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].

[ Sen. 6, subscore: 1.00 ]:
Membrane trafficking between the plasma membrane ( PM ) and intracellular compartments is an important process that regulates the deposition and metabolism of cell wall polysaccharides . Dynamin-related proteins ( DRPs ) , which function in membrane tubulation and vesiculation are closely associated with cell wall biogenesis . However , the molecular mechanisms by which DRPs participate in cell wall formation are poorly understood . Here , we report the functional characterization of Brittle Culm3 ( BC3 ) , a gene encoding OsDRP2B . Consistent with the expression of BC3 in mechanical it issues , the bc3 mutation reduces mechanical strength , which results from decreased cellulose content and altered secondary wall structure .
OsDRP2B , one of three members of the
DRP2
subfamily in rice ( Oryza sativa L ) , was identified as an authentic membrane-associated dynamin via in vitro biochemical analyses .
Subcellular localization of fluorescence-tagged OsDRP2B and several compartment markers in protoplast cells showed that this protein not only lies at the PM and the clathrin-mediated vesicles , but also is targeted to the trans-Golgi network ( TGN ) . An FM4-64 uptake assay in transgenic plants that express green fluorescent protein-tagged OsDRP2B verified its involvement in an endocytic pathway . BC3 mutation and overexpression altered the abundance of cellulose synthase catalytic subunit 4 ( OsCESA4 ) in the PM and in the endomembrane systems . All of these findings lead us to conclude that OsDRP2B participates in the endocytic pathway , probably as well as in post-Golgi membrane trafficking . Mutation of OsDRP2B disturbs the membrane trafficking that is essential for normal cellulose biosynthesis of the secondary cell wall , thereby leading to inferior mechanical properties in rice plants .
