About Textpresso Categories/Ontology Copyright Downloads Feedback Home Query Language Search User Guide
Enter keyword(s) and/or category/ies. Selecting categories for a query makes a search more specific. For example, you can retrieve sentences that contain the word HSN and a Oryza sativa gene name by typing the keyword 'SPW1' and choosing the category 'gene (Oryza sativa)'. A category hit occurs when a particular word or phrase in the sentence is defined as a member of a particular category. Categories will be concatenated by a Boolean 'and' operation to other categories and keyword(s) if present. To search for terms in categories, click on the Categories/Ontology link above.
Keywords
Separate multiple, required keywords by white spaces (Boolean 'and').
Separate multiple, alternative keywords by a comma with no white spaces (Boolean 'or').
Enter phrases in double quotes, and put a '-' sign in front of words which are to be excluded.

Narrow your search results with filter:
Put a '+' sign in front of words which have to be included, a '-' sign in front of words which have to be excluded. Enter the field of the word, viz author, title, year, journal, abstract, type or sentence in square brackets. Enter phrases in double quotes.
For example, to find all the papers in the search result that have Jack as author, but not John, enter +Jack-John[author]. To exclude all papers that have the phrase double mutant in title, enter -"double mutant"[title]. You can combine several filters and enter something like +Jack-John[author] -"double mutant"[title] +1994[year] -review[type].

Title: Differentially and developmentally regulated expression of three rice sucrose synthase genes .
Author: Wang AY Kao MH Yang WH Sayion Y Liu LF Lee PD Su JC .
Journal: Plant Cell Physiol . Citation: V : 40 ( 8 ) P : 800-7 Year: 1999 Type: ARTICLE
Literature: oryza Field: abstract Doc ID: pub10555303 Accession (PMID): 10555303
Abstract: The spatial and temporal distribution of sucrose synthase ( RSuS ) in rice ( Oryza sativa L ) was studied by Western and immunohistochemical analyses using the monospecific antibodies for three RSuS isoforms . In leaf it issues , RSuS1 was localized in the mesophyll while RSuS2 was in the phloem in addition to the mesophyll . In the roots , only RSuS1 was found in the phloem . No RSuS3 could be detected in any parts of etiolated seedlings . The expression of each RSus gene is closely linked to the seed development . RSuS1 was present in the aleurone layers of developing seeds , and at a low level in endosperm cells . RSuS2 was evenly distributed in seed it issues other than the endosperm . RSuS3 was localized predominantly in the endosperm cells . The it issue specific localizations of the three gene products suggest that RSuS1 plays a role in sugar transport into endosperm cells where the reaction catalyzed by RSuS3 provides the precursor of starch synthesis . RSus2 , which is ubiquitously expressed , may play a housekeeping role .

[ Sen. 2, subscore: 1.00 ]: In leaf it issues , RSuS1 was localized in the mesophyll while RSuS2 was in the phloem in addition to the mesophyll .

[ Sen. 10, subscore: 1.00 ]: RSus2 , which is ubiquitously expressed , may play a housekeeping role .

Title: Complete structures of three rice sucrose synthase isogenes and differential regulation of their expressions .
Author: Huang JW Chen JT Yu WP Shyur LF Wang AY Sung HY Lee PD Su JC .
Journal: Biosci . Biotechnol . Biochem . Citation: V : 60 ( 2 ) P : 233-9 Year: 1996 Type: ARTICLE
Literature: oryza Field: abstract Doc ID: pub9063969 Accession (PMID): 9063969
Abstract: By cloning and sequencing cDNA and genomic DNA and transcription initiation site mapping , the total structures including at least 1 kb of putative regulatory sequences upstream of the transcription initiation sites of three genes encoding rice sucrose synthase isoprotomers were either newly established or amended . The third type of SS gene , RSus3 , has not been found in other plants . The structures of the three genes and the gene products were compared and their evolutionary sequence was proposed . Specific probes for the three SS mRNAs were developed and used for analyzing their steady state levels at different organs and under some physiological stress conditions . It appears that RSus2 is a house-keeping gene , RSus3 is highly specific to the grain , and the expression of RSus1 shows a tendency to complement that of RSus3 . A possible cause of the presence of the third rice SS gene was discussed . We also reported a novel method to synthesize single-stranded DNA for S1 mapping of a transcription initiation site associated with extended secondary structures .
Matching Sentences:
[ Sen. 5, subscore: 1.00 ]: It appears that RSus2 is a house-keeping gene , RSus3 is highly specific to the grain , and the expression of RSus1 shows a tendency to complement that of RSus3 .
