A team has clarified how in plants the boric acid channels, the conduits for the necessary element boron, are transported to the plasma membrane. Botanists have come to understand the channels and ...

Channels in plant cell walls, called plasmodesmata, provide molecules with a bridge to move between cells, an essential phenomenon for cellular growth and development. The mystery has long been how ...

Study details how nutrient-starved cells divert protein transport stations to cellular recycling centers to be broken down, highlighting a novel approach cells use to deal with stressful conditions. A ...

Boron is an essential micronutrient required for plant cell wall integrity, as it is necessary for crosslinking the pectic polysaccharide rhamnogalacturonan II. Reproductive organs require a greater ...

Researchers in Bochum have discovered a control mechanism that may also operate beyond plants. Proteins carrying a "tail anchor" must be inserted into the ER membrane before they can fulfill their ...
