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].

Abstract: Bread wheat ( Triticum aestivum ) is a hexaploid species with A , B , and D ancestral genomes . Most bread wheat genes are present in the genome as triplicated homoeologous genes ( homoeologs ) derived from the ancestral species . Here , we report that both genetic and epigenetic alterations have occurred in the homoeologs of a wheat class E MADS box gene . Two class E genes are identified in wheat , wheat SEPALLATA ( WSEP ) and wheat LEAFY HULL STERILE1 ( WLHS1 ) , which are homologs of Os MADS45 and Os MADS1 in rice ( Oryza sativa ) , respectively . The three wheat homoeologs of WSEP showed similar genomic structures and expression profiles . By contrast , the three homoeologs of WLHS1 showed genetic and epigenetic alterations . The A genome WLHS1 homoeolog ( WLHS1-A ) had a structural alteration that contained a large novel sequence in place of the K domain sequence . A yeast two-hybrid analysis and a transgenic experiment indicated that the WLHS1-A protein had no apparent function . The B and D genome homoeologs , WLHS1-B and WLHS1-D , respectively , had an intact MADS box gene structure , but WLHS1-B was predominantly silenced by cytosine methylation . Consequently , of the three WLHS1 homoeologs , only WLHS1-D functions in hexaploid wheat . This is a situation where three homoeologs are differentially regulated by genetic and epigenetic mechanisms .
