Early detection of a pathogen attack can prevent the spread of an infection. But how this early detection is then translated into warning for the rest of the plant is not known. Now British researchers show in Nature Plants using a reporter system that the alarm passes through the plant much faster than first thought.

Creating an oxygen-restricted niche
Plants, just like us, need oxygen, but their growth centre, there where the leaves and stems emerge, is surprisingly low on oxygen. There, there is four to six times less than in the air outside the plant. Now a group of international researchers show in Molecular Plant how a plant establishes and maintains this low oxygen niche.
Een zuurstofarme niche creëren
Planten hebben, net als wij, zuurstof nodig. Maar opvallend genoeg is hun groeicenter, daar waar de bladeren en stengels uitkomen, verassend genoeg zuurstofarm. Daar is vier tot zes keer minder zuurstof dan in de lucht buiten de plant. Nu laat een groep van internationale onderzoekers in Molecular Plant zien hoe planten deze zuurstofarme niche creëren.
Seed banks shape gene drive outcomes
Seeds have this amazing ability to lay dormant in the soil for many years. As such, although genes are transferred from one generation to the next, that next generation isn’t always directly following the previous one. This makes studying the outcome of plant reproduction more complex. Now a new paper in Nature Plants shows how seed dormancy influences the success of gene drives.
