [ Sen. 9, subscore: 1.00 ]: These QTLs explained 12 . 12% , 1 . 38% and 5 . 00% of the total phenotypic variance for PH , HD and PN , respectively , and contributions were generally lower due to the strong epistatic effects . [ Sen. 10, subscore: 1.00 ]: In conditional QTL analysis , the numbers of QTLs showing significant additive and epistatic effects were 7 and 6 for PH , and 3 and 3 for PN , respectively . [ Sen. 12, subscore: 1.00 ]: Each of the 3 QTLs having significant additive effects for PN did not display significant QE interaction . [ Sen. 14, subscore: 1.00 ]: In addition , conditional QTL analysis indicated that the expression of QTLs for PH and PN may vary depending on the QTLs for HD .

| Journal: Acta Biochim . Biophys . Sin . ( Shanghai ) Citation: V : 36 ( 7 ) P : 457-66 Year: 2004 Type: ARTICLE | Literature: oryza Field: abstract Doc ID: pub15248020 Accession (PMID): 15248020 | Matching Sentences: [ Sen. 6, subscore: 2.00 ]: By using five truncated derivatives of Pns6 , it was found that the basic region from amino acid 201 to 273 of Pns6 was the unique nucleic acid binding domain . [ Sen. 2, subscore: 1.00 ]: Pns6 , the 71 kD product of S6 expressed in E coli , was demonstrated to be a viral non-structural protein of RRSV by Western blotting . [ Sen. 3, subscore: 1.00 ]: The gel mobility shift assays showed that Pns6 had nucleic acid binding activity . [ Sen. 4, subscore: 1.00 ]: Pns6 could interact with single and double-stranded forms of DNA and RNA , showing a preference for single-stranded nucleic acid and a slight preference for RRSV ssRNA over the rice ssRNA , as demonstrated by both competition and displacement assays . [ Sen. 5, subscore: 1.00 ]: The binding of Pns6 to nucleic acids is strong and sequence non-specific . [ Sen. 7, subscore: 1.00 ]: Subcellular fractionation of leaf it issues of RRSV-infected rice plants and subsequent Western blotting had shown that Pns6 accumulated predominately in the cytoplasmic membrane fraction . [ Sen. 8, subscore: 1.00 ]: The possible role of RRSV Pns6 in virus replication and assembly is discussed .
