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,

keywords by white spaces (Boolean 'and').
Separate multiple,

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:
Drought is one of the most significant abiotic stresses that influence plant growth and development . Expression analysis revealed that OsNRT1 . 3 , a putative nitrate transporter gene in rice , was induced by drought . To confirm if the OsNRT1 . 3 promoter can respond to drought stress , a 2019 bp upstream sequence of OsNRT1 . 3 was cloned . Three OsNRT1 . 3 promoter fragments were generated by 5-deletion , and fused to the beta-glucuronidase ( GUS ) gene . The chimeric genes were introduced into rice plants .
NRT2019
: : GUS , NRT1196 : : GUS and NRT719 : : GUS showed similar expression patterns in seeds , roots , leaves and flowers in all transgenic rice , and GUS activity conferred by different OsNRT1 . 3 promoter fragments was significantly upregulated by drought stress , indicating that OsNRT1 . 3 promoter responds to drought stress and the 719 bp upstream sequence of OsNRT1 . 3 contains the drought response elements .
