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 of Sdr4 , a regulator involved in seed dormancy and domestication of rice .
Author: Sugimoto K Takeuchi Y Ebana K Miyao A Hirochika H Hara N Ishiyama K Kobayashi M Ban Y Hattori T Yano M
Journal: Proc Natl Acad Sci U S A Citation: V : 107 P : 5792-7 Year: 2010 Type: MEDLINE
Literature: oryza Field: abstract Doc ID: pub20220098 Accession (PMID): 20220098
Abstract: Seed dormancy provides a strategy for flowering plants to survive adverse natural conditions . It is also an important agronomic trait affecting grain yield , quality , and processing performance . We cloned a rice quantitative trait locus , Sdr4 , which contributes substantially to differences in seed dormancy between japonica ( Nipponbare ) and indica ( Kasalath ) cultivars . Sdr4 expression is positively regulated by OsVP1 , a global regulator of seed maturation , and in turn positively regulates potential regulators of seed dormancy and represses the expression of postgerminative genes , suggesting that Sdr4 acts as an intermediate regulator of dormancy in the seed maturation program . Japonica cultivars have only the Nipponbare allele ( Sdr4-n ) , which endows reduced dormancy , whereas both the Kasalath allele ( Srd4-k ) and Sdr4-n are widely distributed in the indica group , indicating prevalent introgression . Srd4-k also is found in the wild ancestor Oryza rufipogon , whereas Sdr4-n appears to have been produced through at least two mutation events from the closest O rufipogon allele among the accessions examined . These results are discussed with respect to possible selection of the allele during the domestication process .
