Diversification of myco-heterotrophic angiosperms: evidence from Burmanniaceae.
ABSTRACT: BACKGROUND: Myco-heterotrophy evolved independently several times during angiosperm evolution. Although many species of myco-heterotrophic plants are highly endemic and long-distance dispersal seems unlikely, some genera are widely dispersed and have pantropical distributions, often with large disjunctions. Traditionally this ...

The small glycine-rich RNA-binding protein AtGRP7 promotes floral transition in Arabidopsis thaliana.
The RNA-binding protein AtGRP7 is part of a circadian slave oscillator in Arabidopsis thaliana that negatively auto-regulates its own mRNA and affects the level of other transcripts. Here we identify a novel role for ...

Soil Bacteria Augment Arabidopsis Photosynthesis by Decreasing Glucose Sensing and Abscisic Acid Levels in planta.
Photosynthesis is regulated by environmental factors as well as endogenous sugar signals. While light-driven sugar biosynthesis is essential for terrestrial organisms as well as belowground micro flora, whether and how soil-symbionts ...

Stimulus-induced down-regulation of root water transport involves reactive oxygen species-activated cell signalling and plasma membrane intrinsic protein internalization.
The water uptake capacity of plants roots (i.e. their hydraulic conductivity, Lp(r)) is determined in large part by aquaporins of the Plasma membrane Intrinsic Protein (PIP) sub-family. In ...

Chilling stress response of post-emergent cotton seedlings.
Early season development of cotton is often impaired by sudden episodes of chilling temperature. We determined the chilling response specific to post-emergent 13-d-old cotton (Gossypium hirsutum L. cv. Coker 100A-glandless) seedlings. Seedlings were gradually chilled during the dark period ...

Diacylglycerol pyrophosphate inhibits the alpha-amylase secretion stimulated by gibberellic acid in barley aleurone.
Abscisic acid (ABA) plays an important regulatory role in seed germination since it inhibits the response to gibberellic acid (GA) in aleurone, a secretory tissue surrounding the endosperm. Phosphatidic acid (PA) is a ...

Increased acquired activated protein C resistance in unselected patients with hematological malignancies.
Background: We have previously found that activation of coagulation in patients with various hematological malignancies was apparently not initiated by tissue factor (TF). Acquired activated protein C (APC) resistance may be another mechanism responsible ...

Targeted mutagenesis of the ring exported protein-1 of Plasmodium falciparum disrupts the architecture of Maurer\'s cleft organelles.
Mature red blood cells have no internal trafficking machinery so the intraerythrocytic malaria parasite, Plasmodium falciparum, establishes its own transport system to export virulence factors to the red blood ...

A previously unidentified s factor and two accessory proteins regulateoxalate decarboxylase expression in Bacillus subtilis.
We have investigated the function of a cell envelope stress inducible gene, yvrI, which encodes a 22.5 kDa protein that includes a predicted sigma(70) region 4 domain, but lacks an apparent ...

Holin of bacteriophage lambda: structural insights into a membrane lesion.
The length of the infection cycle of double-stranded DNA bacteriophages is controlled by phage-encoded small integral membrane proteins, holins. Holins are the gatekeepers of the lysis process, possessing an intriguing ability to be triggered, at a ...

Helicobacter pylori AddAB helicase-nuclease and RecA promote recombination-related DNA repair and survival during stomach colonization.
Helicobacter pylori colonization of the human stomach is characterized by profound disease-causing inflammation. Bacterial proteins that detoxify reactive oxygen species or recognize damaged DNA adducts promote infection, suggesting that H. pylori ...
