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].

[ Sen. 4, subscore: 7.00 ]: We used the promoter ( P ( Xa13 ) ) of the dominant Xa13 , which was induced by only the incompatible Xoo strain for xa13 , to regulate xa13 and xa13 ( Leu49 ) ( a natural recessive allele of xa13 ) in the rice line IRBB13 carrying xa13 .

[ Sen. 3, subscore: 2.00 ]: Here we show that , compared with its dominant allele , expressional non-reaction of xa13 to Xoo infection , not its protein composition , is the key factor for xa13-mediated resistance .
[ Sen. 2, subscore: 1.00 ]: The molecular mechanism of xa13-mediated resistance is largely unknown .
[ Sen. 7, subscore: 1.00 ]: These results suggest that race-specific pathogen-induced Xa13 expression is critical for infection .
[ Sen. 8, subscore: 1.00 ]: Thus , xa13 stands out from other R genes in that its functions in disease resistance are due to only the loss of pathogen-induced transcriptional motivation caused by natural selection .
