Journal ArticleDOI
Plant Stomata Function in Innate Immunity against Bacterial Invasion
TL;DR: Examination of stomatal guard cells of Arabidopsis provides evidence that supports a model in which stomata, as part of an integral innate immune system, act as a barrier against bacterial infection.
Journal ArticleDOI
Sugar transporters for intercellular exchange and nutrition of pathogens
Li Qing Chen,Bi Huei Hou,Sylvie Lalonde,Hitomi Takanaga,Mara L. Hartung,Xiao Qing Qu,Woei Jiun Guo,Jung Gun Kim,William Underwood,Bhavna Chaudhuri,Diane Chermak,Ginny Antony,Frank F. White,Shauna Somerville,Mary Beth Mudgett,Wolf B. Frommer +15 more
TL;DR: 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.
Journal ArticleDOI
Role of Stomata in Plant Innate Immunity and Foliar Bacterial Diseases
TL;DR: It is shown that stomata can play an active role in limiting bacterial invasion as part of the plant innate immune system, and microbial and environmental regulation of stomatal closure and opening could fill gaps in the understanding of bacterial pathogenesis, disease epidemiology, and microbiology of the phyllosphere.
Journal ArticleDOI
Mitogen-Activated Protein Kinases 3 and 6 Are Required for Full Priming of Stress Responses in Arabidopsis thaliana
Gerold J. M. Beckers,Michal Jaskiewicz,Yidong Liu,William Underwood,Sheng Yang He,Shuqun Zhang,Uwe Conrath +6 more
TL;DR: It is shown that during development of chemically induced resistance in Arabidopsis thaliana, priming is associated with accumulation of mRNA and inactive proteins of mitogen-activated protein kinases (MPKs), MPK3 and MPK6.
Journal ArticleDOI
Genome-wide transcriptional analysis of the Arabidopsis thaliana interaction with the plant pathogen Pseudomonas syringae pv. tomato DC3000 and the human pathogen Escherichia coli O157:H7.
TL;DR: Regulation of these genes provides a molecular signature for Arabidopsis basal defense to plant and human pathogenic bacteria, and illustrates both common and distinct global virulence effects of the TTSS, COR, and possibly other hrp-regulated virulence factors during Pst DC3000 infection.
