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:
The DMC1 protein , a meiosis-specific DNA recombinase , catalyzes strand exchange between homologous chromosomes . In rice , two Dmc1 genes , Dmc1A and
Dmc1B
, have been reported . Although the Oryza sativa DMC1A protein has been partially characterized , however the biochemical properties of the
DMC1B
protein have not been defined . In the present study , we expressed the Oryza sativa DMC1A and
DMC1B
proteins in bacteria and purified them . The purified DMC1A and
DMC1B
proteins formed helical filaments along single-stranded DNA ( ssDNA ) and double-stranded DNA ( dsDNA ) , and promoted robust strand exchange between ssDNA and dsDNA over five thousand base pairs in the presence of RPA , as a co-factor . The DMC1A and
DMC1B
proteins also promoted strand exchange in the absence of RPA with long DNA substrates containing several thousand base pairs . In contrast , the human DMC1 protein strictly required RPA to promote strand exchange with these long DNA substrates . The strand-exchange activity of the Oryza sativa DMC1A protein was much higher than that of the
DMC1B
protein . Consistently , the DNA-binding activity of the DMC1A protein was higher than that of the
DMC1B
protein . These biochemical differences between the DMC1A and
DMC1B
proteins may provide important insight into their functional differences during meiosis in rice .
