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

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].

Abstract:
Rice blast disease is a major constraint for rice breeding . Nevertheless , the genetic basis of resistance remains poorly understood for most rice varieties , and new resistance genes remain to be identified . We identified the resistance gene corresponding to the cloned avirulence gene ACE1 using pairs of isogenic strains of Magnaporthe grisea differing only by their ACE1 allele . This resistance gene was mapped on the short arm of rice chromosome 8 using progenies from the crosses IR64 ( resistant ) x Azucena ( susceptible ) and Azucena x Bala ( resistant ) . The isogenic strains also permitted the detection of this resistance gene in several rice varieties , including the differential isogenic line C101LAC . Allelism tests permitted us to distinguish this gene from two other resistance genes [
Pi11
and Pi-29 ( t ) ] that are present on the short arm of chromosome 8 . Segregation analysis in F ( 2 ) populations was in agreement with the existence of a single dominant gene , designated as Pi33 . Finally , Pi33 was finely mapped between two molecular markers of the rice genetic map that are separated by a distance of 1 . 6 cM . Detection of Pi33 in different semi-dwarf indica varieties indicated that this gene could originate from either one or a few varieties .
