Water availability is a significant constraint to crop production, and increasing drought tolerance
of crops is one step to gaining greater yield stability. Excellent progress has been made …

The completion of the Arabidopsis thaliana genome sequence allows a comparative analysis
of transcriptional regulators across the three eukaryotic kingdoms. Arabidopsis dedicates …

APUTATIVE chemokine receptor that we previously cloned and termed LESTR 1 has recently
been shown to function as a co-receptor (termed fusin) for lymphocyte-tropic HIV-1 strains …

Like other pathogenic viruses, HIV–1 down–modulates surface expression of major
histocompatibility complex class I (MHC–I) molecules in infected cells, thus impairing lysis by …

Commercially improved crop performance under drought conditions has been challenging
because of the complexity of the trait and the multitude of factors that influence yield. Here we …

Limited available water is the single most important factor that reduces global crop yields,
with far reaching socioeconomic implications. In North America alone, it is estimated that 40% …

Recognizing that corporate social reporting may soon assume a new significance in the USA,
this article reviews the reasons for this and discusses the responses to date. In looking at …

In this review we highlight recent progress in the study of Rheb family GTPases. Structural
studies using X-ray crystallography and NMR have given us insight into unique features of this …

We have established an Arabidopsis protoplast model system to study plant cell death
signaling. The fungal toxin fumonisin B1 (FB1) induces apoptosis-like programmed cell death (…

The surface expression of MHC I is reduced in HIV-infected cells. We show that the Nef protein
affects the intracellular sorting of HLA-A and -B molecules. In the presence of Nef, these …
