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:
Biotrophic fungi interacting with plants establish long-term relationships with their hosts to fulfill their life cycles . In contrast to necrotrophs , they need to contend with the defense mechanisms of the plant to develop within the host and feed on living cells . It is generally accepted that microbial pathogens produce and deliver a myriad of effector proteins to hijack the cellular program of their hosts . Arbuscular mycorrhizal ( AM ) fungi are the most widespread biotrophs of plant roots . We investigated whether AM fungi use effector proteins to short-circuit the plant defense program . Here we show that Glomus intraradices secretes a protein , SP7 , that interacts with the pathogenesis-related transcription factor
ERF19
in the plant nucleus .
ERF19
is highly induced in roots by the fungal pathogen Colletotrichum trifolii as well as by several fungal extracts , but only transiently during mycorrhiza colonization . When constitutively expressed in roots , SP7 leads to higher mycorrhization while reducing the levels of C trifolii-mediated defense responses . Furthermore , expression of SP7 in the rice blast fungus Magnaporthe oryzae attenuates root decay symptoms . Taken together , these results suggest that SP7 is an effector that contributes to develop the biotrophic status of AM fungi in roots by counteracting the plant immune program .
