Sugar transporters for intercellular exchange and nutrition of pathogens
TLDR
Using optical glucose sensors, a new class of sugar transporters are identified, named SWEETs, and it is shown that at least six out of seventeen Arabidopsis, two out of over twenty rice and two of seven homologues in Caenorhabditis elegans, and the single copy human protein, mediate glucose transport.

A genome-wide transcriptional analysis using Arabidopsis thaliana Affymetrix gene chips determined plant responses to phosphate deprivation.
TLDR
A detailed analysis of Pi starvation-induced changes in gene expression of the entire genome of Arabidopsis correlated with biochemical processes enhances knowledge about molecular processes associated with Pi deficiency, but also facilitates the identification of key molecular determinants for improving Pi use by crop species. Expand
Coordinated plant defense responses in Arabidopsis revealed by microarray analysis.
TLDR
The results indicated the existence of a substantial network of regulatory interactions and coordination occurring during plant defense among the different defense signaling pathways, notably between the salicylate and jasmonate pathways that were previously thought to act in an antagonistic fashion. Expand
SNARE-protein-mediated disease resistance at the plant cell wall
TLDR
It is shown that resistance in barley requires a SNAP-25 (synaptosome-associated protein, molecular mass 25 kDa) homologue capable of forming a binary SNAP receptor (SNARE) complex with ROR2, and functions associated with SNARE-dependent penetration resistance are dispensable for immunity mediated by race-specific resistance (R) genes, highlighting fundamental differences between these two resistance forms.

Arabidopsis PEN3/PDR8, an ATP Binding Cassette Transporter, Contributes to Nonhost Resistance to Inappropriate Pathogens That Enter by Direct Penetration[W][OA]
Arabidopsis thaliana is a host to the powdery mildew Erysiphe cichoracearum and nonhost to Blumeria graminis f. sp hordei, the powdery mildew pathogenic on barley (Hordeum vulgare). Screening forExpand
Pre- and Postinvasion Defenses Both Contribute to Nonhost Resistance in Arabidopsis
TLDR
It is reported that Arabidopsis PEN2 restricts pathogen entry of two ascomycete powdery mildew fungi that in nature colonize grass and pea species. Expand
Loss of a Callose Synthase Results in Salicylic Acid-Dependent Disease Resistance
TLDR
It is found that powdery mildew resistant 4 (pmr4), a mutant lacking pathogen-induced callose, became resistant to pathogens, rather than more susceptible, due to mutation of a callose synthase, resulting in a loss of the induced callose response. Expand
Conserved requirement for a plant host cell protein in powdery mildew pathogenesis
TLDR
A conserved requirement for MLO proteins in powdery mildew pathogenesis in the dicotyledonous plant species Arabidopsis thaliana is demonstrated, suggesting that within the Erysiphales (powdery mildews) the ability to cause disease has been a stable trait throughout phylogenesis. Expand
Expression Profile Analysis of the Low-Oxygen Response in Arabidopsis Root Cultures Online version contains Web-only data. Article, publication date, and citation information can be found at
TLDR
It is found that the regulatory regions of genes with a similar expression profile contained similar sequence motifs, suggesting the coordinated transcriptional control of groups of genes by common sets of regulatory factors. Expand
Genes Galore: A Summary of Methods for Accessing Results from Large-Scale Partial Sequencing of Anonymous Arabidopsis cDNA Clones
TLDR
The more than 13,400 plant ESTs that are currently available provide a new resource that will facilitate progress in many areas of plant biology and are illustrated by a description of the results obtained from analysis of 1500 Arabidopsis ESTs from a cDNA library prepared from equal portions of poly(A+) mRNA from etiolated seedlings, roots, leaves, and flowering inflorescence.
