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 white spaces (Boolean 'and').
Separate multiple,

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:
An appreciation of the risks caused by emergent plant viruses is critical in tropical areas that rely heavily on agriculture for subsistence and rural livelihood . Molecular ecology , within 10 years , has unraveled the factors responsible for the emergence of several of the economically most important tropical plant viruses : Rice yellow mottle virus ( RYMV ) , Cassava mosaic geminiviruses ( CMGs ) , Maize streak virus ( MSV ) , and Banana streak virus (
BSV
) . A large range of mechanisms--most unsuspected until recently--were involved : recombination and synergism between virus species , new vector biotypes , genome integration of the virus , host adaptation , and long-distance dispersal A complex chain of molecular and ecological events resulted in novel virus-vector-plant-environment interactions that led to virus emergence . It invariably involved a major agricultural change : crop introduction , cultural intensification , germplasm movement , and new genotypes . A current challenge is now to complement the analysis of the causes by an assessment of the risks of emergence . Recent attempts to assess the risks of emergence of virulent virus strains are described .
