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

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:
Plant microRNAs ( miRNAs ) act as negative regulators of gene expression by slicing target transcripts or inhibiting translation . A number of miRNAs play important roles in development . In order to investigate the potential function of miRNAs during male gametogenesis in rice , we obtained both gene and small RNA expression profiles by combining microarray and high-throughput sequencing technologies . From the microarray datasets , 2 , 925 male gametophyte-specific genes were identified , including 107 transcription factors and three significant Argonaute genes ( AGO12 , AGO13 , and
AGO17
) . From the sRNA-Seq datasets , 104 unique miRNAs ( miRus ) were identified , including 47 known miRus and 57 novel miRus ; interestingly , most of the new miRus are pollen-specific and not conserved among species . Furthermore , an interactive network of miRNA-target was constructed based on the two datasets . By employing enrichment analysis , the miRNA-regulated targets were found to be involved in both the up and down pathways , but predominantly in the down pathways , including 37 GO biological processes and 32 KEGG pathways . These findings indicate that miRNAs play a broad regulatory role during male gametophyte development in rice .
