Vesicular transport and salt tolerance

Flowers et al. collect data on the rates of sodium transport found in halophytes and outline vesicle transport systems in general. They conclude there is strong evidence in favour of vesicular transport in plants and circumstantial evidence in favour of the movement of ions in vesicles.

Calcium signals are necessary to establish auxin transporter polarity in a plant stem cell niche

Scientists show that mechanical stimulation of the SAM (shoot apical meristems) causes transient changes in cytoplasmic calcium ion concentration (Ca2+) and that transient Ca2+ response is required for downstream changes in PIN-polarity.

Biologists answer fundamental question about cell size

Biologists have discovered why cell sizes are so tightly regulated. Researchers found that the need to produce just the right amount of protein is behind the striking uniformity of sizes.

Living together: How legume roots accommodate two distinct microbial partners

A research team including University of Tsukuba identifies a gene that controls how legume roots form biological partnerships with two completely different types of microbe -- bacteria and fungi -- that both help supply nutrients.

Cell editors correct genetic errors

Almost all land plants employ an army of editors who correct errors in their genetic information. Researchers have now transferred parts of this machinery into a bacterium. Their results confirm a controversial thesis on the functioning of this widespread mechanism.

Duons that regulate the spatial patterning of gene expression in planta

Duons are so-called because they represent DNA sequence that plays a dual role in coding for amino acids but also in transcription factor binding and thus gene regulation.
