Journal ArticleDOI
The Pseudomonas syringae type III-secreted protein HopPtoD2 possesses protein tyrosine phosphatase activity and suppresses programmed cell death in plants.
TL;DR: The identification of HopPtoD2 as a PTP and a PCD suppressor suggests that the inactivation of MAPK pathways is a virulence strategy utilized by bacterial plant pathogens.
Journal ArticleDOI
Disabling surveillance: bacterial type III secretion system effectors that suppress innate immunity.
Avelina Espinosa,James R. Alfano +1 more
TL;DR: Type III effectors can suppress signal transduction pathways activated by PRR surveillance systems, which will reveal much about bacterial pathogenicity and the innate immune system in plants and animals.
Journal ArticleDOI
The Bifunctional Entamoeba histolytica Alcohol Dehydrogenase 2 (EhADH2) Protein Is Necessary for Amebic Growth and Survival and Requires an Intact C-terminal Domain for Both Alcohol Dehydrogenase and Acetaldehyde Dehydrogenase Activity
TL;DR: It is shown that EhADH2 enzyme is required for E. histolytica growth and survival and that the C-terminal ADH domain of the enzyme functions as a separate entity, however, ALDH activity requires residues in both the N- and C-Terminal halves of the molecule.
Journal ArticleDOI
Acceptance of Evolution Increases with Student Academic Level: A Comparison Between a Secular and a Religious College
TL;DR: Overall acceptance of evolution among biologists (S or R) increased gradually from the freshman to the senior year, due to exposure to upper-division courses with evolutionary content.
Journal ArticleDOI
Assessment of Biology Majors’ Versus Nonmajors’ Views on Evolution, Creationism, and Intelligent Design
TL;DR: Combined open plus private acceptance of evolution within biology majors increased with seniority, from freshman to seniors, presumably due to gradual exposure to upper-division biology courses with evolutionary content.
