Title: Gooey seeds: goo-d in your food, goo-d for your guts
Abstract: Seeds of many plant species become surrounded by a viscous hydrogel called mucilage upon contact with water and it has great utility as an affordable and effective food additive and bulking dietary fibre. However commercial seed mucilage-producing plants like psyllium (Plantago ovata) are typically orphan crops and are plagued by agronomic constraints. The production constraints of psyllium are also compounded by high amounts of waste during processing, where the non-mucilage-containing tissues are discarded even though they likely contain many beneficial nutrients. To simultaneously address the agronomic and waste constraints in psyllium production, the composition and functionality of whole seeds of commercial psyllium was compared to six relatives adapted to Australian conditions.

Title: “Identification of an intracellular transporter that regulates pH and impacts osmotic stress tolerance”
Abstract: Ion transport across cellular membranes is essential for the viability of all organisms. This includes both ion transport into and out of cells, as well as across the membranes of intracellular organelles. One such organelle is the Trans-Golgi Network (TGN/EE), which is vital for the sorting and delivery of proteins in cells. Ion transport is typically mediated by membrane-spanning ion transport proteins. Together with a proton pump, ion transporters maintain the low luminal pH of the TGN/EE. The regulation of this pH is an important aspect for TGN/EE function and therefore endomembrane trafficking. We identified and characterised a new regulator of TGN/EE pH in Arabidopsis, the cation chloride cotransporter, AtCCC1.
