Salt cress (Thellungiella halophila) is a small winter annual crucifer with a short life cycle. It has a small genome (about 2 x Arabidopsis) with high sequence identity (average 92%) with Arabidopsis, and can be genetically transformed by the simple floral dip procedure. It is capable of copious seed production. Salt cress is an extremophile native to(More)
BACKGROUND & AIMS Progression of diseases of the exocrine pancreas, which include pancreatitis and cancer, is associated with increased levels of cell stress. Pancreatic acinar cells are involved in development of these diseases and, because of their high level of protein output, they require an efficient, unfolded protein response (UPR) that mediates(More)
To identify the genetic loci that control salt tolerance in higher plants, a large-scale screen was conducted with a bialaphos marker-based T-DNA insertional collection of Arabidopsis ecotype C24 mutants. One line, osm1 (for osmotic stress-sensitive mutant), exhibited increased sensitivity to both ionic (NaCl) and nonionic (mannitol) osmotic stress in a(More)
Higher plants possess several classes of peroxisomes that are present at distinct developmental stages and serve different metabolic roles. To investigate the cellular processes that regulate developmental transitions of peroxisomal function, we analyzed the targeting of glyoxysomal proteins to leaf-type and root peroxisomes. We transferred genes encoding(More)
Higher plant proteins immunologically related to the animal substrate adhesion molecule vitronectin have recently been observed and implicated in a variety of biological processes, such as plasma membrane-cell wall adhesion, pollen tube extension, and bacterium-plant interaction. We provide evidence that, similar to vitronectin, one of these proteins, PVN1(More)
, 140 words Total characters with spaces, 52,822 3 Summary The antifungal activity of the PR-5 family of plant defense proteins has been suspected to involve specific plasma membrane component(s) of the fungal target. Osmotin is a tobacco PR-5 family protein that induces apoptosis in the yeast Saccharomyces cerevisiae. We show here that the protein encoded(More)
