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.

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 goal of this paper was to study the accumulation of selenium ( Se ) in different cultivars of brown rice and its distribution in fractions . The results of the study showed that Se content in brown rice increased significantly ( P < 0 . 01 ) as the external selenite or selenate concentrations increased from 10 to 180 micromol/L In contrast , no significant influence ( P > 0 . 05 ) on germination percentage and growth of sprouts was observed when the supplied Se was lower than 60 micromol/L Moreover , selenite was easily transformed into selenoproteins to selenate . Based on this , ten brown rice cultivars were compared for Se accumulation . Likewise , significant difference ( P < 0 . 01 ) was found among cultivars with respect to the capacity for Se accumulation . To understand the distribution of Se in selenized brown rice and its loss during milling , two cultivars with relatively higher ability to accumulate Se , namely , Zhendao 8 (
Z8
) and Xieyou 57 ( X57 ) , were selected for further study . The results showed that Se content was highest in the sprouts and decreased remarkably ( P < 0 . 01 ) from the bran layers to the endosperm . In terms of Se loss during the milling procedure , 39 . 02% and 48 . 46% of Se were lost in
Z8
and X57 , respectively .
