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: A putative lipase gene EXTRA GLUME1 regulates both empty-glume fate and spikelet development in rice .
Author: Li H Xue D Gao Z Yan M Xu W Xing Z Huang D Qian Q Xue Y
Journal: Plant J Citation: V : 57 P : 593-605 Year: 2009 Type: MEDLINE
Literature: oryza Field: abstract Doc ID: pub18980657 Accession (PMID): 18980657
Abstract: Recent studies have shown that molecular control of inner floral organ identity appears to be largely conserved between monocots and dicots , but little is known regarding the molecular mechanism underlying development of the monocot outer floral organ , a unique floral structure in grasses . In this study , we report the cloning of the rice EXTRA GLUME1 ( EG1 ) gene , a putative lipase gene that specifies empty-glume fate and floral meristem determinacy . In addition to affecting the identity and number of empty glumes , mutations in EG1 caused ectopic floral organs to be formed at each organ whorl or in extra ectopic whorls . Iterative glume-like structures or new floral organ primordia were formed in the presumptive region of the carpel , resulting in an indeterminate floral meristem . EG1 is expressed strongly in inflorescence primordia and weakly in developing floral primordia . We also found that the floral meristem and organ identity gene OsLHS1 showed altered expression with respect to both pattern and levels in the eg1 mutant , and is probably responsible for the pleiotropic floral defects in eg1 . As a putative class III lipase that functionally differs from any known plant lipase , EG1 reveals a novel pathway that regulates rice empty-glume fate and spikelet development .

Title: Distinction by sequence analysis between cdc2 protein kinases involved in cell cycle control and closely related proteins .
Author: Guerrucci MA Goujon P BellER .
Journal: Protein Seq . Data Anal Citation: V : 4 ( 6 ) P : 337-40 Year: 1991 Type: ARTICLE
Literature: oryza Field: abstract Doc ID: pub1812488 Accession (PMID): 1812488
Abstract: Cdc2 proteins are well characterized as protein kinases and are functionally involved in the control of the G2 to M transition during cell division . cdc2 proteins ( cdc2Sp , CDC28 and CDC2Gg ) and proteins sharing a high degree of similarity with cdc2 proteins ( EG1 and DM2C ) , and therefore belonging to the same structural family , were analyzed using Fourier transform of the coded sequences . Characteristic code/frequency pairs ( 0 . 140 , 0 . 148 and 0 . 238 ) distinguish the cdc2 proteins from the related proteins . The frequencies 0 . 140 , 0 . 148 and 0 . 238 ( and the associated codes ) allow discrimination between all cdc2 proteins ( cdc2Sp , CDC28 , CDC2Gg , CDC2Hs , CDC2Mm , CDC2Dm , CDC2Ms ) and related proteins ( EG1 , DM2C , MO15 , GTA , PHO85 , KSS1 , PSKJ3 , FUS3 , KIN28 ) , thus providing the first evidence for predicting cdc2 function from a sequence . A rice cdc2 homolog ( R2 ) did not match the cdc2 proteins and is , therefore , unlikely to be a cdc2 protein . Pertinent patterns in the cdc2 proteins were searched , and mapped to the 90-210 region ( numbering from cdc2 of S pombe ) which correlates well with the putative cyclin binding domain of the cdc2 proteins .
