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: Molecular cloning and characterization of a rice dehydroascorbate reductase .
Author: Urano J Nakagawa T Maki Y Masumura T Tanaka K Murata N Ushimaru T
Journal: FEBS Lett . Citation: V : 466 ( 1 ) P : 107-11 Year: 2000 Type: ARTICLE
Literature: oryza Field: abstract Doc ID: pub10648822 Accession (PMID): 10648822
Abstract: Plant dehydroascorbate reductase ( DHAR ) , which re-reduces oxidized ascorbate to maintain an appropriate level of ascorbate , is very important , but no gene or cDNA for plant DHAR has been cloned yet . Here , we describe a cDNA for a rice glutathione-dependent DHAR ( designated DHAR1 ) . A recombinant Dhar1p produced in Escherichia coli was functional The expression sequence tag database suggests that Dhar1p homologs exist in various plants . Furthermore , the rice Dhar1p has a low similarity to rat DHAR , although the rice enzyme has a considerably higher specific activity than the mammalian one . The mRNA level of DHAR1 , the protein level of Dhar1p and the DHAR activity in rice seedlings were elevated by high temperature , suggesting the protection role of DHAR at high temperature .
